Promising effects of vinasse use on bone strength in laying hens.

This study was carried out to determine the effects of vinasse on bone strength and some material properties in laying hens with specific amounts of vinasse added to their diets. The study was the first to determine the mechanical properties of laying hens fed a diet supplemented with vinasse. The study was conducted on tibiotarsi of two hundred 94-week-old laying hens which were selected randomly from a commercial farm. Morphometric measurements were made using a digital scale and caliper, and mechanical data were collected from tibiotarsi using a three-point bending test with a compression-tension machine. The laying hens fed with vinasse had higher tibiotarsal length and weight than those in Control group. The groups fed with vinasse were significantly stiffer and had a higher breaking force than Control group (P=0.002, P

Resistance evaluation of Canna indica, Cyperus papyrus, Iris sibirica, and Typha latifolia to phytotoxic characteristics of diluted tequila vinasses in wetland microcosms

Tequila vinasse has a high contaminating capacity due to its physicochemical characteristics. Efficient and low-cost alternative treatments are required to reduce and control the environmental impacts caused by raw vinasse discharges, mainly from micro and small factories. One option is wetland technologies in which vegetation plays an important role in the proper functioning of the system; thus, the species to be used must be properly selected based on their resistance and tolerance to the toxic effects of vinasse. Therefore, this study aims to evaluate the resistance of four macrophyte species to tequila vinasse in wetland microcosms that is, Canna indica, Cyperus papyrus, Iris sibirica, and Typha latifolia which were exposed to 5, 7, 10, 12, and 15% of vinasse diluted with domestic wastewater. The control parameters (relative content, evapotranspiration, pH, electrical conductivity, and apparent color) showed that the plants in general developed stress symptoms. However, statistical analysis revealed a significant difference (p < 0.05) between plant species and vinasse treatments, further evidencing that I. sibirica is the species with the greatest potential to be used as emergent vegetation in treatment wetlands for the purification of tequila vinasse.

Vinasse and straw retention decrease fungal diversity and pathogenicity in sugarcane soil / Aplicação de vinhaça e retenção de palha diminuem a diversidade e patogenicidade de fungos em solo canavieiro

This study focused on the effects of vinasse (V), a by-product of the sugar-ethanol industry, combined with mineral nitrogen fertilizer (N) and straw retention on the fungal community diversity, composition, and structure in a sugarcane-cultivated soil. The experiment consisted of a combination of V, mineral N and sugarcane-straw blanket. Soil samples were collected at 7, 157, and 217 days after planting, corresponding to maximum carbon dioxide emissions from soil after three repeated applications of fertilizers into the soil. Across 57 soil metagenomics datasets, it was revealed that the application the V in combination with N fertilizer and straw retention decreased the diversity, evenness and richness of fungi at the community level in soil. Analysis of the soil fungal community composition based on the 20 genera most abundant revealed decrease for Blastomyces, Melampsora, and Penicillium after the third application of V in combination with N fertilizer and straw blanket. An opposite response was revealed for Amauroascus, Cantharellus, Chrysosporium, Clavaria, Morchella, Puccinia, and Tuber in soil under this treatment. Shifts in fungal community composition were followed by increases in mycorrhizal and decomposers soil-borne fungi and decrease in potentially pathogenic fungi, but not by changes in community structure. Based on these results, it is possible to attest that repeated applications of V in combination with N fertilizer and sugarcane-straw blankets affect ecological aspects of the soil fungal community composition and potential functions played by fungi in sugarcane soil, which are essentials to ecosystem function and sustainable management of agricultural ecosystems.

Effect of Sugar and Alcohol Industry Byproducts on Pre-Emergence Herbicide Efficacy

The present study evaluate the effects of vinasse and filter cake on the efficacy of indaziflam, saflufenacil, and sulfentrazone for the control of morning glory (Ipomoea triloba L.) and crabgrass (Digitaria horizontalis Wiild), as well as the effects of these byproducts on the emergence of these weeds. The experiments were established in a greenhouse with a completely randomized design and four replications at the Agricultural Science Center, Sao Paulo, Brazil, between May 2017 and May 2018. In the first assay, four herbicide doses: indaziflam (0, 37.5, 75, and 150 g ai ha-1), saflufenacil (0, 42, 84, and 168 g a.i ha-1), and sulfentrazone (0, 300, 600, and 1200 g ai ha-1) were applied for pre-emergent weeds in three soil covers (without byproduct, with vinasse, and with filter cake).In the second assay, seven treatments were evaluated, comparing the effects of the different vinasse and filter cake doses, and absence of byproduct on the weeds emergence. When the doses required for 80% effective control were considered, the results showed that for indaziflam, the filter cake negatively affected crabgrass control. In contrast, vinasse had a positive effect on morning glory control by saflufenacil. For sulfentrazone, the filter cake had a negative effect, requiring twice the dose used on the treatment without byproduct for effective morning glory control. Relative to assay 2, the vinasse addition affected the emergence of morning glory but not of crabgrass; however, the filter cake increased the weed biomass accumulation. Vinasse and filter cake byproducts can negatively or positively affect the performance of pre-emergence herbicides, according to the active ingredient used. However, these effects occur at doses below those recommended for the herbicides. Byproducts can affect the emergence and the weed biomass accumulation.

Changes in the Microbial Metabolism of Agricultural Tropical Soils Amended with Sugarcane Vinasses

Sugarcane vinasse is a liquid waste derived from ethanol production. In Brazil, large amounts of this waste are applied to soil as fertigation. In general, this management seems to be beneficial for soil fertility and for some biological parameters, though the published information about the effects of sugarcane vinasse on the soil biota is controversial and the results may vary according to the vinasses’ composition. In this study, we assessed the effects of different sugarcane vinasses on microbial growth and activity indicators to verify their influence on soil microbial metabolism. For this purpose, we used two vinasses from different distillery plants (VA and VB) and a vinasse from a laboratory production (VC). Increasing concentrations of these vinasses were amended on two tropical Oxisols, with 33.6% (RL) and 17.6% (RYL) of clay, in a microcosm experiment with sugarcane plants. Ten, 30 and 60 days after application, we assessed the effects of the vinasses on soil microbial biomass carbon (MBC), basal soil respiration (C–CO2), the metabolic quotient (qCO2) and dehydrogenase activity of the soils. We found an increase in MBC, C–CO2, qCO2, as well as in dehydrogenase activity with increasing vinasse concentrations in both soils, when compared to the control. These changes were attributed mainly to the addition of carbon sources (C) of the vinasses to the soils, which improves the general biological activity.

Valorization of Sugar-Ethanol Industry Waste Vinasse for Increased Second-Generation Ethanol Production Using Spathaspora passalidarum Yeast Strains

In this study, sugarcane bagasse hydrolysate supplemented with different proportions of sugar-ethanol industrial waste (vinasse) was used to optimize fermentative ethanol production using two Spathaspora passalidarum yeast strains isolated from decaying wood in Amazonian biome. The bagasse samples were pretreated chemically and enzymatically before using a binary factorial experimental design. The factorial design was carried out in two stages; in the first, a 24 factorial design was done to assess the effects of pretreated sugarcane bagasse hydrolysate and vinasse, ammonium sulfate concentration, yeast biomass concentration, and two different strains of yeast, S. passalidarum; in the second stage, a 23 factorial design was done to provide a more detailed analysis of the effects of vinasse supplementation on the fermentation process—this time, by modifying the ratio of sugarcane bagasse hydrolysate and vinasse and, more significantly, the same factor—biomass concentration. The results showed that the most significant factors for increasing bioethanol production in the 24 factorial design proved to be the following: inoculum and hydrolyzed bagasse supplementation with vinasse (the optimal being 75:25), followed by yeast concentration (optimal at 14% w/v cell wet weight) and then the type of strain used (S. passalidarum UFMG-HMD-14.1). The use of only hydrolyzed bagasse without vinasse (23 factorial design) had no significant influence on the results, nor did varying the concentration of nitrogen. This increase in ethanol production, which allows the same amount of ethanol productivity through a reduction in the carbon source, suggests it can lead to an improved final use for vinasse.

The potential application of an autochthonous fungus from the northwest of Argentina for treatment of sugarcane vinasse.

Vinasse is a waste material from distillery industries, which causes major environmental problems around the world. Argentina alone produces about 4 billion liters of vinasse annually; consequently, diverse biological eco-friendly treatments are evaluated for their ability to reduce the detrimental effects. The present study reports on the degradation of a 50% (v/v) local vinasse sample by an autochthonous fungus identified as Aspergillus sp. V1. The Bioprocess was conducted for 15 d at 30 °C after inoculation of spores at an end concentration of 1 × 106 CFU/mL. Effluent neutralization was detected after 6 d of treatment, with maximum COD and BOD removal after 12 d (49% and 59%, respectively). Effects of vinasse before and after treatment were predicted using Caco-2 cells and Triticum aestivum L. (wheat) seeds as toxicological indicators. Only 13% viability was observed for Caco-2 cells exposed to untreated vinasse, but this percentage increased more than 3-fold for cells exposed to the treated effluent. While vinasse without treatment completely inhibited germination of seeds, exposure to treated effluent demonstrated a germination percentage of 60%. The present study highlights the use of a dual-purpose biotechnological process that aimed at reducing the detrimental effects of vinasse, enhancing its quality for agricultural practices.

Effects of vinasse and lithothanmium application on the initial growth of sugar cane (Saccharum sp. cv. RB 86-7515) irrigated and not irrigated

La investigación se llevó a cabo en la Escuela de Agronomía de la Universidade Federal de Goiás, Brasil. El delineamiento estadístico fue en un diseño completamente aleatorio con tres repeticiones, en esquema factorial (5 x 5 x 2). Las plantas fueron cultivadas en contenedores de plástico de 200 litros. Los tratamientos correspondieron a cinco dosis de vinaza (0, 165, 330, 495 e 660 m3.h-1) y cinco dosis de lithothanmium (0, 100, 200, 300 e 400 kg.ha-1) en dos ambientes: irrigado y no irrigado. El sistema de irrigación utilizado fue por goteo con emisores de 4 L.h-1. La aplicación de los tratamientos de fertilización, fueron divididas de acuerdo con la marcha de absorción de nutrientes por las plantas de caña de azúcar. Se evaluaron número de brotes (cañas), altura de plantas, índice de área foliar y diámetro del cormo a lo largo de diferentes etapas fenológicas del cultivo. Los tratamientos aplicados provocaron efectos significativos sobre los parámetros de crecimiento del cultivo, siendo las plantas irrigadas y fertilizadas con 196 kg.ha-1 de lithothanmium y 330 m3.ha-1 de vinaza, las que exhibieron los mejores resultados.

Methane emissions from sugarcane vinasse storage and transportation systems: Comparison between open channels and tanks

Over the last few years the brazilian sugarcane sector has produced an average of 23.5 million liters of ethanol annually. This scale of production generates large amounts of vinasse, which depending on the manner that is disposed, can result significant greenhouse gas emissions. This study aimed to quantify the methane (CH4) emissions associated with the two most widespread systems of vinasse storage and transportation used in Brazil; open channel and those comprising of tanks and pipes. Additionally, a laboratory incubation study was performed with the aim of isolating the effects of vinasse, sediment and the interaction between these factors on CH4 emissions. We observed significant differences in CH4 emissions between the sampling points along the channels during both years of evaluation (2012–2013). In the channel system, around 80% of CH4 emissions were recorded from uncoated sections. Overall, the average CH4 emission intensity was 1.36 kg CO2eq m−3 of vinasse transported in open channels, which was 620 times higher than vinasse transported through a system of tanks and closed pipes. The laboratory incubation corroborated field results, suggesting that vinasse alone does not contribute significant emissions of CH4. Higher CH4 emissions were observed when vinasse and sediment were incubated together. In summary, our findings demonstrate that CH4 emissions originate through the anaerobic decomposition of organic material deposited on the bottom of channels and tanks. The adoption of coated channels as a substitute to uncoated channels offers the potential for an effective and affordable means of reducing CH4 emissions. Ultimately, the modernization of vinasse storage and transportation systems through the adoption of tank and closed pipe systems will provide an effective strategy for mitigating CH4 emissions generated during the disposal phase of the sugarcane ethanol production process.

Potential effects of vinasse as a soil amendment to control runoff and soil loss

Abstract. Application of organic materials are well known as environmental practices in soil restoration, preserving soil organic matter and recovering degraded soils of arid and semiarid lands. Therefore, the present research focused on evaluating the effectiveness of vinasse, a byproduct mainly of the sugar-ethanol industry, on soil conservation under simulated rainfall. Vinasse can be recycled as a soil amendment due to its organic matter content. Accordingly, the laboratory experiments were conducted by using 0.25 m2 experimental plots at 20 % slope and rainfall intensity of 72 mm h−1 with 0.5 h duration. The effect of vinasse was investigated on runoff and soil loss control. Experiments were set up as a control (with no amendment) and three treated plots with doses of 0.5, 1, and 1.5 L m−2 of vinasse subjected to simulated rainfall. Laboratory results indicated that vinasse at different levels could not significantly (P &gt; 0.05) decrease the runoff amount and soil loss rate in the study plots compared to untreated plots. The average amounts of minimum runoff volume and soil loss were about 3985 mL and 46 g for the study plot at a 1 L m−2 level of vinasse application.

Vinasse and Biochar Effects on Germination and Growth of Palmer Amaranth (Amaranthus palmeri), Sicklepod (Senna obtusifolia), and Southern Crabgrass (Digitaria ciliaris)

Vinasse and biochar are by-products of biofuel production that can be used as sources of nutrients to crops or soil amendments to improve soil quality. Despite the recent interest in biochar and vinasse effects on soil properties, little is known about their effect on weed communities. We hypothesized that the addition of biochar and vinasse to the soil could affect weed seed germination and growth, and that different weed species would show different responses to these soil amendments. Therefore, the objectives of this study were to determine the effects of vinasse and biochar on the germination and growth of Palmer amaranth, sicklepod, and southern crabgrass. The study was conducted under laboratory and growth chamber conditions. Treatments consisted of four levels of vinasse (0, 10, 20, and 40 L m−2) and biochar (0, 0.5, 2.5, and 12.5 kg m−2) applied to a sandy loam soil. Biochar at 0.5 and 2.5 kg m−2increased germination of Palmer amaranth but had no effect on sicklepod and southern crabgrass. Vinasse reduced germination of all species. However, sicklepod germination was less affected by vinasse at 10 and 20 L m−2than the other two species. Vinasse at 40 L m−2decreased Palmer amaranth, southern crabgrass and sicklepod germination 57, 26 and 87%, respectively. Biochar had no consistent effect on the vegetative growth of the species studied. Vinasse at 10 L m−2stimulated growth of sicklepod and southern crabgrass compared to the nontreated control. Our results suggested that vinasse used as a soil amendment could affect weed community structure by decreasing germination of susceptible species, but plants and weed species that can get established in vinasse amended soils might show higher growth rates.

Effects of Vinasse and Press Mud Application on the Biological Properties of Soils and Productivity of Sugarcane

The present study has been conducted to investigate the effects of vinasse and press mud (PM) (sugar industry by-products) applications on sugarcane soil microbial population, its enzyme activities and biomass carbon and nitrogen in order to work out its potential to be used as bio-friendly fertilizer. The treatments were compared with traditional chemical fertilizer (CF) applications. Vinasse and PM amended soils were found to have slightly lower pH and higher total N and C content, however, the difference was insignificant with CF amended soils. Both the treatments increased sugarcane yield compared to chemical fertilizer, but this increase was not significant in PM amended soils. The populations of fungi, bacteria and actinomycetes increased in vinasse and PM amended soils. This increase in former one was significant in PM amended soils only, and that of the latter in vinasse amended soil. The biomass C and N contents were also higher in both the treatments, however, only the former one had significant difference with CF. Amongst the soil enzymes, the activities of cellulase, phosphatase and aminopeptidase were significantly higher in PM treatment while these were at par in vinasse and CF treatments. These results showed a potential possibility of substituting chemical fertilizers with vinasse and press mud which besides improving soil health and enhancing sugarcane productivity, can also solve the problem of their disposal in free environment.

Clastogenicity of landfarming soil treated with sugar cane vinasse

The addition of nutrients and/or soil bulking agents is used in bioremediation to increase microbial activity in contaminated soils. For this purpose, some studies have assessed the effectiveness of vinasse in the bioremediation of soils contaminated with petroleum waste. The present study was aimed at investigating the clastogenic/aneugenic potential of landfarming soil from a petroleum refinery before and after addition of sugar cane vinasse using the Allium cepa bioassay. Our results show that the addition of sugar cane vinasse to landfarming soil potentiates the clastogenic effects of the latter probably due the release of metals that were previously adsorbed into the organic matter. These metals may have interacted synergistically with petroleum hydrocarbons present in the landfarming soil treated with sugar cane vinasse. We recommend further tests to monitor the effects of sugar cane vinasse on soils contaminated with organic wastes.

Cargas superficiais da fração argila de solos influenciadas pela vinhaça e fósforo

Effects of vinasse, P sorption and the interaction vinasse-phosphorus on zeta potential and point of zero charge (PZC) as well as the effects of vinasse on P sorption on clay-fraction samples from two soils were evaluated. The vinasse and P sorption influenced the surface charge of clay fraction of both soils. Sorption of P increased negative charges from soil particles reducing PZC. These effects were more pronounced when clay fraction was previously treated with vinasse. Vinasse treatment reduced P sorption, probably due to coating of P-adsorption sites and by enhancing the negative charges.

Lead sorption and leaching from an Inceptisol sample amended with sugarcane vinasse

Vinasse is produced at high amounts by the ethanol and sugarcane spirits industries. Although the effects of vinasse on soil attributes are well elucidated, little is known about its effects on sorption and leaching of lead (Pb) from soils. This work evaluated the Pb sorption and leaching from disturbed topsoil samples (0-20 cm) of an Inceptisol, under the influence of sugarcane vinasse. Pb sorption was evaluated by batch sorption method, using air-dried samples (&lt; 2 mm) treated with pure (100%), and diluted (20%, and 50%) vinasse. The amended soil samples were further reacted with 0.05; 0.10; 0.25; 0.50, and 0.75 mmol L-1 of Pb. To measure the Pb leached, soil columns were packed in PVC tubes, 12-cm long with 4-cm internal diameter filled with 200 g of treated soil. The vinasse doses applied over the columns corresponded to 0 (control), 150 and 300 m³ ha-1. Seven days later, 5 mL of a Pb solution (100 mmol L-1) was applied on the columns; they were successively leached and Pb was measured in the leachates. The vinasse increased the maximum sorption capacity and binding energy of Pb with the soil when at equilibrium conditions. However, at non-equilibrium conditions, the vinasse enhanced the Pb leaching. From these results, it is advised that special attention must be given to Pb contaminated areas where vinasse is applied.

Efeito da queima da palhada da cana-de-açúcar e de aplicações de vinhaça e adubo nitrogenado em características tecnológicas da cultura

As práticas da queima, aplicação de vinhaça e fertilizante nitrogenado são comuns na cultura de cana-de-açúcar. No entanto, estudos de longa duração são pouco encontrados na literatura. Neste trabalho, realizado na Usina Cruangi, Timbaúba, PE, transição entre a Zona da Mata e o Agreste daquele Estado, objetivou-se avaliar o efeito da aplicação de N (80 kg ha-1 na forma de uréia), da vinhaça (80 m³ ha-1) e da queima (com ou sem queima) da palhada antes do corte, entre 1983 e 1999, em características tecnológicas da cultura de cana-de-açúcar. O delineamento experimental foi o de blocos ao acaso, em esquema fatorial completo 2 x 2 x 2, e quatro repetições. O experimento teve duas fases: a primeira, de 1983-1992, e a segunda, de 1992-1999. A aplicação de N afetou as características tecnológicas da cana-de-açúcar; no entanto, o ganho de produtividade de colmos proporcionado por esta prática favoreceu a produção de açúcar e compensou tais efeitos. A aplicação de vinhaça e a manutenção da palhada no sistema não afetaram, de forma consistente, as características tecnológicas da cultura de cana-de-açúcar, embora tenham influenciado, de forma positiva, a produção de açúcar, de acordo com o ganho de produtividade.

Long-term Effects of Pre-harvest Burning and Nitrogen and Vinasse Applications on Yield of Sugar Cane and Soil Carbon and Nitrogen Stocks on a Plantation in Pernambuco, N.E. Brazil

Since the 1970s the area under sugarcane in Brazil has increased from 2 million to over 5 million ha (M ha), and it is expected to pass the 7 M ha mark in 2007. More than half of the cane is harvested to produce bioethanol as a fuel for light vehicles. The distilleries produce approximately 13 L of distillery waste (vinasse) for each litre of ethanol produced. In the 1980s there was considerable concern over the long-term effects of the disposal of this material (containing about 1% carbon and high in K) on cane yields if it was applied to the field. At the same time there was a growing movement to abandon the practice of pre-harvest burning and some research was showing that some Brazilian varieties of sugar cane were able to obtain significant contributions of N from plant-associated biological nitrogen fixation (BNF). For these reasons an experiment was installed on a cane plantation in the state of Pernambuco, NE Brazil to investigate the long-term effects of vinasse and N fertiliser additions and the practice of pre-harvest burning on crop and sugar yield, soil fertility parameters, N balance and soil C stocks. The results showed that over a 16-year period, trash conservation (abandonment of burning) increased cane yields by 25% from a mean of 46 to 58 Mg ha−1. Vinasse applications (80 m3 ha−1 crop−1) increased mean cane and sugar yield by 12 to 13% and the application of 80 kg N ha−1 as urea increased cane yields by 9%, but total sugar yield by less than 6% (from 7.0 to 7.4 Mg ha−1 crop−1). The total N balance for the soil/plant system when only the surface 20 cm of the soil was considered was positive in plots where no N fertiliser was added. However, the data indicated that during the 16 years of the study considerable quantities of soil organic matter were accumulated below 20 cm depth such that the N balance considering the soil to 60 cm depth was strongly positive, except where N fertiliser was added. The data indicated that there were considerable BNF inputs to the system, which was consistent with its low response to N fertiliser and low N fertiliser-use-efficiency. There were no significant effects of vinasse or urea addition, or trash conservation on soil C stocks, although the higher yields proportioned by trash conservation had potentially significant benefits for increased mitigation of CO2 emissions where the main use of the cane was for bioethanol production.

Degradação e sorção de ametrina em dois solos com aplicação de vinhaça

Este trabalho teve o objetivo de avaliar os efeitos da adição de vinhaça nos processos de degradação e sorção do herbicida ametrina em solos das classes Terra Roxa Estruturada (TR) e Latossolo Vermelho-Amarelo (LV). No estudo da degradação foi instalado um experimento, em delineamento inteiramente casualizado arranjado em fatorial 2 (solos) x 3 (doses de vinhaça: 0, 100 e 200 m³ ha-1), que foi conduzido por 120 dias. A mineralização foi avaliada por radiorrespirometria. Após os 120 dias, o herbicida foi extraído do solo e detectado em "radio-scanner". Paralelamente, foi conduzido um ensaio para avaliação do efeito das doses de vinhaça juntamente com a ametrina na atividade microbiana, pH e C orgânico do solo. O experimento de sorção foi realizado com os mesmos tratamentos empregados no estudo de degradação, utilizando-se cinco concentrações do herbicida. A degradação da ametrina foi maior na presença de 100 m³ ha-1 de vinhaça. A adição do resíduo contribuiu para o aumento da atividade microbiana e do pH. A ametrina foi pouco sorvida nos dois solos, não apresentando influência da adição da vinhaça.
