Elucidating the molecular mechanisms in phytohormones-induced alleviation of postharvest physiological deterioration in cassava tuberous roots

Cassava is a staple food crop in tropical regions, serving as a significant source of carbohydrates. However, rapid postharvest physiological deterioration (PPD) significantly limits the shelf life and utilization of cassava. Despite its importance, the overlapping molecular mechanisms underlying phytohormones-induced PPD alleviation in cassava tuberous roots remain unknown. In this study, the phytohormones ethephon (ET), gibberellic acid (GA), and methyl jasmonate (MeJA) were applied to cassava tuberous roots after harvest. These treatments led to significantly reduced H2O2 accumulation and alleviation of PPD. Transcriptomic analysis revealed shared functions, including transcriptional regulation and oxidoreductase activity, among differentially expressed genes (DEGs) affected by ET, GA, or MeJA. A total of 305 genes encoding antioxidant enzymes were systematically identified, with 151 responsive to phytohormone treatments across ten families. Notably, the expression of 10 Glutathione S-transferase (GST) genes was induced by all three phytohormone treatments, while their expression was suppressed in the absence of phytohormones during PPD. By using co-expression network analysis, DNA-binding motif analysis, and experimental validation using yeast one-hybrid and dual-luciferase assays, a regulatory network involving MeMYB102 and MeZAT11 transcription factors (TFs) that directly promote the expression of MeGST42, MeGST43, MeGST44, and MeGST46 was established. Overall, this study enhances the understanding of the overlapping molecular mechanisms underlying phytohormones-induced alleviation of PPD in cassava, thereby providing genetic resources for developing PPD-resistant cassava.

Varietal screening for identification of postharvest physiological deterioration tolerance in storage roots of cassava

ABSTRACT Postharvest physiological deterioration (PPD) is a constraint in cassava (Manihot esculenta Crantz) and a threat to effective utilization of cassava roots. This study determined the magnitude of variability for PPD tolerance among cassava genotypes and identified new sources of tolerance to PPD. Seventy-six cassava genotypes were evaluated for PPD tolerance at postharvest evaluation intervals of 3, 5, 7, 10, 15, or 20 days after harvest. Repeated measure analysis indicated that differences for PPD reliably depend on time in conjunction with genotype and years. The genotypes were categorized into nine classes using rank-sum statistics involving standardized mean range, PPD, and PPD per day. Nineteen genotypes were tolerant and three were free of symptoms up to 20 days postharvest. Released varieties had tolerance to PPD compared to local varieties and pre-breeding lines. The PPD symptoms were mostly found in peripheral regions and in proximal and distal ends rather than in the mid-region of the root. The presence of the root neck reduced deterioration. Root length, weight, and dry matter content were positively correlated with PPD. The new sources of tolerance may improve the adoption and utilization of cassava.

Effects of Processing Methods and Conditioning Temperatures on the Cassava Starch Digestibility and Growth Performance of Broilers.

As an important food crop, cassava is rich in nutrients and high in starch content and is widely used in the production of industrial raw materials. However, the utilization value of cassava is limited due to the reduction of planting area and the existence of anti-nutritional factors. Therefore, we evaluated in vitro cassava starch digestibility and in vivo growth performance of broilers in a 3 × 3 factorial arrangement of treatments using three processing methods (mechanical crushing (MC), steam conditioning (SC), and puffing conditioning (PU)) and three conditioning temperatures (60, 75, and 90 °C) to screen for the optimal processing method and conditioning temperature to improve the utilization of cassava. In the in vitro cassava starch digestion study, the digestibility and digestion rate (p < 0.01) were higher at conditioned 90 °C than that at 60 or 75 °C, and PU was higher than SC and MC (p < 0.01) (0.25-2 h). The amylose content and amylose/amylopectin at conditioned 60 °C or PU were lower (p < 0.01) than that of 75 or 90 °C or SC, whereas the opposite was true for amylopectin content (p < 0.01). The resistant starch content of SC or PU was lower (p < 0.01) than MC. In the in vivo study, broilers fed diets conditioned at 60 °C or SC had a lower (p < 0.05) feed-to-gain ratio than those fed diets conditioned at 90 °C or PU diets. The ileum apparent digestibility of starch and AME were higher (p < 0.05) for broilers fed SC diets than for those fed MC diets. These results indicate that cassava starch promoted starch digestion rate by reducing amylose content and amylose/amylose under PU combined with a conditioning temperature of 60 °C, ileum digestibility of starch in broilers fed SC diets was higher than MC diets regardless of conditioning temperature, and SC diets increased AME and decreased F/G to promote growth performance of broilers.

Utilization of cassava (Manihot esculenta) as alternative local food source supporting food diversification in North Maluku

Cassava is a food commodity widely cultivated and developed in North Maluku based on local wisdom, which is essential in supporting food security. This study aims to conduct an inventory and determine the use of cassava as an alternative food source in North Maluku. Inventory and characterization of activities carried out from March to December 2019. The method used was descriptive exploration with surveys, field observations, and interviews. The inventory results showed that North Maluku has the potential of cassava as a source of carbohydrates and alternative food to reduce dependence on people's rice consumption. A large amount of cassava production supports the possibility of providing local non-rice food sources in North Maluku. In addition, there were 13 local cassava accessions identified. Processed cassava into other food products had added value and encouraged increased consumption of this commodity as a non-rice local food commodity of strategic value. The government plays an essential role in the food diversification program to increase public awareness of consuming non-rice local food such as cassava. Kasbi sago is one of the typically processed cassava products and is widely consumed by the people of North Maluku.

Identification of antinutritional, antioxidant, and antimicrobial activity of plants that cause livestock poisoning in Bojonegoro Regency, Indonesia.

The utilization of cassava leaves and peels, ceara rubber leaves, sweet potato leaves, Chinese Albizia leaves, and lophatheri leaves from Bojonegoro Regency has led to the poisoning of livestock due to antinutritional factors. Nevertheless, the plants are known to have bioactive components and potential antioxidant and antibacterial activity if appropriately processed. This study aimed to determine the antinutritional compounds as well as the antioxidant and antibacterial potential of these plants responsible for livestock poisoning in the Bojonegoro Regency. Extraction was performed by the maceration method using 70% (v/v) ethanol solvent. The samples were analyzed qualitatively to determine the presence of tannins, alkaloids, oxalates, cardiac glycosides, and cyanogenic glycosides. The antioxidant activity was determined using the 1,1-diphenyl-2-picrylhydrazyl method, while the antimicrobial activity was assessed by different testing concentrations (125, 250, and 500 mg/mL) against Staphylococcus epidermidis, Staphylococcus aureus, and Escherichia coli. The ethanolic extract of the plants was found to contain antinutritional tannins, alkaloids, cardiac glycosides, and cyanogenic glycosides suspected of causing livestock poisoning. Despite the presence of these antinutrients, all extracts also had antioxidant and antibacterial potential. Cassava peels and sweet potato leaves had the highest antioxidant activity, whereas Chinese Albizia leaves had the most potent antibacterial activity. Cassava leaves and peels, ceara rubber leaves, sweet potato leaves, Chinese Albizia leaves, and lophatheri leaves obtained from Bojonegoro Regency and used as agricultural waste contain antinutritional factors but also possess potentially effective antioxidant and antimicrobial components.

BIOETHANOL POTENTIAL FROM WHOLE PARTS OF CASSAVA PLANT IN INDONESIA

Cassava is a promising bioethanol feedstock as all parts of cassava plant including its tuber, stem, leaves, along with processing waste such as peel and bagasse can be used in bioethanol production. However, bioethanol potential from the whole parts of cassava plant is not yet summarized. This research reviewed and calculated the average bioethanol yield from each part of the cassava plant, and calculated bioethanol potential from the whole parts of cassava plant, especially in Indonesia. Fresh cassava tuber, fresh stem, fresh leaves, fresh peel, and dry bagasse are found to have average bioethanol yield of 180 L/ton, 155 L/ton, 75 L/ton, 160 L/ton, and 390 L/ton, respectively. If the whole cassava plant along with its processing waste is utilized for bioethanol production, cassava plants that produce a ton of fresh cassava tuber can yield 400 L bioethanol. With a scenario of total area harvested 700,000 ha and cassava productivity of 22.5 tonnes/ha/year, bioethanol potential from whole cassava plant and its processing waste in Indonesia is 6.3 billion L/year. However, using all the cassava plant for bioethanol production is impractical, considering other utilization of cassava. The bioethanol potential from whole parts of cassava plant after considering other use of plant becomes 2.9 billion L/year. Even when the cassava tuber is used for other utilization, bioethanol from unused cassava stem, leaves, peel, and bagasse is still significant and worth considering.

Effective continuous acetone\u2013butanol\u2013ethanol production with full utilization of cassava by immobilized symbiotic TSH06

BackgroundButanol production by fermentation has recently attracted increasingly more attention because of its mild reaction conditions and environmentally friendly properties. However, traditional feedstocks, such as corn, are food supplies for human beings and are expensive and not suitable for butanol production at a large scale. In this study, acetone, butanol, and ethanol (ABE) fermentation with non-pretreated cassava using a symbiotic TSH06 was investigated.ResultsIn batch fermentation, the butanol concentration of 11.6 g/L was obtained with a productivity of 0.16 g/L/h, which was similar to that obtained from glucose system. A full utilization system of cassava was constructed to improve the fermentation performance, cassava flour was used as the substrate and cassava peel residue was used as the immobilization carrier. ABE fermentation with immobilized cells resulted in total ABE and butanol concentrations of 20 g/L and 13.3 g/L, which were 13.6% and 14.7% higher, respectively, than those of free cells. To further improve the solvent productivity, continuous fermentation was conducted with immobilized cells. In single-stage continuous fermentation, the concentrations of total ABE and butanol reached 9.3 g/L and 6.3 g/L with ABE and butanol productivities of 1.86 g/L/h and 1.26 g/L/h, respectively. In addition, both of the high product concentration and high solvent productivity were achieved in a three-stage continuous fermentation. The ABE productivity and concentration was 1.12 g/L/h and 16.8 g/L, respectively.ConclusionsThe results indicate that TSH06 could produce solvents from cassava effectively. This study shows that ABE fermentation with cassava as a substrate could be an efficient and economical method of butanol production.

Development of Instant Microbial Starter for Production of Fermented Cassava Flour: Effect of Vacuum Drying Temperature, Carrier Media, and Storage Temperature

Cassava is an important crop for tropical countries such as Nigeria, Brazil, Thailand, and Indonesia. The potential utilization of cassava in the food industry can be enhanced by processing cassava into fermented cassava flour (fercaf), which has been shown to have a neutral color and aroma as well as low cyanogenic content. The use of specific microbial starter in the cassava chip fermentation for fercaf production will direct the fermentation process, maintaining a high quality of the produced flour. Thereby, the availability of an easy-to-use microbial starter is important for the production of fermented cassava flour. The aim of this study was to evaluate vacuum drying methods in the preparation of microbial starter for fermented cassava flour production. In particular, the effects of carrier media, drying and storage temperature on cell viability in dry starter were tested. The results showed that different methods should be applied to different microbial species. Bacillus subtilis and Aspergillus Oryza should be prepared using fercaf as the carrier media at a drying temperature of 55 °C, whereas Lactobacillus plantarum starter should be prepared using skim milk as the carrier media at a drying temperatur of 40°C. Apart from B. subtilis, the starters should be stored in a refrigerator.

Effect of Lime Pretreatment on Microstructure of Cassava Stalk Fibers and Growth of Aspergillus niger

Cassava stalk can be converted into sugar-based product by using microorganism. Unfortunately, lignin act as a barrier of optimal bioconversion. Cassava stalk needs pretreatment process for removing this barrier. The effect of lime pretreatment on microstructure of cassava stalk fibers and the growth of Aspergillus niger FNCC 6114 were observed in this research. The cassava stalks were reduced into 0.147- 0.297 mm size and pretreated with 1 % Ca(OH)2. Lime pretreated and unpretreated cassava stalk was used as solid medium for Aspegillus niger FNCC 6114. The effect of pretreatment method on fibers microstructure of cassava stalk was evaluated through SEM micrograph. The growth and metabolism activities of Aspergillus niger FNCC 6114 were monitored through SEM micrograph of media after fermentation. The other parameters examined were changes in glucosamine, reducing sugar levels, and spores’ quantity. Lime pretreatment altered microstructure of cassava stalk fibers. However, cassava stalk without lime pretreatment gave better growth of Aspergillus niger FNCC 6144 based on metabolism activities parameters. Cassava stalks is suitable as media for Aspergillus niger FNCC 6144 through solid state fermentation. For better growth of Aspergillus niger FNCC 6144 fine-sized cassava stalk should not be lime pretreated. The results of this study provide information about the pretreatment of cassava stems which was effective in supporting the growth of Aspergillus niger. Enhancements the utilization of cassava stems by using fungi, for example Aspergillus niger can overcome the accumulation of organic waste that can interfere with environmental sustainability.

Economic Evaluation of the Production Ethanol from Cassava Roots

The purpose of this study was to evaluate the prospective production of ethanol from cassava in Indonesia. The study was conducted in two parameters, engineering perspectives and economic evaluation that involves several economic parameters (e.g. gross profit margin, internal rate return, payback period, cumulative net present value, breakeven point, and profitability index on sales to investment). The engineering analysis results the potentiality of the ethanol production from cassava roots, using fermentation followed with distillation processes. This analysis was supported by the excellent obtainment of economic evaluation of GPM, BEP, PBP, and other analysis. However, the good profitability results were obtained only in the specific condition, in which the minimum requirement for the amount of cassava must be passed. Since cassava is highly abundant in tropical countries, the present analysis is important for giving knowledge for the further potential utilization of cassava.

Chemical Composition of Major Cassava Varieties in Uganda, Targeted for Industrialisation

Uganda is one of the major cassava producing countries in the world. Currently, utilization of cassava is limited to semi-processed products through the informal sector. Cassava has technological potential as a raw material for agro-industrial products, such as flours for baked products, animal feeds and starch. The aim of this study was to investigate the chemical composition of five major cassava varieties grown in Nebbi distict (Uganda), to assess their potential as industrial raw materials. Analysis of the chemical composition of local (Nyamatia and Nyarukeca) and improved (NASE 3, NASE 14, and NASE 19) cassava varieties was carried out using standard methods. Results showed significant (p &lt; 0.05) differences between the varieties indicating high levels of starch, calcium, magnesium, cyanonenic glucosides and phytates. The cassava varieties contain low levels of protein, lipids and minerals with respect to recommended daily intake of these nutrients. Moisture contents ranged from 5.43 for Nyamatia to 10.87 for NASE 19; ash from 1.05 for Nyamatia to 2.39 for NASE 14; crude fiber from 1.06 for Nyamatia to 1.18 for NASE 19; crude protein from 0.74 for Nyarukeca to 1.51 for NASE 14; crude lipid from 0.39 for Nyamatia to 0.63 for NASE 19; and starch contents from 66.72 for NASE 19 to 84.42 for NASE 3. The mineral contents (mg/kg): calcium ranged from 13.15 for Nyamatia to 16.56 for NASE 3; iron ranged from 0.002 for Nyarukeca to 0.01 for NASE 19; zinc ranged from 0.56 for Nyamatia to 0.87 for NASE 3; magnesium ranged from 3.58 for NASE 19 to 3.88 for Nyarukeca; and copper ranged from 0.002 for Nyamatia to 0.14 for NASE 3. The contents of anti-nutrients (mg/kg): cyanogenic glucosides ranged from 30 in NASE 3 and NASE 19 to 800 in Nyamatia; phytates ranged from 661.33 in Nyarukeca to 984.64 in NASE 3; oxalates ranged from 90.6 in Nyarukeca to 227.8 in NASE 3; and tannin ranged from 0.18 in Nyarukeca to 0.33 in NASE 3. Based on the chemical composition results, all the cassava varieties studied contain higher levels of cyanogenic glucosides than recommended by Ugandan and East African Standards, making them unsafe for direct utilization as food and food raw materials for industries at levels beyond 30% in food formulations. The high starch levels in all the cassava varieties make them valuable raw materials for starch and starch-related industries.
