Isolation of Rhizobium from Moisture Stress Imposed Groundnut Nodules

Groundnut is an important oil seed crop accounts for a less than half of the major oilseeds produced in the country. Oil content of Groundnut varies from 44 % to 50 % depending upon the varieties and agronomic practices. It is also called as ‘king of oil seeds’ More than 85 % of the crop Is grown under rainfed conditions in low fertile soils. Rhizobium is a well-known symbiotic nitrogen fixing bacteria. Inoculation of Rhizobium improves plant growth, pod kernel and Oil yield. Rhizobium species help in improving root nodulation and nitrogen fixation, enhancing plant growth and yield of leguminous plants including groundnut under moisture stress conditions. Hence the present study is to isolate Rhizobium species from groundnut nodules by following method given by Vincent (1970) after growing them on Yeast Mannitol Agar Media morphological characteristics were studied, which can be further used for improving nodulation efficiency and plant growth promotion under moisture stress conditions.

Effect of transglutaminase on the structure, properties and oil absorption of wheat flour

The structure, properties, as well as the oil absorption characteristics of wheat flour (WF) treated with varying concentrations of transglutaminase (TG) (0 U/g ∼ 50 U/g) were characterized. The content of free amino groups in WF modified by TG (TG-WF) decreased and protein aggregated. The isopeptide bonds and disulfide bonds played important roles in protein crosslinking. The thermal stability, the peak viscosity after gelatinization and protein secondary structure stability of TG-WF were improved. In addition, the oil absorption and surface oil content of TG-WF after frying were reduced. TG enhanced the protein-protein interactions in WF, so that protein played barrier roles in the process of high-temperature frying, protecting the starch particles covered by them from the infiltration of oil, thus reducing the oil absorption of TG-WF during frying. Among them, the oil content of TG-WF-30 U/g after frying was the lowest, which decreased by 10.73 % compared with the control group.

Ecological study of false saffron in Russia, Kazakhstan and Tajikistan to ensure food security

Safflower oilseed is a crop native to Egypt and India with arid climates. Global warming in the world requires an alternative approach to well-known oilseeds (sunflower, rapeseed). Many years of research have been carried out to study the culture of safflower oilseed in contrasting natural conditions Russia, Southern Kazakhstan, and Tajikistan. The goal was to study the biological characteristics, productivity, accumulation of oil content, and the manifestation of the main disease in arid conditions and to create a variety with adaptive potential for a specific region. Based on the research results, new varieties of safflower oilseed Krasa Stupinskaya (Russia), Akmai, Nurlan, Iirkas, and Moldir-2008 (Kazakhstan), Shifo (Tajikistan) were created and recommended for sustainable farming in the above regions. In terms of the accumulation of oil and fatty acid composition in the seeds, the Krasa Stupinskaya variety from the Central region of the Russian Federation is at the level of southern varieties from Kazakhstan and Tajikistan. In a warming climate, the above varieties will ensure food security in their countries due to stable yields, sufficient accumulation of oil content in seeds and disease resistance.

Applied AMT machine learning and multi-objective optimization for enhanced performance and reduced environmental impact of sunflower oil biodiesel in compression ignition engine

Biodiesel has emerged as a compelling substitute for conventional diesel fuel, providing a sustainable and eco-friendly choice for fueling compression ignition engines. This comprehensive study investigates the influence of biodiesel, specifically derived from sunflower oil, through the esterification method, on crucial engine performance parameters and environmental effects. The study examines the impact of varying engine torque on the performance of a single-cylinder, four-stroke compression ignition engine, encompassing parameters such as brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC), as well as exhaust emissions, including unburned hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx). Four distinct biodiesel blends (B10, B20, B30, B40) with varying sunflower oil content are systematically compared to pure diesel (B0). The engine operates at a consistent speed of 1700 rpm, while the torque undergoes controlled adjustments from 0 to 10 Nm. Subsequently, this study explores the application of an alternating model tree (AMT) machine learning algorithm to establish relationships between independent factors, specifically torque and biodiesel volume (%vol), and dependent variables, including BTE, BSFC, CO, and NOx in a combustion engine. Additionally, the study employs a multi-objective ameliorative whale optimization algorithm (AWOA) to optimize the model's output. The objective is to identify optimal values for torque and%vol that maximize engine performance (BTE) while minimizing engine emissions (CO and NOx) and reducing fuel consumption (BSFC). The optimization process yields noteworthy results, with AWOA achieving peak BTE at 29.714 %, BSFC at 0.262 kg.kWh-1, and NOx emissions at 992 ppm at torque 7.3 N.m and 13% vol. In contrast, particle swarm optimization (PSO) secured the minimum CO level at 0.123 %, with torque set at 7.6 N.m and 26% vol. The AMT models demonstrate high prediction accuracy, with coefficient of determination (R2) values exceeding 0.98.

Inheritance and QTL mapping identified multi-effects loci for fatty acid related traits in peanut (Arachis hypogaea L.)

Peanut (Arachis hypogaea L.) is an important oil and edible protein crop. The fatty acid composition not only influences the quality of peanut oil but also impacts flavor, shelf life, and consumer health. Peanut oil comprises approximately 80% oleic acid (C18:1) and linoleic acid (C18:2), 10% palmitic acid (C16:0), and the remaining 10% includes stearic acid (C18:0), arachidic acid (C20:0), gadoleic acid (C20:1), behenic acid (C22:0), and lignoceric acid (C24:0). To unravel the genetic foundation of fatty acid content and delve into QTL localization, we utilized high-density SNP microarrays for genotyping the RIL population of ‘SunOleic 97R’ × ‘NC94022’. A genetic linkage map was constructed with 3141 SNP markers, covering a total genetic distance of 3051.81 cM. We identified 60 quantitative trait loci (QTLs) associated with fatty acids which distributed in 11 linkage group, with phenotypic variance explained (PVE) ranging from 1.37% to 44.92%. Notably, the QTL qFAT_A05.1 and qFAT_A08.1 are multiple-effect loci contributing to various fatty acid compositions. Moreover, we identified 15 haplotypes for the QTL qFAT_A05.1 and qFAT_A08.1 through genotyping 178 peanut germplasms. Haplotypes analysis in natural population confirmed the closely relationship of the QTLs with the content of oil, oleic acid, lignoceric acid, palmitic acid and behenic acid. This study serves as a valuable reference for selecting improved peanut genotypes with superior oil quality and desirable fatty acid composition.

In Silico Analysis of Rpp1 Locus-Derived NB-ARC-LRR Domains Reveals Insights into Rust Resistance in Soybean

Soybean rust poses significant economic challenges to soybean producers, resulting in decreased seed size, weight, oil content, and overall crop yield. This study aimed to comprehensively characterize the rust resistance locus Rpp1 identified in soybean genotype EC 241780 and its associated genes within the soybean genome. Our investigation revealed distinctive features of three genes (Glyma18G281700, Glyma18G281600, and Glyma18G281500) located within the Rpp1 locus on chromosome 18. Phylogenetic and domain analyses confirmed the presence of the ULP1 domain in these genes, while motif analysis identified unique patterns exclusive to them. Notably, these genes possessed exclusive isoleucine and glutamic acid residues at positions 836 and 904, along with an unusual expansion of 11 glutamic acid residues at position 861. Expression-data showed significantly higher expression levels of Glyma18G281700 and Glyma18G281600 during leaf trifoliate stages I and II, suggesting their active involvement under adverse conditions. Protein structure analysis revealed that Glyma18G281500 exhibited distinct characteristics compared to the other two genes and displayed a more stable protein structure. This observation may indicate a distinct functional role for Glyma18G281500. In conclusion, our findings suggest that the genes within the Rpp1 locus may contribute to rust resistance, particularly against specific rust races, due to their unique characteristics associated with the ULP1 domain.

Natural stabilizers for functional foods: The role of optimized date seed extracts in nanoemulsion applications

This study explores the potential of date seeds as natural stabilizers in nanoemulsion-based functional foods. Six pre-treatments (control, overnight stirring, high-speed homogenization, ultrasound, microwave, and pH-shift) were investigated to determine the best method for aqueous extraction of date seeds for nanoemulsion optimization and stability studies. The ultrasonic pre-treatment was found to enhance total polyphenols content and antioxidant activity and produce stable nanoemulsions with minimal size variation. A D-optimal design was used for nanoemulsion optimization using varying high-pressure homogenization (HPH) pressure, date seed powder (DSP) concentration, and oil content. The optimal nanoemulsion was formulated at 493.21 bar, with 15% DSP, and 4.13% oil. This nanoemulsion demonstrated stability over a week under refrigerated conditions, particularly at pH 6 and with NaCl concentrations below 100 mM. Our findings indicate that date seed extract can be an effective natural ingredient to stabilize nanoemulsions, promoting the development of novel functional foods. Future studies on enhancing the functional attributes and understanding the properties of the nanoemulsions, including sensory and rheological characteristics and long-term stability across a broader pH range and salt concentrations, would broaden the potential of date seeds as natural stabilizers in nanoemulsion-based functional foods.

Study of the toxicity of the essential oil of Brocchia cinerea

Brocchia cinerea is a North African plant belonging to the Asteraceae family, widely utilized in Algerian folk medicine to treat a variety of illnesses. These therapeutic virtues are mainly due to the plant essential oil. The chemical components of this oil were identified using GC-MS, and the variability in these components' levels was examined in nine samples that were taken at different times from two locations in Algeria's northern Sahara. The contents of the essential oil were found to consist of eight components, varying in concentrations: beta-thujone (46.80%), 1-Methyl-2-(1' methylethenyl) -3'- ethenylcyclopropylmethanol (14.59%), 1,8-Cineole (12.63%), limonen-10-ol (9.47%), 1(7),3,8 o Menthatriene (3.45%), and (-)-Camphor (2.11%). Toxicity studies were conducted in order to assess the safety of the essential oil, namely: LD50 estimation and biochemical blood parameters evaluation. The results showed an LD 50 of 507.5mg/kg close to the LD50 of Beta-thujone (442mg/kg): the main component of the essential oil, making it accountable for the major toxicity. The apparition of seizures as toxic manifestations for higher concentrations confirmed that. The essential oil of Brocchia was noted to be classified as slightly, weakly toxic, and the Beta-thujone contents showed to be within the regulatory accepted values, which makes the use of Brocchia safe within the indicated standards.

Cost-effective production of density-controllable monodisperse spheres for experiments in fluids

Cost-effective production method for making density-controllable monodisperse spheres is demonstrated. A sodium alginate aqueous solution containing gelatin is emulsified with canola oil. The droplet surface is covered with a calcium alginate membrane by dropping the emulsion into a calcium lactate aqueous solution. The content of the canola oil can control the sphere's density. To demonstrate the applicability of the spheres to experimental research, rheological measurements of the suspensions of the spheres were performed. The effective viscosity agrees with the theoretical formula at volume fractions of 0.7%–11.7%. The demonstration highlights that the spheres can function as neutrally buoyant solid particles in studies for the physics of fluids.

These compounds are known for their diverse biological activities and promote the use of such plants in phytopharmaceuticals.

Growth-Promoting Bacteria and Salicylic Acid Improve Essential Oil, Flower Yield, And Compatible Osmolyte Content of Common Yarrow (Achillea millefolium L.) Under Drought Stress

Drought is one of the major constraints on agricultural productivity in arid and semiarid regions. Coping with drought stress involves several adaptations and mitigation strategies such as the use of plant-growth promoting bacteria and salicylic acid, which was examined in this study under two levels of water regimes (well-watered as control and drought stress) in southwest Iran in 2018 and 2020 on common yarrow (Achillea millefolium). Catalase levels significantly increased in response to drought stress and salicylic acid application. Salicylic acid and combined application treatment of both bacteria also resulted in a significant increase in proline compared with the control. Different bacteria strains also resulted in a significant increase in peroxidase and superoxide dismutase when compared with the control. Drought stress, salicylic acid application, and different bacteria strains significantly reduced total protein. The use of salicylic acid and the combined application of both bacteria significantly increased the percentage of essential oil compared with the control. Moreover, 41 compounds were isolated, accounting for 92.08% of the essential oil, with more than 90.00% being volatile terpenes. The main components of yarrow essential oil were borneol (16.79%), flanderin (15.92%), cineole (14.32%), camphor (9.77%), and alpha-pinene (3.44%). In general, growth-promoting bacteria and salicylic acid application constitute an advantageous management practice for the commercial production of Achillea millefolium, increasing the nutraceutical and medicinal values of this species.

Leveraging genetic resource diversity and identification of trait-enriched superior genotypes for accelerated improvement in linseed (Linum usitatissimum L.)

Linseed or flaxseed, native to the Indian subcontinent, had undergone domestication, edaphic selection and evolutionary processes that may have resulted in huge genetic variability in Indian genotypes. To understand the hitherto unexplored genetic diversity for sustainable flaxseed production amid challenges of climate fluctuation and identify trait-specific high-yielding genotypes, 2576 unique linseed accessions were comprehensively evaluated for 36 traits for up to six environments representing two major agroecological zones in India. A wide range of variability was recorded for days to initiation of flowering (42.86–114.99), plant height (43.31–122.88 cm), capsules/plant (64.62–375.87), seed size (6.06–14.44 cm2), thousand seed weight (2.80–11.86 g), seed yield (2.93–17.28 g/plant), oil content (30.14–45.96%) and fatty acid profile especially the key constituent omega-3 fatty acid (25.4–65.88%). Most of the traits such as plant height, flowering time, seed yield, seed and capsule size showed a high or moderately high level of variance coupled with high broad sense heritability indicating precise capturing of less heritable quantitative traits. The infraspecific classification of the tested collection revealed the seed/oil type (2498 accessions) as the dominant morphotype over dual-purpose/fiber flax (78 accessions) in the conserved collection. Correlation analysis indicated a significant positive association between flowering time, plant height, days to maturity and oil content. Trait-specific superior genotypes for earliness (50% flowering in < 60 days, maturity in < 122 days), bold seeds with high thousand seed weight (> 11 g), capsules/plant (> 350), oil content (> 45%) and fatty acid composition (> 65% alpha-linolenic acid) were identified to aid genetic improvement of linseed and to broaden the narrow genetic base.

Evaluation of the quality of products from multiple industrial-scale composting treatment facilities for kitchen waste and exploration of influencing factors

The aerobic composting process is extensively utilized to manage kitchen waste. Nonetheless, the variability in the quality of compost derived from engineering practices which significantly hinders its broader industrial application. This work investigated the final products of kitchen waste compost at multiple industrial-scale treatment facilities utilizing three distinct aerobic composting processes in a bid to explore key factors affecting compost quality. The quality evaluation was based on technical parameters like seed germination index (GI), and limiting factors such as heavy metal content. The results showed that most of the compost products failed to meet the established standards, with GI being the primary limiting indicator. Furthermore, maturity assessments suggested that compost with low GI exhibited reduced humification could not be recommended for agricultural use. The investigation delved into the primary determinants of GI, focusing on risk factors such as the oil and salt of kitchen waste, and the microbial community of the humification driving forces. The results indicated that products with low GI had higher oil and salt content and a relatively simple microbial community. A thorough analysis suggested that excessive levels oil and salt were potential influencing factors on GI, as they stimulated the activity of acid-producing bacteria like Lactobacillus, suppressed the activity of humification-promoting bacteria such as Actinomarinales, and influenced the decomposition and humification processes of organic matter and total nitrogen, thereby affecting product quality. The findings provide valuable insights for improving kitchen waste compost products for agricultural applications.

Effect of a SILICA/HPAM Nanohybrid on Heavy Oil Recovery and Treatment: Experimental and Simulation Study.

The addition of nanoparticles has been presented as an alternative approach to counteract the degradation of polymeric solutions for enhanced oil recovery. In this context, a nanohybrid (NH34) of partially hydrolyzed polyacrylamide (MW ∼12 MDa) and nanosilica modified with 2% 3-aminopropyltriethoxysilane (nSiO2-APTES) was synthesized and evaluated. NH34 was characterized by using dynamic light scattering, Fourier-transform infrared spectroscopy, and thermogravimetric analysis. Fluid-fluid tests assessed its viscosifying power, mechanical stability, filterability, and emulsion behavior. Rock-fluid tests were carried out to determine the nanohybrid's adsorption in porous media, the inaccessible pore volume (IPV), and the resistance (RF) and residual resistance factors (RRF). These tests were conducted under the conditions of a Colombian field. NH34 results were compared with four (4) commercial polymers (P34, P88, P51, and PA2). The viscosifying power of NH34 was observed to be similar to that of the four commercial polymers at a lower concentration, but it exhibits more resistance to mechanical and chemical degradation. The evaluation of the emulsion behavior showed that the nanohybrid neither changed the dehydration process nor altered the crude oil viscosity, favoring its extraction at the wellhead. However, the water clarification treatment must be adjusted because the oil and grease contents and turbidity increase with the residual concentration of NH34. Incremental oil recovery factors obtained by numerical simulation (compared to waterflooding) were P51 (5.5%) > P34 (4.9%) > P88 (4.8%) > NH34 (2.6%) > PA2 (0.9%). The polymers P51, P34, and P88 had a better recovery factor than NH34 and PA2 due to their lower values of residual adsorption and IPV. Few studies have been reported on polymer nanohybrids' emulsion and flow behavior. Therefore, further research is needed to enhance our understanding of the fundamental enhanced oil recovery mechanisms associated with polymer nanohybrids.

A novel foaming formulation with excellent salt-resistant for foam assisted deliquification of gas wells

In this paper, an excellent foaming formula for natural gas well deliquification was developed, which was based on the synthesized dodecyl ethylethanolamine (DEEA), commercially obtained cocamidopropyl betaine (CAPB) and sodium lauryl glutamate (SLG). The foaming properties and liquid unloading properties were studied, which showed that the optimal molar ratio of DEEA/CAPB/SLG ternary complex turned out to be 14:21:15. At a total concentration of 15 mM in the liquid phase, the optimal DEEA/CAPB/SLG mixture exhibited excellent foaming and liquid unloading capability at various conditions of methanol, condensate oil and salts contents and temperatures. At the methanol content of 45%, the foaming efficiency and liquid unloading efficiency of the DEEA/CAPB/SLG mixture were measured to be 100% and 25.5 ± 2.2%, respectively. When the condensate oil content was 10–30%, the liquid unloading efficiency ranged from 18.0 ± 2.1% to 25.0 ± 2.5%, which was much higher than that (8.3 ± 0.9%) obtained without condensate. The presence of salts retarded the performance of the DEEA/CAPB/SLG mixture, however, the addition of a chelating agent, trisodium nitrilotriacetic acid (NTA), to DEEA/CAPB/SLG could enhance the foaming efficiency and unloading performance at a salinity level of up to 41 × 104 mg/L, which might be the highest salt-resistant level of the gas well foaming mixture. The introduction of 10% methanol exhibited a positive effect on the DEEA/CAPB/SLG mixture’s foaming and liquid unloading performance against temperature (up to 90 °C). At 90 °C, the DEEA/CAPB/SLG foam could remove almost all the liquid from the column.

Deciphering the Genetic Basis of Kernel Composition in a Maize Association Panel.

The primary objective in contemporary maize breeding is to pursue high quality alongside high yield. Deciphering the genetic basis of natural variation in starch, protein, oil, and fiber contents is essential for manipulating kernel composition, thereby enhancing the kernel quality and meeting growing demands. Here, we identified 12 to 88 statistically significant loci associated with kernel composition traits through a genome-wide association study (GWAS) using a panel of 212 diverse inbred lines. A regional association study pinpointed numerous causal candidate genes at these loci. Coexpression and protein-protein interaction network analyses of candidate genes revealed several causal genes directly or indirectly involved in the metabolic processes related to kernel composition traits. Subsequent mutant experiment revealed that nonsense mutations in ZmTIFY12 affect starch, protein, and fiber content, whereas nonsense mutations in ZmTT12 affect starch, protein, and oil content. These findings provide valuable guidance for improving kernel quality in maize breeding efforts.

The Effect of Apis mellifera L. Pollination on Seed Yield and Nutritional Qualities of Sesamum indicum L. in Dale Sedi District of Western Oromia, Ethiopia

ABSTRACTThe development of blossoming seed plants that provide a genetically diverse crop of progeny depends on pollination. Sesamum indicum is an oilseed crop and requires both self and cross‐pollination that varies based on insect type, crop variety, and environmental factors. Hence, the experiment was conducted for two consecutive years (2022 and 2023) to the effect of Apis mellifera L. pollination on yield, germination, and nutritional qualities of S. indicum (Dicho variety). A completely randomized block design with three treatments was used, and each treatment was replicated four times. Insects from open plot were counted from 1 m × 1 m quadrant/5 min. Seed yield and yield parameters and germination rates were recorded based on standard methods. Oil content was analyzed by Soxhlet extraction. From the study, 13 insects were identified of which 69.2% were categorized under the order Hymenoptera. A combined mean of plant height, branch/plant, and number of pod/plant showed statistically no difference (p &gt; 0.05) among treatments. However, the number of seeds/pod, 1000 seed weight, and yield (quintal)/ha produced by an open plot and a plot caged with A. mellifera were statistically higher (p &lt; 0.05) as compared with the closed plot. The percentage increment in seed yield (quintal)/ha were 17.16% and 20.33% for the open plot and the plot caged with bees, respectively. The seed germination was found to be maximum in the open plot (88.9%) followed by a plot caged with A. mellifera (86.68%) and a closed plot (60.46%). A measurable variation (p &lt; 0.05) in oil content(%) was recorded among the treatments with the maximum from a plot caged with bees (54.24 ± 0.27) followed by an open plot (52.04 ± 0.58) and closed plot (48.81 ± 0.24). These findings suggest that pollinators, including honey bees, A. mellifera visiting S. indicum can enhance yields, germination rates, and oil content.

Selected Soluble Dietary Fibres as Replacers of Octenyl Succinic Anhydride (OSA) Starch in Spray-Drying Production of Linseed Oil Powders Applied to Apple Juice

The aim of the study was to compare two kinds of soluble dietary fibres in a mixture with OSA-starch as wall components of linseed oil capsules. Comparison was made based on emulsion (droplet size, polydispersity index, and viscosity) and powder properties (outer structure, colour, surface oil content, and encapsulation efficiency). Additionally, linseed oil powders were applied to the food model (apple juice) and the colour, physical stability, and volatile compound profile of fortified juice were determined. Although the obtained linseed oil emulsions with different compositions of polysaccharide components showed some variation in droplet size, polydisperse index and viscosity, their encapsulation efficiency by spray-drying was very high (&gt;98%). The powders produced had a similar structure and low surface oil content, and their 2% addition to apple juice did not change its stability and only slightly decreased its colour lightness and yellowness. However, greater differences in the volatile compounds of obtained juices were observed. Overall, the added powders reduced the volatility of aroma compounds typical of apple juice but introduced propanal and hexanal, especially the powders with the highest OSA-starch share.
