“…Cotton ( Gossypium spp.) is the leading natural fiber crop for the manufacture of textiles and an important source of vegetable oil and protein for humans and livestock (Yu et al, 2012 ; Gore et al, 2014 ; Liu et al, 2017a ), as well as renewable raw materials for various industrial products such as biofuels, lubricants, and hydraulic oils (Jiao et al, 2013 ; Sinha and Murugavelh, 2016 ). Cottonseed oil and protein account for 17–27% and 12–32% of seed weight, respectively, and vary with cotton species, varieties, and measuring methods (Wu et al, 2009 ; Yu et al, 2012 ).…”

Cotton (Gossypium spp.) is a leading natural fiber crop and an important source of vegetable protein and oil for humans and livestock. To investigate the genetic architecture of seed nutrients in upland cotton, a genome-wide association study (GWAS) was conducted in a panel of 196 germplasm resources under three environments using a CottonSNP80K chip of 77,774 loci. Relatively high genetic diversity (average gene diversity being 0.331) and phenotypic variation (coefficient of variation, CV, exceeding 3.9%) were detected in this panel. Correlation analysis revealed that the well-documented negative association between seed protein (PR) and oil may be to some extent attributable to the negative correlation between oleic acid (OA) and PR. Linkage disequilibrium (LD) was unevenly distributed among chromosomes and subgenomes. It ranged from 0.10–0.20 Mb (Chr19) to 5.65–5.75 Mb (Chr25) among the chromosomes and the range of Dt-subgenomes LD decay distances was smaller than At-subgenomes. This panel was divided into two subpopulations based on the information of 41,815 polymorphic single-nucleotide polymorphism (SNP) markers. The mixed linear model considering both Q-matrix and K-matrix [MLM(Q+K)] was employed to estimate the association between the SNP markers and the seed nutrients, considering the false positives caused by population structure and the kinship. A total of 47 SNP markers and 28 candidate quantitative trait loci (QTLs) regions were found to be significantly associated with seven cottonseed nutrients, including protein, total fatty acid, and five main fatty acid compositions. In addition, the candidate genes in these regions were analyzed, which included three genes, Gh_D12G1161, Gh_D12G1162, and Gh_D12G1165 that were most likely involved in the control of cottonseed protein concentration. These results improved our understanding of the genetic control of cottonseed nutrients and provided potential molecular tools to develop cultivars with high protein and improved fatty acid compositions in cotton breeding programs through marker-assisted selection.

“…Biodiesel fuel mixes (B10 and B20) had a typical fuel utilization of 0.34 kg/(kW•h) and 0.38 kg/(kW•h), separately. The biodiesel mixes B10 and B20 brought about generously improved discharge qualities with lower unburnt HC, CO emanations and customary diesel fuel alternatives [12].…”

A significant portion of the automobile and industrial sector is mostly dependent on the running of diesel engines as it is efficient and shifts a large of the goods around the globe and power various equipment. Also, as the use of energy as diesel fuel is increasing enormously with the expansion of industrial growth, diversification, this led to the accelerating global emissions, global climatic change, health issues, and exhaustion of fuels. To succumb this, alternative fuel is needed to fight against the ill effects and as a replacement to diesel fuel. Thus, vegetable oils as alternative fuels are drawing more attention as they are renewable and do not address the problem of greenhouse gas. In the present work, the cottonseed oil was chosen as the favorite among the vegetable oils due to its advantages like less pollutant level, excessive availability, etc. The transesterification process was used to produce the cottonseed oil biodiesel. This research aims to investigate efficiency, emission characteristics by using smooth diesel, cottonseed oil, and mixtures with varying composition from 20 % to 80 % in 20 % steps to identify sustainable fuel as a substitute for existing fuel and to overcome fuel demand and enviro effects. This test was conducted on single-cylinder four-stroke water-cooled diesel engines. From the results, it was revealed that cottonseed oil and its blends have a significant influence on performance and emission characters. Keywords: water-cooled diesel engine, emission character, cottonseed oil, sustainable fuel.

“…The contribution towards good biodiesel yield is most likely associated with the excellent reaction between methanol and oil when the methanol/oil ratio is increased (Sirisomboonchai et al 2015). However, when the ratio exceeded the optimum value, the reaction rate dropped significantly since too much methanol could result in the reduction of catalyst concentration and shifting the equilibrium to the reactant side (Sinha & Murugavelh 2016). In addition, the excessive amount of methanol caused the glycerol to dissolve and resulted in difficulty during the separation of biodiesel and glycerol (Moradi & Mohammadi 2014).…”

This work focuses on the catalytic potential of K-impregnated staghorn coral as a catalyst in methyl esters production via methanolysis of waste cooking oil (WCO). The prepared catalyst was analyzed by Hammett indicators, XRF, Brunauer-Emmett-Teller (BET)-N2 adsorption method, ATR-FTIR, TGA, XRD and SEM to determine its physicochemical properties. ATR-FTIR and XRD results confirmed the formation of K 2 O species upon KOH impregnation, thus, resulting in good catalytic activity. Reaction parameters such as methanol to oil ratio, reaction time and amount of catalyst were evaluated to find out the best conditions for the transesterification process. About 89.51 ± 4.78 % of biodiesel contents were obtained under the optimum conditions.
