Bioethanol Production from Fermentable Sugar Juice
Bioethanol production from renewable sources to be used in transportation is now an increasing demand worldwide due to continuous depletion of fossil fuels, economic and political crises, and growing concern on environmental safety. Mainly, three types of raw materials, that is, sugar juice, starchy crops, and lignocellulosic materials, are being used for this purpose. This paper will investiga...
متن کاملAltering Lignin Composition to Improve Biofuel Production.
Through the wonders of fermentation, simple sugars derived from enzymatic degradation of cellulose and hemicellulose in the plant cell wall are converted to the biofuel cellulosic ethanol, an attractive alternative to fossil fuels and grain-derived ethanol (Solomon et al., 2007). Before this fermentation takes place, however, the rigid lignin network in the cell wall must be loosened with hot a...
متن کاملEmpirical Modelling and Prediction of Sugarcane Yields from Field Records
Commercial sugarcane records for 19 seasons from 146 fields were obtained from five estates in the KwaZulu-Natal Midlands. Extensive editing and cleaning of the agronomic records was required. Regression models were developed, and depending on the predictor variables selected, the best model accounted for 55% of the observed yield variation, based on 535 crop cycles. The final models were valid...
متن کاملAlkaline twin-screw extrusion pretreatment for fermentable sugar production
BACKGROUND The inevitable depletion of fossil fuels has resulted in an increasing worldwide interest in exploring alternative and sustainable energy sources. Lignocellulose, which is the most abundant biomass on earth, is widely regarded as a promising raw material to produce fuel ethanol. Pretreatment is an essential step to disrupt the recalcitrance of lignocellulosic matrix for enzymatic sac...
متن کاملAltered lignin biosynthesis using biotechnology to improve lignocellulosic biofuel feedstocks.
Lignocellulosic feedstocks can be converted to biofuels, which can conceivably replace a large fraction of fossil fuels currently used for transformation. However, lignin, a prominent constituent of secondary cell walls, is an impediment to the conversion of cell walls to fuel: the recalcitrance problem. Biomass pretreatment for removing lignin is the most expensive step in the production of li...
