With significant technological advances in metabolic engineering, there are currently available efficient recombinant yeast strains capable of fermenting lignocellulosic sugars (i.e., glucose and xylose) to bioethanol. Conventional batch fermentation, preferred in most bioprocesses, may not provide the most appropriate environments for those engineered strains to perform their best. In this art...

Here, we report the draft genome sequence of Saccharomyces cerevisiae strain NCIM3186 used in bioethanol production from sweet sorghum. The size of the genome is approximately 11.9 Mb and contains 5,347 protein-coding genes.

Abstract Bioethanol production has been a challenge for the researchers with respect to enhancing bioethanol yield. In this study, we are reporting an efficient novel method produce bioethanol. The process comprises co-culture technique from wheat straw, by co-culturing Bacillus licheniformis and Saccharomyces cerevisiae. Simultaneous saccharification fermentation allows straw hydrolysis cellul...

Fossil fuels are a major contributor to climate change and environmental pollution, as the demand for energy production increases, alternative sources becoming more attractive. Bioethanol reduce reliance on fossil can be compatible with existing fleet of internal combustion engines. is typically produced via microbial fermentation fermentable sugars. Traditional feedstocks (first- generation) i...

BACKGROUND An optimal valorization of plant biomasses to produce biofuels requires a good knowledge of the available contents and molecular composition of the main chemical components, which changes with the harvesting date. Therefore, we assessed the influence of harvesting date on the chemical characteristics of various energy crops in the context of their conversion to biofuels. RESULTS We...

Symbiotic association of legumes with rhizobia frequently results in higher photosynthesis and soluble carbohydrates in comparison with nitrate-fed plants, which might improve its potential for biomass conversion into bioethanol. A greenhouse experiment was conducted to examine the effects of nitrogen source and water availability on stem characteristics and on relationships between carbohydrat...

Microalgal biofuel production from wastewater has economic and environmental advantages. This article investigates the lipid production from high chemical oxygen demand (COD) bioethanol wastewater without dilution or additional nutrients, using a newly isolated heterotrophic microalga, Chlorella vulgaris LAM-Q. To enhance lipid accumulation, the combined effects of important operational paramet...

Cassava ranks fifth among the starch producing crops of the world, its annual bioethanol yield is higher than for any other crop. Cassava cultivar KU50, the most widely grown cultivar for non-food purposes is susceptible to Sri Lankan cassava mosaic virus (SLCMV). The objective of this work was to engineer resistance to SLCMV by RNA interference (RNAi) in order to increase biomass yield, an imp...

The progressive rise in energy crisis followed by green house gas (GHG) emissions is serving as the driving force for bioethanol production from renewable resources. Current bioethanol research focuses on lignocellulosic feedstocks as these are abundantly available, renewable, sustainable and exhibit no competition between the crops for food and fuel. However, the technologies in use have some ...

Bioethanol was produced from the three different agro-industrial biomass residues, i.e., sugarcane bagasse (SB), rice husk (RH) and corn cob (CC)) at 35°C, 120hr with 90g of each substrate. 2% H2SO4 used for hydrolysis samples while 3g yeast (saccharomyces cerevisiae) fermentation. Simple distillation fermented broth. The concentration reducing sugar ethanol, quantity bioethanol as well physica...
