Ethanol production from sweet sorghum by Saccharomyces cerevisiae DBKKUY-53 immobilized on alginate-loofah matrices.
Ethanol production from sweet sorghum juice (SSJ) using the thermotolerant Saccharomyces cerevisiae strain DBKKUY-53 immobilized in an alginate-loofah matrix (ALM) was successfully developed. As found in this study, an ALM with dimensions of 20×20×5mm3 is effective for cell immobilization due to its compact structure and long-term stability. The ALM-immobilized cell system exhibited greater eth...

متن کاملEthanol production from sweet sorghum juice under very high gravity conditions: Batch, repeated-batch and scale up fermentation
Batch ethanol fermentations from sweet sorghum juice by Saccharomyces cerevisiae NP 01 were carried out in a 500 ml air-locked Erlenmeyer flask under very high gravity (VHG) and static conditions. The maximum ethanol production efficiency was obtained when 9 g l of yeast extract was supplemented to the juice. The ethanol concentration (P), productivity (Qp) and yield (Yp/s) were 120.24 ± 1.35 g...
متن کامل[Ethanol production from sweet sorghum stalks by advanced solid state fermentation (ASSF) technology].
A robust strain of the species Saccharomyces cerevisiae CGMCC1949 was screened and identified, and advanced solid state fermentation (ASSF) technology for fuel ethanol production from sweet sorghum stalks was thus developed. The fermentation time was shortened to less than 30 h, and ethanol yield was 92% of its theoretical maximum. And in the meantime, the cost-effective storage was established...
متن کاملFermentation kinetics and ethanol production from different sweet sorghum varieties
In recent years bioethanol fuels derived from agricultural biomass resources or waste have been considered the cleanest liquid fuel alternative to fossil fuels. Ethanol consumption is expected to reach 11.2 billion gallons by 2012. Sweet sorghum, grown in the Southeast and Midwest states in US, contains 14%-20% fermentable sugar and is an ideal feedstock, owing to its ease of fermentation by ye...
