Alleviation of carbon catabolite repression in Enterobacter aerogenes for efficient utilization of sugarcane molasses for 2,3-butanediol production
BACKGROUND Due to its cost-effectiveness and rich sugar composition, sugarcane molasses is considered to be a promising carbon source for biorefinery. However, the sugar mixture in sugarcane molasses is not consumed as efficiently as glucose in microbial fermentation due to complex interactions among their utilizing pathways, such as carbon catabolite repression (CCR). In this study, 2,3-butane...
متن کاملProduction of 2,3-butanediol by Bacillus stearothermophilus: fermentation and metabolic pathway
The fermentation of different sugars by Bacillus stearothermophilus ATCC 2027 to obtain 2,3-butanediol is described. Fermentation tests in shake flasks show the complete conversion of sucrose to butanediol (91% yield) and acetoin (3-hydroxy-2-butanone) using a starting sugar concentration of 30 g/L. A similar result is obtained with sugar cane molasses, whereas glucose and fructose afford lower...
متن کاملExtractive Capacity of Oleyl Alcohol on 2, 3-Butanediol Production in Fermentation Process with Use of Klebsiella pneumoniae PTCC 1290
Recovery of metabolites from fermentation broth by solvent extraction can be used to optimize fermentation processes. End-product reutilization, low product concentration and large volumes of fermentation broth and the requirements for large bioreactors, in addition to the high cost largely contributed to the decline in fermentative 2,3-butanediol production. Extraction can successfully be ...
متن کاملInvestigation of yeast performances in the fermentation of beet and cane molasses to ethanol production
___________________________________________________________________________________________ Abstract In commercial ethanol production producers often use sugarcane or sugar beet molasses as raw material due to their abundance and low costs. The most employed microorganism used for fermentation is Saccharomyces cerevisiae yeast due to its ability to hydrolyze sucrose from cane or beet molasses i...
