Production of Acetoin through Simultaneous Utilization of Glucose, Xylose, and Arabinose by Engineered Bacillus subtilis
Glucose, xylose and arabinose are the three most abundant monosaccharide found in lignocellulosic biomass. Effectively and simultaneously utilization of these sugars by microorganisms for production of the biofuels and bio-chemicals is essential toward directly fermentation of the lignocellulosic biomass. In our previous study, the recombinant Bacillus subtilis 168ARSRCPΔacoAΔbdhA strain was al...
متن کاملSimultaneous utilization of glucose, xylose and arabinose in the presence of acetate by a consortium of Escherichia coli strains
BACKGROUND The efficient microbial utilization of lignocellulosic hydrolysates has remained challenging because this material is composed of multiple sugars and also contains growth inhibitors such as acetic acid (acetate). Using an engineered consortium of strains derived from Escherichia coli C and a synthetic medium containing acetate, glucose, xylose and arabinose, we report on both the mic...
متن کاملNovel evolutionary engineering approach for accelerated utilization of glucose, xylose, and arabinose mixtures by engineered Saccharomyces cerevisiae strains.
Lignocellulosic feedstocks are thought to have great economic and environmental significance for future biotechnological production processes. For cost-effective and efficient industrial processes, complete and fast conversion of all sugars derived from these feedstocks is required. Hence, simultaneous or fast sequential fermentation of sugars would greatly contribute to the efficiency of produ...
متن کاملSimultaneous utilization of glucose and xylose for lipid production by Trichosporon cutaneum
BACKGROUND Biochemical conversion of lignocellulose hydrolysates remains challenging, largely because most microbial processes have markedly reduced efficiency in the presence of both hexoses and pentoses. Thus, identification of microorganisms capable of efficient and simultaneous utilization of both glucose and xylose is pivotal to improving this process. RESULTS In this study, we found tha...
متن کاملCatabolite regulation of Bacillus subtilis acetate and acetoin utilization genes by CcpA.
The Bacillus subtilis acsA (acetyl coenzyme A synthetase) and acuABC (acetoin utilization) genes were previously identified in the region downstream from the ccpA gene, which encodes a protein required for catabolite repression of the amyE (alpha-amylase) gene. The acsA and acuABC genes are divergently transcribed, with only 20 bp separating the -35 sequences of their promoters. Expression of t...
