Cloning, Expression, and Characterization of Bacterial l-Arabinose 1-Dehydrogenase Involved in an Alternative Pathway of l-Arabinose Metabolism [PDF]

Journal of Biological Chemistry, 2006
Azospirillum brasiliense converts L-arabinose to alpha-ketoglutarate via five hypothetical enzymatic steps. We purified and characterized L-arabinose 1-dehydrogenase (EC 1.1.1.46), catalyzing the conversion of L-arabinose to L-arabino-gamma-lactone as an enzyme responsible for the first step of this alternative pathway of L-arabinose metabolism.

The sRNA vvrr1 Modulates the VarS/VarA‐Csr System via LeuO to Regulate Biofilm Formation and Virulence in Vibrio alginolyticus

Animal Research and One Health, EarlyView.
vvrr1, a small RNA, post‐transcriptionally represses the transcriptional regulator LeuO, which directly inhibits the VarS/VarA two‐component system. This triggers a Csr cascade that relieves LuxO repression, ultimately modulating exopolysaccharide production to control biofilm formation and virulence in Vibrio alginolyticus.

Second‐Generation Polyhydroxybutyrate Production From Pretreated Corn Lignocellulosic Fraction as a Strategy to Repurpose by Products From the Corn‐Processing Chain

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Lignocellulosic residues are non‐cost, non‐edible, renewable feedstocks that can be used in polyhydroxybutyrate (PHB) production. PHB is a bioplastic synthetized by microorganisms, formed intracellularly under stressful growth conditions; however, its production costs are high, representing the major drawback for fossil‐based plastics ...

Dissecting the complex regulation of pentose utilization in Aspergillus niger

Current Research in Microbial Sciences
L-Arabinose and D-xylose are abundantly present in nature as components of plant cell wall polysaccharides. Fungi mainly use the Pentose Catabolic Pathway (PCP) for conversion of these sugars into central carbon metabolism.

Genome-scale consequences of cofactor balancing in engineered pentose utilization pathways in Saccharomyces cerevisiae. [PDF]

PLoS ONE, 2011
Biofuels derived from lignocellulosic biomass offer promising alternative renewable energy sources for transportation fuels. Significant effort has been made to engineer Saccharomyces cerevisiae to efficiently ferment pentose sugars such as D-xylose and ...

Fermentation of xylose, arabinose, glucose, their mixtures and sugarcane bagasse hydrolyzate by yeast Pichia stipitis for ethanol production

Energy Reports, 2020
Xylose, arabinose and glucose were studied their fermentabilities to ethanol by yeast Pichia stipitis. The experiments were conducted by using 1.0, 5.0, 10.0 and 20.0 g/l of mono-saccharide solutions in a close fermentation system at 30 °C with 100-rpm ...

Integrated biorefinery for cellulosic ethanol and spherical nanolignin production from coconut waste

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Green coconut waste was subjected to different fractionation methods to obtain integrated lignin nanoparticles and cellulosic ethanol. Pretreatment with gradual addition of dilute sulfuric acid provided a higher structural hemicellulose precursor yield (68.2%).
