Production of Acetoin through Simultaneous Utilization of Glucose, Xylose, and Arabinose by Engineered Bacillus subtilis. [PDF]

PLoS ONE, 2016
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 ...

Using Synthetic Glycans to Investigate Anti‐Glycan Antibodies and Explore Their Medical Potential

Angewandte Chemie International Edition, EarlyView.
Anti‐glycan antibodies are essential in health and disease. Access to novel glycan structures paves the way for progress in antibody profiling for biomarker discovery, antibody development, and vaccine design. We summarize the strategies to synthesize and utilize synthetic glycans for the development and application of anti‐glycan antibodies in basic ...

Genomic and metabolic instability during long-term fermentation of an industrial Saccharomyces cerevisiae strain engineered for C5 sugar utilization

Frontiers in Bioengineering and Biotechnology
The genetic stability and metabolic robustness of production strains is one of the key criteria for the production of bio-based products by microbial fermentation on an industrial scale. These criteria were here explored in an industrial ethanol-producer

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.

Polysaccharides with Arabinose: Key Players in Reducing Chronic Inflammation and Enhancing Immune Health in Aging

Molecules
Aging is associated with a decline in physiological performance leading to increased inflammation and impaired immune function. Polysaccharides (PLs) found in plants, fruits, and fungi are emerging as potential targets for therapeutic intervention, but ...

The Penicillium chrysogenum transporter PcAraT enables high-affinity, glucose-insensitive l-arabinose transport in Saccharomyces cerevisiae

Biotechnology for Biofuels, 2018
Background l-Arabinose occurs at economically relevant levels in lignocellulosic hydrolysates. Its low-affinity uptake via the Saccharomyces cerevisiae Gal2 galactose transporter is inhibited by d-glucose. Especially at low concentrations of l-arabinose,

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 ...

Single cell kinetics of phenotypic switching in the arabinose utilization system of E. coli.

PLoS ONE, 2014
Inducible switching between phenotypes is a common strategy of bacteria to adapt to fluctuating environments. Here, we analyze the switching kinetics of a paradigmatic inducible system, the arabinose utilization system in E. coli.
