Persistence and Culturability of Escherichia coli under Induced Toxin Expression

Antibiotics
Background/Objectives: Bacteria are well known to enter dormancy under stress conditions. However, the mechanisms of different dormancy-related phenotypes are still under debate and many questions remain unanswered.

Growth of engineered Pseudomonas putida KT2440 on glucose, xylose, and arabinose: Hemicellulose hydrolysates and their major sugars as sustainable carbon sources

GCB Bioenergy, 2019
Lignocellulosic biomass is the most abundant bioresource on earth containing polymers mainly consisting of d‐glucose, d‐xylose, l‐arabinose, and further sugars.

A P-type ATPase importer that discriminates between essential and toxic transition metals [PDF]

, 2009
Transition metals, although being essential cofactors in many physiological processes, are toxic at elevated concentrations. Among the membrane-embedded transport proteins that maintain appropriate intracellular levels of transition metals are ATP-driven

Crystal structure of racemic 2-[(β-arabinopyranosyl)sulfanyl]-4,6-diphenylpyridine-3-carbonitrile

Acta Crystallographica Section E: Crystallographic Communications, 2018
In the racemic title compound, C23H20N2O4S, the sulfur atom is attached equatorially to the sugar ring with unequal S—C bonds, viz.: S—Cs = 1.808 (2) and S—Cp = 1.770 (2) Å (s = sugar, p = pyridyl).

Information on Transcriptional Regulation and Signal Transduction of _Escherichia coli_ K-12 Integrated in the Database RegulonDB. [PDF]

, 2010
Since its inception, RegulonDB ("http://regulondb.ccg.unam.mx/":http://regulondb.ccg.unam.mx/) has been a database that compiles information about the regulation of transcription initiation of _Escherichia coli_ K-12. However, we are aware that

Effects of addition of different sources and doses of sugars on in vitro digestibilities of dry matter, fibre and cell wall monosaccharides of corn silage in ruminants

Animal, 2020
In ruminant diets, soluble sugar is an important factor in the digestive process. The objective of this study was to evaluate the effects of the source and dose of soluble sugars, under controlled pH conditions, on the in vitro digestibility of DM, fibre

Regulation of metabolism in Escherichia coli during growth on mixtures of the non-glucose sugars: arabinose, lactose, and xylose

Scientific Reports, 2018
Catabolite repression refers to the process where the metabolism of one sugar represses the genes involved in metabolizing another sugar. While glucose provides the canonical example, many other sugars are also known to induce catabolite repression ...

Efficacy of L-Arabinose in Lowering Glycemic and Insulinemic Responses: The Modifying Effect of Starch and Fat

Foods, 2022
L-arabinose is a bio-active compound derived from the side-streams of plant food processing. L-arabinose lowers glycemic and insulinemic responses when added to simple water-based sugary liquids.

A unified design space of synthetic stripe-forming networks [PDF]

, 2014
Synthetic biology is a promising tool to study the function and properties of gene regulatory networks. Gene circuits with predefined behaviours have been successfully built and modelled, but largely on a case-by-case basis.

Fermentation of glucose-xylose-arabinose mixtures by a synthetic consortium of single-sugar-fermenting Saccharomyces cerevisiae strains.

FEMS Yeast Research, 2018
d-Glucose, d-xylose and l-arabinose are major sugars in lignocellulosic hydrolysates. This study explores fermentation of glucose-xylose-arabinose mixtures by a consortium of three 'specialist' Saccharomyces cerevisiae strains.
