Plasmid-encoded diacetyl (acetoin) reductase in Leuconostoc pseudomesenteroides

, 2003
A plasmid-borne diacetyl (acetoin) reductase (butA) from Leuconostoc pseudomesenteroides CHCC2114 was sequenced and cloned. Nucleotide sequence analysis revealed an open reading frame encoding a protein of 257 amino acids which had high identity at the ...

New acetoin reductases from Bacillus stearothermophilus: meso- and 2R,3R-butanediol as fermentation products

, 2011
The fermentation of sucrose with Bacillus stearothermophilus ATCC 2027 afforded 2R,3R- and meso-2,3-butanediol together with R-acetoin following the bacterial catabolic pathway.

REDUCTION OF ACETOIN TO 2,3 BUTANEDIOL IN KLEBSIELLA PNEUMONIAE: A STEREOCHEMICAL MODEL AND KINETICS

, 1981
The fermentation of D-xylose by Klebsiella pneumoniae (ATCC 8724) produces a mixture of 2,3 butanediol stereoisomers. These isomers were separated by aqueous liquid chromatography and identified as meso and L(+) 2,3 butanediol, the former being the major

D-2,3-Butanediol Production Due to Heterologous Expression of an Acetoin Reductase in Clostridium acetobutylicum

, 2011
Acetoin reductase (ACR) catalyzes the conversion of acetoin to 2,3-butanediol. Under certain conditions Clostridium acetobutylicum ATCC 824 (and derived strains) generates both D- and L-stereoisomers of acetoin, but due to the lack of an ACR enzyme, does

OPTIMIZATION OF ACETOIN PRODUCTION BY Hanseniaspora guilliermondii USING EXPERIMENTAL DESIGN

, 2002
- The synthesis of acetoin in YM medium and under aerobic conditions by Hanseniaspora guilliermondii was studied. Experimental design and surface response analysis were employed to evaluate the influence of glucose concentration, temperature and pH on ...

Efficient production of acetoin in Saccharomyces cerevisiae by disruption of 2,3-butanediol dehydrogenase and expression of NADH oxidase

, 2016
Acetoin is widely used in food and cosmetic industry as taste and fragrance enhancer. For acetoin production in this study, Saccharomyces cerevisiae JHY605 was used as a host strain, where the production of ethanol and glycerol was largely eliminated by ...

Genome Sequence of Staphylococcus aureus PX03, an Acetoin-Producing Strain with a Small-Sized Genome

, 2017
Staphylococcus aureus PX03 can produce acetoin efficiently. Here, we present a 2.38-Mb assembly of its genome sequence, which might provide further insights into the molecular mechanism of its acetoin biosynthesis to further improve its ...

The volatile organic compound acetoin enhances the colonization of Azorhizobium caulinodans ORS571 on Sesbania rostrata

Chemoreceptors play a crucial role in assisting bacterial sensing and response to environmental stimuli. Genome analysis of Azorhizobium caulinodans ORS571 revealed the presence of 43 putative chemoreceptors, but their biological functions remain largely
