Structure and mechanism of acetolactate decarboxylase [PDF]

, 2013
Acetolactate decarboxylase catalyzes the conversion of both enantiomers of acetolactate to the (R)-enantiomer of acetoin, via a mechanism that has been shown to involve a prior rearrangement of the non-natural (R)-enantiomer substrate to the natural (S ...

On the Formation of Acetoin by Acetobacter [PDF]

Journal of General Microbiology, 1959
SUMMARY: The formation of acetoin was studied with 44 strains of the genus Acetobacter, when growing on a medium containing DL-lactate as the main carbon source. Most of the strains produced only limited amounts of acetoin. However, strains of the species A.

Maternally-transmitted microbiota affects odor emission and preference in Drosophila larva

Scientific Reports, 2017
Experimental studies show that early sensory experience often affects subsequent sensory preference, suggesting that the heterogeneity of sensory cues in nature could induce significant inter-individual behavioral variation, potentially contributing to ...

Conversion of Enantiomers during the Separation of Acetoin from Fermentation Broth

Fermentation, 2022
Acetoin (AC) is an important platform compound with two enantiomers (R)-AC and (S)-AC. Due to its unique spatial structure, optically pure AC has particularly high application in asymmetric synthesis.

Capacitive Field‐Effect Biosensor Applied for the Detection of Acetoin in Alcoholic Beverages and Fermentation Broths [PDF]

, 2021
An acetoin biosensor based on a capacitive electrolyte–insulator–semiconductor (EIS) structure modified with the enzyme acetoin reductase, also known as butane-2,3-diol dehydrogenase (Bacillus clausii DSM 8716T), is applied for acetoin detection in beer,

Efficient (3S)-Acetoin and (2S,3S)-2,3-Butanediol Production from meso-2,3-Butanediol Using Whole-Cell Biocatalysis

Molecules, 2018
(3S)-Acetoin and (2S,3S)-2,3-butanediol are important platform chemicals widely applied in the asymmetric synthesis of valuable chiral chemicals. However, their production by fermentative methods is difficult to perform.
