Metabolism of acetoin in Clostridium acetobutylicum ATCC 824
, 1999 Acetoin is a product of fermentation by C. acetobutylicum, and a component of several natural and artificial flavors, including butter flavor. Acetolactate synthase (ALS) catalyzes the production of acetolactate from pyruvate.

Metabolic Engineering of Bacillus methanolicus MGA3 for Production of Acetoin
, 2018 Being a pure, inexpensive, non-food chemical that can be sustainably produced, methanol has attracted great interest as a carbon feedstock for microbial production of commodity/specialty chemicals. In this thesis, methanol-based production of acetoin was

Biochemical evidence for multiple acetoin-forming enzymes in cultured plant cells
, 1999 Acetoin (3-hydroxy-2-butanon) production was investigated in extracts from suspension cultured cells of carrot, tobacco, maize and rice. Crude extracts were able to catalyze acetoin synthesis from pyruvate and/or acetaldehyde at rates ranging from 0.02 ...

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 ...

Elektrofermentation von Acetoin
, 2018 Electrode-assisted fermentation is a new strategy in anaerobic biotechnology. It can be used for reactions in which the average oxidation state of the end product is higher than the substrate.

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

, 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 ...
