Effects of different brewing techniques on the contents of acetoin and ligustrazine in Shanxi aged vinegar [PDF]

Zhongguo niangzao
In order to improve the production process and enhance the quality of aged vinegar, using Cupei as the research object, the changes in alcohol content, total acid, acetoin and ligustrazine were examined during traditional and mechanical acetic acid ...

Transcription in the acetoin catabolic pathway is regulated by AcoR and CcpA in Bacillus thuringiensis.

Microbiology Research, 2020
Acetoin (3-hydroxy-2-butanone) is an important physiological metabolic product in many microorganisms. Acetoin breakdown is catalyzed by the acetoin dehydrogenase enzyme system (AoDH ES), which is encoded by acoABCL operon.

Simultaneous biosynthesis of (R)-acetoin and ethylene glycol from D-xylose through in vitro metabolic engineering

Metabolic Engineering Communications, 2018
(R)-acetoin is a four-carbon platform compound used as the precursor for synthesizing novel optically active materials. Ethylene glycol (EG) is a large-volume two-carbon commodity chemical used as the anti-freezing agent and building-block molecule for ...

Formate hydrogen lyase mediates stationary-phase deacidification and increases survival during sugar fermentation in acetoin-producing enterobacteria

Frontiers in Microbiology, 2015
Two fermentation types exist in the Enterobacteriaceae family. Mixed-acid fermenters produce substantial amounts of lactate, formate, acetate and succinate, resulting in lethal medium acidification.

Stimulation of Fermentation in Yeasts by Acetoin and Oxygen

Nature, 1966
IN Warburg experiments with ‘resting’ cells, most yeasts show a Pasteur effect, that is, fermentation of glucose is inhibited under aerobic conditions. This effect is generally regarded as an inhibition of fermentation by respiration, for example, as a result of a lack of inorganic phosphate (Pi) or adenosine diphosphate (ADP)1,2.

Thermophilic fermentation of acetoin and 2,3-butanediol by a novel Geobacillus strain

Biotechnology for Biofuels, 2012
Background Acetoin and 2,3-butanediol are two important biorefinery platform chemicals. They are currently fermented below 40°C using mesophilic strains, but the processes often suffer from bacterial contamination. Results This work reports the isolation

Structure-Based Design of Acetolactate Synthase From Bacillus licheniformis Improved Protein Stability Under Acidic Conditions

Frontiers in Microbiology, 2020
Catabolic acetolactate synthase (cALS) plays a crucial role in the quality of liquor because of its ability to catalyze the synthesis of the endogenous precursor product α-acetolactate of the aromatic compound tetramethylpyrazine (TTMP) and acetoin ...

Acetolactate and Acetoin Synthesis in Ripening Peas [PDF]

Plant Physiology, 1964
The role of acetolactate as a precursor in valine biosynthesis was first indicated by the isotopic studies of Strassman et al. (18) and was subsequently supported by work on valine-less mutants of Escherichia coli (21, 22) and Neurospora, crassa (24).

Enantiomeric differentiation of three key volatile compounds in three different palm wines (Elaeis guineensis, Borassus flabellifer and Nypa fruticans)

CyTA - Journal of Food, 2018
The contents and enantiomeric distributions of three chiral compounds, linalool, phenylethanol and acetoin, were investigated in three different palm wines (i.e. Elaeis guineensis, Borassus flabellifer, and Nypa fruticans). While N.
