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

open access: yesFrontiers 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 ...

Microbial Community Shifts and Plant Performance Improvements Driven by Bacillus firmus in Pampa Agroecosystems

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 3, June 2026.
The study shows that Bacillus firmus‐based bionematicides modulate soil microbiota and enhance soybean growth in the Pampa biome. Effects vary by location and time, with increased beneficial bacteria, reduced fungi, and decreased root nematode infestation. Overall, B.

Acetolactate and Acetoin Synthesis in Ripening Peas [PDF]

open access: yesPlant 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)

open access: yesCyTA - 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.

Stimulation of Fermentation in Yeasts by Acetoin and Oxygen

open access: yesNature, 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.

2,3-Butanediol and Acetoin Production from Enzymatic Hydrolysate of Ionic Liquid-pretreated Cellulose by Paenibacillus polymyxa

open access: yesBioResources, 2015
A safe microorganism (class 1), Paenibacillus polymyxa, was used for 2,3-butanediol and acetoin production, which could make the fermentation process cheaper and less complex.

Studies on Acetoin Fermentation

open access: yesJournal of the agricultural chemical society of Japan, 1953
l-Arabinose is the best carbon source in order to increase the yield of acetoin (acetylmethylcarbinol) by using B. natto, and d-glucose is the next. The highest yield of acetoin in this experiment was 562mg per 100cc of the medium, or 11.04% of consumed l-arabinose. On the other hand, the best nitrogen source is casein and the next is peptone. It seems

Dosage fluorimétrique de l'acétoïne dans le vin

open access: yesOENO One, 1994
Les auteurs proposent une technique analytique de dosage de l'acétoïne dans les vins après oxydation en diacétyle et condensation de ce dernier avec le diamineanisol-3,4. Le produit de condensation émet une forte fluorescence à partir de laquelle on peut
