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

open access: yesBiotechnology 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

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 ...

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).

Bean‐to‐Bar Chocolate: An Integrative Framework Linking Terroir, Biochemistry, Processing, and Sensory Expression

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT The bean‐to‐bar movement, which emerged in the United States in 1996, represents a transformative approach to chocolate production and consumption by integrating craftsmanship, sustainability, and gastronomic authenticity. This study conducted a literature review using the narrative approach, as the object of investigation encompasses both ...

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
