Acetoin Promotes Plant Growth and Alleviates Saline Stress by Activating Metabolic Pathways in Lettuce Seedlings

Plants
Acetoin is a volatile organic compound, which is a class of metabolites produced by plant growth-promoting rhizobacteria. The mechanisms underlying plant growth promotion by acetoin and its potential to induce saline stress tolerance in plants are poorly

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 ...

Impact of Inoculation Strategy on Dendrobium nobile Lindl. Rice Wine Quality Through the Use of Saccharomyces cerevisiae FBKL2.8022 and Wickerhamomyces anomalus FBKL2.8023

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
This graphical abstract compares four fermentation strategies for D. nobile rice wine: simultaneous inoculation without D. nobile (SW), simultaneous inoculation with D. nobile (DnSW), sequential inoculation without D. nobile (WS), and sequential inoculation with D. nobile (DnWS). Simultaneous inoculation (SW/DnSW) enhanced volatile compound content (up

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.
