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

Protein Science, Volume 35, Issue 7, July 2026.Abstract FAD/NAD(P)H‐dependent dehydrogenases form a structurally conserved family of redox enzymes that participate in essential metabolic processes across parasites and higher organisms. Among them, trypanothione reductase (TR) is a key component of the redox metabolism of Leishmania species and represents an attractive target for antileishmanial ...

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).

Dosage fluorimétrique de l'acétoïne dans le vin
OENO 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

Studies on Acetoin Fermentation
Journal 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
