Strain-level variation in diacetyl production by Lactiplantibacillus plantarum reveals genetic drivers of flavor in fermented dairy

Journal of Dairy Science
: Strain-level diversity in aroma formation remains undercharacterized in Lactiplantibacillus plantarum, a key adjunct culture in dairy fermentation. We screened 351 isolates from traditional Chinese fermented foods for diacetyl production and identified

Oleuropein Transcriptionally Primes Lactobacillus plantarum to Interact With Plant Hosts

Frontiers in Microbiology, 2019
Oleuropein (OLE) is a secoiridoid unique to Oleaceae known to play a role in the plant–herbivore interaction. However, it is not clear how this molecule is induced to mediate plant responses to microbes and how microbes, in turn, withstand with OLE.

New acetoin reductases from Bacillus stearothermophilus: meso- and 2R,3R-butanediol as fermentation products

, 2011
The fermentation of sucrose with Bacillus stearothermophilus ATCC 2027 afforded 2R,3R- and meso-2,3-butanediol together with R-acetoin following the bacterial catabolic pathway.

Acetoin Synthesis Acquisition Favors Escherichia coli Growth at Low pH [PDF]

, 2014
Some members of the family Enterobacteriaceae ferment sugars via the mixed-acid fermentation pathway. This yields large amounts of acids, causing strong and sometimes even lethal acidification of the environment.

D-2,3-Butanediol Production Due to Heterologous Expression of an Acetoin Reductase in Clostridium acetobutylicum

, 2011
Acetoin reductase (ACR) catalyzes the conversion of acetoin to 2,3-butanediol. Under certain conditions Clostridium acetobutylicum ATCC 824 (and derived strains) generates both D- and L-stereoisomers of acetoin, but due to the lack of an ACR enzyme, does

Isolated tumoral pyruvate dehydrogenase can synthesize acetoin which inhibits pyruvate oxidation as well as other aldehydes.

, 1987
International audienceOxidation of 1 mM pyruvate by Ehrlich and AS30-D tumor mitochondria is inhibited by acetoin, an unusual and important metabolite of pyruvate utilization by cancer cells, by acetaldehyde, methylglyoxal and excess pyruvate.

Screening, Safety Assessment, and Process Optimization of Lactic Acid Bacteria from Traditional Yak Yogurt as Adjunct Cultures

Microorganisms
Cheese ripening is slow and costly, driving interest in accelerating maturation. This study aimed to isolate a safe, efficient adjunct starter from traditional Sichuan yak yoghurt, a niche rich in stress-adapted lactic acid bacteria.
