Effect of alsD deletion and overexpression of nox and alsS on diacetyl and acetoin production by Lacticaseibacillus casei during milk fermentation

Journal of Dairy Science, 2022
: Diacetyl and acetoin are key aroma components of fermented milk but are produced in low concentrations by starter cultures. In this study, we expressed NADH oxidase, acetolactate synthase, and inactivated acetolactate decarboxylase in ...

On the Formation of Acetoin by Acetobacter [PDF]

Journal of General Microbiology, 1959
SUMMARY: The formation of acetoin was studied with 44 strains of the genus Acetobacter, when growing on a medium containing DL-lactate as the main carbon source. Most of the strains produced only limited amounts of acetoin. However, strains of the species A.
