Suppression of microbial metabolic pathways inhibits the generation of the human body odor component diacetyl by Staphylococcus spp. [PDF]

open access: yesPLoS ONE, 2014
Diacetyl (2,3-butanedione) is a key contributor to unpleasant odors emanating from the axillae, feet, and head regions. To investigate the mechanism of diacetyl generation on human skin, resident skin bacteria were tested for the ability to produce ...

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

open access: yesJournal 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 ...

Determina tion of diacetyl and 2,3-pentanedione in beer by gc/ms using solid-phase extraction columns [PDF]

open access: yesActa Periodica Technologica, 2002
A new GC/MS method for the determination of diacetyl and 2,3-pentanedione was investigated. Diacetyl and 2,3-pentanedione were derivatized with 1,2-diaminobenzene to form 2,3-dimetylquinoxaline and 2-ethyl-3-methylquinoxaline. respectively.
