Properties of a diacetyl (acetoin) reductase from Bacillus stearothermophilus

, 1996
The cells of Bacillus stearothermophilus contain an NADH-dependent diacetyl (acetoin) reductase. The enzyme was easily purified to homogeinity, partially cahracterized, and found to be composed of two subunits with thw same molecular weight.

Effect of myrtle aromatization on chemical profile, sensory perception, and bioactivity of white wine vinegar

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Background Vinegar is a popular sour condiment rich in nutrients and bioactive components. Individual sour responsiveness greatly affects vinegar acceptance and diet consumption. In this study, the effect of aromatization with myrtle (Myrtus communis), a health‐beneficial Mediterranean aromatic plant, on the chemical composition, sensory ...

Biochemical evidence for multiple acetoin-forming enzymes in cultured plant cells

, 1999
Acetoin (3-hydroxy-2-butanon) production was investigated in extracts from suspension cultured cells of carrot, tobacco, maize and rice. Crude extracts were able to catalyze acetoin synthesis from pyruvate and/or acetaldehyde at rates ranging from 0.02 ...
