• Bacillus
  • Herein, we de- scribe the synthesis of (S)-phenylacetyl carbinol products with extended reaction scope employing the readily available wild-type ThDP-dependent enzyme acetoin :dichlorophenolindophenol oxidore- ductase (Ao:DCPIP OR) from Bacillus lichenifor- mis. (unife.it)
  • production
  • Owing to its neutral nature, production and excretion of acetoin during exponential growth prevents overacidification of the cytoplasm and the surrounding medium that would result from accumulation of acidic metabolic products, such as acetic acid and citric acid. (wikipedia.org)
  • The Voges-Proskauer test is a commonly used microbiological test for acetoin production. (wikipedia.org)
  • typically add
  • Because of this, manufacturers of partially hydrogenated oils typically add artificial butter flavor - acetoin and diacetyl - (along with beta carotene for the yellow color) to the final product, which would otherwise be tasteless. (wikipedia.org)
  • Because of this, manufacturers of artificial butter flavoring , margarines or similar oil -based products typically add diacetyl and acetoin (along with beta-carotene for the yellow color) to make the final product butter-flavored, because it would otherwise be relatively tasteless.

  • form
  • The form produced by bacteria is (R)-acetoin. (wikipedia.org)
  • Together with the acetylpolyamine amidohydrolases and the acetoin utilization proteins, the histone deacetylases form an ancient protein superfamily known as the histone deacetylase superfamily. (wikipedia.org)
  • culture
  • Once superior carbon sources are exhausted, and the culture enters stationary phase, acetoin can be used to maintain the culture density. (wikipedia.org)
