Abstract

Conditions for the laboratory‐scale production of acetoin plus diacetyl by Enterobacter Cloacae ATCC 27613 were studied. Thirty‐five g acetoin plus diacetyl/50 g sucrose were obtained when fermentation was carried out in 2. 5 liter medium containing 12.5 g peptone and 12. 5 g yeast extract, at pH 7.0, in a 5 liter conical flask on a shaker (240rpm) at 28–30°C for 48 hr. Recovery of pure diacetyl was 85% of the total plus diacetyl.
