title: Laboratory-scale production of acetoin plus diacetyl by Enterobacter cloacae ATCC 27613.
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 (240 rpm) at 28-30 degrees C for 48 hr. Recovery of pure diacetyl was 85% of the total acetoin plus diacetyl.
