アセトイン醗酵(燐酸塩の種類とその添加濃度の影響に就て)

抄録

Bacillus natto and Micrococcus ureae gave higher yields of acetoin from the glucose-peptone medium than the other 8 species of bacteria. Addition of phosphates to the cultivation media caused a remarkable increase in acetoin production. The media with phosphates gave acetoin yields twice as high as that without phosphates by Micrococcus ureae.
The Optimum concentration of ammonium phosphate [(NH₄)₂H•PO₄] added to be was 0.1% and the highest yield of acetoio in this experiment was 1323mg per 100 cc of the medium or 26.5% of consumed glucose.
