摘要：

Lactobacillus casei subsp. casei 2206 exhibited much lower levels of diacetyl reductase activity than Citr+ Lactococcus lactis subsp. lactis 3022 but two-, three-, and more than eightfold-higher levels of diacetyl synthase, lactate dehydrogenase, and NADH oxidase activities, respectively. A requirement for metal ions by the diacetyl synthases in both species was observed. The extracts of strain 2206 but not strain 3022 produced more diacetyl from pyruvate when the reaction for diacetyl synthase was aerated than when it was conducted statically.
