METABOLITE PRODUCTION BY LACTIC ACID BACTERIUM

摘要

It is provided a process for the isolation of a strain of a bacterium Lactococcus lactis lactis with increased 2,3- butanediol production capacity, the process comprising subjecting strain CML B4 to two consecutive rounds of mutagenesis. It is also provided a new strain of the bacterium Lactococcus lactis lactis, characterized by a high ability to produce 2,3-butanediol, obtainable by the process as defined above, and a method to produce such 2,3-butanediol by culturing the aforementioned bacterium under microaerobiosis.
