RECOMBINANT ESCHERICHIA COLI GENERATED D-LACTIC ACID, AND USE THEREOF

摘要

Provided is recombinant Escherichia coli comprising a mutated 1dhA gene. Disclosed are a use of the recombinant Escherichia coli in the preparation of D-lactic acid, and method of preparing the D-lactic acid by employing the recombinant Escherichia coli. In the method of preparing the D-lactic acid, fermentation can be conducted at a high temperature (42-50°C), and aqueous ammonia or sodium hydroxide can be used as a neutralizer during the fermentation.
