Abstract
A mutant strain having a glucose consumption rate is at most 1/4 that of wild type strains is provided. The mutant strain belongs to Escherichia, Bacillus, Pseudomonas, or Serratia; has a glucose consumption rate of at most one fourth that of the corresponding wild type strain, and the feedback repression by biotin is removed. Further, a process for producing biotins using this mutant strain is provided.
