Cloning of the bioA, bioD, bioF, bioC and bioH genes of Bacillus sphaericus, vectors and transformed cells, and process for the preparation of biotin

摘要

The invention relates especially to a DNA sequence corresponding to one of the following genes of the chain of biosynthesis of biotin in bacteria: bioA gene, bioD gene, bioF gene, bioC and bioH. …??Vectors comprising these sequences enable other microorganisms to be transformed in order to improve the biotin production.
