Abstract
A microorganism derived from a host microorganism capable of producing d-biotin by introducing a recombinant plasmid being incorporated with a biotin gene cloned from a microorganism of the genus Serratia capable of producing d-biotin and further integrating an exogenous biotin gene into the chromosome, and a process for preparing d-biotin which comprises cultivating the microorganism in a culture medium so that d-biotin is formed and accumulated in the culture medium and collecting the d-biotin. The microorganism of the invention has an extremely high productivity of d-biotin, and hence, d-biotin can be produced in a large amount by cultivating the microorganism of the invention.
