ABSTRACT:
A process for preparing a 7-aminocephalosporanic acid compound which comprises treating a cephalosporin C compound with an enzyme-producing microorganism belonging to the genus Pseudomonas or a material obtained by subjecting the microorganism to chemical and/or physical treatment. A direct hydrolysis of the cephalosporin C compound into the 7-aminocephalosporanic acid compound and D-.alpha.-aminoadipic acid can be attained by the microorganism or material.
