PROCESS FOR PREPARING A CEPHALOSPORIN BY FERMENTATION

摘要

Ceohalosporin is produced by fermn. with Rhodosporidium toruloid CBS-349. Thus, A, cryzpgenim IMI 237183 was inoculated into a medium contg. CLS, lactoes, glucose, methionine, phenylacetylethanolamine, CaCO3, urea, (NH4)2SO4, corn oil, and acetly esterase, which was produced by fermn. with R. to ruloid CBS-349, and cultured at 250≦̸C for 5 days with aeration to give cephalosporin C.
