چکیده
The filamentous fungus Acremonium chrysogenum is the industrial producer of the β-lactam antibiotic cephalosporin C. Here, we present the genome sequence of strain ATCC 11550, which contains genes for 8,901 proteins, 127 tRNAs, and 22 rRNAs. Genome annotation led to the prediction of 42 gene clusters for secondary metabolites.

متن کاملProcess strategies for cephalosporin C fermentation
Cephalosporin C (CPC), a β-lactam antibiotic, is starting molecule for industrial production of semi synthetic cephalosporins. CPC fermentation has been carried out in Air Lift Reactor (indigenously made up of borosilicate glass) in different fermentation modes i.e., batch and fed batch modes using a mold Acremonium chrysogenum (synn. Cephalosporium acremonium). A definite correlation exists be...
