Strain improvement studies on production of cephalosporin C from Acremonium chrysogenum ATCC 48272. Hindustan Antibiotics Bulletin. 2003 Feb-2004 Nov; 45-46(1-4): 11-5http://imsear.searo.who.int/handle/123456789/2238Strain development for antibiotic production has been an essential prerequistie for efficient production process. Studies were carried out to produce high antibiotic yield strain by using UV and N-methyl-N1-nitro-nitrosoguanidine (NTG) as mutagens. A superior mutant (PNTG-22) with a productivity of 2.4 time (810-1995 microg/ml higher than, the parent strain was produced.engAcremonium --geneticsCephalosporins --biosynthesisMutationSpectrophotometry, UltravioletSpores, Fungal --chemistryJournal Article
