Abstract:
Conidial suspension was obtained from the Penicillium sp. DS9713a which could decompose PHB. Through screening a lot of mutants with the methods of transparent zones and flask culture, five strains were selected from starting strain treated with UV and their activity were higher than the original .The best mutant strain named DS9713a-CS01, it's enzyme activity was as 197.42% high as that of the original ,furthermore, the characters of crude enzyme were studied.
