Abstract:
mutant (UCN 7 17) of producing high yield Kojic acid was screened fr om Aspergillus flavus after treated with UV three times, ? ray of 60 Co one time and NTG four times, underoptimal conditions, the Kojic aci d production level reached up to 6 3% after 7 days, compared with original stains 0 926% The experiments showed that compound mutation using various mutagenic agents ca n alter the original stains sensitivity to mutagenic agents, increase mutation frequency and raise Kojic acid yield
