Abstract

A method for transforming strain PF1022, which produces a cyclic depsipeptide (substance PF1022) and belongs to the order Agonomycetales of the class Hyphomycetes has been established by using a plasmid constructed with a promoter, a terminator, a marker gene and a target gene. When the strain PF1022 was transformed by this method, a gene encoding an enzyme, which is the target gene, was transduced into the host. As a result, the utilization of nutrients by the strain PF1022 was improved and, further, its cyclic depsipeptide productivity was also improved.
