摘要: The genetics of s-lactam-producing fungi are fundamentally interesting and a key feature in the development industrial microbial genetics. In this review, I will focus mainly on three organisms, Aspergillus nidulans, Penicillium chrysogenum,and Cephalosporium acremonium since these have been most extensively studied from genetical point view. adhere to narrow definition genetics, namely studies genetic recombination.
