Enhancement of Echinocandin B Production by a UV- and Microwave-Induced Mutant of Aspergillus nidulans with Precursor- and Biotin-Supplying Strategy.

Echinocandin B belongs to lipopeptide antifungal antibiotic bearing five types of direct precursor amino acids including proline, ornithine, tyrosine, threonine, and leucine. The objective of this study is to screen over-producing mutant in order to improve echinocandin B production; a stable mutant Aspergillus nidulans ZJB12073, which can use fructose as… (More)
