Biosynthesis of dehydroaltenusin by talaromyces flavus

Abstract
A new metabolite, identical with dehydroaltenusin was isolated from a strain Talaromyces flavus B 5 which was selected from parental strain 51 C/I. Metabolite inhibited the growth of wooddamaging fungi, especially Ciadosporium sphaerospermum and P388 leukemid cells.
