Identification by PCR of Fusarium culmorum strains producing large and small amounts of deoxynivalenol.

abstract：:Melanin is a pigment produced by organisms throughout all domains of life. Due to its unique physicochemical properties, biocompatibility, and biostability, there has been an increasing interest in the use of melanin for broad applications. In the vast majority of studies, melanin has been either chemically synthesize...
