Cultural and toxigenic variability in Fusarium acuminatum

摘要: Twenty-five isolates of F. acuminatum from different sources and geographic origins were used for studying the cultural toxigenic characteristics species. The showed a large variability, features ranged slow-growing with carmine-red pigmentation relatively short 5-septate conidia to fast-growing yellow-brown long conidia. differences corresponded in production secondary metabolites. On basis their metabolite production, grouped into three categories: ( ) enniatin B and/or moniliformin producers (up 1000 2340 mg kg −1 , respectively); b T-2 toxin, HT-2 toxin neosolaniol 450, 40 20 c no-toxin producers. toxicity culture extract towards Artemia salina could usually be related occurrence above toxins.
