Effect of the raw extracts of Arthrinium strains (Hyphomycetes, Dematiaceae) on the growth of some deleterious fungi in poultry feed

In previous work the authors have shown that some species of the Arthrinium genus are characterized by being able to produce secondary metabolites wit h antibiotic activity. The aim of this study was to evaluate the effect of raw extracts of the growth of three different Arthrinium strains against As pergillus flavus, Aspergillus nidulans, fusarium moniliforme and Penicilliu m purpurogenum when they were present in poultry feed. The results showed t hat the extracts reduced the growth of Aspergillus flavus and Fusarium moni liforme but could not inhibit the development of Aspergillus nidulans. Only the raw extract of A. aureum inhibited the growth of Penicillium purpuroge num.
