| two new aflatoxin producing species, and an overview of aspergillus section flavi. | aspergillus subgenus circumdati section flavi includes species with usually biseriate conidial heads, in shades of yellow-green to brown, and dark sclerotia. several species assigned to this section are either important mycotoxin producers including aflatoxins, cyclopiazonic acid, ochratoxins and kojic acid, or are used in oriental food fermentation processes and as hosts for heterologous gene expression. a polyphasic approach was applied using morphological characters, extrolite data and partia ... | 2011 | 21892243 |
| the first report of a. novoparasiticus, a. arachidicola and a. pseudocaelatus in brazilian corn kernels. | maize is one of the most important commercial crops cultivated throughout the world, mostly in tropical and subtropical countries. it is highly susceptible to mycotoxins, toxic secondary metabolites produced by fungi. in this study, we assessed freshly harvested corn produced in brazil for aflatoxin contamination and the presence of aspergillus. b type aflatoxins (afb1+afb2) were detected in 56% of 16 grain samples, while g type aflatoxins (afg1+afg2) were detected in 25%. of the total number of ... | 2017 | 27978505 |
