Toxigenic potential of Aspergillus flavus tested in different culture conditions Potencial toxigênico de Aspergillus flavus testado em diferentes meios e condições

Aflatoxins are compounds with a hepatotoxic, carcinogenic, and teratogenic potential that can affect either humans or animals (MOSS, 2002; SALEEMULLAH et al., 2006; D’MELLO; MACDONALD, 2002). According to an IARC estimates (INTERNATIONAL..., 2002), aflatoxins can be considered carcinogenic to humans (group I). The conditions that promote mycotoxin production are usually more restricted than those for mould growth (GUITAKOU et al., 2006; BRESLER et al., 1995). Mycotoxin production depends on fungal species, substrate, temperature of the media, pH, relative humidity, and storage or incubation time (BRAGULAT et al., 2001; FILTENBORG et al., 1983; SMEDSGAARD, 1997; BELLI et al., 2004; WEELER et al., 1991).
