Abstract

Aspergillus flavus species are, quantitatively, the highest aflatoxin producer strains Known. The morphological characteristics and enzymatic capability of 137 strains of A. flavus are being investigated in order to determine the existence of any attribute leading to the differentiation of the toxigenic strains from the non toxigenic ones. Toxigenic strains present a higher amount of sclerotia and proteolitic activity greater than the non toxigenic strains. However, the activity of both groups of strains are generally similar without significative differences between them. Only the urease activity differs significatively in these groups. There is no bibliographical reference that could explain the importance of that activity, but it could be attributed to some type of metabolic regulation in the biosynthesis pathway of the aflatoxin.MORPHOLOGICAL AND ENZIMATIC DIFFERENCES BETWEEN STRAINS OF ASPERGILLUS FLAVUS, PRODUCER AND NO PRODUCER OF AFLATOXINS
