Distribution and aflatoxin productivity of the atyptical strains of Aspergillus flavus isolated from soils in Thailand

Abstract

The distribution and aflatoxin productivity of atypical sclerotigenic strains of Aspergillus flavus isolated from soils in Thailand were investigated. Out of the 27 soil samples from 8 provinces, 9 samples were detectable for the strains. Among these 9 samples, 7 were colleted from the maize fields in two northern provinces: Chiang Rai and Chiang Mai. All of 11 isolated of the strains tested producted aflatoxins, while half of 24 isolates of the typical strains produced them.
