Electrophoretic variation in esterases in 3 wild-type and respective mutant strains of Aspergillus flavus. 1977

H M de Souza, and I R Baracho, and C L Messias, and J L de Azevedo

Wild-type strains and auxotrophic mutants of Aspergillus flavus, differing regarding aflatoxin production, were tested for esterases isozymes. Esterases variation was found in all strains used, and a possible correlation between the pattern of esterase bands and aflatoxin production is suggested.
