  • Title: Metabolic behaviour of aflatoxin producing strain and non-toxigenic strain of Aspergillus flavus to different sources of nitrogen and glucose concentration.
    Author: Thapar GS.
    Journal: Mycopathologia; 1988 Apr; 102(1):9-12. PubMed ID: 3138542.
    Abstract:
    The effect of different nitrogen sources and varying glucose concentration on aflatoxin production by a toxigenic and non-toxigenic strain of Aspergillus flavus was studied. Greatest production (3.8 ppm) of aflatoxin B1 was produced in a synthetic medium when casamino acids were supplied as the nitrogen source. Optimum sugar concentration for aflatoxin B1 production ranged between 3 and 10 g/100 ml. There was no appreciable difference in the metabolic behaviour between toxigenic and non-toxigenic strains of A. flavus when dry mycelial weight, total proteins, non-protein nitrogen and reducing sugar were the criteria.
