Inhibition of aflatoxin accumulation by newly synthesized analogues of coumarine in Aspergillus flavus ATCC 26949

Sažetak
Inhibition of aflatoxin B1 and total aflatoxins (AFT) accumulation by newly synthesized analogues of coumarine was investigated in YES medium to determine the possible use of these compounds as a means of controlling aflatoxin accumulation. Experiments were carried out in a stationary culture at temperatures of 15, 25 and 35oC, respectively during 21 days. Mycelial dry weights were determined gravimetrically, and examined by thin layer chromatography and immunochemical technique. Concentrations of two investigated coumarine of 0.01 and 0.02 mmol/L, respectively stimulated mold growth and AFB1 and AFT accumulation, but concentrations higher than 0.05 mmo/L of these compounds, mold growth and aflatoxin accumulation partially inhibited. In experiments with 0.1 mmol/L of these compounds mold growth and aflatoxin accumulation were inhibited completely depending on the time and temperature of cultivation
