Sažetak
Mycelial growth and afl atoxin B1 accumulation by toxigenous mould Aspergillus flavus were inhibited by dehydroacetic acid and its newly
synthesized analogues, 4-hydroxy-3-(p-toluoyl)-6-(p-tolil)-2H-yrane-2-one (DHT) and 5-Bromo-4-hydroxy-3-(p-toluoyl)-6-(p-tolil)-2Hpyrane-2-one (BrDHT) during the growth of investigated mould on solid substrate (soy-beans). Experiments were carried out in a stationary culture at 20 0C and 30 0C, respectively, during 21 days. Mycelial growth (biomass dry weight) was determined by measuring the chitin content and concentration of afl atoxin B1 (AFB1) was quantitated by HPLC. Concentrations of DHA and
DHT of 0.1 and 0.2 μg x g-1 of substrate were stimulated, but concentrations higher than 0.5 μg x g-1 of these compounds, mould growth and AFB1 accumulation partially inhibited. In experiments with 0.2 μg x g-1 of BrDHT mould growth and AFB1 accumulation were inhibited completely depending on the time and temperature of cultivation.
