Kinetics of ochratoxin A production was examined in a number of ochratoxin producing isolates representing different sections of the Aspergillus genus. Both weak and high ochratoxin producers were tested using immunochemical or high-performance liquid chromatograhic methods. All isolates were found to produce the highest amounts of ochratoxin A after 7-10 days of incubation. Ochratoxin production varied between 30 - 5×105 ng ml-1 among the Aspergillus isolates tested. The A. albertensis and A. melleus isolates examined were found to produce ochratoxin A constitutively. A. albertensis produced the highest amounts of ochratoxin A at 30°C after 7 days' incubation in YES liquid medium. Ergosterol content and ochratoxin production of A. albertensis cultures were in good correlation.
