dc.description.abstract | The effect of water activity (0.92, 0.95, 0.965 and 0.98) and temperature (15 °C, 25 °C, 30 °C and 35 °C) on growth rate and ochratoxin A (OA) production by five strains of Aspergillus carbonarius and two strains of A. niger isolated from Australian vineyards was characterised on a synthetic grape juice medium. Maximum growth for A. carbonarius occurred at ca 0.965 a{w} and 30 °C, and for A. niger, at ca 0.98 a{w} and 35 °C. The optimum temperature for OA production was 15 °C and little was produced above 25 °C. The optimum a{w} for toxin production was 0.95–0.98 for A. carbonarius and 0.95 for A. niger. Toxin was produced in young colonies after and, typically, did not continue to accumulate the entire surface area of the plate was colonised. Rather, the amount decreased as colonies aged. Trends for growth and OA production were similar among Australian isolates and those from European grapes, as reported in the literature. | - |
