Notes:
Growth and fumitremorgin production by a heat-resistant mold, Neosartorya fischeri, in atmospheres containing 0.0095-20.9% O2 were studied over a 38-day period. The mold was cultured on Czapek Yeast Autolysate agar adjusted to pH 3.5 and 7.0 and incubated at 25°C in darkness. Colonies were examined and extracts were analyzed for fumitremorgin content using high performance liquid chromatography. Growth occurred at O2 levels as low as 0.10% but not at 0.0095%. Growth was always associated with production of verruculogen and fumitremorgins A and C. Production of these fumitremorgins was essentially the same in atmospheres containing 3.0 and 20.9% O2, but was greatly reduced in an atmosphere containing 1.0 and 0.10% O2. Fumitremorgin production was not significantly different at pH 3.5 and 7.0
