The effect of temperature on spore germination and growth of Mucor miehei in submerged culture

Abstract

Mucor miehei was grown in submerged culture at 30, 37, 40, 42.5, 45, and 48 °C. Maximum growth yield occurred at 48 °C.The effect of temperature on spore germination was examined. No spores germinated within 8 h at temperatures below 36.7 °C or above 53.5 °C. The optimum temperature for spore germination was 45 °C.Growth occurred at the marginal temperatures of 20 °C and 25 °C only when the spores were pre-germinated at 37 °C
