摘要
Ascospores from 25 strains of Byssochlamys were studied for their ability to resist heat treatment in a standard defined medium. Of these, 7 were able to survive heating at 90.degree. C for 25 min or longer, when initial numbers were frequently near 106/ml. Ascospores from 5 resistant strains suspended in the medium at pH 5.0 were usually more resistant than those at pH 3.6. Rapid heat inactivation occurred for 1 strain at pH 6.6. Nonlogarithmic heat death rate was observed in all strains tested. [Byssochlamys causes spoilage of canned fruits.].
