Producing Conditions of Chlamydospore of Fusarium virguliforme sp.nov.in Liquid Culture
摘要
Abstract
The effects of culture medium,pH, temperature and oxygen on the chlamydospore production of Fusarium virguli-forme sp. Nov. Strain F-171 were studied by liquid culture method. The results showed that,the best liquid culture conditions for the chlamydospore production of the strain F-171 were,homogenized hyphae at 7500 r ? Min-1 for 2 min,filled 80 raL liquid culture of soybean stem or sprout juice in the 250 mL flask,and incubated at pH 6,25-30℃ and 120 r ? Min-1 shaking cu-litivation environment. Chlamydospore production curve in the best liquid culture conditions showed that the number of chlamydospore increased gradually with prolonging of the incubation time,reached the peak(3.15 ×105 spores ? mL-1) 10 days after incubation.关键词
