中文摘要：
以孢子粉含孢量、含水量及活孢率为质量指标，以单位质量基质产孢数为产量指标，对大米固态发酵生产球孢白僵菌高孢粉的发酵条件进行优化。结果表明，发酵条件为：接种量15％（v／w），初始基质含水量40％，培养温度25℃，环境湿度前4d为100％，中间3d为80％，后3d为60％，培养10d。此条件下，孢子粉含孢量达到（1．93±0．08）×10^11g^-1，含水量为（10．4±1．1）％，活孢率为（97．3±2．1）％，单位质量大米孢子粉产量达到（41．6±2．0）×10^11kg^-1。
英文摘要：
The solid fermentation for Beauveria bassiana production by rice was investigated. Experimental results indicated that the optimal fermentation conditions were as follows, inoculation volume 15 % （v/w）, initial water content of substrate 40%, fermentation temperature 25℃, relative humidity in the first 4d 100%, in the latter 3d 80%, and in the last 3d 60%. The high quality of the conidia powder was featured a purity of （1.93±0.08））〈 10^11 conidia/g . The water content was 10.4%±1.1%. And the viability was 97.3%±2.1%. Conidial yield reached （41.6±2）×10^11/kg rice.
