The composition of volatile organic compounds (VOC) released by the entomopathogenic fungus Beauveria bassiana (Hyphomycete: Deuteromycotina) utilizing two different carbon sources was investigated. Analyses were performed by solid-phase microextraction (SPME) coupled to capillary gas chromatography (CGC) and CGC-mass spectrometry (MS). Major components in glucose-grown cultures were diisopropyl naphthalenes, ethanol, and sesquiterpenes. Alkane-grown fungal VOC switched to a fingerprint with prevalence of n-decane. This is the first report on the volatiles released by entomopathogenic fungi.
研究了利用两种不同碳源的昆虫病原真菌球孢白僵菌(半知菌亚门:丝孢纲)释放的挥发性有机化合物(VOC)的组成。采用固相微萃取(SPME)结合毛细管气相色谱(CGC)和CGC-质谱(MS)进行分析。在以葡萄糖为培养基生长的培养物中,主要成分是二异丙基萘、乙醇和倍半萜。以烷烃为培养基生长的真菌VOC转变为以正癸烷为主的指纹图谱。这是关于昆虫病原真菌释放挥发性物质的首次报道。
