摘要
以菌落直径为测量指标,采用单因素试验来筛选兰坪虫草菌株Clan-7菌丝生长培养基的碳源和氮源,并分析了不同温度和pH值对其菌丝生长的影响;结果表明,最适合Clan-7菌丝生长的碳源为麦芽糖,氮源为黄豆粉;最适合菌丝生长的培养条件为温度20℃、pH=6～6.5。
Colony diameter was used as measurement index to screen carbon source and nitrogensource of mycelial growth medium for Ophiocordyceps lanpingensis strain Clan-7 with single factorexperiment. The effects of different temperature and pH value on its mycelial growth were alsoanalyzed. The result showed that the optimum carbon source for mycelial growth of Clan-7 wasmaltose and the optimum nitrogen source was soybean meal. The optimum culture condition wastemperature being 20℃ and pH=6-6.5.
