摘要
以菌丝体生物量为指标,对大球盖菇液体菌种培养基中碳氮营养源进行了优化。结果表明,最佳液体发酵培养基配方为:葡萄糖30 g/L,酵母膏4 g/L,KH2PO42 g/L,MgSO41 g/L;培养条件为初始pH值6.5,25℃培养6 d。栽培试验结果表明,接种液体菌种的栽培袋的发菌时间平均比接种固体菌种缩短17 d。
Based on the indexes of mycelial bioyields （dry weight）, effects of carbonaceous compounds and nitrogenous substances on the growth of Stropharia rugoso annulata were researched. Results suggested that the optimum compositions of liquid fermentation medium should include glucose（30 g/L）, yeasts exact （4 g/L）, KH2 PO4 （2 g/L）, MgSO4 （1 g/L）. The culture conditions were initial pH 6.5,culture temperature 25℃, culture time 6 days. Afterward,the cultivation was designed to contrast the liquid spawn and the solid spawn. Results showed that the samples which were inoculated liquid spawns overgrew 17 days earlier than those of solid spawns.
