【中文摘要】 本研究对不同ｐＨ条件下和相同ｐＨ条件下灰树花发酵液及菌丝生长情况进行了测定。结果表明，灰树花发酵液的初始酸碱度以ｐＨ８为宜，终止ｐＨ３保担菌丝最适宜生长的ｐＨ为５左右。无论初始ｐＨ相同或不同，发酵液的ｐＨ随着时间的延长和菌丝的生长而逐渐下降，其下降的趋势为快雎隹飑雎。
【英文摘要】 The mycelia of Grifora frondosa and pH value of fermented solution were measured at different pH value and the same pH valus. The results showed that optimal primary pH value was 8, the final pH value was 35 for Grifora frondosa fermentation. The optimal pH value for mycelia growth was 5. The pH value of fermented solution declined gradually as the culture time elongated and the mycelia growed whether the primary pH value was the same or not. The declined trend was quickslowquickslow.
