【中文摘要】 经研究,筛选所获香菇菌株能适应液体培养环境,48h前为其调整期,48～144h处于增殖生长期;发酵培养96～120h,生物量即达30g/1OOmL(鲜重);提制的香菇营养液,氨基酸含量达1851,49mg/1OOmL,多糖含量为14.75mg/100mL;提制的香菇多糖粉是一种甘露糖肽,行较强的免疫活性,得率在0.3％左右。

【英文摘要】 It was identified that the Lentinula edodes strain selected in our study could adapt to submerged cul-ture conditions, that its adjustment period and multiplication period were 0 - 48h and 48-144h resp, that the biomass reached 30g/100mL (fresh weight) only 96 - 120h after fermentation culture, and that the content of ammo acid and polysaccharide in thc extracted nutrient solution was 1851. 49 mg/ 100ml, and 14. 75mg/mL resp. . While the polysacrllaridc powder extracted from the mash was proved to be a kind of mannose peptide with strong immune activity and a productivity of about 0.3%.
