【中文摘要】 本文對靈芝ＴＷ的富鍺液體深層培養進行了研究，結果表明：靈芝ＴＷ富鍺能力較強，添加１００～３０００ｐｐｍ范圍內的Ｇｅ－１３２，在２６℃，１３０ｒｐｍ條件下培養９６小時富集鍺的范圍為０．４３７ｍｇ／ｇ～７．８２２ｍｇ／ｇ；Ｇｅ－１３２能促進ＴＷ靈芝菌絲體對還原糖的利用并提高菌絲體收率；Ｇｅ－１３２對ＴＷ靈芝發酵的ｐＨ值、發酵周期及蛋白質含量沒有影響，發酵終點ｐＨ值為４．５～４．９之間，發酵周期為９６小時，發酵終點蛋白質含量在３１．２％～３５．６％之間。
【英文摘要】 s This paper deals with the submerged fermentation of Ganoderma lucidum TW. The results show that TW's ability to absorb Ge-132 is very strong,adding Ge-132 from 100 to 3000ppm to the culture medium,under the condition of 26℃,130rpm and 96 hours,the strain absorbs germanium from 0.437mg/g～7.822mg/g;Ge-132 can improve the utilization rate of sugar and hyphal yield; Ge-132 has no effects on the fermentation cycle,pH value of the culture medium and protein content of the hyphae. The fermen-taton cycle is 96 hours,the pH value is between 4.5 and 4.9 and the protpin content is from 31.2%to 35.6%.
