摘要:本文探讨了灵芝(Ganoderma lucidum)菌丝原生质体的制备及再生的条件。实验结果表明:采用MYG为灵芝菌丝培养基,2%真菌溶壁酶(Lywallzyme)作脱壁酶,0.6mol/L甘露醇作渗透压稳定剂;对培养6d的灵芝菌丝在30℃下进行酶解,酶解时间4-6h,可产生约3.0×106个/mL(0.1g菌丝)原生质体,并在添加灵芝子实体浸出汁的双层培养基上实现了灵芝菌丝原生质体的再生。

Abstract:The conditions of protoplast formation and regeneration from the mycelia of Ganoderma lucidum were studied.Experimental results indicated that 3.0×106/mL protoplast of the mycelia of Ganoderma lucidum was obtained under optimal conditions,which are described as follows:Using 0.6mol/L mannitol as osmotic stabilizer;2% Lywallzyme as the enzyme digesting the cell wall;Using 6 days old MYG liquid cultures of the mycelia Ganoderma lucidum;at 30℃,enzyme digesting 4~6 hours.When incubated on two layer plates of agar,the protoplasts regenerated and formed new mycelia of Ganoderma lucidum.
