摘要:本文探討了靈芝(Ganoderma lucidum)菌絲原生質(zhì)體的制備及再生的條件。實(shí)驗(yàn)結(jié)果表明:采用MYG為靈芝菌絲培養(yǎng)基,2%真菌溶壁酶(Lywallzyme)作脫壁酶,0.6mol/L甘露醇作滲透壓穩(wěn)定劑;對(duì)培養(yǎng)6d的靈芝菌絲在30℃下進(jìn)行酶解,酶解時(shí)間4-6h,可產(chǎn)生約3.0×106個(gè)/mL(0.1g菌絲)原生質(zhì)體,并在添加靈芝子實(shí)體浸出汁的雙層培養(yǎng)基上實(shí)現(xiàn)了靈芝菌絲原生質(zhì)體的再生。

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.
Key words:Mycelia of Ganoderma lucidum;Protoplasts
