【中文摘要】 研究了不同酶種類、酶濃度、酶解溫度和時間、滲透壓穩(wěn)定劑、pH值及菌齡等因素對云芝原生質(zhì)體制備以及不同再生培養(yǎng)基對云芝原生質(zhì)體再生的影響。結(jié)果表明,菌齡3d的云芝菌絲體用3%溶壁酶,以pH5.5,0.4mol/L的KCl為穩(wěn)定劑,30℃酶解5h獲得的原生質(zhì)體產(chǎn)量最高;用RM1再生培養(yǎng)基培養(yǎng),原生質(zhì)體再生率最高。
【英文摘要】 We have examined the effects of selected parameters(nature and concentration of lytic enzyme,exposure time,temperature,nature,concentration and pH of osmotic stabilizer,mycelial age) on Coriolus versicolor protoplast production.Highest protoplast yields were obtained from 3-day-old mycelium after treatment with 3%(w/v) lywallzyme for 5 h at 30 ℃ using 0.4 mol/L KCl(pH 5.5) as osmotic stabilizer.Of six media tested,highest mycelium regeneration rates were obtained on RM1 medium consisting of 20%(w/v) potato,1%(w/v) yeast,0.3%(w/v) KH2PO4,0.15%(w/v) MgSO4,0.003%(w/v) Vitamin B1,0.4 mol/L KCl and 3%(w/v) agar.
