Study on the Thermotolerance of Pleurotus ostreatus Cell Engineering Strains

WANG Qian et al(College of Life Science,Hebei University,Baoding,Hebei 071002)  
19 cell engineering strains regenerated by protoplast from Pleurotus ostreatus were studied.When these strains were cultivated under 20,25,30 and 35 ℃,it was found out that six regenerative strains of protoplast grew faster than the original strain.Meanwhile,all the mycelium could grow at 20,25 and 30 ℃,but at 35 ℃ the mycelium could only bourgeon and was unable to grow.The result of further high-temperature-tolerant test showed that the strain P484 was more heat-resistant than other strains.This test proved the feasibility of breeding on edible fungi by the technology of protoplast regeneration.
