平菇液体种子培养基优化

The Optimiztion of Cultural Medium of Liquid Strain of Pleurotus ostreatus FL_(10)

对平菇FL10液体种子的培养基进行了优化,结果表明,平菇菌丝在玉米粉培养基中生长最好;酵母膏为适宜氮源;C/N比为50∶1时菌丝生长最佳;KH2PO4和维生素B1对菌丝生长有促进作用。最适培养基组成为:玉米粉30 g/L,酵母膏3 g/L,KH2PO41.5 g/L,MgSO4.7H2O 1 g/L和维生素B10.01 g/L。

The appropriate liquid strain cultural medium of P. ostreatus FL10 was optimized. The results showed that corn meal was suitable for the growth of P. ostreatus. A satisfactory nitrogen source was yeast extract. C/N ratio of 50：1 was suitable for the growth. It was also found that KH2PO4 and vitamin B1 could greatly stimulate the growth. The optimum formula for the myeelial growth of P. ostreatus was as foUows：30 g/ L corn meal,3 g/L yeast extract,1.5 g/LKH2PO4 ,1.0 g/LMgSO4 · 7H2O and 0. 01 g/L vitamin B1.
