NGHIÊN CỨU NHÂN GIỐNG NẤM VÂN CHI (TRAMETES VESICOLOR) DẠNG DỊCH THỂ

The Turkey tail Trametes versicolor has been considered the major medicinal mushroom worldwide, mainly due to its traditional usage, polysaccharopeptides have been purified from this species, showing experimental immunomodulatory and anti-cancer effects. The growth of Trametes versicolor strain under liquid fermentation conditions was examined. The experiment results indicated that the turkey tail mushroom mycelium grew best on (2 gam Pepton + 2 gam yeast extract + 0,2 gam MgSO4.7H2O + 1gam KH2PO4 + 15gam glucose + 1,5 mg vitamin B1 + 1000ml distilled water) medium. On this medium, turkey tail mycelium was growing fast, mycelial dry weight is 35,2 g/ 1000ml, the highest number of mycelial pellet. Turkey tails mushroom mycelium grew best on in temperatures as 26 - 30 ° C. Different oxygen supply modes can significantly affect to the morphology and mycelia biomass, the optimal concentration of oxygen is 0,6 liters/ 1 liters liquid / minute. The suitable time to obtained the mycelium grew well at 72 - 84 hour.
