T. versicolor mushroom contains Polysaccharide - peptide (PSP) và Polysaccharide - Krestin (PSK) which have antibacterial effects, strengthen the immune system, inhibit cancer cells, anti-oxidation, etc. This study was conducted to obtain the mycelial growth and commercial cultivation conditions of T. versicolor. Six different formulations were set up to ascertain the optimal medium for primary propagation
the second propagation was cultured on Q5 rice paddy or cassava stick substrates supplemented with rice bran and corn bran in different rates. The efficiency of sawdust substrate and some added elements was also evaluated. The mycelium of T. versicolor grew well on a medium containing 2% glucose, 2% agar, 0.5% yeast extract and 0.5% peptone per liter. Q5 rice paddy supplemented with 0.5% CaCO3, 5% corn bran (or 5% rice bran) or cassava sticks supplemented with 0.5% CaCO3, 5% rice bran, 5% corn bran were suitable substrates for secondary propagation of T. versicolor mushroom. Acacia wood sawdust substrate with the addition of 5% rice bran, 5% corn bran and 1% CaCO3 was appropriate for growing T. versicolor mushrooms with a growth rate of mycelium reaching 6.64mm per day, fruit bodies' average size was 128.7 x 56.65 mm, yield reaches 163.41 g fresh mushrooms per 800 g of sufficiently moist materials, equivalent to 20.43% biological efficiency. The results could be used to cultivate and produce T. versicolor bodies with high productivity.
