Effects of temperature, pH and cultural media on the growth of Oyster mushroom (Pleurotus sp.) FH and PN20.

Abstract

Oyster mushrooms (Pleurotus sp.) are widely grown in Vietnam, because they not only provide clean food, and valuable pharmaceutical substances for medical use, but also play an important role in converting agricultural byproducts into valuable products, in biotreatment of xenobiotic compounds. The growth of mycelia is affected by temperature, pH, and culture medium. Therefore, the present study aimed at investigating the behaviour of oyster mushroom strains FH and PN20 under different media, temperature, and pH requirements for mycelial growth for the maintenance and production mushroom spawn with high efficiency. The results showed that the Potato dextrose agar (PDA) medium was the best culture for mycelial growth of FH and PN20 oyster mushrooms, followed by Sweet potato dextrose agar (SPDA) and Yam dextrose agar (YDA). The optimum culture temperature and pH for mycelium growth of FH and PN20 oyster mushrooms are 25°C, and 6.5, respectively.
