MUSHROOM STRAINS ABLE TO GROW AT HIGH-TEMPERATURES AND LOW PH VALUES

Seven strains of edible mushrooms were studied with regard to mycelial growth on different growth media and culture conditions. Medium WDA ( wheat/dextrose/agar) promoted higher rates of mycelial growth for all the mushrooms investigated. The majority of the strains presented high er growth rates at 30 degrees C, but only Lentinus edodes kept maximum rates at low pH (pH 4.0), followed by rugosoannulata and Stropharia P leurotus ostreatus (pH 5.0). Absence of light favoured rapid mycelium development in all the strains tested.
