STUDIES ON FERMENTATIVE CONDITIONS OF ECTOMYCORRHIZAL FUNGUS——SUILLUS GREVILLEI

Among the fermentative conditions of Suillus grevillei (Kl.) Sing., optimum initial pH was 4.5~5.6, optimum working volume of 500ml Erlenmeyer-flask was 150ml. It is no need for the growth of S. grevillei to be supplied with special carbon and nitrogen sources. Studylon liquid fermentation of S. grevillei in 14-litre fermentor demonstrated that S. grevillei had many advantages for producing commercial ectomycorrhizal inocula by industrial fermentation, such as short fermentation period, fast-growing rate and easy manipulation etc.
