Abstract:
Culture medium of Pteurorus ostreatus were collected from mushroom production plant in Hengyang area and took back to the laboratory to deal.The strains，separated from the medium，were purified and identified by colony and microscopic morphology.Then mycelium of each one separated strains and P.ostreatus were inoculated on the same PDA flat to study the effects of isolated strains on the growth of P.ostreatus.The results showed that eight strains，numbered PoD1~PoD8 were isolated and identified by morphology，PoD1，PoD2 and PoD3 were Flavimonas sp.，Bacillus subtilis and Pseudomonas sp.respectively；PoD4 and PoD5 were Rhodolorula spp.，PoD6 was Schizosaccharomyces sp.；PoD7 and PoD8 were Neurospora sitophila and Aspergillus glaucus respectively.The results of confrontation inoculation showed that moulds had significant inhibition effect on the growth of P.ostreatus，then the bacteria had a certain inhibition effect，the last were yeasts.
