CO-CULTIVATION OF <i>PLEUROTUS OSTREATUS </i>(JACQ.) P. KUMM. WITH YEASTS
Co-cultivation of Pleurotus ostreatus with eight yeast species were investigated on water agar. Special mycelial structures to contact with yeast cells were found in such cultures: nipple-like appendages and coralloid hyphae. Three out of eight species, Hanseniaspora uvarum, Rhodotorula minuta, and Saccharomyces cerevisiae were identified as trophic preferendum for P. ostreatus. These three yeast species were used for mushroom cultivation on sunflower seed's peel. The biomass of fruiting bodies increased on 52,8-75,7% with the H. uvarum and S. cerevisiae suspension presence in the substrate.
