Elimination of infection pressure of the bacteria pseudomonas tolaasii during the cultivation of pleurotus ostreatus

Anotace: Pleurotus spp. is in the top three of the most widely grown mushroom in the world's production. In connection with its intensive production in a conventional way, the risk of contamination with the most pathogens is avoided. The work deals with identification of the pathogen on the production crop of oyster mushroom, and with determining the optimal dilution of the commercially available disinfectant with 47 g/kg (4.7%) sodium hypochlorite to eliminate it. We found that the lethal dose of sodium hypochlorite for pathogen Pseudomonas tolaasii and for Pleurotus ostreatus is different, so we recommend using the disinfectant in specified dilutions even during the cultivation of oyster mushroom.
