Abstract

Studies were carried out on bacteria, which usually infect spawns and culture plates of Psathyrella atroumbonata check for this species in other resources (Pegler) and Schizophyllum commune check for this species in other resources (Fr. Ex. Fr.), two Nigerian edible mushrooms. During the vegetative propagation of these higher fungi, six different bacteria species were isolated and characterized from 14 day old spawns and mycelial ramified PDA culture plates. These bacteria include Bacillus licheniformis, Bacillus subtilis, Leuconostoc mesenteroides, Pseudomonas aeruginosa, Bacillus cereus and Staphylococcus aureus. The average bacteria count was 1.0 x 106 cfu/ml and these bacteria grew within pH range of 5.0 and 9.0. the optimum temperature range of growth lied between 30°C and 37°C. The significance of these findings to the cultivation of P. atroumbonata and S. commune in Nigeria were discussed.
