Abstract: VASUN PETCHARAT, University of the Philippines at Los Banos September, 1988. Microflora Associated With Outdoor Cultivation Of Volvariella, volvacea (Bull. Ex. Fr.) Sing. Professor: Dr. Tricita H. Quimio Forty-five samples of rice straw were collected from straw mushroom s during outdoor cultivation of Volvariella, volvacea . These were used isolate bacteria, actinomycetes and fungi by the dilution plate technique both at room temperature (28-32°C) and at 50°C. Fifty-five species (433 isolates, 37 genera) of fungi, three hundred and seventy-six isolates of unidentified bacteria and ninety-four gates of filamentous actinomycetes were collected. The percentage frequency of occurrence of each identified fungus was calculated at various stages of bedding. Verticillium sp. was most dominant at the -zing of bedding while AopeAgiau6 4umigatm was most common after 77esting. Relative cellulolytic activity of each of the fungus was measured and thirteen species of mesophilic and five species of thermophilic fungi showed strong cellulolytic activity Volvariella, volvacea mycelium were grow in dual cultures with each hated organism and in media supplemented with culture filtrate of selected organisms to observe antagonistic and/or enhancing effects. Thermoactinomycete isolate TA-1 promoted growth of mushroom mycelium 'ably by producing come metabolite secreted into the medium. Changes in the population of each group of microorganism, pH, moisture, and temperature within the straw mushroom were investigated throughout bedding time. The pH increased very fast during the first and second days of bedding, after which there was a slight change, while the moisture content decreased towards the end of the bedding time. The general pattern found in this study was an increase in temperature during bedding time, stimulating growth of thermophiles.
