The present investigation was undertaken with the objectives to study the biochemical composition of Pleurotus florida grown on different straw substrates and activity of cellulolytic enzymes produced by Pleurotus florida under in vitro conditions. The results revealed that, the biochemical composition of P. florida raised on three straw substrates exhibited higher percentage of fat (2.33%) on soybean straw followed by wheat (1.74%) and paddy straw substrate (1.65%) on dry weight basis. The content of carbohydrate in P. florida was significantly higher when it was raised on wheat straw substrate (32.54%). Moisture (91.68-97.78%), ash (6.81-7.84%) and protein (18.30-20.0%) content of P. florida did not vary significantly with the different substrates used. The maximum activity of cellulase was observed in 20 and 16 days old culture filtrate of P. florida while, the activity was minimum in 8 days old culture filtrate. Cellulase production was maximum in acidic medium (pH 4.0) as compared to neutral (7.0 pH) and alkaline (9.2 pH) medium.
