Sharma, Rishu | Sharma, BM
In the present study, nine species of Pleurotus and their isolates were procured/collected from different sources/locations and cultivated under mushroom house conditions. The crude protein content of various species viz. P.ostreatus, P.sapidus, P.eryngii, P.florida, P.flabellatus, P.florida, P.cystidiosus, P.hypsizygus and P.sajor caju was determined on dry weight basis using micro-kjeldahl method. The protein contents varied from 23.0 per cent to 33.7 per cent in 21 species/isolates of Pleurotus analysed. Five isolates belonged to P.cystidiosus, four to P.ostreatus, three to P.flabellatus, two each to P.eryngii and P.fossulatus and one each to P.sapidus and P.florida. Lowest protein content was found in P.eryngii (23%) and highest in P.ostreatus (33.7%) indicating a high variability among various species/isolates.
