Optimization Of Coffee Wastes For The Cultivation Of Pleurotus Ostreatus

Solid state cultivation (SSC) was carried out to evaluate the feasibility of using coffee wasternas substrates for the production of the edible mushroom, Pluerotus ostreatus. Coffee huskrnand coffee pulp powder media were used as a good culture media for Pleurotus ostreatus.rnAddition of supplementary substrate such as, Wheat bran (WB), Chicken manure (ChM),rnCow dung (CD), Noug meal (NM) and Ash improved yield (production) of the mushroom.rnComposted coffee waste gave better yield than fresh coffee waste. Highest yield (1361.74 andrn1232.18g) was obtained from aerobic composted (for eight (8) days) coffee parchment andrnhusk when it was supplemented with 18% cow dung and 8% chicken manure, respectively.rnWith aerobic composted coffee parchment as a substrate the biological efficiency reachedrn90.74% with four flushes after 90 days. With coffee husk as a substrate the biologicalrnefficiency reached 98.57% in 90 days. In the case of fresh substrate the highest biologicalrnefficiency 61.48% and 74.73% was obtained from coffee parchment and coffee husk,rnrespectively. In all cases low biological efficiency was recorded from the substraternsupplemented with 18% nug meal and 2% ash. There was significant difference (at P
