Abstract
Solid state cultivation (SSC) was carried out to evaluate the feasibility of using coffee waste as substrates for the production of the edible mushroom, Pluerotus ostreatus. Coffee husk and coffee pulp powder media were used as a good culture media for Pleurotus ostreatus. Addition of supplementary substrate such as, Wheat bran (WB), Chicken manure (ChM), Cow dung (CD), Noug meal (NM) and Ash improved yield (production) of the mushroom. Composted coffee waste gave better yield than fresh coffee waste. Highest yield (1361.74 and 1232.18g) was obtained from aerobic composted (for eight (8) days) coffee parchment and husk when it was supplemented with 18% cow dung and 8% chicken manure, respectively. With aerobic composted coffee parchment as a substrate the biological efficiency reached 90.74% with four flushes after 90 days. With coffee husk as a substrate the biological efficiency reached 98.57% in 90 days. In the case of fresh substrate the highest biological efficiency 61.48% and 74.73% was obtained from coffee parchment and coffee husk, respectively. In all cases low biological efficiency was recorded from the substrate supplemented with 18% nug meal and 2% ash. There was significant difference (at P<0.05) observed between fresh and aerobic composted coffee parchment and coffee husk as well as different supplementary substrates on yield and the biological efficiency. In both cases with different supplementary substrate first flash gave high yield. The result of these experiments has showed that the feasibility of using composted coffee husk and coffee parchment as substrates with different supplementary substrate for cultivation of edible mushroom in SSC.
