Pineapple rind is a by- product of the pineapple processing industry and contains nutri-
ents and other compounds which must be utilized as a bioresource for socio- economic
benefits while preventing the potential problems of improper agroindustrial biomass
disposal methods. Pleurotus ostreatus is an edible oyster mushroom with medicinal
properties and can be cultivated on various agroindustrial biomass, including sawdust
containing supplements. Pineapple rind was powdered and used as a supplement of
composted sawdust at 2%, 5%, 10%, 12%, 15%, and 20% (w/w) on dry weight basis. A
control treatment consisted of composted sawdust supplemented with rice bran at
12% (the most utilized composition in Ghana). P. ostreatus strain EM- 1 was cultivated
on these treatments. Factors investigated included the spawn run period, yield, fruit-
ing body weight and size, biological efficiency, and nutritional composition (proximate
composition and Copper, Zinc and Lead content) of fruiting bodies harvested from
selected high- yielding treatments and the control treatment. Full colonization of all
treatments occurred by the 34th day of incubation. Enhanced yield, fruiting body
weight and size, and biological efficiency were generally recorded with supplementa-
tion at lower concentrations (2% and 5%) compared to treatments supplemented at
higher concentrations. There was also a supplement concentration- dependent altera-
tion of the nutritional composition of the mushroom. Powdered pineapple rind can be
utilized as an organic supplement at relatively low concentrations in composted saw-
dust for P. ostreatus strain EM- 1 cultivation. The use of lower concentrations of pow-
dered pineapple rind in composted sawdust is advantageous as relatively less input
will be required to produce higher P. ostreatus strain EM- 1 yields. Utilization of pineap-
ple rind for mushroom cultivation will extend the pineapple plant value chain, intensify
mushroom production in a sustainable way, and minimize agricultural losses.
