The Potency Of Oil Palm Plantation Wastes For Mushroom Production

Abstract

Indonesia has become the world's largest palm oil producer with total area of oil palm plantation being 7.3 million ha in 2009 wich produced a huge quantity of biomass by-product such as empty fruit bunches (EFB) estimated at 43 million tons, as well as produced liquid and solid wastes from palm oil mill effluent (POME). lbis research was aimed to study the potency of EFB and POME on growth of white oyster mushroom (F isolate of Pleura/us sp.) and GKSA isolate of Ganoderma boninense. F isolate was grown on EFB, Paraserian/hes falca/aria sawdust and mixture ofbotb substrates with proportion I: I respectively. The results showed that EFB could be used as a substrate of Pleuro/us fruit body production with biological efficiency that reached 152%, and even the growth went faster than the other substrates. As well as GKSA isolate could used the EFB as a substrate of fruit body production and it could decrease C/N ratio up to 84% at vegetative phase and lignin concentration up to 66% at reproductive phase. In addition the POME have induced significant increasing of the GKSA isolate growth up to 62% at 20% of liquid POME concentration in malt media and reached 64% of growth at 10% of solid POME in the same media. Based on these results the abundant wastes from the oil palm plantation were considered suitable for mushroom production and spent mushroom substrates can be used as soil fertilizers at oil palm plantation as well as for animal feed.
