Cultivation of oyster mushrooms on wheat straw and bagasse substrate amended with distillery effluent

Abstract

Molasses-based distilleries produce large quantities of dark coloured effluent, which is a major cause of environmental pollution. An experiment was conducted to investigate the efficacy of distillery effluent amendment for edible mushroom production. Three species of oyster mushroom, namely Pleurotus florida Eger (EM 1303), Pleurotus pulmonarius (Fries) Quelet (EM 1302) and Pleurotus sajor-caju (Fries) Singer (EM 1304) were grown on wheat straw (variety UP 2338) and bagasse amended with post-anaerobic distillery effluent, a high organic load wastewater with high biochemical oxygen demand and chemical oxygen demand. Three different levels of effluent treatment were applied to bagasse and wheat straw. Wheat straw was found to be the preferred substrate and showed better results than bagasse in all treatments with respect to yield, biological efficiency (BE) and dry matter loss. P. florida (EM 1303) and P. pulmonarius (EM 1302) gave significantly enhanced yield with increasing levels of effluent, with BE reaching highest at 238.6% for P. florida (EM 1303). Using bagasse as a substrate, P. sajor-caju (EM 1304) and P. pulmonarius (EM 1302) exhibited a decreasing trend as compared to control. However, the effect of effluent concentrations did not influence yield and BE significantly in case of bagasse. The dry matter loss of the substrate varied from 9.4% to 53.4% in wheat straw and 17.5% to 45.2% in bagasse respectively.

Enhanced production of ligninolytic enzymes and decolorization of molasses distillery wastewater by fungi under solid state fermentation

“…Agriculture residues such as wheat straw and corncob powder as a support provides the fungus a similar environment to its natural habitat and offers the possibility of reusing an agricultural waste. Recently, enhanced production of P. ostreatus (Florida) EM 1303 on wheat straw amended with distillery effluent was reported by Pant et al (2006). Among the five selected fungi, only two, A. flavus TERI DB9 and P. ostreatus (Florida) EM 1303 were found as laccase producers (Table 3).…”

“…In order to check the decolorization due to substrates alone, non-sterile blank controls were taken to mimic the actual effluent from the industries where effluent was inoculated with wheat straw and corncob without any fungal growth on them. Pant et al (2006) Statistical analysis In all the experiments described in this study triplicates were set up for each parameter tested. Completely randomized design was used and sampling was random.…”

Optimization of oyster (Pleurotus ostreatus) mushroom cultivation using locally available substrates and materials in Debre Berhan, Ethiopia

“…Addition of supplements (rice husk) to waste paper significantly increase spawn running, pin head formation, fruit body formation and mushroom yield [17]. Similarly, cultivation of oyster mushroom on wheat straw and bagasse amended with distillery effluent yield better result than substrates without distillery [18] effluent. The effects of wheat bran, oil seed cake (fig 2) and cow dung on growth were evaluated and it was found that oil seed cake gave maximum yield (table 1 and fig 2).…”

Wood production, wood technology, and biotechnological impacts

“…wheat, rice, maize, banana leaves, pumpkin, etc.) as wastes from local agricultural practices are used for cultivation of the fungus in Europe, Asia, Latin America or Africa (Zadrazil 1997, Obodai et al 2003, Bonatti et al 2004, Mendez et al 2005, Salmones et al 2005, Pant et al 2006, Tisdale et al 2006. Possibilities of investment play another major role in how to cultivate mushrooms.…”
