Oyster Mushroom Cultivation on Different Cellulose Substrates

Abstract

Abstract Four lignocellulosic substrates (sawdust, peat of coconut husk, narrow leaf cattails and bagasse) were used for Pleurotus ostreatus cultivation, and 3-6 flushes were obtained from these substrates. A bagasse substrate accelerated the mushroom growing processes. The mycelial completed colonization, primordium initiation and fruiting body formation were found within 28, 40 and 44 days, respectively. The sawdust gave the maximum mushroom yield (536.85 g per 1 kg substrate) and this yield was significantly different to those found from bagasse (360.84 g), peat of coconut husk (278.78 g) and narrow leaf cattails (112.10 g) at a confidence level of 95%. However, the highest percentages of biological efficiency was obtained in bagasse substrate even it showed lower mushroom yield than sawdust. Low percentages of biological efficiency were found in peat of coconut husk (56.76%) and narrow leaf cattails (44.67%). Even the highest percentage of biological efficiency was obtained from bagasse (103.56%) but this percentage was insignificant differences at a confidence level of 95% to those found in control (95.02%; sawdust). When the percentage of biological efficiency was taking into account the lignocellulosic substrate likes bagasse has shown great potential for use as a raw material instead of sawdust since this substrate provides an economically acceptable production alternative for P. ostreatus cultivation
