Bag opening technique for bag spawn culture of spit gill mushroom (Schizophyllum commune)
Main Article Content
Abstract
Schizophyllum commune (spit gill mushroom), the wood decay is the most beneficial mushroom. It has been known as the medicinal mushroom. It contains high essential medicinal compound, anti-oxidant, anti-cancer polysaccharide and producing anti-bacterial secondary metabolites. Bag opening technique was conducing to enhance produce of bag spawn mushroom culture by using sawdust as culture medium. Vertical cutting, 45 degree skew cutting and cutting stripe number were compared for fruiting body productivity. The result reveals that 5 stripe 45 degree skew cutting per bag enhanced the highest produce (fresh weigh) of 187.76 g/ bag. However, it was not significantly different from 4, 5 and 6 stripe vertical cutting of 180.39, 179.39, and 176.67 g/bag respectively but, it was significantly higher than 5 stripe 45 degree skew and 6 stripe vertical cutting of 157.20 and 54.11 g/bag respectively. This technique enhanced mushroom productivity per dry weigh of spawn was 31.29 %. The cost and return per bag were 11.26 and 16.90 baht; and benefit was 8.45 baht/bag with the return on investment 75.09 %.
