Abstract
The utilization of bean curd refuse as a nutrient for the cultivation of Pleurotus ostreatus was investigated by using sawdust substrates with bean curd refuse and rice bran mixed at different ratios. The cultivation on the sawdust substrates containing bean curd refuse at 40-80 % in nutrients were shortened the period by about 2 weeks and increased the yield of fruit bodies by 1.5-1.8 times compared with the substrate in which the rice bran as supplemented as a sole nutrient additive. The mixture of bean curd refuse and rice bran as nutrient additives into the sawdust substrate produced low C/N ratio. Bean curd refuse is, therefore, useful nutrient additive for the cultivation of P. ostreatus in combination with rice bran for preparing the substrate.
