Abstract

This study was carried out to investigated the avaiability of dried Koojongsi persimmon peels (KPP) as a useful mushroom medium using Pleurotus eryngii ASI 2312. Mushroom cultivation medium used in this study was mixed with medium mixture, corn cob and sawdust (220:65:15, v/v). Dried KPP was replaced mushroom cultivation medium (control) with 5, 10, 15, 20, 30, 40, 50% dried KPP. The T-N content of dried KPP treatments decreased to increase replaced ratio of the dried KPP and C/N ratio was increased to increase replaced ratio of the dried KPP. But T-C content of dried KPP treatments was similar to untreated control. The average cultivating periods of mycelium on dried KPP treatments was delayed to increase replaced ratio of the dried KPP and cultivating periods was delayed over 30% dried KPP treatments. The length of stipe of dried KPP treatments was longer than that of the untreated control to increase replaced ratio of the dried KPP and thickness of stipes was tend to be thinner than that of the untreated control to increase replaced ratio of the dried KPP. The moisture, carbohydrate, crude protein and crude ash content of mycelial were similar to untreated control, but crude fatty acid was increased to increase replaced ratio of the dried KPP. The ${\beta}-glucan$ content of 10% and 15% treatments were higher than untreatment control. The results based on cultivation yield and ${\beta}-glucan$ content indicated that optimal mixture ratio dried KPP was 15%.
