다국어 초록 (Multilingual Abstract)

In order to use mushroom compost as feedstuffs to exeriments were carried out to determin the variation of general organic composition, degree of htunification, free amino acid and activity of amylase in the compost before cultivation of mushroom and mushroom compost.
The results obtained were summarized as follows;
1. Contents of crude protein and soluble protein of the compost for mushroom cultivation were increased. In the mushroom compost crude protein contents were 10.9% and soluble proteins were 1.95%.
The contents of nitrogen free extract were decrcased in both compost. Crude fiber contents were increased during fermentation but in mushroom compost contents of crude fiber were markedly decreased from 23.7% to 12.4%.
2. Degree of humification during fermentation was increased but in mushroom compost was decreased.
3. The free amino acid which were extrated with alfohol in mushroom compost were identified. that is cysteine, Serine, glycine, threonine. alanine, tynosine, methionine and isoleusine.
4. The value of amylase activity from mushroom compost was about two tims higher than 10 days fermented compost.
