The tannin obtained from Valonia oak mostly utilized in leather industry. After having been extracted for tannin, the waste has no industrial utilization yet in Turkey. Milled valonia oak wastes composed of acorn cup held high humidity; therefore, has high drying cost for transporting as well as storage problems of the mills. Valonia oak wastes were used as compost to cultivate P streams. Results indicated that the mycelia development on oak wastes were realized 45 days yield of 24.5% (weight/weight) which is to be considered as potential substrate for P ostreatus cultivation.tr10.5053/ekoloji.2011.7810info:eu-repo/semantics/closedAccessPleurotus ostreatussubstrateacorn wastesArticle20786065WOS:000291232900010Q4
