Abstract

In this study, fatty acid compositions of Pleurotus ostreatus (Jacq. ex. Fr) Kum.var. salignus, Pleurotus sajorcaju (FR). Singer, Pleurotus florida Fovose grown on different compost mediums such as clover stalk (CS), walnut husk waste (WH), sugar beet pulp (SP) were determined. Analysis was performed by high performance gas chromatography. According to the fatty acid analysis results, linoleic acid, palmitic acid, pentadeconoic acid, stearic acid was found predominantly. Present results showed that the studied three species have high palmitic acid (19.7-33.06%), linoleic acid (36.69-78.89%) and docosadyenoic acid (9.78-28.80%). On the other hand the presence of lauric acid, linolenic acid, eicosadienoic acid, eicosatrieonic acid, docosatetraenoic acid were determined.As a result; it was found that Pleurotus florida Fovose has rich fatty acid content among the studied taxa

Abstract

Bu çalışmada, yonca sapı (YS), ceviz kabuğu atıkları (CK), şeker pancarı posası (ŞP) gibi farklı kompost ortamlarında yetiştirilen Pleurotus ostreatus (Jacq. ex. Fr) Kum. var. salignus, Pleurotus sajor-caju (FR). Singer, Pleurotus florida Fovose’nin yağ asidi kompozisyonları belirlenmiştir. Analizler gaz kromatografi cihazı ile yapılmıştır. Yağ asidi analizlerinde; linoleik asit, palmitik asit, pentadekonoik asit, stearik asit ağırlıklı olarak bulunmuştur. Türlerin en fazla palmitik asit (%19.7-33.06), linoleik asit (%36.69-78.89), dokosadienoik asit (%9.78-28.80) içerdiği tespit edilmiştir. Diğer yandan laurik asit, linolenik asit, eikosadienoik asit, eikosatrieonik asit, dokosatetraenoik asit gibi yağ asitlerinin de varlığı tespit edilmiştir. Sonuç olarak; çalışılan üç takson arasında Pleurotus florida Fovose’nin daha zengin yağ asidi içeriğine sahip olduğu bulunmuştur.
