Bu çalışmada, Çorum (Kargı ve Osmancık) çevresindeki yaylalardan izole edilen aktinomiset izolatlarının poliketit sentaz ve ribozomal olmayan peptit sentetaz biyosentetik sistemlerinin varlığı moleküler tekniklerle araştırılmıştır. Toplamda 15 tane Actinobacteria üyesinin sekonder metabolit biyosentetik genlerinin (PKS I-II/NRPS) varlığı PCR temelli incelenmiştir. Yapılan çalışmanın sonuçlarına göre, 15 tane aktinomiset izolatının 7 tanesi PKS-I, 11 tanesi PKS-II ve 14 tanesinin NRPS gen bölgesine sahip olduğu bulunmuştur. Sonuçlar değerlendirildiğinde izolatların nonribozomal peptid sentetaz (NRPS) gen kümelerini tip I-II poliketit sentazlar (PKS-I-II) gen kümelerinden daha fazla içerdiği görülmüştür. Ayrıca 5 izolatın üç gen kümesini bir arada bulundurduğu tespit edilmiştir. Sonuç olarak yaylalardan izole edilen aktinomisetlerin yüksek sekonder metabolit üretme kapasitesine sahip olduğu görülmüştür.
