Kahramanmaraş Biber Alanlarından İzole Edilen Toprak Bakterilerinin Phytophthora capsici’ye Karşı Etkisinin Belirlenmesi

Abstract

For the study, 36 soil samples with roots parts were taken from root zone of better grown healthy pepper plants from the pepper fields of Kahramanmaras province. Bacterial isolations were made from collected soil samples. Overall, 713 isolates were obtained from the bacteria colonies based on the morphological characteristics differences. By measuring the radius of inhibition zone, ZHA17 was determined to be most effective isolate. Fifteen isolates were selected from these bacteria in such a way to establish a zone to inhibit the growth of Phytophthora capsici and used in pot experiments under controlled conditions. The isolates were identified as Bacillus pumilus, B. subtilis ss subtilis, Mycobacterium confluentis, M. immunogenum, Paenibacillus castaneae, Pseudomonas fluorescens, P. viridilivida and Tsukamurella paurometabola bacteria species according to Biolog GEN III identification system.
