Isolation and Characterization of Pseudomonas Isolates for Antagositic Activities

Abstract

Pseudomonas spp. isolates were isolated from rhizosphere of maize, chickpea and pepper grown in field locations in Şanlıurfa, Turkey. B1, B5, B8, B17, B22, B26, N13, N14, D1, D8, D11, BA2 and BA15 isolates grew in 4% of NaCl. 88.9 % of isolates grew at 41oC. Isolates were resistant chloramphenicol (27.8%), ampicillin (27.8%) and cycloheximide (38.9%). The isolates produced different enzymes and were antagonistics against some plant pathogenic fungi. The highest mean inhibition values, 99.77% RI, were obtained D.sorokiniana with B1, B5, M4 and BA2 isolates
