Several bacterial strains isolated from the rhizosphere of different plants including Artemisia fragrans, A. caucasica, Kallidium capsicum and Bassia hyssopsifolia growing on oil-contaminated soils of Absheron peninsula (Azerbaijan) were found to be capable to produce indole-3-acetic acid (IAA). Among the rhizosphere bacteria Pseudomonas putida 21 had the potential of producing IAA in reasonable amounts. The strain was remarkable for its ability to grow in the presence of high oil concentrations. We found that lower concentrations (5 - 10 g/l) of oil led to greater production of IAA. When the bacteria were incubated with 10 g/l oil for 3 days 39,3 mg of IAA was formed. When 50 g/l oil was added the culture medium of P. putida 21 contained 37,1 mg/l of IAA.
