A microorganism (Azotobacter sp.) was isolated from soil samples from the Agronomy Faculty campus and its ability to accumulate poly-beta-hydroxyalkanoate (PHAs) polymers was analyzed. The isolated strain (named No 8) accumulated 8 micrograms PHA/m of culture media as intracytoplasmic granules. The following properties of the strain were analyzed: utilization of different carbon sources, antibiotic resistance, optimal pH and temperature, pigment production, nitrogen fixation, proteolytic activity, acid and hydrogen sulphide production, optimal growth temperature, cyst formation, growth on phenol and sodium fluoride, catalase, pleomorfism and mobility. The synthesized polymer showed valuable properties respect to organic solvents resistance.
