| Title : | ISOLATION AND CHARACTERIZATION OF PLANT GROWTH PROMOTING BACTERIA FOR POTENTIAL BIOREMEDIATION |
| Abstract : | Modern agriculture is based on mineral fertilizers and use of synthetic chemicals in plant protection. Plant growth promoting bacteria (PGPB) represent a promising alternative to chemicals employed in agricultural practice. The aim of this study was to isolate and characterize PGP strains with the ability to promote plant growth from three different locations in the city of Zagreb. Phenotypic characterization of isolates included testing the tolerance to unfavorable soil conditions as well as intrinsic antibiotic resistance, biochemical characterization and screening for plant growth promoting properties. Twenty-four isolates were isolated. 28 % isolates were positive for the phosphate solubilization test, while IAA was produced by all isolates. Half of all isolates had the ability to synthesize lytic enzymes and exopolysaccharides. Some differences were found between isolates regarding their phenotypic characteristic, especially resistance to low pH and high temperatures. |
