Original Abstract

Azotobacter vinelandii is a plant growth-promoting bacterium (PGPR), capable of synthesizing two completely different biopolymers with great application potential. Polyhydroxyalkanoates (PHAs) are produced and stored in the form of intracellular granules, while alginate is produced extracellularly and used for bacterial protection. Besides the biopolymer production, A. vinelandii shows biological activities for the stimulation of plant growth, thus it can be used as a bioinoculant. Bioinoculants enrich soil in nitrogen and phosphorus levels, decrease pathogens, produce phytohormones, help with phytoremediation by chelating heavy metals from the soul, retain moisture etc. These bioinoculant properties lead to a better quality of soil, and the improvement of crop growth and yield. Furthemore, bioinoculants can be used as a biological alternative to chemical fertilizers. In this work, we screened various effects of plant growth stimulations by the bacterium A. vinelandii. The test for the prodduction of phytohormone auxin (indole acetic acid), iron- chelating siderophores and phosphate solubilization showed possitive results, resulting in a new generation of bacterial inoculants encapsulated in hydrogel- based carriers.
