Self encapsulation of plant growth-promoting bacteria Azotobacter vinelandii for their use as next-generation bioinoculants

Popis výsledku v původním jazyce

Azotobacter vinelandii is a plant-growth-promoting bacterium (PGPB), capable of synthesizing two different biopolymers with great application potential. Polyhydroxyalkanoates (PHA) are produced and stored in a form of intracellular granules, whereas alginate is produced extracellularly. Plant growth-promoting bacteria can be used as bio-inoculants to increase yields in agriculture. Encapsulation of bacteria into hydrogel-based carriers substantially improves the application potential of the bioinoculant as well as the viability and robustness of the bacterial culture. In this work, the alginate produced by the bacteria themselves was crosslinked with a calcium chloride solution to form a hydrogel carrier with encapsulated bacteria. This unconventional concept that we ter- med „self encapsulation“ simplifies bacterial encapsulation and production of hydrogel carriers, reduces the cost, and expands its usability in numerous applications. Firstly, we screened five strains of Azotobacter vinelandii to
