Characterization of alginate-degrading bacteria isolated from seaweed-producing areas of South Korean territory and verification of the bacteria as plant growth-promoting biofertilizer.

ABSTRACT: Alginate, a carbohydrate polymer produced by seaweed and some bacteria, is widely used in the food and medicine industries. Alginate oligosaccharides, produced by depolymerizing alginate, exhibit diverse biological functions, such as plant protection and growth promotion, enhancement of microbial metabolic activity, and potential applications in biofuel production. This study isolated 13 alginate-degrading bacterial strains from over a thousand seaside soil bacteria in South Korea and investigated their alginate-degrading characteristics. Through 16S rDNA sequencing, Marinomonas sp., Zobellella sp., and Pseudomonas sp. were newly identified at the subspecies level. Notably, this study is the first to report the alginate-degrading capability of Zobellella sp. The
