Chitinolytic and Fungicidal Potential of the Marine Bacterial Strains Habituating Pacific Ocean Regions.

Screening for chitinolytic activity in the bacterial strains from different Pacific Ocean regions revealed that the highly active representatives belong to the genera , , , and . The widely distributed chitinolytic species was isolated from the sea urchin . Among seventeen isolates with confirmed chitinolytic activity, only the type strain KMM 3630 and the strains of putatively new species sp. B530 and sp. Sgm 5, isolated from sea water (Vietnam mollusc farm) and the sea urchin (Peter the Great Gulf, the Sea of Japan), significantly suppressed the hyphal growth of that is perspective for the biocontrol agents' development. The results on chitinolytic activities and whole-genome sequencing of the strains under study, including agarolytic type strain Dji, found the new functionally active chitinase structures and biotechnological potential.
