Although bacteriobenthos play a major role in the degradation of particulate organic matter marine sediment, knowledge sediment-adapted lifestyles is still scarce. Here, particle-associated, swimming and swarming benthonic bacterium Pseudoalteromonas sp. SM9913 (SM9913) were illustrated. had clay particle-associated lifestyle, its exopolysaccharide played an important this lifestyle. also motilities, indicating that it may have sediment. The lateral flagella responsible for motility, polar motility. Iron limitation was indispensable inductive signal An analysis motilities mutants demonstrated moved by both motilities. Genomic suggests having two systems most likely common adaptation some to sediment environment. Our results reveal SM9913, providing better understanding environmental bacteria.
