Complete genome sequence of Psychrobacter cibarius AOSW16051, a trimeric autotransporter adhesin synthesizing bacterium isolated from the Baltic Sea

Bacteria of the genus Psychrobacter are widely distributed in the global low-temperature marine environment and have been studied for their effects on the settlement and metamorphosis of marine invertebrates. Psychrobacter cibarius AOSW16051 was isolated from the surface water samples of the Baltic Sea on the edge of the Arctic Ocean. Here, we present the complete genome of strain AOSW16051, which consists of a circular chromosome composed of 3,425,040 nucleotides with 42.98% G + C content and a circular plasmid composed of 5846 nucleotides with 38.66% G + C content. The genes predicted in this strain showed its strong outer membrane system, type VI secretion system and adhesion system. Trimeric autotransporter adhesins (TAAs) has been identified in the genome of P. cibarius AOSW16051, which has a variety of biological functions in interacting with host cells. However, there are no reports on TAAs in marine bacteria and aquatic pathogenic bacteria. By analyzing the genomic data, we can gain valuable insights to enhance our understanding of the physiological characteristics of P. cibarius, as well as the biological functions of TAAs and their role in triggering metamorphosis of invertebrate larvae.
