Pseudoalteromonas epidermidis sp. nov. isolated from skin of bandtail puffer fish (Sphoeroides spengleri)

Abstract

AbstractThis manuscript provides the description of the bacterial strain designated A520T(A520T= CBAS 737T= CAIM 1944T) characterized by Gram-negative, flagellated, aerobic bacteria. It was obtained from the skin of the bandtail pufferfishSphoeroides spengleri(Tetraodontidae Family), collected in Arraial do Cabo, located in the Rio de Janeiro region, Brazil. Optimum growth occurs at 25 - 30 °C in the presence of 3% NaCl. The genome sequence of the novel isolate consisted of 4.502 Mb (4,082 coding genes and G+C content of 41.1%). The closest phylogenetic neighbor wasPseudoalteromonas shioyasakiensisJCM 18891T (94.8% Average Amino Acid Identity and 51.8% Genome-to-Genome-Distance) and several in silico phenotypic features are useful to differentiate the proposed new species,Pseudoalteromonas epidermidissp. nov., from its closest phylogenetic neighbors, including Acetate utilization, Sucrose, L-Arabinose, L-Rhamnose and Gas from glucose. The genome of the novel species also contains 3 gene clusters (~66.81 Kbp in total) coding for different types of bioactive compounds that may account to several possible ecological roles in the bandtail pufferfish host.
