“…Individual polar lipids were identified by spraying reagents as described Park et al [11]. The predominant ubiquinone detected in strain JBTF-M23 T was Q-8, at a peak area ratio of approximately 91 %, which is consistent with that shown in some species of the genus Pseudoalteromonas [4, 10, 11]. The major fatty acids (>10 % of the total fatty acids in all growth phases) found in strain JBTF-M23 T were summed feature 3 (C 16 : 1 ω 7 c and/or C 16 : 1 ω 6 c ), C 16 : 0 and C 18 : 1 ω 7 c ().…”

“…One complete 16S rRNA gene sequence (1545 bp) from the genome of strain JBTF-M23 T extracted using ContEst16S [18] was compared with the partial 16S rRNA gene sequence obtained from Sanger sequencing, and the two sequences were found to be 100 % similar. The DNA G+C content of strain JBTF-M23 T from genomic sequence data was 41.98 %, a value in the range reported for Pseudoalteromonas species ( [4, 10, 11]). The genomic sequence data of strain JBTF-M23 T had ANI values of 71.3, 76.6 and 76.5 % to those of P.…”

“…At the time of writing, the genus Pseudoalteromonas comprises more than 47 species with validly published names (https://lpsn.dsmz.de/genus/pseudoalteromonas [2];). Members of the genus Pseudoalteromonas are characterized to be Gram-stain-negative, aerobic or facultatively anaerobic, oxidase-positive rods and by having ubiquinone-8 as predominant isoprenoid [3, 4]. Members assigned into the genus Pseudoalteromonas have been isolated from marine organims and marine environments including seawater and marine sediments [1–3, 5–13] with one exception [4].…”

A Gram-stain-negative, aerobic, non-spore-forming, motile by single polar flagellum and ovoid or rod-shaped bacterial strain, designated JBTF-M23T, was isolated from tidal flat sediment collected from the Yellow Sea, Republic of Korea. Neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strain JBTF-M23T fell within the clade comprising the type strains of Pseudoalteromonas species, clustering with the type strains of P. byunsanensis and P. amylolytica . Strain JBTF-M23T exhibited the highest 16S rRNA gene sequence similarity value (98.6 %) to the type strain of P. rubra and sequence similarities of 98.3 and 97.7 % to the type strains of P. byunsanensis and P. amylolytica, respectively. The DNA G+C content of strain JBTF-M23T from genomic sequence data was 41.98 %. The ANI and dDDH values between strain JBTF-M23T and the type strains of P. rubra , P. byunsanensis and P. amylolytica were 71.3–76.6 and 19.4–19.9 %, respectively. Strain JBTF-M23T contained Q-8 as the predominant ubiquinone and C16 : 1 ω7c and/or C16 : 1 ω6c, C16 : 0 and C18 : 1 ω7c as the major fatty acids. The major polar lipids of strain JBTF-M23T were phosphatidylethanolamine and one unidentified aminolipid. Distinguished phenotypic properties, along with the phylogenetic and genetic distinctiveness, revealed that strain JBTF-M23T is separated from recognized Pseudoalteromonas species. On the basis of the data presented, strain JBTF-M23Tis considered to represent a novel species of the genus Pseudoalteromonas , for which the name Pseudoalteromonas caenipelagi sp. nov. is proposed. The type strain is JBTF-M23T(=KACC 19900T=NBRC 113647T).

Bacterial strains of the genus Pseudoalteromonas, which includes 48 species, are widely distributed in various ocean environments. Many strains are often abundant and the highest protease producer among marine culturable protease-secreting bacteria, suggesting their important role in marine organic nitrogen degradation and cycling. The extracellular proteases of Pseudoalteromonas are diverse, including serine proteases, metalloproteases, and cystine proteases. Pseudoalteromonas proteases have unique properties, such as cold adaptation, salt tolerance, distinct substrate specificity, and catalytic mechanism. They play important ecological roles in marine organic nitrogen degradation and in the interactions of Pseudoalteromonas with other organisms. Some Pseudoalteromonas proteases have shown promising application potentials in bioactive peptide preparation and meat processing. In this review, advances in our knowledge of Pseudoalteromonas proteases are introduced, with a focus on diversity, characters, ecological significance, and application potentials.
