“…Some culturable OTUs had a restricted distribution, appearing only in very low numbers or in only one of the samples. However, some of these, such as the genera Roseivirga or Winogradskyella, found only in surface waters of the Atlantic Ocean, Polaribacter, only retrieved from surface NW Mediterranean waters or Novosphingobium, isolated from deep waters of the South Atlantic, had previously been described in other culturedependent studies from other oceanographic locations [81][82][83][84][85]. Additionally, metadata information retrieved from the Closest Cultured Match and Closest Environmental Match of each one of the strains (Table S3 and S4) also indicated the presence of such restricted genera in other depths and oceanographic regions.…”

Nowadays, there is a significant gap in the knowledge of the diversity and patterns for marine heterotrophic culturable microorganisms. In addition, most of the bacterial isolation efforts have focused on the photic ocean leaving the deep ocean less explored.We have isolated 1561 bacterial strains covering both photic (817) and aphotic layers (744) including isolates from the oxygen minimum zone (362) and the bathypelagic (382) from a variety of oceanographic regions including the North Western Mediterranean Sea, the North and South Atlantic Oceans, the Indian, the Pacific, and the Arctic Oceans. The partial sequencing of the 16S rRNA gene of all isolates revealed that they mainly affiliate with the classes Alphaproteobacteria (35.9%) and Gammaproteobacteria (38.6%), as well as, phylum Bacteroidetes (16.5%). The genera Alteromonas and Erythrobacter were the most widespread heterotrophic bacteria in the ocean able to grow on solid agar media. When comparing the sequences of all isolates, 37% of them were 100% identical.In fact, we found that 59% of the total aphotic isolates were 100% identical to photic isolates, indicating the ubiquity of some bacterial isolates along the water column.Unweighted UniFrac distances did not show significant differences among stations regardless of their geographic distance or depth, reflecting the wide dispersion of the culturable bacterial assemblage. This isolates collection provides an overview of the distribution patterns of cosmopolitan marine culturable heterotrophic bacteria.

Wi.no.grads.ky.el'la. N.L. fem. n. Winogradskyella named after Sergey Winogradskyi, Russian soil microbiologist who made great contributions to the taxonomy of bacteria of the Cytophaga‐Flavobacterium‐Bacteroides phylum. Bacteroidetes / Flavobacteriia / Flavobacteriales / Flavobacteriaceae / Winogradskyella Rod shaped with rounded ends or rod‐coccoid‐shaped cells 0.2–1.0 × 0.4–10.0 µm. Spores are not formed. Cells are not flagellated. The majority of the strains are motile by gliding. Produce nondiffusible yellow, orange, or orange‐yellow carotenoid pigments. No flexirubin type of pigments are produced. The cells can form net‐work‐like structures. Chemoorganotrophs. Aerobic or facultatively anaerobic. Mesophilic . Catalase‐, oxidase‐, and alkaline phosphatase positive. Arginine dihydrolase, lysine decarboxylase, ornithine decarboxylase, and tryptophan deaminase are not produced. Gelatin is hydrolyzed , but chitin is not attacked. Indole is not produced. Marine , from coastal habitats. Require seawater or Na + for growth. The predominant cellular fatty acids are iso‐C 15:1 G, iso‐C 15:0 , iso‐C 15:0 3‐OH, iso‐C 16:0 3‐OH, and iso‐C 17:0 3‐OH . The major respiratory quinone is MK‐6. The main polar lipid is phosphatidylethanolamine. Isolated from marine environments, including seawater, sediments, seaweeds, sea urchins, starfishes, molluscs, and sponges. DNA G + C content (mol%) : 30–39 ( T m and HPLC). Type species : Winogradskyella thalassocola Nedashkovskaya, Kim, Han, Snauwaert, Vancanneyt, Swings, Kim, Lysenko, Rohde, Frolova, Mikhailov, and Bae 2005, 52 VP emend.
