A novel bacterial strain, designated EC29 T , was isolated from the brown alga Ecklonia cava collected on Jeju Island, Republic of Korea. Cells of strain EC29 T were Gram-stain-negative, aerobic, rod-shaped and motile by gliding. Growth was observed at 10-30 8C (optimum, 20-25 8C), at pH 6.0-9.5 (optimum, pH 7.5) and in the presence of 1-5 % (w/v) NaCl. Phylogenetic analyses based on the 16S rRNA gene sequence revealed that the strain belonged to the genus Winogradskyella. Strain EC29 T exhibited the highest 16S rRNA gene sequence similarities, of 96.5-97.8 %, to the type strains of Winogradskyella pulchriflava EM106 T , Winogradskyella echinorum KMM 6211 T and Winogradskyella ulvae KMM 6390 T . Strain EC29 T exhibited ,27 % DNA-DNA relatedness with Winogradskyella pulchriflava EM106 T and Winogradskyella echinorum KMM 6211 T . The predominant fatty acids of strain EC29 T were iso-C 15 : 0 , iso-C 15 : 1 G, C 15 : 0 , iso-C 17 : 0 3-OH, iso-C 15 : 0 3-OH and anteiso-C 15 : 0 .The DNA G+C content was 31.1 mol% and the major respiratory quinone was menaquinone-6 (MK-6). Based on a polyphasic study, strain EC29 T is considered to represent a novel species of the genus Winogradskyella, for which the name Winogradskyella eckloniae sp. nov. is proposed. The type strain is EC29 T (5KCTC 32172 T 5JCM 18703 T ).

A Gram-stain-negative, non-flagellated, non-gliding, aerobic and rod-shaped bacterium, designated TYO-19 T , was isolated from an oyster collected from the South Sea in South Korea, and was subjected to a taxonomic study using a polyphasic approach. Strain TYO-19 T grew optimally at 30 8C, at pH 7.0-8.0 and in the presence of 1.0-2.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences showed that strain TYO-19 T belonged to the genus Winogradskyella, clustering coherently with the type strain of Winogradskyella epiphytica. Strain TYO-19 T exhibited a 16S rRNA gene sequence similarity value of 99.7 % to W. epiphytica KMM 3906 T and 94.2-96.9 % to the type strains of other species of the genus Winogradskyella. Strain TYO-19 T contained MK-6 as the predominant menaquinone and iso-C 15 : 1 G, iso-C 17 : 0 3-OH, iso-C 15 : 0 and anteiso-C 15 : 0 as the major fatty acids. The major polar lipids detected in strain TYO-19 T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content was 39.0 mol% and the mean DNA-DNA relatedness value with the type strain of W. epiphytica was 59¡4.3 %. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain TYO-19 T is separated from recognized species of the genus Winogradskyella. On the basis of the data presented, strain TYO-19 T is considered to represent a novel species of the genus Winogradskyella, for which the name Winogradskyella crassostreae sp. nov. is proposed. The type strain is TYO-19 T (5KCTC 42462 T 5NBRC 110924 T ).

“…Persicirhabdus, known for particle adherence in sediments (Freitas, et al 2012) or on plastic debris (Oberbeckmann, et al 2016), was abundant in particle-attached total communities in foam but not very active ( Figure 6). Both Persicirhabdus and Winogradskyella are well-known for their polysaccharide-degrading capacities (Cardman, et al 2014;Yoon and Lee 2012) and, hence, might prefer to stick to organic materials feeding or sheltering them. Microbes with a free-living lifestyle, such as Planktomarina, for example, represent a very prominent and active group of the Rhodobacteraceae in marine temperate and (sub-)polar areas of the oceans and coastal waters (Giebel, et al 2009;Giebel, et al 2011;Selje, et al 2004;Voget, et al 2015).…”

The occurrence of foams at oceans’ surfaces is patchy and generally short-lived. However, a detailed understanding of bacterial communities inhabiting foams is lacking. In this study, we investigate if marine foams differ from the sea-surface microlayer (SML), a <1 mm thick layer at the air-sea interface. The comparison of marine foams, SML and underlying water collected from the North Sea and Timor Sea showed that foams were often characterized by highest abundance of small phototrophic and prokaryotic cells as well as highest concentrations of surface-active substances (SAS). Amplicon sequencing based on 16S rRNA revealed a comparable bacterial community in SML and foam. DNA and rRNA based sequence data suggest that Pseudoalteromonas, a typical member of the SML, was highly active and thus might enhance foam formation and stability by producing SAS. Although foams contained some specific taxa, our study supports the hypothesis that foam represents a compressed version of the SML. Foam is characterized by increased cell numbers, high SAS concentration, and a significant fraction of overlapping bacteria with SML. Due to the compressed nature of foam and SML compared to the underlying water, bacteria thriving in both surface phenomena have likely implications for biogeochemical cycling and air-sea exchange processes.One-sentence summaryWhile foams at the oceans’ surface have a unique bacterial community signature, they represent a compressed version of the sea-surface microlayer with typical bacterial inhabitants.
