“…In fact, the only major characteristics assessed in which the two predatory strains differ from strain CAM03OT is the ability to grow by lysing prey bacteria and a requirement for sea salts. Their next closest cultured relative, L. algicola strain AKS293T, cannot glide, is incapable of growing at 30 C and does not require salt [114]. Strain VCSA14A was found to be very similar to its closest relatives, T discolor strain LLO4 was considerable diversity in prey specificity.…”

Predatory bacteria are ubiquitous in aquatic environments and may be important players in the ecology and biogeochemistry of microbial communities. Three novel strains belonging to two genera of marine flavobacteria, Olleya and Tenacibaculum, were cultured from coastal sediments and found to be predatory on other bacteria on surfaces. Two published species of the genus Tenacibaculum were also observed to grow by lysis of prey bacteria, raising the possibility that predation may be a widespread lifestyle amongst marine flavobacteria, which are diverse and abundant in a variety of marine environments. The marine flavobacterial clade is known to include species capable of photoheterotrophy, scavenging of polymeric organic substances, pathogenesis on animals, the degradation and lysis of phytoplankton blooms and, now, predation on bacterial communities. Strains from the two genera were found to exhibit divergent prey specificities and growth yields when growing predatorily. Olleya sp. predatory cells accumulated to an order of magnitude greater cell densities than Tenacibaculum sp. cells on equivalent prey cell densities. Experiments were conducted to constrain the potential of the novel isolates to affect prey communities under more environmentally relevant conditions. An investigation of the minimum number of predatory cells needed to generate clearings of prey cells found that the inoculation of individual predatory flavobacteria cells can ultimately result in dense lytic swarms. In some cases, the susceptibility of particular prey species to lysis by a flavobacterial predator was found to vary based on the growth state of the prey cells or the presence of their spent growth media. A novel methodology for the experimental study of biofilms was used to assess the impact of exposure to predatory marine flavobacteria on the release of macronutrients from prey biofilms. The Olleya sp. predator had a stimulative effect on macronutrient release while the Tenacibaculum sp. did not, further suggesting the two groups of predators are adapted to different ecological niches.

Begum and S. Shivaji Correspondence S. Shivaji shivas@ccmb.res.inCentre for Cellular and Molecular Biology, Uppal Road, Hyderabad -500 007, India A novel Gram-negative, rod-shaped, non-motile, psychrophilic bacterium, designated strain E4-9a T , was isolated from a marine sediment sample collected at a depth of 276 m from Kongsfjorden, Svalbard, in the Arctic Ocean. The colony colour was golden yellow. Strain E4-9a T was positive for amylase activity at 5 6C. The predominant fatty acids were iso-C 15 : 1 G (21.8 %), anteiso-C 15 : 0 (19.1 %), anteiso-C 15 : 1 A (18.6 %), iso-C 15 : 0 (13.8 %) and iso-C 16 : 1 H (6.4 %). Strain E4-9a T contained MK-6 as the major respiratory quinone. The polar lipids consisted of phosphatidylethanolamine, three unidentified aminolipids (AL1, AL4 and AL5), an unidentified phospholipid and four unidentified lipids (L1, L4 to L6). Based on 16S rRNA gene sequence similarity, it was ascertained that the closest related species to E4-9a T were Lacinutrix copepodicola, L. algicola and L. mariniflava, with sequence similarity to the respective type strains of 98.5, 96.5 and 95.8 %. Phylogenetic analysis showed that strain E4-9a T clustered with the type strain of L. copepodicola and with those of L. algicola and L. mariniflava at distances of 1.5 and 4.8 % (98.5 and 95.2 % similarity), respectively. However, DNA-DNA hybridization with L. copepodicola DJ3 T showed 59 % relatedness with respect to strain E4-9a T . The DNA G+C content of strain E4-9a T was 29 mol%. Based on the results of DNA-DNA hybridization and phenotypic data, it appears that strain E4-9a T represents a novel species of the genus Lacinutrix, for which the name Lacinutrix himadriensis sp. nov. is proposed. The type strain is E4-9a T (5CIP 110310 T 5KCTC 23612 T ).

A yellow-coloured, rod-shaped, Gram-reaction-negative and aerobic bacterial strain, designated JC2675T, was isolated from a seawater sample from Jeju Island, Korea. The isolate required sea salts for growth. Gliding motility was observed. Flexirubin-type pigments were absent. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain JC2675T represented a distinct phyletic line that reflected a novel generic status within the family Flavobacteraceae with relatively low gene sequence similarities (<95.7 %) to other recognized genera. The predominant isoprenoid quinone (MK-6) and DNA G+C content (30 mol%) were consistent with the assignment of the novel strain to the family Flavobacteriaceae, but overall phenotypic traits demonstrated that the novel strain was not closely affiliated with any previously described genus. Based on data from a study using a polyphasic taxonomic approach, it is proposed that strain JC2675T represents a new genus and novel species belonging to the family Flavobacteriaceae, for which the name Pontirhabdus pectinivorans gen. nov., sp. nov. is proposed. The type strain of the type species is JC2675T ( = KACC 14153T = JCM 17107T).
