“…The genus Oceanisphaera was first described by Romanenko et al (2003) with Oceanisphaera litoralis as the type species. At the time of writing, the genus Oceanisphaera is comprised of six recognized species ( http://www.bacterio.net/m/oceanisphaera.html ): O. litoralis (Romanenko et al , 2003), Oceanisphaera donghaensis (Park et al , 2006), Oceanisphaera ostreae (Choi et al , 2011), Oceanisphaera sediminis (Shin et al , 2012), Oceanisphaera arctica (Srinivas et al , 2012) and Oceanisphaera profunda (Xu et al , 2014). Members of the genus are aerobic, psychrotolerant and moderately halophilic.…”

A novel aerobic, Gram-staining-negative bacterium, designated strain LAM-WHM-ZC T , was isolated from coastal sediment samples from the Bohai Sea, near Yantai, China. Cells of LAM-WHM-ZC T were non-motile, short-rod-or coccoid-shaped. The temperature and pH ranges for growth were 4-40 8C (optimum: 20-33 8C) and pH 5-9 (optimum: pH 7.5). The strain did not require NaCl for growth but tolerated up to 10 % NaCl (w/v). The major fatty acids of strain LAM-WHM-ZC T were summed feature 3, C 12 : 0 , C 16 : 0 , summed feature 2 and summed feature 8. The predominant respiratory quinone was ubiquinone Q-8. The main polar lipids were diphosphatidyglycerol, phosphatigylethanolamine, phosphatidyglycerol, one phospholipid and four unidentified glycolipids. The DNA G+C content was 59.3 mol% as determined by the melting temperature (T m ) method. Analysis of the 16S rRNA gene sequence indicated that the isolate represented a member of the genus Oceanisphaera and was closely related to Oceanisphaera arctica KCTC 23013 T , Oceanisphaera litoralis DSM 15406 T , Oceanisphaera sediminis KACC 15117 T and Oceanisphaera donghaensis KCTC 12522 T with 97.7 %, 97.1 %, 96.6 % and 96.6 % sequence similarity, respectively. The DNA-DNA hybridization values between strain LAM-WHM-ZC T and the four reference strains were 47.4¡2.8 %, 33.5¡2.2 %, 28.4¡1.8 % and 13.7¡0.8 %, respectively. Based on its phenotypic and genotypic properties, strain LAM-WHM-ZC T is suggested to represent a novel species of the genus Oceanisphaera, for which the name Oceanisphaera psychrotolerans sp. nov. is proposed. The type strain is LAM-WHM-ZC T (5ACCC 06516 T 5JCM 30466 T ).

“…Beta diversity analyses showed that the microbiomes of all external body sites were similar to those of the surrounding environment, and there were fewer statistically significant differences between the environmental samples and external body sites compared to internal body sites. Similarly, both environmental and external penguin samples were primarily dominated by the same phyla, including the bacterial genera Oceanisphaera and Psychrobacter, which have been associated with both planktonic 34 , 35 and host-associated marine microbiomes 36 , 37 . Together, these trends suggest that the external African penguin microbiome is strongly influenced, and likely influences, the microbiome of immediate surrounding environment, with transfer of microbes likely routinely occurring between these body sites and the water and various surfaces of the managed care exhibit.…”

Animals under managed care in zoos and aquariums are ideal surrogate study subjects for endangered species that are difficult to obtain in the wild. We compared the fecal and oral microbiomes of healthy, managed African penguins (Spheniscus demersus) to those of other domestic and wild vertebrate hosts to determine how host identity, diet, and environment shape the penguin microbiome. The African penguin oral microbiome was more similar to that of piscivorous marine mammals, suggesting that diet and a marine environment together play a strong role in shaping the oral microbiome. Conversely, the penguin cloaca/fecal microbiome was more similar to that of other birds, suggesting that host phylogeny plays a significant role in shaping the gut microbiome. Although the penguins were born under managed care, they had a gut microbiome more similar to that of wild bird species compared to domesticated (factory-farmed) birds, suggesting that the managed care environment and diet resemble those experienced by wild birds. Finally, the microbiome composition at external body sites was broadly similar to that of the habitat, suggesting sharing of microbes between animals and their environment. Future studies should link these results to microbial functional capacity and host health, which will help inform conservation efforts.

Strain S33(T) was isolated from oil-contaminated sediment of Tae-an coastal region of South Korea. Cells are aerobic, motile, Gram staining-negative, and coccoid shaped. Strain S33(T) grew optimally at the temperature of 25 °C (range of 4-40 °C), pH 6.0 (range of pH 6.0-10.0), and in the presence of 1 % (w/v) NaCl (range of 0-10 %). Ubiquinone-8 was the predominant respiratory quinone. C16:0, summed feature 3 (comprising C16:1ω7c/C16:1ω6c) and C18:1ω7c were the major fatty acids. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol. Strain S33(T) showed the ability to degrade benzene, toluene, and ethylbenzene after 3 days incubation. 16S rRNA gene sequence analysis showed that the strain S33(T) was most closely related to Oceanisphaera sediminis TW92(T) (97.3 %), Oceanisphaera profunda SM1222(T) (97.2 %), and Oceanisphaera ostreae T-w6(T) (97.1 %) and <97 % with other members of the genus Oceanisphaera. The genomic DNA G+C mol% content of strain S33(T) was 51.0 mol%. Based on distinct phenotypic, genotypic, and phylogenetic analysis, strain S33(T) was proposed to represent a novel species in the genus Oceanisphaera as Oceanisphaera aquimarina sp. nov. (= KEMB 1002-058(T) = JCM 30 794(T)).
