Abstract Gram-stain-negative, aerobic, non-flagellated strains 172403-2T and BT310T were isolated from the soil collected in Pyeongchang city and Uijeongbu city, Korea. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strains 172403-2T and BT310T formed a distinct lineage within the family Hymenobacteraceae (order Chitinophagales, class Chitinophagia) and were most closely related to members of the genus Pontibacter, Pontibacter chitinilyticus 17gy-14T (95.7%), and Pontibacter populi HLY7-15T (97.1% 16S rRNA gene sequence similarity) respectively. The optimal growth of strains 172403-2T and BT310T occurred at pH 7.0, in the absence of NaCl, and 25°C and 30°C, respectively. The predominant cellular fatty acids were iso-C15:0 and summed feature 4 (iso-C17:1 I / anteiso-C17:1 B). The major respiratory quinone of the two strains was MK-7. The major polar lipid of the two strains was phosphatidylethanolamine. Biochemical, chemotaxonomic and phylogenetic analyses indicated that strains 172403-2T and BT310T represent novel bacterial species within the genus Pontibacter, for which the names Pontibacter rubellus and Pontibacter situs are proposed. The type strains of Pontibacter rubellus and Pontibacter situs are 172403-2T and BT310T, respectively.

An aerobic, yellow-pigmented, bacteriochlorophyll a-producing strain, designated AAP5 (=DSM 111157=CCUG 74776), was isolated from the alpine lake Gossenköllesee located in the Tyrolean Alps, Austria. Here, we report its description and polyphasic characterization. Phylogenetic analysis of the 16S rRNA gene showed that strain AAP5 belongs to the bacterial genus Sphingomonas and has the highest pairwise 16S rRNA gene sequence similarity with Sphingomonas glacialis (98.3%), Sphingomonas psychrolutea (96.8%), and Sphingomonas melonis (96.5%). Its genomic DNA G + C content is 65.9%. Further, in silico DNA-DNA hybridization and calculation of the average nucleotide identity speaks for the close phylogenetic relationship of AAP5 and Sphingomonas glacialis. The high percentage (76.2%) of shared orthologous gene clusters between strain AAP5 and Sphingomonas paucimobilis NCTC 11030T, the type species of the genus, supports the classification of the two strains into the same genus. Strain AAP5 was found to contain C18:1ω7c (64.6%) as a predominant fatty acid (>10%) and the polar lipid profile contained phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, sphingoglycolipid, six unidentified glycolipids, one unidentified phospholipid, and two unidentified lipids. The main respiratory quinone was ubiquinone-10. Strain AAP5 is a facultative photoheterotroph containing type-2 photosynthetic reaction centers and, in addition, contains a xathorhodopsin gene. No CO2-fixation pathways were found.
