Description of Gemmobacter aestuarii sp. nov., isolated from estuarine surface water and reclassification of Cereibacter changlensis as Gemmobacter changlensis Chen et al. 2013. Arch Microbiol. 2020 Jan 16;: Authors: Hameed A, Shahina M, Lin SY, Chen WM, Hsu YH, Lai WA, Young CC Abstract A Gram-stain-negative, tyrosine-metabolizing, non-motile, strictly aerobic, non-spore-forming, rod-shaped marine bacterium, designated strain CC-PW-75T, was isolated from the estuarine water off Pintung, Taiwan. Strain CC-PW-75T formed a distinct phyletic lineage associated with Gemmobacter species, sharing the highest 16S rRNA gene sequence similarity with G. megaterium CF17T and G. straminiformis CAM-8T (96.0% each) followed by G. aquatilis IFAM 1031T and G. nectariphilus AST4T (95.8% each). Analysis of the draft genome (3.76 Mbp) revealed the presence of genes encoding light-harvesting complexes, photosynthetic reaction centers and proteins involved in the metabolism of CO, CO2, HCO3‒ and H2S. However, bacteriochlorophyll a was not detected. Average nucleotide identity values between the genome sequence of CC-PW-75T and the related Gemmobacter species (n = 6) were estimated to be 72.8-76.3%. Polar lipid analysis revealed the presence of phosphatidylglycerol, phosphatidylethanolamine and an unidentified lipid in major amounts, and phosphatidylmonomethylethanolamine, phosphatidylcholine, an unidentified aminolipid and an unidentified lipid in...
