Rheinheimera sediminis sp. nov., a marine bacterium isolated from coastal sediment. Int J Syst Evol Microbiol. 2019 Dec 04;: Authors: Yu Q, Qi Y, Zhang H, Pu J Abstract A Gram-stain-negative, aerobic, rod-shaped bacterium, designated strain YQF-1T, was isolated from coastal sediment in Jiangsu Province (PR China) and characterized phylogenetically and phenotypically. Bacterial optimal growth occurred at 28 °C (range 4-40 °C) and pH 7 (range pH 6-11). Phylogenetic analysis based on 16S rRNA gene sequence indicated that YQF-1T was related to members of the genus Rheinheimera and shared the highest sequence identities with Rheinheimera mesophila DSM 29723T (98.5 %), followed by Rheinheimera tangshanensis DSM 19460T (98.4 %), Rheinheimera tilapiae Ruye-90T (97.9 %), Rheinheimera soli BD-d46T (97.9 %), Rheinheimera aquatica GR5T (97.4 %), Rheinheimera coerulea TAPG2T (97.3 %) and Rheinheimera texasensis A62-14BT (97.1 %). The 16S rRNA gene sequence identities between YQF-1T and other members of the genus Rheinheimera were below 97.0 %. The digital DNA-DNA hybridization value between YQF-1T and Rheinheimera mesophila DSM 29723T was 25.1±2.3 %. The average nucleotide identity (ANI) value between YQF-1T and Rheinheimera mesophila DSM 29723T was 81.4 %. The major respiratory quinone was Q-8. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, phospholipid, two unidentified aminolipids and thr...
