A Gram-stain-negative, red pigment-producing, aerobic, and rod-shaped bacterial strain (A2-2 T ) was isolated from a bleached scleractinian coral ( Porites lutea ). Strain A2-2 T grew with 1.0-7.0 % (w/v) NaCl (optimum, 3.0 %), at pH 6.0-11.0 (optimum, pH 8.0), and at 18-41 °C (optimum, 35 °C). Results of phylogenetic analysis based on 16S rRNA gene sequences suggested that strain A2-2 T fell within the genus Spartinivicinus and was closely related to Spartinivicinus ruber S2-4-1H T (98.1 % sequence similarity) and Spartinivicinus marinus SM1973 T (98.0 % sequence similarity). The predominant cellular fatty acids of strain A2-2 T were C 16 : 0 (31.0 %), summed feature 3 (29.0 %), summed feature 8 (11.7 %), C 12 : 0 3-OH (6.4 %), and C 10 : 0 3-OH (5.5 %), while the major respiratory quinone was Q-9. The polar lipids mainly comprised phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, and an unidentified phospholipid. The genome size of strain A2-2 T was 6.8 Mb, with a G+C content of 40.2 mol%. The DNA-DNA hybridization value was 24.2 % between A2-2 T and S. ruber S2-4-1H T and 36.9 % between A2-2 T and S. marinus SM1973 T , while the average nucleotide identity values were 80.1 and 88.8 %, respectively. Based on these findings, strain A2-2 T could be recognized to represent a novel species of the genus Spartinivicinus , for which the name Spartinivicinus poritis sp. nov. is proposed. The type strain is A2-2 T (=MCCC 1K08228 T =KCTC 8323 T ).

A Gram-stain-negative, aerobic, rod-shaped, nonmotile and yellow-pigmented bacterium designated E7-10 T was isolated from a bleached scleractinian coral Porites lutea . Strain E7-10 T grew with 1.0-8.0 % (w/v) NaCl (optimum, 4.0 %), at 18-41 °C (optimum, 28 °C) and at pH 6.0-10.0 (optimum, pH 8.0). Phylogenetic analysis using 16S rRNA gene sequences revealed that E7-10 T formed a lineage within the genus Hoeflea , but it was distinct from the closest species ' Hoeflea prorocentri ' PM5-8 T , showing 98.01 % sequence similarity. The predominant cellular fatty acids of E7-10 T were summed feature 8 (26.7 %), C 18 : 1  ω 7 c 11-methyl (26.2 %), C 16 : 0 (20.8 %) and C 19 : 0 cyclo ω 8 c (17.9 %). The major respiratory quinone was Q-10. The polar lipids mainly comprised phosphatidylethanolamine, two glycolipids and five phospholipids. The genome size of E7-10 T was 5.58 Mb with G+C content 60.27 mol%. The digital DNA-DNA hybridization and average nucleotide identity values between the genomes of strains E7-10 T and PM5-8 T were 19.50 and 75.95 %, respectively, which were both below the defined cutoff values (70 % and 95-96 %, respectively) for species delimitation. Thus, strain E7-10 T represents a novel species within the genus Hoeflea , for which the name Hoeflea poritis sp. nov. is proposed. The type strain is E7-10 T (=JCM 35852 T =MCCC 1K08229 T ).
