Growth of the isolates was optimal at 28–30 °C, pH 7.0–7.5 and with 2–3 % (w/v) NaCl. Both strains contained Q-8 as the sole respiratory quinone. The major cellular fatty acids in strain Z1T were C18 : 1ω7c, C16 : 0 and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH). The predominant polar lipids in strain Z1T were phosphatidylethanolamine, phosphatidylglycerol and an aminolipid. The genomic DNA G+C content of both strains was 45.1 mol%. Strains Z1T and JL1 were closely related, with 99.9 % 16S rRNA gene sequence similarity. The average nucleotide identity (ANI) value between strains Z1T and JL1 was 99.3 %. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strains Z1T and JL1 form a distinct phyletic line within the class Gammaproteobacteria, with less than 92.3 % similarity to their closest relatives. Based on data from the current polyphasic study, the isolates are proposed to belong to a novel species of a new genus designated Marinagarivorans algicola gen. nov., sp. nov. The type strain of the type species is Z1T ( = ATCC BAA-2617T = CICC 10859T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.000925
