The growth range of NaCl concentration was 0.5–10.0 % (w/v), with an optimum at 2.5–3.0 % (w/v), the temperature range for growth was 10–40 °C, with an optimum at 28–30 °C, the pH range for growth was pH 6.0–9.5, with an optimum at pH 7.5. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain ZQ330T exhibited less than 97.0 % sequence similarity to all type strains with validly published names and revealed that strain ZQ330T formed a distinct lineage in the genus Idiomarina . The average nucleotide identity, and in silico DNA–DNA hybridization values between strain ZQ330T and the reference strains were 64.8–69.9 % and 27.5–28.4 %, respectively. Chemotaxonomic analysis indicated that the main respiratory quinone was Q-8, the predominant cellular fatty acids were iso-C15 : 0, iso-C17 : 0, summed feature 9 (C16 : 0 10-methyl and/or iso-C17 : 1ω9c), iso-C15 : 1F, C16 : 0, C18 : 0, summed feature 3 (C16 : 1ω8c and/or iso-C16 : 1 2-OH) and summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c). The polar lipid profile was composed of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, an unidentified glycolipid, an unidentified aminolipid, an unidentified phospholipid and two unidentified lipids. Based on the genotypic, phenotypic, chemotaxonomic and phylogenetic features, strain ZQ330T is considered to represent a novel species, for which the name Idiomarina mangrovi sp. nov. is proposed. The type strain is ZQ330T (=MCCC 1K03495T=KCTC 62455T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.003372
