Analysis of the representative genome (GCF_000152805.1) for Maritimibacter alkaliphilus confirmed this species as distinct from its closest relatives, with all ANI comparisons being <80% and 16S rRNA gene identity values being <97%.POCPu values >50% were obtained to neighbouring genera (Celeribacter persicus, 54.6%; Roseibacterium elongatum, 54.2%), however GTDB and 16S rRNA gene identity values confirm this species as a member of the genus Maritimibacter. Ecological analysis of 1,000 16S rRNA gene amplicon samples from different ecosystems identified Maritimibacter alkaliphilus as being most prevalent (53.2%) in coral metagenomes, where it was had the highest relative abundance (2.02%). Genome analysis predict the presence of metabolic modules for the utilisation of mannose, degradation of amino acids (aspartate, alanine, glycine, isoleucine, leucine, methionine, proline, cysteine, glutamate, arginine), along with production and utilisation of lactate.
