[2][5] This organism has an average genome currently sized 3.8 mega base pairs (Mbp) containing 56.96% GC's, or guanine and cytosine content.

[7] H. meridiana is a commensal marine bacteria that is found living on reef-building corals as part of their surface microbiome.

Halomonas meridiana is a heterotrophic organism capable of anaerobic growth with the aid of glucose when nitrogen is not present.

[2] Many species of microorganisms and several strains of what would later be identified as Halomonas meridiana were found and tested for physical and chemical characteristics using quantitative phylogenetic techniques.

[2] In addition to Antarctica, Halomonas meridiana was also isolated from the host of organisms found living in and on coral, Acropora, across the world.

[7] The alkaline proteases are important aspects of the processes involving detergents, leather, food, and silk for consumer consumption.

[2] Halotolerant and halophilic bacteria, like H. meridiana can also provide valuable information about species that have been adapted to the salt lakes in cold temperatures as well as retaining the ability to live in symbiosis with other organisms.
