 It is an aerobe that uses the menaquinone MK-7 in its electron transport chain.Marine myxobacteria are relatively uncommon compared to terrestrial myxobacteria.Studies of the salt adaptation of marine myxobacteria have found that "P pacifica" accumulates exogenous amino acids from its environment as osmoprotectants, in contrast with "E. salina", which expresses genes for the synthesis of endogenously produced betaine, ectoine, and hydroxyectoine.
