[Gram-negative eubacteria isolated from the water, molluscs and algae of the Black Sea].

Microorganisms strains (384) have been isolated from water, algae and molluscs collected in the Karadag reserve and the village of Katsiveli (Black Sea shore of the Crimea); 81 of the above strains are gram-negative oxidase-positive rods which require sodium ions for their growth. A group of nonfermenting mobile bacteria deprived of arginine dihydrolase have been distinguished among the latter; as to their physiological and biochemical properties and sensitivity to some antibiotics these bacteria were referred to Alteromonas, Marinomonas, Pseudoalteromonas genera.
