Abstract
A new species of Nitrosococcus is described. It resembles Nitrosococcus oceanus in shape, size, and ultrastructure of the cells. However, the new species has a more pronounced salt requirement, corresponding to its natural habitats. Two strains were isolated from a salt lake in Saudi Arabia and a salt lagoon in the Mediterranean Sea, respectively. In contrast to N. oceanus, both isolates of the new species were unable to utilize urea as ammonia source. Both species also differed in gelelectrophoretic cell protein patterns. The name N. halophilus is proposed.
