Abstract

Two new methane-oxidizing bacteria have been isolated from seawater samples from Plymouth Sound. These marine methanotrophs have an obligate requirement for NaCl and exhibit many properties of typical Type I methanotrophs previously isolated from freshwater environments. However, they are different from all other methanotrophs thus far described in that they failed to grow on all solid media tested. The nitrogen metabolism of both strains was investigated. They were not N₂-fixers nor would they use ammonia as nitrogen source. They appeared to utilize the glutamate dehydrogenase pathway for the assimilation of ammonia under all growth conditions tested.
