 Ocean’s surface water is characterized by a high concentration of hydrogen .In 1989, for the first time, an aerobic hydrogen oxidizing bacteria was isolated from sea water and the discovery of this strain was very important also because for the first time a hydrogen oxidizing bacteria was identified in normal temperature conditions.Experimentally it has been shown that the MH-110 strain is able to grow in an atmosphere (under a continuous gas flow system) characterized by an oxygen concentration of 40% (analogous characteristics are present in the surface water from which the bacteria were isolated, which is, in fact, a fairly aerated medium).
