Article Abstract
Nitrous oxide (NO) is a potent greenhouse gas and has significantly increased in the atmosphere. Deep-sea hydrothermal fields are representative environments dominated by mesophilic to thermophilic members of the class that possess clade II encoding nitrous oxide reductase. Here, we report a strain HRV44 representing the first thermophilic campylobacterium capable of growth by H oxidation coupled to NO reduction. On the basis of physiological and genomic properties, it is proposed that strain HRV44 (=JCM 34002 = DSM 111345) represents a novel species of the genus , sp. nov. The comparison of the NO consumption ability of strain HRV44 with those of additional and other campylobacterial strains revealed the highest level in strain HRV44 and suggests the NO-respiring metabolism might be the common physiological trait for the genus . Our findings provide insights into contributions of thermophilic to the NO sink in deep-sea hydrothermal environments.

A novel bacterium, strain MOT50, was isolated from the chimney structure at the Iheya North field in the Mid-Okinawa Trough. The cells were motile short rods with a single polar flagellum. Growth was observed between 40 and 65 ℃ (optimum, 52 ℃), at pH values between 5.
