A facultatively anaerobic organoheterotroph, designated JAM-BA0302(T), was isolated from a deep subseafloor sediment at a depth of 247.1 m below the seafloor off the Shimokita Peninsula of Japan in the north-western Pacific Ocean (Site C9001 , water depth 1180 m). Cells of strain JAM-BA0302(T) showed gliding motility and were thin, long rods with(More)
Two aerobic methane-oxidizing bacterial strains were isolated from distinct marine environments in Japan. Strains IT-4(T) and T2-1 were Gram-stain-negative, aerobic, motile, plump short rods or oval-shaped bacteria with a single polar flagellum and type I intracytoplasmic membranes. They were obligate methanotrophs that grew only on methane or methanol.(More)
A novel methane-oxidizing bacterium, strain IT-9(T), was isolated from a shallow submarine hydrothermal system occurring in a coral reef in Japan. Strain IT-9(T) was a Gram-negative, aerobic, motile, coccoid or oval-shaped bacterium with the distinctive intracytoplasmic membrane arrangement of a type I methanotroph. Strain IT-9(T) was a moderately(More)
A novel methane-oxidizing bacterium, strain HTM55(T), was isolated from subsurface hot aquifer water from a Japanese gold mine. Strain HTM55(T) was a Gram-negative, aerobic, motile, coccoid bacterium with a single polar flagellum and the distinctive intracytoplasmic membrane arrangement of a type I methanotroph. Strain HTM55(T) was a moderately(More)
UNLABELLED It has been suggested that iron is one of the most important energy sources for photosynthesis-independent microbial ecosystems in the ocean crust. Iron-metabolizing chemolithoautotrophs play a key role as primary producers, but little is known about their distribution and diversity and their ecological role as submarine iron-metabolizing(More)
The reef-building (hermatypic) corals build the structural foundation of coral reefs in tropical and subtropical zones, and form the trophic basis of coral reef ecosystems. These corals are symbiotic complexes of the cnidarian host, mostly of the order Scleractinia, and dinoflagellate endosymbionts Symbiodinium spp. Most hermatypic corals form colonies, and(More)
A novel psychrophilic, marine, bacterial strain designated BJ-1(T) was isolated from the Iheya North hydrothermal field in the Okinawa Trough off Japan. Cells were Gram-negative, rod-shaped, non-spore-forming, aerobic chemo-organotrophs and motile by means of a single polar flagellum. Growth occurred at temperatures below 16 °C, with the optimum between 9(More)
We examined the genotypic diversity of the large population of Heliopora coerulea, discovered recently in Ooura Bay, northern Okinawa Main Island Japan, together with another large population in Shiraho Reef, also in southwest Japan, using 9 polymorphic microsatellite markers. From each population, 40 samples were systematically collected along 2 transect(More)
