Hippea maritima DSM 10411

Hippea maritima (strain ATCC 700847 / DSM 10411 / MH2) is an obligate anaerobic, moderately thermophilic, sulfur-reducing, Gram-negative bacterium isolated from shallow-water hot vents of the Bay of Plenty (New Zealand) and Matupi Harbour (Papua New Guinea). Cells are short, motile rods with one polar flagellum. It grows optimally at temperatures between 52 and 54 degrees Celsius, between pH 5.8-6.2, and with 2.5-3% (w/v) NaCl. Growth substrates are molecular hydrogen, acetate and saturated fatty acids; one of the strains, isolated from Matupi Harbour, is able to utilize ethanol. Elemental sulfur is required for growth. H2S and CO2 are the only growth products. No growth occurs in the absence of 100 mg yeast extract I-1. (Adapted from PMID: 10425760). (HAMAP: HIPMA)
