Arcobacter peruensis sp. nov., a Chemolithoheterotroph Isolated from Sulfide- and Organic-Rich Coastal Waters off Peru.

ABSTRACT: Members of the epsilonproteobacterial genus Arcobacter have been identified to be potentially important sulfide oxidizers in marine coastal, seep, and stratified basin environments. In the highly productive upwelling waters off the coast of Peru, Arcobacter cells comprised 3 to 25% of the total microbial community at a near-shore station where sulfide concentrations exceeded 20 μM in bottom waters. From the chemocline where the Arcobacter population exceeded 10⁶ cells ml^-1 and where high rates of denitrification (up to 6.5 ± 0.4 μM N day^-1) and dark carbon fixation (2.8 ± 0.2 μM C day^-1) were measured, we isolated a previously uncultivated Arcobacter species, Arcobacter peruensis sp. nov. (BCCM LMG-31510). Genom
