Cultivation and metabolic versatility of novel and ubiquitous chemolithoautotrophic <i>Campylobacteria</i> from mangrove sediments.

ABSTRACT: Chemolithoautotrophic members from the Campylobacteria class are dominant key players in sulfidic habitats, where they make up a stable portion of sulfide-oxidizing bacterial communities. Nevertheless, few isolates have so far been cultivated and studied in situ, and most are derived from chemosynthetic ecosystems, limiting our understanding of their physiological and metabolic features as well as ecological roles in the global marine environments. In this study, seven potentially new species were successfully isolated from mangrove sediments and further diverged into three potentially new genera within the class Campylobacteria. These isolates were obligate chemolithoautotrophs that could grow through hydrogen oxidation as well as sulfur oxidation, reduction, and disp
