Abstract

The family Xanthobacteraceae, established in 2005 on the basis of 16S rRNA phylogeny, is affiliated with the Alphaproteobacteria. Currently (May 2012) it encompasses 7 genera (Xanthobacter [type genus], Ancylobacter, Azorhizobium, Labrys, Pseudolabrys, Pseudoxanthobacter, and Starkeya) and 28 species. All members grow as aerobic chemoheterotrophs, but facultative chemolithoautotrophy with hydrogen and/or reduced sulfur compounds is found in many species. Nitrogen fixation is widespread; the genus Azorhizobium entirely consists of N2-fixing symbionts that live in association with leguminous plants. Some species can grow on unusual substrates such as alkenes, halogenated aliphatic and aromatic compounds, terpenes, thiophenes, or polyaromatic compounds. Representatives of the family can be found worldwide in freshwater lakes and streams, soils, wetlands, and in polluted sites.
