Abstract

The family Hyphomicrobiaceae, first proposed in 1950, is affiliated with the Alphaproteobacteria. Currently (June 2012) it encompasses 18 genera: Hyphomicrobium [type genus], Ancalomicrobium, Angulomicrobium, Aquabacter, Blastochloris, Cucumibacter, Devosia, Dichotomicrobium, Filomicrobium, Maritalea, Methylorhabdus, Pedomicrobium, Pelagibacterium, Prosthecomicrobium, Rhodomicrobium, Rhodoplanes, Seliberia, and Vasilyevaea, with a total of 54 species. Morphologically and physiologically the family is highly diverse. Many representatives are characterized by the presence of prosthecae, and many species divide by budding. Many prosthecate species are oligocarbophilic, thriving only in the presence of low concentrations of suitable carbon sources and unable to grow in rich media. Most are aerobic chemoheterotrophs. A few representatives can grow anaerobically by denitrification or mixed-acid fermentation. Blastochloris, Rhodomicrobium, and Rhodoplanes are genera of facultative photoheterotrophs. Facultative chemolithotrophy with hydrogen and/or reduced sulfur compounds is also encountered. Representatives of the family can be found worldwide in soils, freshwater lakes and streams, and also in the marine environment.
