Blank cells indicate that no data are available with regard to the specific variable. Data for S. arsenophilum MIT-13T are from references 2, 57, and 71. Data for S. barnesii SES-3T are from references 41, 57, and 72. Data for Chrysiogenes arsenatis BAL-1T are from reference 47. Data for Desulfotomaculum auripigmentum OREX-4T are from reference 58. Data for Bacillus arseniciselenatis E1HT and Bacillus selenitireducens MLS10T are from reference 6. Data for Desulfomicrobium sp. strain Ben-RB are from reference 46. Data for Pyrobaculum arsenaticum PZ6T are from reference 33. +, growth was supported; −, growth was not supported.
Physiological characterization is minimal with no formal survey of electron donors or acceptors.
Growth occurs only in the presence of acetate as a carbon source.
Growth is fermentative rather than respiratory.
Growth is microaerophilic.
