Growth rates for strain HR11 grown over its ranges of temperature (A), pH (B) and NaCl concentration (C). Strain HR11 was grown in 10 ml of modified DSM 282 medium in sealed Balch tubes, with 1 g l−1 S2O32− as the electron acceptor and 2 atm 80:20 H2:CO2 headspace, and growth determined via cell counts on a Petroff–Hausser chamber. Error bars represent 95% confidence intervals.
