  • a Growth in CSB medium with 2 to 3 mM sulfide for temperature tests and 1 mM sulfide for salinity and pH tests. All tests were run in triplicate except where noted in the text.

  • b ND, not determined; +, growth; −, no growth.

  • c Complete oxidation of sulfide was noted in only one of two replicates.
