* = growth could not be determined via turbidity because inoculum itself was turbid. † = growth could not be determined because Fe oxides that are part of media are very turbid, and changes in turbidity due to cell growth were impossible to detect by eye. ‡ = turbidity was apparent but may have been due to inoculum (this was only culture experiment inoculated with a rock chip, which likely had particles on it to begin with). + = only one vial was positive, – = no growth.
