Analysis of growth was determined by shaking the vials. If turbidity was greater than in the initial sample, growth was considered positive. ++ = both vials were positive, + = one vial was positive, – = no growth. ND = not determined (media targeting iron reducers and iron oxidizers contain particulates, and therefore a change in turbidity was impossible to detect).
