Abstract

Nuclepore polycarbonate filters floating on a liquid, FeSO 4 -containing medium (pH 1.6) were used to isolate a moderately thermophilic bacterium from a pyrite-oxidizing enrichment culture. The isolate failed to grow on any of the conventional solid media tried. To test the general applicability of the method, the enumeration of a fastidious acidophilic organism, Thiobacillus ferrooxidans , was carried out and the results compared with those obtained with other filters, solid media, and the most probable number technique. T. ferrooxidans showed better viability on the floating polycarbonate filters and grew in a much shorter time (4 to 5 days) than with the other techniques.
