L. ferrooxidans cultivated in the presence of glucose, arabinose and acetate. L. ferrooxidans was cultivated in Mckintosh medium with 2% (w/v) iron sulfate (closed diamonds ♦), or 2% iron sulfate supplemented with 0.1% glucose (open circles ), 0.1% arabinose (closed circles ), or 1 mM acetate (closed triangles ▲), and the growth monitored by measuring iron oxidation at OD410 nm. All the cultures were inoculated with 1.9 × 105 cells ml-1. After 48 h, the cell number clearly increased (dashed lines) with respect to the starting inoculums (1.9 × 105 cells ml-1).
