The thiol concentrations (×10−6 mol L−1) for incubation at 180 h in the presence of bacteria (3). Control experiments were carried out where bacteria alone, without polymer, were incubated in phosphate buffer (1) and polymer was incubated with phosphate buffer (2). Mean ± SD, n = 6.

|---|---|---|---|---|
| Bacteria only (1) | 0.247 ± 0.131 | 0.401 ± 0.096 | 0.624 ± 0.082 | 0.848 ± 0.234 |
| Polymer only (2) | 4.800 ± 0.289 | 13.012 ± 1.402 | 23.120 ± 0.531 | 33.701 ± 0.696 |
| Bacteria + polymer (3) | 6.900 ± 0.416 | 17.100 ± 0.480 | 55.920 ± 1.980 | 118.600 ± 1.450 |
