Figure 2a
The flasks of OxiTop AN measuring system with PCBs of WEEE in growth medium inoculated with ARGCON5 and with growth medium and inoculum, 100th day of experiment. The flask with PCBs of WEEE is remarkably darker.

Figure 2b
The flasks of OxiTop AN measuring system with PCBs of WEEE in growth medium inoculated with ARGCON5 adapted to e-waste, with growth medium and inoculum only and with PCBs of WEEE in growth medium (without inoculum), 10th day of experiment. In the flask with all components added, gas bubbles indicate degradation of organic matter.
