  1. a Toluene dosage in liquid culture was dosed from a secondary oil-phase, whereas in soils and APM it was dosed through the gas phase
  2. bmax pop size = mean maximum population size (CFU g− 1 for solid matrix, and CFU ml− 1 for liquid suspension); μmax = mean maximum growth rate ± stdev (h− 1, n = 3); G = generation time (h). N = estimated mean number of generations of growth
  3. cAPM Artificial porous matrix
  4. dSingle replicate because of insufficient material. Jonction here is 100%
