Percent removal and dechlorination of PCB homologues in myco-augmented microcosms and respective controls. Removal (%) of PCB homologue groups in the PCB-contaminated soil after bioremediation at 28°C for 60 d in the incubation control and Lentinus tigrinus microcosms in the absence (i.e., ICM and Lt M respectively) and in the presence of 2.5% (w/w) soybean oil (i.e., ICSOM and Lt SOM). Data are means ± standard deviations (error bars) of two replicated experiments. Multiple pair-wise comparisons were performed by the Tukey test (P < 0.05). Same lower case and upper case letters denote absence of statistical significance between supplementation-dependent changes within the same PCB-homologue group and between PCB-homologue groups for the same treatments, respectively. The overall PCB percent removals were as follows: ICM, 27.8 ± 0.07; ICSOM, 24.5 ± 0.03; Lt M, 33.6 ± 0.32 and Lt SOM, 26.9 ± 0.06. The inset plot reports the percent release of organic contaminant-bound chloride (PROCBC), calculated according to Brinkman and de Kok [34].
