Table 2: Enzymatic activities (total hydrolase, dehydrogenase, lactose, versatile peroxidase, Mn-peroxidase) and ergosterol content of the control microcosms (C), and microcosms inoculated with SMS of _P. eryngii_ (Pe), _L. edodes_ (Le), _P. ostreatus_ (Po) and _A. bisporus_ (Ab) at the end of the incubation. Data are presented as mean values \(\pm\) standard deviation (\(n=3\)). Same letters indicate lack of statistically significant difference (\(p<\) 0.05) between treatments. n.d.: parameter not detected. \begin{table}

lower than the previous fractions. Finally, the heaviest fraction (>C\({}_{35}\)) was the less abundant, with a concentration two-folds lower than the most abundant aliphatic hydrocarbons. The control microcosms achieved the highest concentration for most of the aliphatic groups. In contrast, the bioaugmented microcosms improved the degradation of aliphatic hydrocarbons with all having significantly lower concentrations than control microcosms. Therefore, the four SMSs were useful to improve the aliphatic hydrocarbon's removal, excepting the heaviest fraction (>C\({}_{35}\)), for which no significant differences were found between the control and any of the bioaugmented microcosms. For fractions lower to C\({}_{35}\) significant differences were observed between the four bioaugmented treatments. _A. bisporus_ microcosms reached the lowest concentration of all the aliphatic groups except for the heaviest group (>C\({}_{35}\)). _L. edodes_ and _P. ostreatus_ treatments also achieved significantly higher degradation than control. _P. eryngii_ microcosms achieved significantly higher concentrations of C\({}_{10}\)-C\({}_{12}\), C\({}_{12}\)-C\({}_{16}\), C\({}_{16}\)-C\({}_{21}\) and C\({}_{21}\)-C\({}_{35}\) hydrocarbons than _A. bisporus_ microcosms. The most abundant aromatic hydrocarbons were EC\({}_{16}\)-EC\({}_{21}\).
