“…The fungi in BM and BMN soils still exhibited significant growth just in the first 4 d incubation, which was similar to the study of Andersson et al [25]. The autoclaving process facilitated the growth of the inoculated fungi in two ways.…”

“…Another important observation in our study is that fungal to bacterial PLFA ratios were within the range 0.01-0.48 following 56 days of continuous composting treatment, showing that fungi are an important microbial group in the in-vessel composting of contaminated soil [23,24], and that marked changes in microbial community structure occur during in-vessel composting following different temperature profiles. The data analysis indicated that the use of thermophilic temperatures towards the end of the in-vessel composting-bioremediation process in treatment TP2 resulted in a higher fungal to bacterial PLFA ratio and a lower G(+)/G(−) bacterial ratio.…”

“…The lack of inoculated fungal growth in these non-autoclaved columns could be explained by the inability of the fungus to compete with the indigenous soil microorganisms (Radtke et al, 1994;in der Wiesche et al, 1996;Martens and Zadrazil, 1998;Andersson et al, 2000). Surprisingly, the amount of fungal carbon was even higher in the control-medium columns compared to the Schizophyllum columns.…”

Weathering of ancient organic matter contributes significantly to biogeochemical carbon cycles over geological times. The principle role of microorganisms in this process is well recognized. However, information is lacking on the contribution of individual groups of microorganisms and on the effect of labile carbon sources to the degradation process. Therefore, we investigated the contribution of fungi, Gram-positive and Gram-negative bacteria in the degradation process using a column experiment. Investigations were performed on low metamorphic black slates. All columns contained freshly crushed, sieved (0.63-2 mm), not autoclaved black slates. Two columns were inoculated with the lignite-degrading fungus Schizophyllum commune and received a culture medium containing 13 C labeled glucose, two columns received only this culture medium and two control columns received only water.The total mass balance was calculated from all carbon added to the slate and the CO 2 and DOC losses. Phospholipid fatty acids (PLFA) were extracted to investigate microbial communities. We used both the compound specific 14 C and 13 C signal of the PLFA to quantify carbon uptake from black slates and the glucose of the culture medium, respectively.The total carbon loss in these columns exceeded the amount of added carbon by approximately 60%, indicating that black slate carbon has been used. PLFA associated with Gram-positive bacteria dominated the indigenous community and took up 22% of carbon from black slate carbon, whereas PLFA of Gram-negative bacteria used only 8% of carbon from the slates. PLFA of Gram-negative bacteria and fungi were both mostly activated by the glucose addition. The added Schizophyllum did not establish well in the columns and was overgrown by the indigenous microbial community. Our results suggest that especially Gram-positive bacteria are able to live on and degrade black slate material. They also benefit from easy degradable carbon from the nutrient broth. In natural environments priming due to root exudates might consequently enhance weathering.
