A mixture of FAMEs (Supelco, nr. 47080-U and 47885-U) [http://www.selleckchem.com/products/loxo-101.html LOXO-101] was used as a qualitative standard. An internal standard (19:0) was used for calculation of FAME concentrations, as well as for correction of ��13C values. ��13C values of PLFAs were also corrected for ��13C values of the C added during methanolysis. We used the sum of the fatty acids i15:0, a15:0, i16:0, i17:0, a17:0 as indicator of Gram-positive bacteria, the sum of 16:1��9, 16:1��7, 18:1��7, 18:1��5, cy17:0, cy19:0, cy18:0 as indicator of Gram-negative bacteria, and all these together with 17:0, 17:1��6, 17:1��7 as a measure for total bacteria. The quantity of 18:2��6,9 was used as an indicator of fungal biomass (Kaiser et?al., 2010a). We estimated 13C incorporation into microbial biomass by calculating the weighted average ��13C value of PLFAs and multiplying it with the amount of microbial biomass C, keeping in?mind that ��13C values may vary between different cell components. Data were transformed prior to analysis to achieve normality and homogeneity of variances (natural logarithmic transformation was applied for absolute concentrations and process rates, square root transformation for relative values). Characteristics of the three [https://en.wikipedia.org/wiki/Tuclazepam tuclazepam] soils were compared by one-way ANOVA. Multivariate statistics were performed with standardized data. We applied a principal component analysis (PCA) and analysis of similarity (ANOSIM), which is a permutation-based test, to evaluate differences in the functional response of microbial communities [http://www.selleckchem.com/products/bms-911543.html BMS-911543 mouse] to substrate addition. Relative values of microbial processes, C and N pools and microbial groups in percent of control incubations were analyzed for differences from 100% using student's t-test. Apart from significance level p?
