Table 2 Indicator genera significantly associated with pyrene treatment in the soil-compost mixture at day 48 and in fertilized soil at day 46, using group-equalized point-biserial correlation coefficients (Phi coefficient) computed from genera relative abundance data derived from 16S rDNA amplicon libraries from extracted DNA and from RNA (cDNA) for comparison, with indication of the significance p value
