Project description:The functional diversity of soil microbial communities was explored for a poplar plantation, which was treated solely with biogas slurry, or combined with biochar at different fertilization intensities over several years.
Project description:This experiment aimed to understand stress responses of microbial communities differing in chronic exposure to the photosynthesis inhibitor diuron, combining untargeted metatranscriptomics (RNA-seq) and dose-response design. First, river microbial communities were incubated for 5-weeks in microcosms 1/ under constant exposure to 4µg/L of diuron (stressed community) or 2/ without contamination (non-stressed community). Then, both communities were exposed for 1 hour to a gradient of diuron concentrations to investigate differences in stress responses after chronic exposure. This experimental design enabled the determination of contig response trends as well as sensitivity thresholds.
