Unraveling anaerobic indole degradation in an acclimated sludge consortium: Candidate pathways and microbial division of labor inferred from metagenomic and metatranscriptomic analyses.
A long-term acclimated anaerobic sludge consortium and combined degradation assays, metabolite profiling, metatranscriptomics, and genome-resolved metagenomics are established to investigate the functional basis of anaerobic indole degradation and establish a stable anaerobic indole-degrading consortium.
