Microbial screening strategies for biodegradation of monocyclic phenolic compounds

摘要

Wastewaters discharged from oil refineries and coal coking plants often contain large amounts of toxic monocyclic phenolic compounds (MCPCs), mainly including phenol, cresols and xylenols, polluting soils and surface water. In this work, crude phenols or 12 individual MCPCs were used as the enrichment medium and the later strategy was discovered for the first time to be more effective in finding more and competent MCPC-degrading strains. Phylogenetic analysis and multiple MCPC degradation tests revealed that phylogenetically close microbes generally exhibited similar MCPC-degrading spectra.
