摘要: Lateral gene transfer (LGT) is an important evolutionary process in microbial evolution. In sewage treatment plants, LGT of antibiotic resistance and xenobiotic degradation-related proteins has been suggested, but the role outside these processes unknown. Microbial communities involved Enhanced Biological Phosphorus Removal (EBPR) have used to treat wastewater last 50 years may provide insights into adaptation engineered environment. We introduce two different types analysis identify EBPR communities, based on identifying assembled sequences with more than one strong taxonomic match, unusual phylogenetic patterns. applied methods investigate six energy-related metabolic pathways. The analyses identified overlapping non-identical sets transferred enzymes. All were homologous from known mobile genetic elements, many also close proximity transposases integrases data set. method had higher sensitivity method, potential LGTs. Both putative five enzymes within Australian community, a Danish none US-derived culture. Our able or compositional properties as candidate events. association candidates elements supports hypothesis transfer. results our strongly suggest that influenced development functionally pathways systems, transfers be unique each community due operating conditions composition.
