| Study Title | Identifying Biodegradation Pathways of Cetrimonium Bromide (CTAB) Using Metagenome, Metatranscriptome, and Metabolome Tri-omics Integration |
| Study Summary | Traditional research on biodegradation of emerging organic pollutants involves slow and labor-intensive experimentation. Currently, fast-developing metagenome, metatranscriptome, and metabolome technologies promise to expedite mechanistic research on biodegradation of emerging organic pollutants. Integrating the metagenome, metatranscriptome, and metabolome (i.e., tri-omics) makes it possible to link gene abundance and expression with the biotransformation of the contaminant and the formation of metabolites from this biotransformation. In this study, we used this tri-omics approach to study the biotransformation pathways for cetyltrimethylammonium bromide (CTAB) under aerobic conditions. The tri-omics analysis showed that CTAB undergoes three parallel first-step mono-/di-oxygenations ; intermediate metabolites and expressed enzymes were identified for all three pathways, and the beta-carbon mono-/di-oxygenation is a novel pathway. Four metabolites – palmitic acid, trimethylamine N-oxide (TMAO), myristic acid, and betaine – were the key identified biodegradation intermediates of CTAB, and they were associated with first-step mono-/di-oxygenations This tri-omics approach with CTAB demonstrates its power for identifying promising paths for future research on the biodegradation of complex organics by microbial communities. |

| Treatment Summary: | Reactors are set under different conditions: composite membrane (MR) or polypropylene membrane (PP). The biofilms were treated under different conditions: A: with "160mg/L CTAB + 3g/L NH4+, low O2 pressure", B: "160mg/L CTAB + 3g/L NH4+, high O2 pressure", C:" 160mg/L CTAB, high O2 pressure", D:"400mg/L CTAB, high O2 pressure". |
