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. |

Column Name: | Waters XBridge BEH Amide (150 x 2.1 mm, 2.5um) |
Column Temperature: | 40 |
Flow Gradient: | After the initial 1-min isocratic elution of 90% B, the percentage of Solvent B was gradually decreased to 40% at t = 11 min. The composition of Solvent B was maintained at 40% for 4 min (t=15 min), and then the percentage of B gradually went back to 90%, to prepare for the next injection. |
