Comparative study of microbial functional repertoire and gene expression alterations under chlorination in contrasting effluent types

Metagenomics and metatranscriptomics analyses were used to compare the gene abundance and expression of the microbiomes before and after chlorination in two contrasting types of treated effluents. One of the effluents received saline influents from coastal regions using seawater for flushing, with chemically enhanced primary treatment applied before chlorination. The other type of effluent received freshwater-based influents and underwent secondary treatment before chlorination. We aim to explore a wide range of survival strategies adopted by microbiomes under chlorination and compare their characteristics in each type of effluents.
