As a very important technique for spreading ARG, In addition to the capable bacterial receiver, a donor is needed to deliver the ARG for transfer. Given that numerous ARG carriers with biological activity will be introduced with the killed donors in the chlorination process [24], which would add to escalating eARG following disinfection [25], it's been hypothesised that the chlorination process would greatly enhance iARG abundance by advertising the uptake of produced ARG and genetic transformation across germs. On top of that, culturable chlorine-injured micro organism might Perform roles During this process.
