Removal of heavy metals and antibiotics from treated sewage effluent by bacteria.

Abstract

The increased loads of antibiotics and heavy metals in sewage leads to bacteria cells acquiring resistance to both heavy metals and antibiotics. Therefore, these bacteria can play an important role for removal of pollutants from sewage. the utilization of the microbial processes such as biosorption and enzymatic biodegradation processes has significantly inexpensive and eco-friendly. enzymatic techniques known has white biotechnology have the ability to degrade complex compounds Hence, these can be applied to industrial processes. in the current review, the removal of heavy metals and antibiotics from treated sewage effluents by heavy metal/antibiotic resistant bacteria will be discussed.
