Microbial Adaptation in Fixed Submerged Bed Biofilms Under Extreme Conditions

Abstract

Microbial adaptation in fixed submerged bed biofilms under extreme conditions is key to the effective treatment of wastewater, which comes from diverse sources such as domestic, industrial and agricultural. These waters have varied compositions that present challenges for their proper management. Biofilms formed by microorganisms in fixed submerged beds allow for the degradation of contaminants, but extreme conditions such as elevated temperatures, fluctuating pH and the presence of toxic contaminants can affect their effectiveness.

Microorganisms in biofilms adapt to these conditions through metabolic changes, genetic alterations and modifications in the biofilm structure, which ensures their survival and efficiency in treatment. A comprehensive approach that classifies wastewater according to its origin and composition, and that considers microbial adaptation mechanisms, is essential to develop more effective and sustainable solutions in wastewater management, protecting both public health and the environment.
