Metaproteomics applied to activated sludge for industrial wastewater treatment revealed the dominance of Hyphomicrobium zavarzinii.

Abstract

Biological processes are considered the conventional treatment for wastewater since almost acentury. Different microbial populations often cooperate in the degradation of pollutants present inwastewater and they represent the biomass of the so-called activated sludge. Several tools weredeveloped for the characterization of these microbial consortia: microscopy, physicaldeterminations, respirometry, molecular tools. Improved understanding of microbial consortia inactivated sludge requires deep investigation including functional analysis. Metagenomics wasrecently applied to wastewater treatment plants. Technical advances in mass spectrometry (MS)enabled the proteome analysis of complex microbial communities in environmental samples suchas those of municipal wastewater treatments. In this work the metabolic behavior of the biomass ofa lab-scale plant treating industrial pharmaceutical wastewater was investigated.
