Analysis of Methanogen Communities in Anaerobic Membrane Bioreactors and Conventional Anaerobic Digester Systems

D. Hufnagel, S. Chang, J. Zhang & R. Lu · Journal of Advances in Biology & Biotechnology · 2015

Aims: Methanogenesis is the terminal step in anaerobic digestion and is often rate-limiting and highly sensitive to environmental changes. The performance of engineered anaerobic digesters depends on methanogenesis, which is often measured indirectly through methane production an...

Characterization of Proton Binding Properties of Extracellular Polymeric Substances in an Expanded Granular Sludge Bed Using Linear Programming Analysis

Y. Liu, S. Chang, F. M. Defersha, Q. Guo & R. Chen · Journal of Advances in Biology & Biotechnology · 2015

Aims: Extracellular polymeric substances (EPS) produced in biological wastewater treatment processes are from substrate metabolisms and biomass decay and mainly consist of proteins, polysaccharides, and nucleic acids. The chemical functional groups associated with these polymeric...
