An anaerobic digester with microbial electrolysis cell enhances relative abundance of methylotrophic methanogens in bulk solution

Physiology of halophilic, methylotrophic methanogens

Physiology of Halophilic, Methylotrophic Methanogens. Priya Kadam, Ph. D. Oregon Graduate Institute of Science & Technology, 1996 Supervising Professor: David R. Boone Several methanogens of the family Melharzosarcir2aceae were characterized phenotypically and phylogenetically. Methanolobus bombayensis and Methariolobza ~ui'cai~i were characterized physiologically and taxonomically. The influen...

Enhanced methane production in an anaerobic digestion and microbial electrolysis cell coupled system with co-cultivation of Geobacter and Methanosarcina.

The anaerobic digestion (AD) and microbial electrolysis cell (MEC) coupled system has been proved to be a promising process for biomethane production. In this paper, it was found that by co-cultivating Geobacter with Methanosarcina in an AD-MEC coupled system, methane yield was further increased by 24.1%, achieving to 360.2 mL/g-COD, which was comparable to the theoretical methane yield of an a...

The presence of hydrogenotrophic methanogens in the inoculum improves methane gas production in microbial electrolysis cells

High current densities in microbial electrolysis cells (MECs) result from the predominance of various Geobacter species on the anode, but it is not known if archaeal communities similarly converge to one specific genus. MECs were examined here on the basis of maximum methane production and current density relative to the inoculum community structure. We used anaerobic digester (AD) sludge domin...

Microbial Community Analysis Using MiSeq Sequencing and Pathway of Methane Production in Tehran WWTP: A Full-Scale Anaerobic Digester

Introduction: One of biological wastewater treatment methods that utilizes to both digesting waste activated sludge and methane production is anaerobic digestion (AD). It is believed to be most effective solution in terms of energy crisis and environmental pollution issues. Materials and Methods: In this study the sludge was digested anaerobically sampled from a full-scale WWTP, located at sou...
