The complete genome sequence of the rumen methanogen Methanosarcina barkeri CM1
Methanosarcina species are the most metabolically versatile of the methanogenic Archaea and can obtain energy for growth by producing methane via the hydrogenotrophic, acetoclastic or methylotrophic pathways. Methanosarcina barkeri CM1 was isolated from the rumen of a New Zealand Friesian cow grazing a ryegrass/clover pasture, and its genome has been sequenced to provide information on the phyl...
متن کاملIncreasing of leachate quality using an integrated aerobic membrane bioreactor
The aim of this study was the increasing of leachate quality using integrated membrane bioreactor (MBR). The reactor was fed with treated leachate with overall 70-1360 mg/l chemical oxygen demand (COD). The analysis of COD, biochemical oxygen demand (BOD5), total suspended solids (TSS), and total dissolved solids (TDS) were performed in feed and filtrate, whenever the system reached steady stat...
متن کاملStudy on Anaerobic/Aerobic Membrane Bioreactor Treatment for Domestic Wastewater
A 69-day experimental study was conducted to investigate the treatment process of municipal wastewater using submerged membrane bioreactor technology. The results show that the average removal rate of COD and BOD5 were over 90%. The removal rate of NH3-N was 99% and the concentration of effluent NH3-N was below 0.5mg/L; because of the high DO value in the denitration sect, the denitrobacteria w...
متن کاملEnhanced 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...
متن کاملInhibition of methanogenesis by interaction of aluminium ion with co-factor, F-420, in Methanosarcina barkeri.
Methane emission was inhibited by aluminium ion in paddy fields. Addition of Al3+ (20 mM) to the culture medium containing cells of pure Methanosarcina barkeri, inhibited methanogenesis. Methanogenic co-factor, F-420, was isolated and purified from Methanosarcina barkeri MS. Spectrophotometric and spectrofluorometric analysis of interaction between co-factor, F-420, and Al3+ revealed that they ...
