New Biotechnology Findings from Institute for Microbiology Described

June 17, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Technology is the subject of a report. According to news reporting originating in Bonn, Germany, by NewsRx journalists, research stated, "Methanogenic archaea are essential for the production of methane in biogas plants. Here we present enzymatic test systems for the analysis of the metabolic activity of methanogens based on the heterodisulfide reductase reaction."

The news reporters obtained a quote from the research from Institute for Microbiology, "The first rapid test shows that heterodisulfide reductase can be detected in 1 g of biogas sludge after sonication and centrifugation. The resulting cell lysate used reduced methylviologen for heterodisulfide reduction, a reaction that is specifically catalyzed by methanogenic heterodisulfide reductase. In the second test cell lysate from 60 g of biogas sludge was separated by ultracentrifugation."

According to the news reporters, the research concluded: "Both, cytoplasmic membrane and cytoplasmic fractions revealed heterodisulfide reductase activity, indicating the presence of hydrogenotrophic and aceticlastic methanogens, respectively."
