The impact of weak magnetic field (WMF) on anaerobic digestion (AD) performance of waste activated sludge (WAS) and underlying mechanism were investigated. Results showed that WMF significantly stimulated the methane yield by 12.9∼25.1% with 15 and 30 mT WMF addition, but high WMF (60 mT) attenuated the positive effect...
In what ways did WMF affect the population and activity of anaerobic microbes, particularly acetoclastic and hydrogenotrophic methanogens?
The abstract states that WMF enriched the anaerobic microbes, especially the acetoclastic and hydrogenotrophic methanogens. Additionally, WMF facilitated the metabolic pathways of key enzymes for methanogenesis.
