Abstract Micro-aeration was shown to improve anaerobic digestion (AD) processes, although oxygen is known inhibit obligate anaerobes, such as syntrophic communities of bacteria and methanogens. The effect micro-aeration on the activity microbial interaction in communities, well potential establishment synergetic relationships with facultative (FAB) or aerobic (AB), investigated. Anaerobic sludge incubated ethanol increasing concentrations (0–5% headspace). Assays acetate H 2 /CO (direct...
Abstract Waste glycerol is produced in excess by several industries, such as during biodiesel production. In this work, the metabolic versatility of anaerobic sludge was explored towards waste valorization. By applying different environmental (methanogenic and sulfate-reducing) conditions, three distinct microbial cultures were obtained from same inoculum (anaerobic granular sludge), with high specialization, within phyla ( Thermodesulfobacteriota , Euryarchaeota Pseudomonadota ). The are...
Summary Glycerol‐rich waste streams produced by the biodiesel, bioethanol and oleochemical industries can be treated valorized anaerobic microbial communities to produce methane. As current knowledge of microorganisms involved in thermophilic glycerol conversion methane is scarce, glycerol‐degrading methanogenic were enriched. A co‐culture Thermoanaerobacter Methanothermobacter species was obtained, pointing a non‐obligately syntrophic degradation. This hypothesis further studied incubating...
Trace amounts of oxygen stimulate facultative anaerobic bacteria (FAB) within bioreactors, which was shown to correlate with enhanced methane production from long-chain fatty acids. The relationship between FAB and acid-degrading syntrophic communities under micro-aerobic conditions is still unclear. In this work, two co-cultures, Syntrophomonas wolfei + Methanospirillum hungatei zehnderi Methanobacterium formicicum, were assembled incubated short, medium acids, 0-10 % O
