Anaerobic Digestion & Microaeration
Research
Our group investigates the complex microbial consortia involved in anaerobic digestion and develops strategies to maximize biogas (methane) yields from diverse organic waste streams. We combine advanced microbiome analysis with process engineering to understand inhibition mechanisms and develop novel reactor configurations.
A major focus is integrating micro-aeration with anaerobic digestion — selectively introducing small amounts of oxygen to improve sulfide oxidation, enhance volatile fatty acid utilization, and boost methane yields without disrupting methanogenesis.
- High-solids anaerobic co-digestion of food waste and biosolids
- Effect of trace metals and inhibitors on methanogenesis
- Temperature-phased and psychrophilic anaerobic digestion
- Bioaugmentation with syntrophic microorganisms
- Digestate valorization and nutrient recovery
- Micro-aeration integration for H₂S removal and methane enhancement
- Household digester technology and digestate utilization in Cambodia
