Global Studies of Microbial Diversity in Integrated Anaerobic Digestion and Microbial Electrolysis Cell Systems Using Cellulosic Ethanol Stillage as Feedstock
AD systems primarily involve methanogens and fermentative and acidogens that degrade organic matter into methane and carbon dioxide. In the AD-MEC integration, the microbial diversity often includes a higher abundance of hydrogenotrophic methanogens such as Methanobacterium, which are crucial for efficient methane production.
