Question

A little breath of fresh air into an anaerobic system: how microaeration facilitates anaerobic digestion process

Answer 1

• Oxidation-reduction potential is a reliable approach to precisely control micro aeration in anaerobic digestion (AD) process.

• Anaerobes survive under a micro-aerobic condition with various anti-oxidation mechanisms.

• Micro aeration promotes microbial activity, diversity, and syn-trophy in AD processes.

• Anaerobic processes under micro aerobic conditions need in depth evaluation at molecular level
