Temperature-Driven Responses and Contributions of Hyperthermophiles: Linking Storage and Inoculation Strategies in Municipal Sludge Composting [PDF]

Microorganisms
Conventional aerobic composting is limited by incomplete organic matter degradation, long composting times, and low product quality. Hyperthermophiles have been applied in composting, but systematic studies on their storage conditions and inoculation ...
