Detailed explanation-1: -Anaerobic digestion is a process through which bacteria break down organic matter-such as animal manure, wastewater biosolids, and food wastes-in the absence of oxygen.
Detailed explanation-2: -Thermophilic anaerobic digestion showed higher organic matter degradation (especially fiber), higher pH and higher methane (CH4) yield, as well as better percentage of ultimate CH4 yield retrieved and lower residual CH4 emission, when compared with mesophilic conditions.
Detailed explanation-3: -Thermophilic digestion Thermophilic organisms grow optimally in a temperature range of 50°C to 60°C (122°F to 140°F).
Detailed explanation-4: -Thermophilic digestion has many advantages such as higher metabolic rate and higher consequent specific growth rate compared with mesophilic digestion, although the thermophilic bacteria death rate is higher (Duran and Speece, 1997).
