Effect of cycle digestion time and solid-liquid separation on digestate recirculated one-stage dry anaerobic digestion: Use of intact polar lipid analysis for microbes monitoring to enhance process evaluation
Use intact lipid analysis as a routine measure to monitor the active microbes. Discard the digestate liquid to control the accumulation of potential inhibitors. Optimize the solid retention time of the dry anaerobic digestion process. Identify the possible factors affecting the process performance.
