Anaerobic digestion (AD) is a well-established technology for the sustainable conversion of agricultural organic by-products and waste into bioenergy. Temperature crucial optimizing methane production through inocula preservation reactor start-up in AD. The induced by temperature has rarely been assessed from an engineering perspective. There also limited exploration influence high-to-moderate transition on initiation This study employed continuous mesophilic AD reactors with potential applications to conduct revival tests. These tests evaluated activity sludge stored at different temperatures investigated impact high-temperature Additionally, we elucidated correlation between these assessments microbial diversity as well composition. results indicated that bacterial was higher inoculum 35 °C compared 15 °C, ensuring stable operation richness bacteria archaea remained during high temperatures. conducive enhancing methanogenic initiated 55 °C. continuously operated system showed significant differences composition its inoculum. Increased abundance Coriobacteriaceae Prevotellaceae led propionate butyrate accumulation, respectively, reducing operational capacity. Methanogenic were less diverse low-temperature preserved medium temperature. Streptococcaceae temperarure could promote stability. Hydrogenotrophic methanogens had competitive advantage due their prior exposure initiation, possibly influenced Thermotogaceae.
