| Περίληψη: | Sanitization is a critical foundation for the safe treatment of animal manure. High-temperature anaerobic digestion (AD) is often recommended for pathogen inactivation. However, heat stress may induce microorganisms into a viable-but-non-culturable (VBNC) state rather than truly inactivating them. This study therefore investigated the fate of Escherichia coli, Salmonella, and Enterococcus in pig manure during biothermal hydrolysis-enhanced AD (55 °C followed by 37 °C) and compared it with single-phase mesophilic AD (37 °C). In the two-phase process, culturable E. coli and Salmonella were reduced to below the detection limit (< 1 CFU/g fresh matter) at 55 °C, while Enterococcus achieved a > 5 log (Copyright © 2026 Elsevier B.V.
