This work studied the combined effects of antibiotics (ABs) frequently found in cattle manure on anaerobic digestion (AD) process. AB persistence and antibiotic resistance genes (ARGs) occurrence were evaluated. For this purpose, a batch experiments was set up using mixture digestate simulating substrate composition inside full-scale reactor (ratio 1:35, respectively). Enrofloxacin added alone (ENR: 7.5 mg kg-1), or mixed with equal amounts sulfamethoxazole (SMX) ciprofloxacin (CIP) at low (Mix_L: 2.5mg kg-1 each AB) high (Mix_H: concentrations. ABs slightly influenced CH4 production, which continued for more than six months values between 5939±93 6464±94 mL L-1. At day 51, SMX resulted removed, whereas enrofloxacin CIP partially degraded (<50%). ARGs also strongly reduced 51. Microbial community structure, including fungi, neglected component AD microbioma, analysed.

Anaerobic digestion (AD) is a waste-to-energy strategy that leverages natural microbiological processes. It increasingly used in farms to treat manure, resulting biogas for energy production and digestate as fertiliser. However, animal manure often contains antibiotic (AB) residues, raising concerns about their impact on AD efficiency potential spread through use. This multidisciplinary study evaluated the effects of an AB mixture (enrofloxacin, ciprofloxacin sulfamethoxazole) CH4 production, microbial community (Fungi, Bacteria Archaea) dynamics resistance gene (ARG) presence. The experiment cattle manure/digestate ratio 1:35, typical real digesters, with concentrations set at low (2.5 mg kg−1 each) high (7.5 levels. ABs affected cumulative (ranging from 5939 6464 mL) only highest concentration. After 51 days, sulfamethoxazole reached residual levels, while enrofloxacin were partially degraded (<50%), but ARGs significantly reduced. community, particularly prokaryotes, exhibited resilience, maintaining efficient production. Overall findings strongly suggest effective treatment producing good fertiliser, also reducing ARG content well mitigating emissions into atmosphere.
