Abstract

Graphical abstract: Highlights: Sulfachloropyridazine (SCP) did not promote bacterial diversity. SCP alter anaerobic digestion (AD) bacterial community for volatile fatty acid (VFA). Reduction of VFA increased with increasing initial SCP concentration. Initial SCP concentration had a positive correlation with VFA production. Results assessed the applicability of AD for VFA to swine manure with SCP. Abstract: This study aimed to investigate the antibiotic of sulfachloropyridazine (SCP) reduction and its effects on volatile fatty acids (VFAs) accumulation and microbial community structures during the process of anaerobic digestion (AD) producing VFA. Results showed that initial SCP concentrations have a positive correlation with reduction of SCP and accumulation of VFAs. The removal rates of SCP were 22.21%, 30.00%, 39.31% and 42.59% and the maximum production of VFAs were 3947, 6180, 6462 and 6032 mg/L for initial SCP concentrations of 25, 50, 75 and 100 mg/kg·TS, respectively. SCP only altered bacterial composition by hastening growth of specific bacterial taxa, but didn't increase bacterial α-diversity.
