“…PF, a green oxidant, has been used for drinking water disinfection and for suppressing pathogenic microorganisms in soil and groundwater. 48 PF may cause pathogen inactivation via nonselective protein degradation, DNA damage, and cytoplasmic membrane decomposition. 49 Our previous research demonstrated that the PF treatment samples had thousand-fold lower total coliform and Escherichia coli counts than the UP samples.…”

The decomposition and pathogen inactivation of fecal sludge (FS) are vitally important for safely managing onsite sanitation and protecting public and environmental health. However, the microbiome and virome assemblages in FS after chemical and biological treatments remain unclear. Here, we reported the differences in the solid reduction and microbiomes of FS subjected to potassium ferrate (PF), alkali (ALK), and sodium hypochlorite (NaClO) pretreatments and anaerobic digestion (AD). The PF and NaClO pretreatments enhanced FS hydrolysis and pathogen suppression, respectively; AD suppressed Grampositive bacteria. Most of the viromes were those of bacteriophages, which were also shaped by chemical pretreatments and AD. Metatranscriptome analysis revealed distinct gene expression patterns between the PF-and ALK-pretreated FS and the subsequent AD. Differentially expressed gene profiles indicated that genes related to biological processes, molecular functions, and transcriptional regulators were upregulated in ALK-AD and PF-AD samples. These findings suggested that the effect of different treatment technologies on the viral diversity, pathogen abundance, and metabolic function of the core microbiome extends beyond FS decomposition and that the use of combined processes would provide possible alternatives for FS management in pandemic emergencies.

“…Fe(VI) is environmentally friendly for treating water without producing secondary pollution [31] . In recent years, researches on the oxidation of antibiotics by Fe(VI) have been forthcoming, including the reaction kinetics, but the knowledge of antimalarial drugs (e.g., CLQ) and products of the oxidations under natural water conditions are very limited [32] , [33] . Significantly, due to the high toxicity and biological resistance of degradation products, the removal may not necessarily obviate the antibacterial properties completely [34] , [35] .…”
