Amine Micropollutant Effects on Sludge Digestion and Methanogens

Six representative amine-containing micropollutants were studied for their transformation and impact on sludge anaerobic digestion. The research identified dominant transformation reactions and measured specific enzyme activity reductions and methane yield drops exceeding 88%. Siying Cai published this experimental dataset on figshare in April 2026.

Use Cases

• Model methane production yield reduction from exposure to quaternary ammonium compounds like DDBAC and DDDAC.
• Analyze shifts in microbial community composition, such as from Methanosarcina flavescens to Methanobacterium sp., linked to AMP exposure.
• Correlate acetate kinase activity inhibition percentages with specific AMP chemical structures.
• Study the prevalence of α-C hydroxylation and N-acetylation transformation products among identified reaction pathways.

Strengths

• Dataset covers 16 structurally diverse amine functionalities across six representative compounds.
• Reports specific quantitative impacts, including methane yield reductions of 88.97% and 88.19% for two compounds.

Limitations

• Dataset size is only 403.0 KB, indicating limited raw data volume.
• No column names or sample data are provided, complicating direct analysis.
• Experimental scope is limited to six selected AMP compounds.
