Metabolic pathways for biotransformation of benzalkonium compounds in fungal- and bacteria-based biofilm reactors

Journal of Hazardous Materials
Benzalkonium compounds (BACs) are quaternary ammonium biocides widely used in healthcare and industrial animal production, resulting in high concentrations in manure and wastewater. While BAC biodegradation has been demonstrated in wastewater and soil, little is known about the relevant biodegradation pathways in multi-species biofilm systems.

Benzalkonium chloride (BAC) and dimethyldioctadecyl-ammonium bromide (DDAB), two common quaternary ammonium compounds, cause genotoxic effects in mammalian and plant cells at environmentally relevant concentrations [PDF]

Mutagenesis, 2007
Quaternary ammonium compounds (QACs) are cationic surfactants that are widely used as disinfectants. In the present study, we tested two important representatives, namely, benzalkonium chloride (BAC) and dimethyldioctadecyl-ammonium bromide (DDAB) in four genotoxicity tests, namely, in the Salmonella/microsome assay with strains TA 98, TA 100 and TA ...
