Synthesis and Disinfection Effect of the Pyridine-4-aldoxime Based Salts [PDF]

open access: yesMolecules, 2015
A set of new quaternary ammonium compounds based on pyridine-4-aldoxime was synthesized, characterized with analytical data (NMR, EA, HPLC, MS) and tested for in vitro antimicrobial activity (antibacterial, antifungal) and cytotoxicity.

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]

open access: closedMutagenesis, 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 ...

The toxicity of the quaternary ammonium compound benzalkonium chloride alone and in mixtures with other anionic compounds to bacteria in test systems with Vibrio fischeri and Pseudomonas putida

open access: closedEcotoxicology and Environmental Safety, 2008
Mixtures of chemicals are present in the aquatic environment but standard testing methods assess only single compounds. One aspect of this question is the importance of the formation of ionic pairs, for example from quaternary ammonium compounds with organic anions, and the significance of the ionic pairs for bacterial toxicity in the aquatic ...

Kaolinite Sorption Isotherms of Benzalkonium and Dialkyldimethylammonium Compounds under Dilute Conditions Investigated by Direct and Passive Sampling Methods [PDF]

open access: bronze
Cationic surfactants are widely used in various applications, making their environmental behavior a critical concern. However, soil sorption studies at environmentally relevant submicromolar concentrations remain scarce. In this study, sorption isotherms of five benzalkonium compounds (BACs) and two dialkyldimethylammonium compounds on kaolinite under ...

Exploring antimicrobial interactions between metal ions and quaternary ammonium compounds toward synergistic metallo-antimicrobial formulations [PDF]

open access: yesMicrobiology Spectrum
Multi-target antimicrobial agents are considered a viable alternative to target-specific antibiotics, resistance to which emerged as a global threat. Used centuries before the discovery of conventional antibiotics, metal(loid)-based antimicrobials (MBAs),

Comparative Evaluation of the Effects of Binzalkonium Chloride, Iodine, Gluteraldehyde and Hydrogen Peroxide Disinfectants against Avian Salmonellae Focusing on Genotypic Resistance Pattern of the Salmonellae Serotypes toward Benzalkonium Chloride [PDF]

open access: yesBrazilian Journal of Poultry Science, 2020
Using disinfectants in poultry houses is a common practice to ban the zoonotic pathogens like Salmonella. A major concern in using disinfectants is the emergence of bacteria strains that resist some disinfectants.
