Microbial community degradation of widely used quaternary ammonium disinfectants.
Benzalkonium chlorides (BACs) are disinfectants widely used in a variety of clinical and environmental settings to prevent microbial infections, and they are frequently detected in nontarget environments, such as aquatic and engineered biological systems, even at toxic levels. Therefore, microbial degradation of BACs has important ramifications for alleviating disinfectant toxicity in nontarget...
متن کاملPotential Impact of the Resistance to Quaternary Ammonium Disinfectants on the Persistence of Listeria monocytogenes in Food Processing Environments
The persistence of certain strains of Listeria monocytogenes, even after the food processing environment has been cleaned and disinfected, suggests that this may be related to phenomena that reduce the concentration of the disinfectants to subinhibitory levels. This includes (i) the existence of environmental niches or reservoirs that are difficult for disinfectants to reach, (ii) microorganism...
متن کاملDecreased activity of commercially available disinfectants containing quaternary ammonium compounds when exposed to cotton towels.
BACKGROUND Health care-associated infections (HAIs) are a significant problem in hospitals, and environmental surfaces have been implicated as a source of HAIs in the hospital environment. Furthermore, Gram-negative and Gram-positive bacteria can persist on dry environmental surfaces for as long as several months. Poorly cleaned surfaces may serve as vehicles for microbes, which may then be tra...
متن کاملQuaternary Ammonium Bacterial Cellulose for Adsorption of Proteins
Bacterial cellulose (BC) has attracted attention for preparing advanced materials due to its microfibrous structure. In this study, quaternary ammonium bacterial cellulose (QABC) as well as quaternary ammonium plant cellulose (QAPC) as adsorbents for proteins have been prepared. Introduction of the quaternary ammonium group was conducted under different conditions to determine the best conditio...
متن کاملSome Problems Involved in the Use of Quaternary Ammonium Compounds as Fabric Disinfectants.
The current awareness of problems concerned with drug resistant strains of Staphylococcus and other bacteria includes an interest in the role of bedding, nightclothing, and other garments as means of transmission of these bacteria. Duguid and Wallace (1948), Ridenour (1950), Church and Loosli (1953), Blowers and Wallace (1955), and Ravenholt and La Veck (1956) are among those who have reported ...
