The use of antimicrobial compounds in textiles has grown dramatically over the last decades. The potential application field is wide. It ranges from industrial textiles exposed to weather such as awnings, screens and tents; upholstery used in large public areas such as hospitals, hotels and stations; fabrics for transports; protective clothing and personal protective equipment; bed sheets and b...

In this study, we combined chlorophyll a fluorescence (ChlaF) measurements, using pulse-amplitude-modulate (PAM) equipment, with scanning electron microscopy in backscattered electron mode (SEM-BSE) and transmission electron microscopy (TEM) images to evaluate the actions of Koretrel at lower concentrations on Verrucaria nigrescens colonising a dolostone. ChlaF measurements are good indicators ...

PURPOSE To determine whether agents which are purportedly capable of inducing encystment of Acanthamoeba can recapitulate the signal when tested in differing formulations. METHODS In accordance with the International Standard ISO 19045, Acanthamoeba castellanii ATCC 50370 trophozoites were cultured in antibiotic-free axenic medium, treated with test solutions, and encystment rates plus viabil...

Abstract Objectives Develop a methodology for the fabrication of antimicrobial polypropylene (PP) surfaces with (i) leachable copper (II) chloride dihydrate (CuCl2·2H2O) and (ii) non-leachable magnesium hydroxide (Mg (OH)2) biocides. Methods results Two methodologies are used to develop PP surfaces. One method involves melt blending subsequent injection moulding, where biocide additives were co...

Currently little is known of newer pesticide classes and their occurrence persistence in recreational lakes. Therefore, the objectives this study were to (1) assess average concentrations loadings entering lakes three mixed land use watersheds throughout growing season, (2) evaluate longitudinally within lakes, (3) perform an ecotoxicity assessment. Six sampling campaigns conducted at from Apri...

Ce travail porte sur la contamination en biocides des eaux urbaines et milieux aquatiques superficiels soumis à une forte pression urbaine afin d’évaluer contribution rejets urbains de proposer solutions réduction efficaces, globales concertées. Dans ce but, usées brutes traitées station d’épuration, déversoirs d’orage ainsi que surface amont aval l’agglomération parisienne ont été échantillonn...

Dissemination of microbial resistance to biocides, including disinfectants, is one the acute problem, which poses biological and economic threats all countries in world. Understanding mechanisms disinfectants a necessary scientific basis for searching ways overcome it. Despite wide use developing bacterial them has been less studied than antibiotics. This review presents data on main molecular ...
