Definitions

  • the first class of agents is characterized by controlled release of active agents.
  • Iodine is the most common example.
  • the iodine is complexed onto a polymer matrix.
  • Typical polymers that are capable of trapping iodine while retaining the antimicrobial activity of the iodine are polyamines; some exemplary polymers are based on aminomethyl styrene, poly(ethylene imine), polyvinyl amine), poly(allyl amine), polyvinyl pyridine) and, polyvinyl pyrrolidone).
  • some polysaccharides which possess high affinity to iodine, such as amylose are suitable.
  • alkylbromides including bromobutane, bromohexane, bromooctane, bromodecane and bromohexadecane.
  • Compounds based on alkylation with longer alkylbromides such as bromodecane and bromohexadecane were purified by precipitation in methanol; with yield of 90% w/w.
  • the degree of alkylation with bromoalkanes was determined by microanalysis and found to be 80%.
  • Streptococcus mutants (ATCC#27351 ) were used in the study. Bacteria were cultured overnight in 5 ml of brain-heart infusion broth (BHI) (Difco, Detroit, Ml., USA), at 37 Q C. To avoid large bacterial aggregates or long streptococcal chains, the top 4ml of the undisturbed bacterial culture were transferred into a new test tube and centrifuged for 10 min at 3175xg. Supernatant was discarded and the bacteria were resuspended in 5ml phosphate buffered saline (PBS) (Sigma, St. Louis, MO., USA) and vortexed gently for 10 sec.
  • PBS phosphate buffered saline

Abstract

L'invention concerne un système de désinfection et de désintoxication d'eau faisant intervenir une unité filtrante équipée d'une couche d'une matrice résineuse qui présente des propriétés biocides et d'accumulation de contaminants. Le système de l'invention permet également d'empêcher les composants de la matrice résineuse d'être libérés dans l'eau désinfectée.
