Abstract
Fluorescent staining techniques were used to study the anti-microbial properties of aqueous suspensions of a novel, water insoluble amino functionalised polymer on three micro-organisms Pseudomonas fluorescens, Staphylococcus epidermidis and Saccharomyses cerevisiae. The mechanism of action was similar for each organism in that, after various contact times with the polymer, a progressive change in individual cell physiological state was measured using multi-parameter flow cytometry. The microbiocidal activity of this polymer may be similar to that of substances referred to as polycationic, amphipathic compounds (peptides, peptide derivatives and other polyamines).
