The usefulness of kinetic methods to estimate the biocidic activity of substances is presented. The procedure for a quantitative estimation of biocide efficiency, independent on their solubility in water, is discussed. It is shown, that inhibited kinetics of microscopic fungi growth on nutriments with biocides can be described by the equation of logistic function. The investigation of the relationship between aging and biodeterioration processes showed that: i) Metabolites of Aspergillus niger microscopic fungus may influence physically the material, leading to a decrease of strength. This process may proceed at short times of influence of microorganism, when concentration of organic acids is low, and their diffusion in the material is practically absent. ii) On microorganism influence on polymer, chemical reactions take place acting according to the chance law. This leads to the decrease of important use properties; formation of degradation products during the aging process, and facilitation of the microorganisms growth. |
