This volume in the book series New Concepts in Polymer Science deals with the damaging effects, which microorganisms such as bacteria, fungi, et cetera can have on a range of materials in machinery. The book aims to provide theoretical notions about the mechanisms of material damaging by microorganisms under operation conditions as well as to give recommendations for protection of technical articles and machinery.Adhesive interaction between microorganisms-destructors and materialsAppendix 1: The effect of various factors on damaging of polymeric materials by microorganismsAppendix 2: Kinetics of radial growth of Aspergillus colonies at different temperaturesAppendix 3: Kinetics of acids excretion in medium by mycelial micromycetes coloniesChanges in material properties induced by physical processesChanges in material properties induced by chemical processesCharacteristics and determination methods of the interaction between mircroorganisms-destructors and materialsDamages of materials of technical articles induced by microorganismsDependence of adhesion on properties of material, spores of microscopic fungi and temperature-humidity conditions of the surroundingsDependence of microbiological growth on properties of material, microorganism and temperature-humidity conditions of the environmentGeneral investigation techniqueGrowth of microorganisms-destructors on materialsInteraction between materials and microorganisms-destructorsIntroductionMaterials subject to damage and microorganisms-destructorsMaterial properties variation under the action of microorganismsMathematical modeling and prognosis of microbiological damaging of materialsMethods and facilities for protection of articles agains microbiological damagesModern ideas about biodamaging of materials and technical articles.

Investigation techniques for studying microbiological resistance of materials and efficiency of protection facilitiesTemperature and air humidity; The species composition and activity of microorganisms-destructors; Aging of polymeric materials; Pollution composition; The effect of technogenic magnetic fieldsThis monograph consists of the following topics: finding of kinetic regularities, analytical models and quantitative indices for stages material biodamaging; study of influence of properties of materials, features of microorganisms, temperature, humidity and other factors on interaction between a material and a biodestructor; and, compilation of guidelines to determine and forecast biological resistance (bioresistance) of materials, development of means and methods for their protection as well as estimates of their efficiency.This monograph will be of value and interest to researchers and engineers working in fields in which materials are subject to active microbiological aging and destruction.
