Available in PDF, EPUB and Kindle. Book excerpt: Study of the phenomena of bacterial adhesion to surfaces has accelerated considerably over the past 10 to 15 years. During this period, microbiologists have become increasingly aware that attachment to a substratum influences considerably the activities and structures of microbial cells. Moreover, in many cases attached communities of cells have important effects on their substratum and the surrounding environment. Such phenomena are now known to be important in plant and animal hosts, water and soil ecosystems, and man-made structures and industrial processes. Much work on microbial adhesion in the early 1970s was descriptive. Those studies were important for detecting and describing the phenomena of bacterial adhesion to substrata in various environments; the findings have been presented in numerous recently published, excellent books and reviews. In some studies, attempts were made to elucidate some funda mental principles controlling adhesion processes in different environments containing a variety of microorganisms. Common threads have been observed occasionally in different studies. Taken as a whole, however, the information has revealed that many disparate factors are involved in adhesion processes. Whether a particular microorganism can adhere to a certain substratum depends on the properties of the microbial strain itself and on charac teristics of the substratum and of the environment.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Understanding the adhesion of bio-molecules and microorganisms to abiotic surfaces is an important consideration in food industry. The formation of these biofilms can have deleterious effects leading to contamination of food or materials coming into contact with them, causing spoilage &/or safety concerns. Among the biomolecules proteins are known to adhere to the surface very rapidly, followed by other biomolecules and microorganisms. In this study the two abiotic model surfaces, were conditioned with proteins [bovine serum albumin, sodium caseinate], microbial growth media [tryptic soya broth] and milk [whole milk, skim milk] under static and dynamic flow processing conditions. The extent of protein adsorbed to surfaces was quantified using the micro BCA protein assay. The food contact surfaces conditioned or without conditioning, were characterized using contact angle measurements to obtain various surfaces thermodynamic properties. The conditioning solutions were also characterized by dynamic light scattering and zeta potential measurements. The total free energy of interaction was calculated using the thermodynamic and the extended XDLVO models, and the adhesive potential of the biofilms was evaluated. The effect of preconditioning on the adhesion of bacteria to mica and polystyrene were studied. In addition the distribution of conditioning solutions and bacteria on the surface was evaluated using atomic force microscopy. The results under static conditions showed that the amount of proteins adsorbed on mica was much higher than polystyrene surfaces which may be because mica is more hydrophilic and polystyrene more hydrophobic. Sodium caseinate had the highest adsorption on both mica and polystyrene when compared to other conditioning solutions. The thermodynamic properties of conditioned surfaces showed that they favored electron-donating or Lewis base properties which are typical for proteins in hydrated states. DLS and Zeta potential results indicated that proteins were in aggregated states in solutions and had a negative surface charge. Preconditioning of mica and polystyrene surfaces altered their surface thermodynamic properties, especially, the electron donor and acceptor components of the surface free energy. This had a significant impact on the resulting hydrophobicity of the preconditioned surfaces as compared to the surfaces which were not conditioned. The computed free energy of interaction using the two models indicated the adhesion potential of conditioning solutions (in most cases) on both surfaces, but failed to accurately predict the extent of protein adsorption on surfaces. Under laminar flow conditions the amount of protein adsorbed onto mica and polystyrene surface was approximately two times higher than those obtained under static conditions. The DLS measurements of conditioning solutions showed that particle sizes of the conditioning solutions were more polydisperse than under static conditions. Dynamic flow condition also altered the surface thermodynamic properties of mica and polystyrene as observed with static conditions. The AFM analysis of both static and flow conditioned surfaces revealed that the conditioning film formed was not a continuous film but a heterogeneous deposit and attached in the form of aggregates. The adhesion of Listeria innocua to mica and polystyrene surfaces that were preconditioned with BSA, TSB and CAS under laminar flow showed lower adhesion values in comparison with those under static settings. However, with whole milk and skim milk, higher adhesion values of L. innocua were observed under flow conditions as compared with static conditions indicating bio-film source dependent variations. It was also observed that L. innocua cell adhesion on mica and polystyrene surfaces preconditioned with CAS WML and SML under static conditions were lower than Listeria monocytogenes under similar conditions, indicating strain dependent variations." --

Available in PDF, EPUB and Kindle. Book excerpt: The general objective of this project was to examine one component of the primary biofilm, protein, which has been hypothesized to be a major component of both dissolved and adsorbed organic pools in seawater. In previous work we found that surface energy was important in determining adsorption of protein to surfaces in seawater and degradation rates by bacteria and bacterial growth. In the last phase of this work, we examined the chemical nature of actual protein in seawater using HPLC techniques which we developed, standard chemical assays, and bioassays. We showed that protein in seawater is not the same chemically as cellular protein. Bacteria appear to treat nearly all seawater protein as if it were glycolated and degrade it at much lower rates than unmodified, fresh protein. Other experiments showed that cellular protein introduced into seawater is quickly modified by abiotic reactions and becomes less easily hydrolyzed by bacterial proteases within hours. The abiotic reactions appear to include adsorption to small colloids. These results begin to explain the growth dynamics of microorganisms on surfaces and the origin of refractory organic matter which is highly abundant in seawater ...

Book excerpt: Municipal and industrial wastewaters contain a wide spectrum of pollutants. Their effective removal presents a challenge for water treatment technology. Biosorption of nutrients and pollutants has been used in sewage treatment since the discovery of the activated sludge process. It is a passive uptake process by which pollutants are adsorbed on the surface of cell walls and/or dissolved in structures of microorganism cells that are present in sludge. Sorbed pollutants remain in the sludge and can be potentially released back into the environment depending on their condition and the reversibility of the pollutant-sludge interaction. An overview of typical biosorption applications for the removal of nutrients, organic pollutants, and metals in wastewater treatment is provided in different areas of their use for the protection of aquatic ecosystems and human health. This book will be of interest to operators of wastewater treatment plants and sludge treatment and disposal facilities as well as to researchers and university students in the field of environmental engineering.

Tosteson and published by . This book was released on 1988 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diversity and variability of macromolecular components that mediate initial microbial attachment to surfaces in ambient seawater is being determined employing immunological techniques. Antisera against microbial adhesion enhancing (MAE) macro-molecules have been raised in chickens and the immunoglobin-G (IgG) fraction utilized for isolation of crude MAE macromolecules from samples of cell free coastal seawater and marine microbial culture media by immunoaffinity chromatography. The objective of the present study is to produce monoclonal antibodies (MAbs) against AE macro-molecules, and use these to chromatographically isolate and purify individual MAE macromolecules from mixtures of such components. Variability and diversity of MAE macromolecules produced by biofouling microorganisms, those found in ambient seawater and on biofouled surfaces will be assessed employing a spectrum of AE MAbs. The specificity of the interactions of the various MAE macromolecules with glass and metallic surfaces will be assessed. Alternations in the physical characteristics of the test surfaces and changes in their susceptibility to microbial biofouling will be correlated with these interactions. (kt).
