Because of the magnificent response to the call for papers for the 7th International Biodeterioration Symposium held at Cambridge, UK, some difficulties have been experienced in the editing of these proceedings. The numbers of papers submitted exceeded expectation and because of this it has been necessary to accommodate those not actually in the proceedings into the International Biodeterioration journal. A small number of papers were not suitable for publication and were therefore eliminated. Many authors disregarded the guidelines laid down for the length of submitted papers. However, every attempt has been made to accommodate the maximum number of contributions in the proceedings. The original selection included those which most nearly conformed to the length requirement. Even so this has meant, in many cases, cutting down the text, eliminating tables and/or illustrations and pruning the reference list. When references have been trimmed a note has been included to the effect that an extended list may be obtained from the author/senior author. Where it was not possible to carry out these procedures without seriously altering the text and the import of the paper they have been included amongst those to be published in the journal International Biodeterioration. The exceptions to the procedures outlined above are the invited review papers which have been presented in full. Happily, the authors have been conscientious in keeping to the guidelines laid down for these contributions.

Food Preservation and Biodeterioration Food Preservation and Biodeterioration Biodeterioration is the breakdown of food by agents of microbiological origin, either directly or indirectly from products of their metabolism. Preservation on the other hand is the process by which food materials are maintained in their original condition or as close to this as possible. This second edition of Food Preservation and Biodeterioration is fully updated and reorganised throughout. It discusses how the agents of food biodeterioration operate and how the commercial methods available to counteract these agents are applied to produce safe and wholesome foods. With this book, readers will discover traditional methods and major advances in preservation technology. Both microbiological and chemical pathways are analysed. This topic being important to all producers of food, the readership spans food scientists across the industry and academia, particularly those involved with safety and quality.

Fungi-induced stains on paper are one of the most challenging forms of biodeterioration to study and to prevent; this is because they involve living organisms, and the ways in which fungi respond to changes in the environment and modifications of paper are unpredictable. Yet, there is a great desire among those who encounter fungi on documents, manuscripts, or artwork to remove fungi and clean the paper. This experience in most cases is particularly challenging. What are the reasons behind this challenge? This ground-breaking book attempts to answer this question, among others, by exploring the complex interfacial forces between paper, fungi, and their pigmented secretions which result in bio-stains on paper. Black fungi, collectively referred to as Dematiaceous fungi, were used in this study as a subset of pigment-producing fungi species. The focus is on two, under-studied aspects of the fungi infestation of paper, an interface of fungal pigments and paper, and the impact of light on the production of fungi bio-stains. The results of analytical testing included in this book elucidate the synergistic interactions between the environment, biological clocks of the microorganisms, and secretion of fungal pigments to paper. The black fungal pigment formation is explored in-depth in two scenarios: one that is ‘natural’, when the bio-stains of original artworks have occurred over time by chance, and another, induced by Aspergillus niger, in bio-simulation on known papers in a controlled environment. The findings are intended to provide guidance for preservation strategies, mitigating the biodeterioration of paper, and designing conservation treatment when applicable. The surface of artworks and artifacts is of great aesthetic and artistic importance; conversely, it plays a significant role in governing fungal attachments. In this book, the paper surface is characterized in detail and in correlation with chemical and physical alterations caused by fungal pigmentation. A broad range of analytical instruments was used for surface characterization, such as surface metrology profilometers, a confocal laser scanning microscope, and environmental scanning electron microscope; chemical microanalysis was carried out using X-ray energy dispersive spectroscopy. The novel, three-dimensional characterization of pigmented fungal inclusions and their interaction with paper matrix was studied with micro-X-ray-computed micro-tomography on the synchrotron ESRF. The proposed book is the first to explore the complexity of fungal–paper interactions with the intention to assist professionals working with cultural materials, especially paper-based materials, to make informed decisions when dealing with the fungi infestation of paper.

Examines the application of scientific methods to the study and conservation of art and cultural properties. This work addresses scientific topics of broad interest, cutting across the boundaries of traditional disciplines and attracting up to 250 leadingresearchers in the field.

Biofilms -- Science and Technology covers the main topics of biofilm formation and activity, from basic science to applied aspects in engineering and medicine. The book presents a masterly discussion of microbial adhesion, the metabolism of microorganisms in biofilms, modelling of mass transfer and biological reaction within biofilms, as well as the behaviour of these microbial communities in industry (waste water treatment, heat exchanger biofouling, membranes, food processing) and in medicine (teeth, implants, prosthetic devices). Laboratory techniques and industrial monitoring methods are also presented. The book is directed at readers at the postgraduate level and is organised as a textbook, containing 11 chapters, a glossary, and a detailed subject index.
