Available in PDF, EPUB and Kindle. Book excerpt: Cytochemical analyses of the four imperfect fungi, Cylindrocephalum sp., Curvularia lunata, Aspergillus oryzae, and Gliocladium deliquescens showed that the resistant material in their cell walls is chitin. All efforts to identify cellulose produced negative results. Solutions of chitinase-containing Worthington Lysozyme (Muramidase) in concentrations of 0.5mg./ml. brought about dissolution of the cell walls and dispersion of the cell contents. Enzymatic hydrolysis represents the most suitable method now available for the conversion of fungal cell wall chitin to digestible end products with the simultaneous release of nutrient substances in the protoplasm. Specific studies have continued on protoplasmic phenomena within the cells of fungi examined, especially Heterocephalum aurantiacum Plastid-like structures in the protoplasts are the cell organs which produce chitin. Chitin-forming plastids increase in number by direct division and the quantities of chitin at their surfaces, in a given cell, may be equal to or greater than the amount of chitin in the cell wall. This information necessitates the inclusion of chitin located in the protoplasts, as well as that in the cell walls, in any considerations of fungal tissues as food for astronauts in extended explorations of space.

Available in PDF, EPUB and Kindle. Book excerpt: As a part of the research program designed to solve the nutritional problems of astronauts during extended explorations of space, cell wall substances of four fungi, Heterocephalum aurantiacum, Spicaria sp., Cladosporium sp. and Linderina pennispora have been identified and localized by standard cytochemical methods. Chitin is the resistant cell wall material in the component cells of all of these fungi and results of efforts to identify cellulose in the same cell walls have been negative. Excretions which accumulate on the surfaces of the aerial corticating hyphae of H. aurantiacum are composed primarily of calcium salts and an unidentified colloidal material, yellow-orange in color and having many characteristics in common with the so-called "fungal gamboge." Reactions of the previously untreated chitinous cell walls to the enzyme, chitinase, are positive. Enzymatic hydrolysis represents the most suitable method now available for the conversion of chitin to N-acetylglucosamine with the accompanying breakdown of the cell wall and concurrent release of nutritive substances in the protoplast. X-ray diffraction patterns of chitin have been obtained from purified cell wall samples. Measurements of these same samples, at successive stages of removal of non-chitinous materials, show a gradual increase in refractive index values. Progress has been made in the adaptation of interference microscopy to the study of chitinous cell walls during the process of hydrolysis with chitinase.
Download or read book Biochemistry of Cell Walls and Membranes in Fungi written by Paul J. Kuhn and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the many advances made during the last decade in various aspects of fungal biochemistry, there have been very few volumes devoted to the sub ject in recent years. This lack is all the more surprising in view of the increas ing use of fungi in gene manipulation studies and in biotechnological ap plications, and of the current interest in the biorational discovery of novel agents for the control of fungal pathogens of plants and humans. We hope that this book goes some way to rectifying this situation by providing an up to-date account of selected developments in two important areas, namely cell walls and membranes. Topics included in the book concern both yeasts and filamentous fungi. Although the main emphasis is on biogenesis, functional aspects are also discussed, e.g. the role of glycoproteins in recognition of sterols in mem branes and of calcium in regulation. Several contributions describe in terference with the 'normal' biochemistry of cell walls and membranes with a view to increasing fundamental knowledge, but also highly relevant to the design of new fungicides and antimycotics. The steadily increasing impact of molecular biology on the study of fungal biochemistry is highlighted throughout.

Available in PDF, EPUB and Kindle. Book excerpt: Recent findings on the role of the cell wall of pathogenetic fungi in the pathogenic processes of both vertebrates and invertebrates are presented. The fungal cell wall not only gives shape to the fungus, but it is a dynamic structure allowing fungal growth and survival of fungi in both friendly and adverse environments. It acts as a living sieve controlling the entry of nutrients and the secretion of metabolic products. In terms of fungal pathogenesis, the fungal wall may be responsible for eliciting the defense response of their respective invertebrate or vertebrate hosts or conversely it may provide protection against the host defense system during the pathogenic process.

Available in PDF, EPUB and Kindle. Book excerpt: Three years ago when Professor Garry Cole visited our Mycology unit at the Pasteur Institute we discussed the possibility of organizing a small International Symposium on "Isolation, Purification and Detection of Fungal Antigens" limited to 8 American/Canadian scientists and to 8 French participants. The location chosen was the Pasteur Institute because of the historical and current importance of the Institute as a Center for Research in Immunology and Medical Mycology. The interest demonstrated by all medical mycolo gists we contacted led us to expand the small original meeting to an international symposium in which all aspects of antigens of pathogenic and allergenic fungi and actinomycetes related to man, animals, and even plants would be discussed. Our wish was also to hold this Symposium in the same week as the Anniversary meeting of the French Society of Medical Mycology which was founded at the Pasteur Institute 30 years ago with my colleagues Gabriel Segretain and Francois Mariat.
Download or read book Current Research Topics in Applied Microbiology and Microbial Biotechnology written by Antonio Mendez-Vilas and published by World Scientific. This book was released on 2009 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a compilation of papers presented at the II International Conference on Environmental, Industrial and Applied Microbiology (BioMicroWorld2007) held in Seville, Spain on 28 November OCo 1 December 2007, where over 550 researchers from about 60 countries attended and presented their cutting-edge research. The main goals of this book are to: (1) identify new approaches and research opportunities in applied microbiology, presenting works that link microbiology with research areas usually related to other scientific and engineering disciplines; and (2) communicate current research priorities and progress in the field. The contents of this book mirror this focus. Microbiologists interested in environmental, industrial and applied microbiology and, in general, scientists whose research fields are related to applied microbiology can find an overview of the current state of the art in the topic. In addition to the more general topic, some chapters are devoted to specific branches of microbiology research, such as bioremediation; biosurfactants; microbial factories; biotechnologically relevant enzymes and proteins; microbial physiology, metabolism and gene expression; and future bioindustries."
