Available in PDF, EPUB and Kindle. Book excerpt: Analytical Microbiology focuses on the processes, methodologies, developments, and approaches involved in analytical microbiology, including microbiological, antibiotic, and amino acid assays and dilution methods. The selection first offers information on the theory of antibiotic inhibition zones, microbiological assay using large plate methods, and dilution methods of antibiotic assays. Discussions focus on serial dilution assay, requirements for accurate assay, microbiological assay of riboflavin, laws of adsorption and partition, mechanisms of antibiotic action, and biological considerations affecting the use of statistical methods. The text then ponders on the elements of photometric assaying and automation of microbiological assays. The manuscript elaborates on antibiotic substances, vitamins, and amino acids. Topics include assay organisms, validity, specificity, reliability, and calculation of results of amino acid assays, bacitracin, chloramphenicol, dihydrostreptomycin, erythromycin, neomycin, and streptomycin. The selection is a dependable reference for researchers interested in analytical microbiology.

Available in PDF, EPUB and Kindle. Book excerpt: Theory and Application of Microbiological Assay first presents an overview of microbiological assay, including general principles, basic techniques, capabilities, and limitations. This book also explains when to use a certain microbiological assay for specific analysis, citing examples to further clarify the matter. Some chapters discuss the test organisms and solutions, wherein test solutions are the final dilutions at a series of two or more concentrations that have been prepared from reference standard and unknown for application to the test system. Other chapters explore the various aspects of agar diffusion assays, tube assays, and diffusion assays. The book further looks into the quality control procedures, assay design and evaluation, and assay replication. This book will serve as an introduction to newcomers to the field and as a reference source for established workers in microbiological assay.
Download or read book Microbiological Assay for Pharmaceutical Analysis written by William Hewitt and published by CRC Press. This book was released on 2003-12-15 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: A user-friendly guide for the evaluation of microbiological assays, this book provides a lucid explanation of the sources of error in microbiological assay and helps analysts choose efficient assay designs that will minimize those sources of error. The author discusses microbiological assay as a branch of pharmaceutical analysis and distinguishes it from biological assay in general. He draws attention to the microbiological aspects that may not be so obvious to the chemical analyst and to the analytical aspects that may not be so obvious to the microbiologist. The book expands on the guidance given in pharmacopoeias and helps readers choose the assay design most appropriate for the purpose of their assay.

Available in PDF, EPUB and Kindle. Book excerpt: This Symposium on Modern Methods of Food Analysis was the sev enth in a series of basic symposia, begun in 1976, on topics of major importance to food scientists and food technologists. The Symposium, sponsored jointly by the Institute of Food Technologists and the In ternational Union of Food Science and Technology, was held June 17 and 18, 1983, in New Orleans immediately prior to the 43rd annual 1FT meeting. Like the other six basic symposia, the program brought together outstanding speakers, from biochemistry, chemistry, food science, microbiology and nutrition, who are at the cutting edge of their specialty, and provided a setting where they could interact with each other and with the participants. The Symposium and this book are dedicated to the memory of George F. Stewart (1908-1982) who made so many important contributions to the field of food science, including that of food analysis. Bernard S. Schweigert has documented George F. Stewart's contributions in the Dedication of this book.

Download or read book Indicators for Waterborne Pathogens written by National Research Council and published by National Academies Press. This book was released on 2004-06-19 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent and forecasted advances in microbiology, molecular biology, and analytical chemistry have made it timely to reassess the current paradigm of relying predominantly or exclusively on traditional bacterial indicators for all types of waterborne pathogens. Nonetheless, indicator approaches will still be required for the foreseeable future because it is not practical or feasible to monitor for the complete spectrum of microorganisms that may occur in water, and many known pathogens are difficult to detect directly and reliably in water samples. This comprehensive report recommends the development and use of a "tool box" approach by the U.S Environmental Protection Agency and others for assessing microbial water quality in which available indicator organisms (and/or pathogens in some cases) and detection method(s) are matched to the requirements of a particular application. The report further recommends the use of a phased, three-level monitoring framework to support the selection of indicators and indicator approaches.Â
