Analytical Microbiology


Book Description

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.

Analytical Microbiology Methods


Book Description

The First International Symposium on the Interface between Analytical Chemistry and Microbiology: Applications of Chromatography and Mass Spectrometry was held June 1987 at the University of South Carolina, Columbia, SC, U.S.A. The purpose of the "Interface" meeting was to forge connections between analytical chemists and microbiologists that are using chromatography and mass spectrometry to solve common problems. The goals were admirably fulfilled. Nearly a hundred participants from seven European countries, Japan, and the United States participated in hearing twenty-three plenary talks and thirty-six submitted papers and posters. The papers and discussions displayed the breadth and depth of current research applications and revealed future directions. This book "Analytical Microbiology Methods: Chromatography and Mass Spectrometry" is loosely based on some of the presentations and discussions at the meeting. Each chapter describes specific methodology and applications in the context of the relevant scientific background. The present book continues the theme of an earlier book, "Gas Chromatography/Mass Spectrometry Applications in Microbiology", edited by G. Odham, L. Larsson, and P-A. Mardh, published by Plenum Press in 1984.

Analytical Microbiology, Volume II is a six-chapter work that covers the significant changes and improvements made in the theory and practice of analytical microbiology. The first chapter is devoted to the theoretical aspects of assaying of specific compounds. These topics are followed by discussions of the theoretical and practical aspects of diffusions assays, as well as the theoretical developments of photometric methods of assay, including their improvement resulting from automation. A chapter explores the assay methods for various antibiotic groups. Another chapter discusses the advances in assay technology and analytically important interrelations among the folic acid complex. The last chapter describes a simple diffusion method designed for the assay of certain amino acids in a wide variety of samples. This book will prove useful to analytical microbiologists.

Microbiological Analysis of Red Meat, Poultry and Eggs


Book Description

Red meat, poultry and eggs are, or have been, major global causes of foodborne disease in humans and are also prone to microbiological growth and spoilage. Consequently, monitoring the safety and quality of these products remains a primary concern. Microbiological analysis is an established tool in controlling the safety and quality of foods. Recent advances in preventative and risk-based approaches to food safety control have reinforced the role of microbiological testing of foods in food safety management.In a series of chapters written by international experts, the key aspects of microbiological analysis, such as sampling methods, use of faecal indicators, current approaches to testing of foods, detection and enumeration of pathogens and microbial identification techniques, are described and discussed. Attention is also given to the validation of analytical methods and Quality Assurance in the laboratory. Because of their present importance to the food industry, additional chapters on current and developing legislation in the European Union and the significance of Escherichia coli 0157 and other VTEC are included.Written by a team of international experts, Microbiological analysis of red meat, poultry and eggs is certain to become a standard reference in the important area of food microbiology. - Reviews key issues in food microbiology - Discusses key aspects of microbiological analysis such as sampling methods, detection and enumeration of pathogens - Includes chapters on the validation on analytical methods and quality assurance in the laboratory




Microbiological Analysis of Food and Water


Book Description

With the help of leading Quality Assurance (QA) and Quality Control (QC) microbiology specialists in Europe, a complete set of guidelines on how to start and implement a quality system in a microbiological laboratory has been prepared, supported by the European Commission through the Measurement and Testing Programme. The working group included food and water microbiologists from various testing laboratories, universities and industry, as well as statisticians and QA and QC specialists in chemistry.This book contains the outcome of their work. It has been written with the express objective of using simple but accurate wording so as to be accessible to all microbiology laboratory staff. To facilitate reading, the more specialized items, in particular some statistical treatments, have been added as an annex to the book. All QA and QC tools mentioned within these guidelines have been developed and applied by the authors in their own laboratories. All aspects dealing with reference materials and interlaboratory studies have been taken in a large part from the projects conducted within the BCR and Measurement and Testing Programmes of the European Commission.With so many different quality control procedures, their introduction in a laboratory would appear to be a formidable task. The authors recognize that each laboratory manager will choose the most appropriate procedures, depending on the type and size of the laboratory in question. Accreditation bodies will not expect the introduction of all measures, only those that are appropriate for a particular laboratory.Features of this book:• Gives all quality assurance and control measures to be taken, from sampling to expression of results• Provides practical aspects of quality control to be applied both for the analyst and top management• Describes the use of reference materials for statistical control of methods and use of certified reference materials (including statistical tools).
