This book was released on 2007 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigated genetic predictions for amino acid biosynthesis and catabolism by Lactobacillus helveticus CNRZ 32, a commercial cheese flavor adjunct that reduces bitterness and intensifies flavor notes. Conversion of amino acids into volatile and nonvolatile flavor compounds by L. helveticus and other lactic acid bacteria in cheese is thought to represent the rate-limiting step in the development of mature cheese flavor and aroma. One of the primary mechanisms for amino acid breakdown by these microbes involves the reversible action of enzymes involved in biosynthetic pathways, so our group investigated the genetics of amino acid biosynthesis in L. helveticus CNRZ 32. Most lactic acid bacteria are auxotrophic for several amino acids, and phenotypic characterization of L. helveticus CNRZ 32 has shown this bacterium requires 14 amino acids. Reconstruction of amino acid biosynthetic pathways from a draft-quality (incomplete) genome sequence for L. helveticus CNRZ 32 showed generally good agreement between gene content and phenotypic amino acid requirements. One exception involved the requirement ofCNRZ 32 for Asp (or Asn) for growth, where predictions derived from the genome sequence suggested this strain may be able to synthesize Asp from citrate. This prediction was confirmed as Asp auxotrophy in L. helveticus CNRZ 32 could be alleviated by the addition of citrate to a chemically defined medium that lacked Asp and Asn. Genome analysis also predicted that L. helveticus CNRZ 32 possessed ornithine decarboxylase activity, and would therefore catalyze the conversion of ornithine to putrescine, a volatile biogenic amine. Putrescine production in cheese would be undesirable because this compound may impart a rotting flesh flavor and can also have adverse effects on human health. Experiments to confirm ornithine decarboxylase activity in L. helveticus CNRZ 32 using a special growth medium, thin layer chromatography, high performance liquid chromatograph, or 13C nuclear magnetic resonance were unsuccessful, however, which indicated this bacterium does not contribute to putrescine production in cheese.
Download or read book Handbook of Proteolytic Enzymes Volume 1 written by Alan J. Barrett and published by Elsevier. This book was released on 2012-12-02 with total page 1182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Proteolytic Enzymes, Second Edition, Volume 1: Aspartic and Metallo Peptidases is a compilation of numerous progressive research studies on proteolytic enzymes. This edition is organized into two main sections encompassing 328 chapters. This handbook is organized around a system for the classification of peptidases, which is a hierarchical one built on the concepts of catalytic type, clan, family and peptidase. The concept of catalytic type of a peptidase depends upon the chemical nature of the groups responsible for catalysis. The recognized catalytic types are aspartic, cysteine, metallo, serine, threonine, and the unclassified enzymes, while clans and families are groups of homologous peptidases. Homology at the level of a family of peptidases is shown by statistically significant relationship in amino acid sequence to a representative member called the type example, or to another member of the family that has already been shown to be related to the type example. Each chapter discusses the history, activity, specificity, structural chemistry, preparation, and biological aspects of the enzyme. This book will prove useful to enzyme chemists and researchers.

Download or read book Lactic Acid Bacteria Genetics Metabolism and Applications written by W.N. Konings and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: In ancient times foods fermented with lactic acid bacteria already constituted an important part of the human diet. From then on, lactic acid bacteria have played an essential role in the preservation of food raw materials and have contributed to the nutritional, organoleptic and health properties of human food products and animal feed. The important function that lactic acid bacteria still have in the production of foods all over the world has resulted in a growing scientific interest in these micro-organisms by academic research groups as well as by industry. During the last 15 years, this research has been stimulated by major internationally coordinated funding efforts that have resulted in a variety of important scientific breakthroughs and have led to new applications. Written by international experts in the field, this issue of Antonie van Leeuwenhoek documents these developments with respect to genetics, metabolism and the application of lactic acid bacteria for industrial and potential medical applications. In this book the first complete genome of a lactic acid bacterium is presented. The book will serve as a reference source and also as an indispensable source of information for further development and exploration of the field.
