Genetics and Biotechnology of Bacilli


Book Description

Genetics and Biotechnology of Bacilli contains the proceedings of the Second International Conference on Genetics and Biotechnology of Bacilli, held at Stanford University in Stanford, California, on July 6-8, 1983. Contributors discuss the progress that has been made concerning the genetics and biotechnology of Bacillus and focus on topics built around the themes of chromosomal organization, secretion, transcription, gene cloning, gene expression, and synthesis of sporulation-associated products. This text is organized into 33 chapters and begins with an overview of bacteriophage lambda biology, with emphasis on lambda insertion, controlled DNA rearrangements, operator-promoter function, and the evolution of extrachromosomal elements. The reader is then introduced to genetic mapping of cloned ribosomal RNA genes, gene amplification in Bacillus subtilis, beta-lactamases of Bacilli, and the role of a Bacillus secretion vector in the secretion of foreign gene products. This book also gives an account of various facets of Bacillus biology, especially in the identification of promoters, cloning of foreign genes, and selection of expressed gene products.

Genetics and Biotechnology of Bacilli, Volume 2


Book Description

Genetics and Biotechnology of Bacilli, Volume 2 is a collection of papers from the "Fourth International Conference on Bacilli" held in California on June 21-24, 1987. One paper reviews the results of cloning and characterization of genes for secreted enzyme and of genes that control the expression of secreted enzymes in relation with other prokaryotic regulatory systems. Other papers tackle the regulation of gene expression during sporulation, the sigma factors, bacterial toxins, and antibiotic resistance genes. One paper reports that three genes responsible for the code for peptides found in BT cuboidal crystals have been successfully cloned. The three codes have different toxic characteristics in relation to tobacco hornworm larvae or mosquito larvae. Other papers examine replication. Such examination pertains to the two levels of control on the chromosome involved in DNA replication, or to the possible functional importance that several membranes associated DNA subcomplexes can have in Bacillus subtilis, where one of these appear to control initiation. Other papers discus secretion and extracellular enzymes, as well as, the different genetic systems and methods. This collection can prove beneficial for biochemists, micro-biologists, cellular researchers, and academicians involved in the study of cellular biology, microchemistry, or toxicology.

Biology and Biotechnology of Actinobacteria


Book Description

This book provides in-depth insights into the biology, taxonomy, genetics, physiology and biotechnological applications of Actinobacteria. It especially focuses on the latter, reviewing the wide variety of actinobacterial bioactive molecules and their benefits for diverse industrial applications such as agriculture, aquaculture, biofuel production and food technology. Actinobacteria are one of the most promising sources of small bioactive molecules and it is estimated that only a small percentage of actinobacterial bioactive chemicals have been discovered to date. Identifying new diverse gene clusters of biotechnological relevance in the genome of Actinobacteria will be crucial to developing advanced applications for pharmaceutical, industrial and agricultural purposes. The book offers a unique resource for all graduate students, researchers and practitioners in the fields of microbiology, microbial biotechnology, and the genetic engineering of Actinobacteria.







Bacillus


Book Description

The genus Bacillw; has a long history of importance, both from an economic point of view and as a source of experimental microorganisms. This volume critically reviews aspects of identification, molecular biology, and growth that are of impor tance for the current and anticipated future exploitation of members of this group. In addition, the volume includes a chapter on taxonomy, as the importance of good taxonomy is often not fully appreciated; on sporulation, since so many important products are produced concomitantly with this process and we are beginning to understand the mechanisms by which the process is controlled; and, finally, on the cell envelope, as we are only just beginning to appreciate the significance of dif ferences between the cell walls of gram-positive and gram-negative bacteria for productivity and processing. The commercial importance of Bacillus lies mainly in the area of enzyme pro duction for the food, drink, and detergent markets. Increasingly, however, the ability of Bacillus to secrete proteins, coupled with its regulatory acceptability, has resulted in strenuous efforts to develop species of Bacillus as hosts for the produc tion of value-added heterologous proteins. Difficulties have often been encoun tered, indicating a need to divert more resources to improving our understanding of the molecular biology of members of this grou p. Experience with Escherichia coli, a far from ideal organism from a commercial point of view, suggests that an in creased investment in Bacillus is likely ultimately to be productive.

Molecular Biological Methods for Bacillus


Book Description

Molecular Biological Methods for Bacillus Edited by C. R. Harwood, Department of Microbiology, University of Newcastle upon Tyne, UK and S. M. Cutting, The Biological Laboratories, Harvard University, USA This volume represents the first major attempt to produce a compendium of the experimental methods used for the analysis of Bacillus, one of the most important procaryotic genera. Since the pioneering work on the transformation and genetic analysis of Bacillus subtilis by John Spizizen and his colleagues in the late 1950s this microorganism has been extensively studied and is now one of the best understood. More than forty of the world’s leading researchers in the field have generously contributed experimental procedures—devised and used in their laboratories—to this book. The aim throughout has been to present methods as simple step-by-step protocols which have been thoroughly tried and tested. The context in which the methods are used is discussed in detail and relevant information provided on the physiology and genetics of Bacillus. In addition valuable support is provided in the form of troubleshooting tips and advice on safety, the preparation of reagents, and the use of equipment. The book will be invaluable to those working with the genus Bacillus and related genera—both established researchers and those wishing to use this important microorganism for the first time.
