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.




Bacilli in Agrobiotechnology


Book Description

The third volume of the series ‘Bacilli and Agrobiotechnology’ is comprised of 25 chapters that bring a unique perspective to the readers about Bacillus-mediated biotic and abiotic plant stress tolerance, bioremediation and bioprospecting. These chapters are prepared by the leading scientists of global repute. The negative impacts of agrochemicals such as chemical fertilizers and pesticides on human health and environment are paramount. Bacillus and allied genera of beneficial plant-associated microbes are presenting beacon of hope to the farmers, plant scientists and stewards of environment. Several chapters of this volume focus on the induction of various signaling pathways in plants by Bacillus spp. to alleviate biotic and abiotic stresses impacted by global climate change Agricultural lands contaminated with heavy metals affect the ecological food chain starting from crop cultivation. How the toxic effects of trace metals originating from industrial effluents and agrochemicals can be remediated? This book addresses how to overcome these issues by applying elite strains of Bacillus. Bioprospecting is a systematic and organized search for conversion of bioresources to industrially important products by utilizing microbe-derived metabolites. This volume is enriched by including the bioprospecting aspects mediated by Bacillus spp. with novel insights.







Genetics and Biotechnology of Bacilli


Book Description

Genetics and Biotechnology of Bacilli, Volume 3 covers the proceedings of the Fifth International Conference on Genetics and Biotechnology of Bacilli, held on July 9-12, 1989 at the Asilomar Conference Center, Pacific Grove, California. It summarizes the remarkable progress made in the genetics and biotechnology fields of Bacilli. It is organized into four parts, encompassing 43 chapters, which focus on gene regulation and structure, enzyme structure, Bacillus thuringiensis toxins, and stationary phase gene regulation. Part I covers topics related to gene regulation and structure of Bacilli, such as control of gene expression, mutation, genetic organization, DNA sequence analysis, and identification of transcript units. It also discusses gene replication in Bacillus subtilis plasmids, levanase operon of B. subtilis, and characterization of global regulon in B. subtilis. The next part of this book focuses on the structure of various enzymes found in B. subtilis, including alpha amylases, subtilisin, alkaline phosphatase, and levansucrase. Part III discusses the generation of functional B. thuringiensis toxin hybrid genes, regulation of crystal protein gene promoters, toxicity of B. thuringiensis delta-endotoxin, and insecticidal activity of chimeric protoxins. The concluding part covers the aspects of signal transduction, regulation of differential gene expression during B. subtilis sporulation, and gene cloning and deletion for extracellular proteases of B. subtilis. It also discusses genetic and biochemical aspects of protein phosphorylation; properties of B. subtilis spores; control of stationary phase gene expression; and the novel regulatory gene, senS, of B. subtilis. This book is a valuable source of information for microbiologists, research biologists, and Bacilli enthusiasts.




The Prokaryotes


Book Description

The revised Third Edition of The Prokaryotes, acclaimed as a classic reference in the field, offers new and updated articles by experts from around the world on taxa of relevance to medicine, ecology and industry. Entries combine phylogenetic and systematic data with insights into genetics, physiology and application. Existing entries have been revised to incorporate rapid progress and technological innovation. The new edition improves on the lucid presentation, logical layout and abundance of illustrations that readers rely on, adding color illustration throughout. Expanded to seven volumes in its print form, the new edition adds a new, searchable online version.




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.




Bacilli and Agrobiotechnology: Phytostimulation and Biocontrol


Book Description

The Gram-positive and spore-forming Bacilli are the most dominant group of bacteria that exist in various ecological niches on the earth. They represent one of the most important unmapped pools of biodiversity with immense potential of applications in agriculture, environment, and industry. As these bacteria are highly tolerant to stressful environment and enhance plant tolerance to harsh environment such as salinity, drought, and heavy metal toxicity, plant-associated Bacilli have high potential for promoting sustainable crop production. Many species of Bacilli are being commercially used as phytostimulator and biofertilizer. Some of them are applied as biopesticide for protecting crop plants from phytopathogens and insect pests. The Bacillus-based products are becoming popular in ecologically sound and climate resilient agricultural production system. In fact, Bacillus and allied species based formulations are already dominating the biopesticides market, although, to compete with other formulations and chemical alternatives, the biology of Bacillus had to be understood from perspective of such applications. Our understanding of the biology and molecular-basis of the beneficial effects of plant-associated Bacilli has greatly been progressed in recent years through genomics, metagenomics, post-genomics and metabolomics studies. The volume two of the series Bacilli and Agrobiotechnology comprehensively reviews and updates current knowledge of Bacilli as phytostimulant and biological control of plant pests. Better understanding the biology, ecology and mechanism of action of the beneficial strains of Bacilli will play a role in the development of products to support green biotechnology in agriculture and industries.
