Book Description
Bacillus thuringiensis (Bt) has been used as a biopesticide in agriculture, forestry and mosquito control because of its advantages of specific toxicity against target insects, lack of polluting residues and safety to non-target organisms. The insecticidal properties of this bacterium are due to insecticidal proteins produced during sporulation. Despite these ecological benefits, the use of Bt biopesticides has lagged behind the synthetic chemicals. Genetic improvement of Bt natural strains, in particular Bt recombination, offers a promising means of improving efficacy and cost-effectiveness of Bt-based bioinsecticide products to develop new biotechnological applications. On the other hand, the different Bacillus species have important biotechnological applications; one of them is carried out by producing secondary metabolites, which are the study object of natural product chemistry. The amazing structural variability of these compounds has attracted the curiosity of chemists and the biological activities possessed by natural products have inspired the pharmaceutical industry to search for lead structures in microbial extracts. Screening of microbial extracts reveals the large structural diversity of natural compounds with broad biological activities, such as antimicrobial, antiviral, immunosuppressive, and antitumor activities that enable the bacterium to survive in its natural environment. These findings widen the target range of Bacillus spp., in special B. thuringiensis, besides insecticidal activity and help people to better understand its role in soil ecosystem.

Book Description
Make the right decisions when it comes to pest control in agriculture! Bacillus thuringiensis: A Cornerstone of Modern Agriculture explores the impact that one of the most prominent biologically based pesticides has had on pest control technology—and the issues that surround its use. The book examines the development, use, and management of technologies derived from Bacillus thuringiensis (Bt), addressing the health, economic, environmental, and social concerns generated by the deployment of genetically engineered crops. Authors representing a diverse cross section of the international scientific community contribute review articles and research findings that address the use of Bt in microbial formulations and transgenic crops, technological advances in the genetic engineering of plants, advances in methodologies, and improved agricultural practices and productivity through the use of Bt cotton. Bacillus thuringiensis: A Cornerstone of Modern Agriculture examines the vital issues surrounding this Gram-positive bacterium. Contributors from academia, government, and industry address the safety of Bt for human consumption, its effects on non-target organisms, the role of microbial Bt products in crop production in the United States, and the utility and management of transgenic plants. The book also explores: engineering Bt transgenic rice for insect pest protection the Bt potato in developing countries Bt expression in sugarcane and cauliflower a comparative analysis of Bt cotton in Argentina the ecological impact, gene expression, and current resistance management requirements of Bt cotton in the United States and much more! Bacillus thuringiensis: A Cornerstone of Modern Agriculture is an essential resource for advanced students and technical specialists working in agriculture, biotechnology, entomology, pest management, and crop sciences. Stakeholders will also find it invaluable in regulatory decision making about genetically engineered crops, pesticide use, and crop protection.

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.

Book Description
Entomopathogenic bacteria (Bacillus thuringiensis and B. sphaericus) are increasingly used as biopesticides to control larval insect populations which are either agricultural or forestry pests and to reduce those which as adults are vectors of severe human diseases. This new book, the first since 1993 to address all aspects of entomopathogenic bacteria, provides undergraduate and graduate students as well as research scientists with a complete, modern view of this important group of bacteria. The authors, chosen for their sustained contributions to the field, cover both fundamental and applied research in this area. The main topics include bacterial ecology and taxonomy, toxin diversity, activity and mode of action, regulation and environment of the genes, safety and ecotoxicology, production and field application of the bacteria, and outbreaks of resistant populations. The book concludes with the most recent data obtained on transgenic biotechnology and addresses environmental impact issues.
