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
"This monograph contains four chapters, each of which provides a different perspective on biopesticides. Chapter One concerns the use of biopesticides in sustainable agriculture, including the interactions between biopesticides and chemical pesticides, production issues, and opportunities for future research. Chapter Two describes the bottom-up approach for using Bacillus thuringiensis (Bt) as a biopesticide and for enhancing host plant resistance against major foliage feeders through deployment of suitable cry genes. Chapter Three reviews strategies for mitigating the spread of Bt resistance and improving insecticidal activity against Bt-susceptible pests. Lastly, Chapter Four aims to revise, debate, and evaluate the effects of Bt as phosphate solubilizing and phosphorus uptake by plant establishment"--

Book Description
Megaplasmids are extrachromosomal genetic elements in the size range of 100 kb and larger. They are found in physiologically and phylogenetically diverse groups of bacteria and archaea. By definition, megaplasmids are not essential for the viability of their hosts under all growth conditions, but paradoxically many megaplasmids carry the genetic information for the defining and characteristic traits of the organism in which they reside. Microbial Megaplasmids reviews our knowledge of the extensively studied representatives, such as the catabolic plasmids of the pseudomonads, the rhizobial Sym plasmids, the Ti plasmids of the genus Agrobacterium and the giant enterobacterial virulence plasmids. It also presents snapshots of more recently discovered megaplasmids. The contribution of megaplasmids to the biology of their hosts is described, highlighting the interactions between megaplasmid and chromosomal genes.

Book Description
Mosquitoes and black flies are a constant threat to health and comfort, yet the modern chemical pesticides used to control them have cre ated serious ecological problems. Populations of resistant mosquitoes and black flies have evolved, beneficial insects and natural predators have been destroyed, and environmental pollution has increased worldwide. Therefore, scientists have energetically sought new, environmentally safe technologies to combat mosquitoes and black flies and the diseases they carry. Among the most effective alternative means of controlling these pests are the highly spe cific microbial agents derived from Bacillus tburingiensis or Bacillus spbaericus. The microbial control of mosquitoes and black flies is a very important, rapidly developing area of science. Entomologists and microbiologists have already achieved spectacular successes using B. tburingiensis and B. spbaericus against these pests. Recent discoveries of new bacterial isolates specific to new hosts and recent genetic improvements in these isolates have created the potential for wide-scale use of these biological control agents. Efficient microbial control of mosquitoes and black flies can now be achieved, but a proper knowledge of factors relating to the safe and effective use of these biological control agents is necessary. The efficacy of B. tburingiensis and B. spbaericus is influenced by the inherent differential tol erance of the target mosquitoes or black flies, by the formulation technology and application of these agents, and by environmental factors, especially sun light and temperature.

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
In Chapter One, André L de A Melo, Ph.D. discusses the spore-forming bacterium Bacillus thuringiensis and its uses as a bio-insecticide, also touching on ways to combat insect resistance. In Chapter Two, Karim Ennouri proposes the bacterium Bacillus thuringiensis as an important biopesticide because of the entomopathogenic effect of delta-endtoxins as well as its efficiency against insects resistant to chemical insecticides. In conclusion, Rafael C Lajmanovich, Candela S Martinuzzi, Carlina Colussi, Paola M Peltzer, Agustín Bassó, Andrés M Attademo, and Lucila M Curi present a study exploring the impact of a GM Bt-soybean-based diet, as opposed to a lettuce diet, on tadpoles.
