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.

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.

Bacillus subtilis is a motile gram-positive bacterium widespread in the soil and the gut of animals which has been reported to cause opportunistic infections in immunocompromised patients. In Bacillus subtilis: Morphology, Functions and Role in Disease Management, the authors begin by outlining the main features of chemotaxis as a behaviour, then reviewing the molecular machinery Bacillus subtilis uses to sense and respond to chemical cues. Following this, the authors discuss how bacterial biofilms can form on biotic and abiotic surfaces, developing various reversible and irreversible stages depending on environmental conditions. An important characteristic of biofilm is the extracellular matrix, which is usually formed by exopolysaccharide and extracellular proteins by Bacillus subtilis. Next, this compilation highlights the key features in Bacillus subtilis lipopeptides as eco-friendly controllers of plant pathogens. Currently, phytopathogens impact all agricultural systems, leading to economic losses worldwide. The closing chapter discusses NKCP®, a novel dietary supplement derived from traditional Japanese traditional food, which improved patients symptoms and blood pressure by improving blood flow through antithrombotic and fibrinolytic properties.
