The Molecular Biology of the Bacilli: Volume II is a collection of material relevant to the basic knowledge of the bacillus system and to the development of the bacillus system for industrial applications. This volume presents bacillus research studies on the unique characteristics of bacilli and its interesting comparisons with other bacteria, specifically Escherichia coli. The first four chapters focus on the Bacillus subtilis, specifically the translational specificity, DNA repair, chemotaxis, and sporulation. Chapter 5 discusses the protoplast fusion in bacillus while Chapter 6 delves on the secretion of proteins by bacilli. Chapter 7 explores the function of bacilli as insecticide. Bacillus thuringiensis is also mentioned in this chapter. This topic is further discussed in Chapter 8 where the genetics and molecular biology of B. thuringiensis are discussed. This volume aims to be of help to students and researchers in various fields of biochemistry, genetics, biological sciences, and microbiology.
