Microbial lipases are industrially important and have gained attention due to their stability, selectivity, and broad substrate specificity. Lipases are used as medicine, and they also aid in indigestion, heartburn, allergy to gluten in wheat products (celiac disease), Crohn's disease, and cystic fibrosis. This volume considers the industrial demand for new sources of lipases with different catalytic characteristics that stimulate the isolation, growth, and development of new microbial strains. The volume narrates the challenging metagenomic approach with the isolation of the lipase gene, its cloning into Escherichia coli, culture of the recombinant bacteria, and extraction and assessment of the lipase enzyme. Lipase-producing bacteria are available in different habitats, such as industrial wastes, vegetable oil processing factories, dairy plants, and soils contaminated with oil and oil seeds, among others. This volume is the effort of the authors to document the scientific findings carried out over the last eight years in the area of un-culturable soil microorganisms. The book presents the physic-chemical features of lipases and their specific applications in different commercial industries. The in-depth study looks at metagenomics for lipases from all angles and provides a truly informative resource. It describes the biochemical characterization of lipase enzymes with the high activity in the presence of 1% tributyrin. A wide review has been presented in the book on lipase enzymes purified from a large collection of microbes present in soil, seawater, waste-dumping sites, animal systems (including human beings), and the atmosphere. Stability of enzymes over changing environments of the industry is indeed a big issue, and the book deals at length with the changing temperatures and pH and metal ion concentrations.

Bacterial biopolymers are a competitive new area of research, having potential application in agriculture, petroleum exploration, and use as biodegradable plastics. This new volume provides comprehensive coverage of bacterial biopolymers. The book elucidates on the main classes of bacterial biopolymers—polysaccharides and polyesters or polyhydroxyalkanoates (PHAs)—along with their definition, classification, detection, extraction, characterization, fermentation process, structure and properties, their applications and uses, functions, and more. The chapters discuss Detection, extraction, and characterization of bacterial biopolymers Molecular identification of bacterial isolates The fermentation process Structure and properties of PHAs Biochemical characterization of the PHA-producing bacterial strains Applications of PHA Biopolymer-producing bacteria and the genes In vitro biodegradation study of PHA film by soil microorganisms PHAs for enhancing the stability of colloidal silver nanoparticles (SNP) This volume is an important source of information on the concerned bacteria, the biochemical characteristics of biopolymers, and their potential use. The author hopes that scholars will be encouraged to take up meaningful research in the area; that teachers will find the book to be helpful in conveying the intricacies of bacterial biopolymers and their possible production and use; and that the procedures described in the book will help research workers to derive sought-for results.
