This detailed volume provides a toolbox for designing constructs, tackling expression and solubility issues, handling membrane proteins and protein complexes, and exploring innovative engineering of E. coli. The topics are largely grouped under four parts: high-throughput cloning, expression screening, and optimization of expression conditions, protein production and solubility enhancement, case studies to produce challenging proteins and specific protein families, as well as applications of E. coli expression. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Heterologous Gene Expression in E. coli: Methods and Protocols serves molecular biologists, biochemists and structural biologists, those in the beginning of their research careers to those in their prime, to give both an historical and modern overview of the methods available to express their genes of interest in this exceptional organism.

Algae Based Polymers, Blends, and Composites: Chemistry, Biotechnology and Material Sciences offers considerable detail on the origin of algae, extraction of useful metabolites and major compounds from algal bio-mass, and the production and future prospects of sustainable polymers derived from algae, blends of algae, and algae based composites. Characterization methods and processing techniques for algae-based polymers and composites are discussed in detail, enabling researchers to apply the latest techniques to their own work. The conversion of bio-mass into high value chemicals, energy, and materials has ample financial and ecological importance, particularly in the era of declining petroleum reserves and global warming. Algae are an important source of biomass since they flourish rapidly and can be cultivated almost everywhere. At present the majority of naturally produced algal biomass is an unused resource and normally is left to decompose. Similarly, the use of this enormous underexploited biomass is mainly limited to food consumption and as bio-fertilizer. However, there is an opportunity here for materials scientists to explore its potential as a feedstock for the production of sustainable materials. - Provides detailed information on the extraction of useful compounds from algal biomass - Highlights the development of a range of polymers, blends, and composites - Includes coverage of characterization and processing techniques, enabling research scientists and engineers to apply the information to their own research and development - Discusses potential applications and future prospects of algae-based biopolymers, giving the latest insight into the future of these sustainable materials
Fullerenes and nanotubes are two classes of carbon structures or allotropes, which were discovered about 17 years ago. Since that time, many chemical derivatives have been synthesized using fullerenes and nanotubes as building blocks. Particularly promising was the theory that the chemical properties of fullerenes, and certain derivatives, made them likely candidates for anticancer drugs, inhibitors of viruses such as HIV, or even as anti-bacterials. Their cyctotoxicity can also be controlled by specific circumstances. In addition, the funtionalization of nanotubes has not only produced relatively simple derivatives, but also complex hybrids with biological macromolecules, which show unique supramolecular architecture and which are promising in many medical applications. The application of fullerenes and nanotubes in medicine is at the frontier of our knowledge, thus the work in this field represents the basis for future novel developments.
This book covers the nutritional and nutraceutical profiles of a wide range of popularly consumed vegetables and nuts. The first half of the book focuses on popular vegetables, and describes how higher vegetable consumption reduces the risk of diseases ranging from diabetes to osteoporosis, diseases of the gastrointestinal tract, cardiovascular diseases, autoimmune diseases and cancer. The book also includes an interesting section on the antioxidant potential of mushrooms. In turn, the second half discusses the nutritional value of various nuts. Nuts are nutrient-dense foods with complex matrices rich in unsaturated fats, high-quality protein, fiber, minerals, tocopherols, phytosterols and phenolics. The respective chapters illustrate how the consumption of nuts could ward off chronic diseases like hypertension, cancer, inflammation, oxidative stress, high blood pressure, coronary heart disease etc. In order to effectively promote vegetable and nut consumption, it is necessary to know and understand the nutritional and nutraceutical profiles of vegetables & nuts. Given its scope, the book will be of interest to students, researchers, food scientists, olericulturists, dietitians and agricultural scientists alike. Those working in the vegetable and nut processing industries, horticultural departments and other agricultural departments will also find the comprehensive information relevant to their work.
Enzymatic catalysis has gained considerable attention in recent years as an efficient tool in the preparation of natural products, pharmaceuticals, fine chemicals, and food ingredients. The high selectivity and mild reaction con- tions associated with enzymatic transformations have made this approach an attractive alternative in the synthesis of complex bioactive compounds, which are often difficult to obtain by standard chemical routes. However, the maj- ity of organic compounds are not very soluble in water, which was traditi- ally perceived as the only suitable reaction medium for the application of biocatalysts. The realization that most enzymes can function perfectly well under nearly anhydrous conditions and, in addition, display a number of useful properties, e. g. , highly enhanced stability and different selectivity, has d- matically widened the scope of their application to the organic synthesis. Another great attraction of using organic solvents rather than water as a reaction solvent is the ability to perform synthetic transformations with re- tively inexpensive hydrolytic enzymes. It is worth reminding the reader that in vivo, the synthetic and hydrolytic pathways are catalyzed by different enzymes. However, elimination of water from the reaction mixture enables the “reversal” of hydrolytic enzymes and thus avoids the use of the expensive cofactors or activated substrates that are required for their synthetic count- parts.
