Book Description
Polysaccharides provides information pertinent to the fundamental aspects of the chemistry of polysaccharides. This book discusses the methods used for the isolation, purification, and structural determination of the various types of polysaccharide. Organized into 14 chapters, this book begins with an overview of the almost universal occurrence of natural macromolecules in living organisms where they form a variety of functions. This text then examines the isolation of polysaccharides, which involves solubilization in aqueous solvents or in dipolar aprotic solvents. Other chapters consider the industrial applications of polysaccharides and of their derivatives. This book discusses as well the procedure for the isolation of wood polysaccharides, which involves the preparation of a holocellulose by the selective solubilization of the lignin. The final chapter deals with the classes of complex natural polymers in which the nature of the linkage of sugar units to other structural units have been established. This book is a valuable resource for biologists.

Book Description
Despite of the efforts of pharmaceutical researchers to find new medicaments, nature offers many substances with healing properties—beta-glucans belong to this group of compounds. The second volume of the e-book series, Biology and Chemistry of Beta-Glucan, provides new knowledge about these important polysaccharides. In order to understand the role of beta-glucans, it is necessary to control the purity and to determine their composition and structure. This volume presents modern chemical and separation methods which are applied in structural analysis of glucans. As a result of structural analyses, it can be concluded that beta-glucans of different origin vary in chain length, number and types of branching. The book further discusses the biological effects of tailored oligomers and synthetic beta-glucans, including innovative use of enzymatic processes in the synthesis of these compounds. This volume also discusses a hypothesis of beta-glucans’ increasing impact on the photodynamic therapy. In spite of many scientific papers describing the positive role of beta-glucans in protection against diseases, certain epidemiological data suggest that specific illnesses can be related to beta-glucan exposure. The fact of whether or not beta-glucan is an accompanying substance of these biologically active agents is also questioned. Biology and Chemistry of Beta-Glucan: Volume 2 focuses on the strictly scientific basis on the effects of beta-glucan on human health as well as other possibilities of beta-glucan application, such as protection of aquaculture against diseases.

Book Description
The global human population will reach nine billion by 2050, and seafood is projected to be the primary food source to sustain such a large population. According to a recent World Bank report, aquaculture will be the prime source of seafood by 2030. Tilapia is one of the promising species for commercial aquaculture and one of the second most farmed fish worldwide. Given the issues raised by Antibiotic misuse in intensive aquaculture, such as the occurrence of resistant bacteria, it is necessary to develop environment-friendly strategies that could be used to improve production in a sustainable manner. Also, there is a need to establish the best aquaculture practice (BAP) approaches to avoid significant disruption to the ecosystem, the loss of biodiversity, and substantial pollution impact on the environment. The book covers the recent findings regarding sustainable tilapia farming through environment-friendly approaches. This book contains chapters that cover the current status of world tilapia farming and the concept of sustainability of tilapia culture (Chap. 1). Chap. 2 discusses the health management of tilapia with a particular focus on various diseases and treatments. Chap. 3 provides an updated view of the possible effects of feed additives on tilapia reproductive performance. Chap. 4, 5, and 6 cover the recent findings on the gut microbiota of tilapia with a particular focus on structure and modulation. Chap. 7 focuses on the use of medicinal plants for sustainable tilapia farming. Chap. 8 provides insights into the application of alternative protein sources to decrease fish meal consumption. Chap. 9 highlights the importance of culture systems for the development of sustainable tilapia aquaculture. We believe the current book will be very helpful to academics, researchers, and policy-makers in aquaculture.

Book Description
The concept of a circular economy relies on waste reduction, valorization, and recycling. Global trends for “green” synthesis of chemicals have positioned the field of enzyme technology and biocatalysis (multi-enzymes and whole-cells) as an alternative for the synthesis of more social- and environmentally-responsible bio-based chemicals. Recent advances in synthetic biology, computational tools, and metabolic engineering have supported the discovery of new enzymes and the rational design of whole-cell biocatalysts. In this book, we highlight these current advances in the field of biocatalysis, with special emphasis on novel enzymes and whole-cell biocatalysts for applications in several industrial biotechnological applications.

Book Description
The extracellular matrix (ECM) is an acellular three-dimensional network composed of proteins, glycoproteins, proteoglycans and exopolysaccharides. It primarily serves as a structural component in the tissues and organs of plants and animals, or forms biofilms in which bacterial cells are embedded. ECMs are highly dynamic structures that undergo continuous remodeling, and disruptions are frequently the result of pathological processes associated with severe diseases such as arteriosclerosis, neurodegenerative illness or cancer. In turn, bacterial biofilms are a source of concern for human health, as they are associated with resistance to antibiotics. Although exopolysaccharides are crucial for ECM formation and function, they have received considerably little attention to date. The respective chapters of this book comprehensively address such issues, and provide reviews on the structural, biochemical, molecular and biophysical properties of exopolysaccharides. These components are abundantly produced by virtually all taxa including bacteria, algae, plants, fungi, invertebrates and vertebrates. They include long unbranched homopolymers (cellulose, chitin/chitosan), linear copolymers (alginate, agarose), peptoglycans such as murein, heteropolymers like a variety of glycosaminoglycans (hyaluronan, dermatan, keratin, heparin, Pel), and branched heteropolymers such as pectin and hemicellulose. A separate chapter is dedicated to modern industrial and biomedical applications of exopolysaccharides and polysaccharide-based biocomposites. Their unique chemical, physical and mechanical properties have attracted considerable interest, inspired basic and applied research, and have already been harnessed to form structural biocomposite hybrids for tailor-made applications in regenerative medicine, bioengineering and biosensor design. Given its scope, this book provides a substantial source of basic and applied information for a wide range of scientists, as well as valuable textbook for graduate and advanced undergraduate students.
