Applied biocatalysis and biotransformation, that is, the use of enzymes and whole-cell systems in manufacturing processes for synthetic purposes, has been experiencing a clear boom in recent years, which has led to the start of the so-called “fourth wave”. In fact, the latest advances in bioinformatics, system biology, process intensification, and, in particular, enzyme-directed evolution (encouraged by the 2018 Nobel Prize awarded to F. Arnold), are widening the range of the efficacy of biocatalysts and accelerating the rate at which new enzymes are becoming available, even for activities not previously known. European scientists have been very actively involved in different aspects of this field. Nine contributions dealing with different aspects of applied biocatalysis developed by European researchers are gathered in this Special Issue
This book provides an overview of the different aspects of microbial bioconversion methodologies for valorization of underutilized wastes of varied nature. It covers microbiological/biotechnological aspects, environmental concerns, bioprocess development, scale-up aspects, challenges, and opportunities in microbial valorization at commercial scale. It explains sustainable microbiological processes for bioconversion and valorization of the wastes for production of various products of commercial interests, including biofuels, bioenergy, and other platform chemicals. The book • presents potential biotechnological topics and strategies for the valuation of agricultural waste materials; • pro...
Das Gesamtgebiet der Biokatalyse mit allen seinen Facetten -- Mikrobiologie, Enzymologie, Molekularbiologie, Strukturbiologie, organische Chemie -- wird in diesem interdisziplinär angelegten Werk beleuchtet; insbesondere geht es um enzymatische Katalysen und Ganzzell-Katalysen. Ein Schwerpunkt liegt dabei auf der Entwicklung hochselektiver, umweltfreundlicher Prozesse zur Synthese wichtiger Verbindungsklassen.
Recent developments in genetic engineering and protein chemistry are bringing ever more powerful means of analysis to bear on the study of enzyme structure. This volume reviews the most important types of industrial enzymes. In a balanced manner it covers three interrelated aspects of paramount importance for enzyme performance: three-dimensional protein structure, physicochemical and catalytic properties, and the range of both classical and novel applications.
Bioreactor Technology in Food Processing brings peculiarities, specificities, and updates on bioreactors and bioprocesses related to food and beverage production. The 26 chapters of this book are the result of the participation of more than 70 professionals, including professors, researchers, and experts from the industrial sector from different countries around the world. The chapters cover such topics as history, classification, scale-up, analytical tools, and mathematical and kinetic models for the operation of bioreactors in the food industry. In addition, chapters detail the characteristics of bioreactors for the production of food (bread, cheese, and coffee fermentation) and fermented ...
Honey bees are social insects; they live together in large, well-organized family groups comprising three castes: queen (fertile female), workers (sterile females) and drones (males). During honey flow season, there is a considerable increase in the foraging activity of the workers and in the rate of egg laying by the queen. Sex determination in honey bees involves a multi-allelic locus, such that homozygotes develop as males and heterozygotes as females, whereas diet quality influences the caste determination in honey bees. Like all living organisms, honey bees can be infested with diseases and pests. Some of these are more deleterious to bee colonies than others, but it is important for th...
Enzyme Technology is one the most promising disciplines in modern biotechnology. In this book, the applications of a wide variety of enzymes are highlighted. Current studies in enzyme technology are focused towards the discovery of novel enzymes (termed “bio-discovery” or “bio-prospecting”) and the identification and elucidation of novel pathways of these novel enzymes with emphasis on their industrial relevance. With the development of molecular techniques and other bioinformatics tools, the time to integrate this subject with other fields in the life sciences has arrived. A rapid expansion of the knowledge base in the field of enzyme biotechnology has occurred over the past few yea...
This book is a valuable reference that discusses green technologies, like enzyme technologies, to meet the ever-growing demand of nutraceuticals and functional foods. Microorganisms like bacteria (lactic acid bacteria, Bacillus species), yeasts, and filamentous fungi have been exploited for food preparations globally. Microbial Enzymes in Production of Functional Foods and Nutraceuticals discusses how to use them commercially. Chapters include enzyme sources, processing, and the health benefits of microbial enzymes. Other interesting Chapters include the application of metagenomics and the molecular engineering of enzymes. This book is useful for students, academicians, and industry experts in food science and applied microbiology.
Reactive Oxygen Species (ROS) are molecules generated naturally during cellular metabolic processes. They act as signaling agents that oversee specific biochemical pathways, playing a vital role in cell function and survival. However, an imbalance in ROS signaling or excessive ROS production can have harmful effects on the pathophysiology of diseases. ROS are crucial to cell signaling and are involved in various physiological processes. They modulate gene expression, regulate cell cycle progression, and influence immune responses. Although ROS are essential for normal cellular functions, an overabundance of these molecules can lead to oxidative stress, causing DNA damage, lipid peroxidation,...
