This book explains the main problems of industrial wastewater treatments and how they are being treated by innovative biological processes. The need for clean water in developing countries has become difficult to achieve as a result of globalization and industrialization and  because of an increase in population, urbanization, and per capita water use.

Residential, commercial, industrial, and educational institutions produce immense amounts of wastewater.  Wastewater is treated to extract toxins to produce processed effluent by physical, chemical, and biological processes. Most of these innovative treatment systems are membrane filtration, advanced oxidation processes, and electrochemical approaches, which are strongly committed to offering solutions to help protect public health and the environment.

For wastewater treatment, different forms of bioreactors are used which are reliable, cost-efficient, and effective in removing a wide variety of contaminants.

This book outlines the capacity of various bioreactors that are most widely used for the treatment of different industrial and domestic wastewater, such as a rotating biological contactor, biological fluidized bed reactor, packed bed reactor, membrane bioreactor, continuous stirred tank bioreactor, up-flow anaerobic sludge blanket reactor, and photobioreactor, etc.

Despite this, the acceptance of these technologies and their commercialization on an industrial scale, the performance is still limited. Therefore, a broader use of cost-effective in situ remedial approaches to natural phenomena like bioremediation is needed. The role of numerous bioreactors in industrial effluent treatment has, including recent developments, also been explored in depth. Furthermore, it includes the operational factors affecting their performances, advances in their architectural design, their amalgamation with the existing setup, scale-up studies, life cycle assessment of those reactors, materials and cost analysis, etc. This information helps the reader to understand the insight into the mechanism, pros and cons, moreover efficient utilization, and commissioning of bioreactors.

Antimicrobial peptides (AMPs) have been sought to be a potential alternative to the current arsenal of antibiotics against undesirable microbes. AMPs synthesized by lactic acid bacteria have attracted significant attention due to their strong activity against a broad range of bacteria including pathogens. The bacteriocin (an AMP) has been known to us since early 1928, a year before penicillin was reported. This is possibly due to their narrower activity compared to antibiotics. However, several AMPs having promising activity have been thoroughly characterized in the past few decades. Renewed interest has developed focusing on industrially important bacteriocins produced by lactic acid bacteria. Some of these AMPs are also active against food spoilage and clinically important pathogens. Similar to antibiotics, large-scale intellectual screening is ongoing in the search for novel AMPs with unique properties. Recent research has revealed that AMPs may also play a role in maintaining gut microflora and keeping us protected from food-borne pathogens. The ongoing genomic studies suggest that there may be more such bioactive compounds waiting to be explored. This book provides an overview of the fundamental knowledge accumulated so far regarding the diversity and potential applications of AMPs produced by lactic acid bacteria. This updated reference book on AMPs from lactic acid bacteria is timely, covering the most important achievements in the field and providing the scientific community particularly graduate students, researchers, and clinicians with the latest updates. The goal of this book is to illustrate and detail the findings made so far, debate the state of the art, and draw new perspectives.

This book highlights microbial products and their applications in the health sector. The chapters introduce novel advancements and applications in different pharmaceutical and nutraceutical aspects of applied microbiology. Readers will obtain a detailed overview of the relevance of microbial metabolites to human health and nutrition. Besides knowing the products already developed, they will also get an idea of microbial products currently in the development pipeline and those that are likely to emerge as potential nutraceuticals. Readers will get an interesting and useful perspective on how supplementing food with microbes or their bioactive metabolites can realize the idea of ''food as medicine''. This book introduces the biological activities of various microbial fermentation products, and how they are relevant to mitigating various disease conditions (e.g. neuropathy, diabetes, gut dysbiosis, malnutrition, etc.) in humans. One of the highlights of this volume is the exploration of microbial pigments as potential substitutes for synthetic colorants, offering safer and more sustainable alternatives for the food and healthcare industries. The book has equivalent contributions from experts in academia and industry to fill the communication gap between them. Through this book, readers will gain valuable insights into the historical perspectives, contemporary impacts, and future prospects of microbial applications in health and nutrition. From food preservation to biopharmaceutical production, the potential of microbial products to revolutionize our approach to health and wellness is undeniable.

This book explains the potential value of microbiome and microbiome composition associated with human health and diseases. The opening chapters describe the current state of knowledge regarding the human microbiome structure, function, and diversity. The mechanisms of action and the various putative uses of human microbiome are then examined specific to healthy and disease conditions. Readers will find detailed information on its manipulation of human microbiome studies as well as its applied and translational aspects in the current field. The latest knowledge on probiotics, prebiotics, synbiotics, and postbiotics is presented, and specific cases to date are discussed. This book features knowledge from leading researchers working on different aspects of the human microbiome and its manipulation for better health. Overall, this book is an excellent source for microbiome researchers and students from all levels seeking the most up-to-date advancements in the field and also to point toward the future directions.
