Book Description
Microbial relationships with all life forms can be as free living, symbiotic or pathogenic. Human beings harbor 10 times more microbial cells than their own. Bacteria are found on the skin surface, in the gut and other body parts. Bacteria causing diseases are the most worrisome. Most of the infectious diseases are caused by bacterial pathogens with an ability to form biofilm. Bacteria within the biofilm are up to 1000 times more resistant to antibiotics. This has taken a more serious turn with the evolution of multiple drug resistant bacteria. Health Departments are making efforts to reduce high mortality and morbidity in man caused by them. Bacterial Quorum sensing (QS), a cell density dependent phenomenon is responsible for a wide range of expressions such as pathogenesis, biofilm formation, competence, sporulation, nitrogen fixation, etc. Majority of these organisms that are important for medical, agriculture, aquaculture, water treatment and remediation, archaeological departments are: Aeromonas, Acinetobacter, Bacillus, Clostridia, Enterococcus, Pseudomonas, Vibrio and Yersinia spp. Biosensors and models have been developed to detect QS systems. Strategies for inhibiting QS system through natural and synthetic compounds have been presented here. The biotechnological applications of QS inhibitors (QSIs) in diverse areas have also been dealt with. Although QSIs do not affect growth and are less likely to impose selective pressure on bacteria, however, a few reports have raised doubts on the fate of QSIs. This book addresses a few questions. Will bacteria develop mechanisms to evade QSIs? Are we watching yet another defeat at the hands of bacteria? Or will we be acting intelligently and survive the onslaughts of this Never Ending battle?

Book Description
Antibiotic resistance in pathogen microorganisms is a major global concern, especially the formation of biofilms. Quorum quenching has been practically used to control biofilm growth, and this indicates a promising hope for the development of new drugs for the control of biofilm-forming pathogens. This book provides a single source of information about two issues: the biology of quorum sensing and quorum quenching, and the perspectives of quorum quenching in new drug development. The text covers the latest literature from the last ten years and insights into quorum quenching and its need in medicine as an anti-virulence strategy. Features: Exclusively focuses on quorum quenching and its ability to be used as an alternative to antibiotics in the control of multidrug-resistant pathogens. Reviews the latest literature and case studies of the last ten years in the field of quorum sensing and quorum quenching. Promotes a new approach to the development of the next generation of antibacterial drugs. In the wake of rising antibiotic drug resistance, it is crucial to develop an alternative approach to control bacterial infection diseases and quorum quenching appears to be a promising strategy in the development of new medicines.

Book Description
Antibiotic resistance is a global health concern. Strains of pathogenic microorganisms that have developed resistance to multiple antibiotics, such as MRSA, are extremely difficult to treat, and alternative methods for tackling pathogenic microorganisms are in demand. One potential target for new therapeutics is inhibition of quorum sensing: how microorganisms communicate and form biofilms in a density-dependent manner. Inhibiting this system via ‘quorum quenching’ (QQ) is a promising route to new pharmaceuticals and for controlling biofilm formation and growth. Quorum sensing also provides interesting possibilities in synthetic biology for producing novel products, biosensors, bioactive molecules, and so on. This book covers the biology of quorum sensing and quenching, and potential sources of QQ enzymes and other inhibitors, as well as an overview of their mechanism and potential biotech applications. The book also covers the potential for new drug development from QQ, covering a range of related topics including protein engineering, imaging and computational studies, and integrated systems. This book is an ideal companion to researchers in chemical biology and medicinal chemistry, particularly those interested in biofilm formation, quorum sensing, novel antimicrobial development, synthetic biology and enzymology.

Book Description
This book discusses the practical applications of quorum sensing inhibitors for both human and plant health. Quorum sensing inhibitors that disrupt microbial biofilms can be employed to treat bacterial infections. The book describes the various bioactive molecules that can serve as quorum sensing inhibitors to combat deadly bacterial infections, in addition to several synthetic quorum sensing inhibitors. Quorum sensing is the mechanism through which bacteria develop antibiotic resistance. Intended to provide a clearer understanding of the practical applications of quorum sensing inhibitors, the book details how the problem of antibiotic resistance can be countered through the intelligent application of quorum sensing inhibitors.

Book Description
This book delves into the biotechnological applications of Quorum sensing (QS)- a peculiar gene-regulatory process of some microorganisms. Quorum Sensing allows a large bacterial population to work together in a coordinated manner to carry out metabolic activities, which individual bacterium cannot. The different chapters describe how, associating bioremediation process with energy generation is an economical proposal, for reducing pollution and managing biowastes. The book discusses how QS can be exploited for biotechnological applications in generating bioproducts, bioenergy, bioremediation, biosensors, health and agricultural activities. It further highlights how QS is becoming an integral part of synthetic biology for genetic circuits for producing: (i) novel products, (ii) biosensors, (iii) bioactive molecules, etc. The book is divided into different sections for a clear understanding of the applicability of QS in, the Environment, Energy, Agriculture and Health sectors.
