This book was released on 2016-08-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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?

This book was released on 2019-01-28 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book illustrates the importance and significance of Quorum sensing (QS), it’s critical roles in regulating diverse cellular functions in microbes, including bioluminescence, virulence, pathogenesis, gene expression, biofilm formation and antibiotic resistance. Microbes can coordinate population behavior with small molecules called autoinducers (AHL) which serves as a signal of cellular population density, triggering new patterns of gene expression for mounting virulence and pathogenesis. Therefore, these microbes have the competence to coordinate and regulate explicit sets of genes by sensing and communicating amongst themselves utilizing variety of signals. This book descry emphasizes on how bacteria can coordinate an activity and synchronize their response to external signals and regulate gene expression. The chapters of the book provide the recent advancements on various functional aspects of QS systems in different gram positive and gram negative organisms.

Download or read book Biocommunication of Archaea written by Guenther Witzany and published by Springer. This book was released on 2017-09-27 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Archaea represent a third domain of life with unique properties not found in the other domains. Archaea actively compete for environmental resources. They perceive themselves and can distinguish between ‘self’ and ‘non-self’. They process and evaluate available information and then modify their behaviour accordingly. They assess their surroundings, estimate how much energy they need for particular goals, and then realize the optimum variant. These highly diverse competences show us that this is possible owing to sign(aling)- mediated communication processes within archaeal cells (intra-organismic), between the same, related and different archaeal species (interorganismic), and between archaea and nonarchaeal organisms (transorganismic). This is crucial in coordinating growth and development, shape and dynamics. Such communication must function both on the local level and between widely separated colony parts. This allows archaea to coordinate appropriate response behaviors in a differentiated manner to their current developmental status and physiological influences. This book will orientate further investigations on how archaeal ecosphere inhabitants communicate with each other to coordinate their behavioral patterns and whats the role of viruses in this highly dynamic interactional networks.

Download or read book Fundamentals of and Applications Based on Quorum Sensing and Quorum Sensing Interference written by Cristina García-Aljaro and published by Frontiers Media SA. This book was released on 2020-01-23 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background Bacteria use quorum sensing (QS) circuits to coordinate various activities (among which biofilm formation and the expression of virulence factors) based on the presence of signaling molecules. Different families of signal molecules have been identified in Gram positive and Gram negative bacteria (e.g. autoinducer peptides and acyl homoserine lactones). Similarly, different quorum sensing antagonists interfering with these system have been found in nature, promoting a new and promising field of research, quorum sensing interference. One of the most intensively studied applications of quorum sensing interference is its use as an alternative or synergycally with antibiotics to fight (antibiotic-resistant) bacterial pathogens. Many studies have been published claiming quorum sensing inhibitory activity of natural and synthetic compounds. However, after decades of research, several questions regarding the suitability of this approach to fight bacterial pathogens remain unanswered, including the risk that pathogens will develop resistance against quorum quenching. Meanwhile, the interest in quorum sensing has increased considerably, and this has broadened the fields where it can find biotechnological, environmental and industrial applications, such as anti biofouling, steering fermentations, bioremediation and wastewater treatment. Goal and scope The goal of this Research Topic is to broaden the knowledge of the phenotypes regulated by quorum sensing and the advances in quorum sensing interference. Deciphering microorganism language and the different phenotypes regulated by microbial signalling systems is a frontier for the development of new tools for the management of microorganisms to fulfil human needs with a broad application in different areas such as medicine, environmental sciences and industry.

Download or read book The Perfect Slime written by Hans-Curt Flemming and published by IWA Publishing. This book was released on 2016-09-15 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Perfect Slime presents the latest state of knowledge and all aspects of the Extracellular Polymeric Substances, (EPS) matrix – from the ecological and health to the antifouling perspectives. The book brings together all the current material in order to expand our understanding of the functions, properties and characteristics of the matrix as well as the possibilities to strengthen or weaken it. The EPS matrix represents the immediate environment in which biofilm organisms live. From their point of view, this matrix has paramount advantages. It allows them to stay together for extended periods and form synergistic microconsortia, it retains extracellular enzymes and turns the matrix into an external digestion system and it is a universal recycling yard, it protects them against desiccation, it allows for intense communication and represents a huge genetic archive. They can remodel their matrix, break free and eventually, they can use it as a nutrient source. The EPS matrix can be considered as one of the emergent properties of biofilms and are a major reason for the success of this form of life. Nevertheless, they have been termed the “black matter of biofilms” for good reasons. First of all: the isolation methods define the results. In most cases, only water soluble EPS components are investigated; insoluble ones such as cellulose or amyloids are much less included. In particular in environmental biofilms with many species, it is difficult to impossible isolate, separate the various EPS molecules they are encased in and to define which species produced which EPS. The regulation and the factors which trigger or inhibit EPS production are still very poorly understood. Furthermore: bacteria are not the only microorganisms to produce EPS. Archaea, Fungi and algae can also form EPS. This book investigates the questions, What is their composition, function, dynamics and regulation? What do they all have in common?
