Book Description
The lux genes of Vibrio fischeri encode the ability of this marine bacterium to produce light. V. fischeri occurs at high density in specialized light-emitting organs of certain marine fish, where the light produced is used by the fish. V. fischeri is also found in seawater, where it exists as a member of the bacterioplankton. In the planktonic habitat light-production is not useful and in fact V. fischeri possesses a genetic control mechanism which enables light production when the bacteria exist in the symbiotic state but does not allow synthesis of the light-emitting system when V. fischeri is in the planktonic habitat. This regulatory phenomenon is termed auto induction, and the aim of this research is to fully elucidate the mechanism of auto induction. Specific objectives of this research effort include a structure/function analysis of the sensory receptor; the LuxR protein, purification of the LuxR protein and development of a defined in vitro assay for studying lux gene transcription. Keywords: Maine bacteria; Symbiosis genes; Gene regulation; Auto induction; Luminescence; Chemical communication. (KT).

Book Description
Quorum sensing (QS) describes a chemical communication behavior that is nearly universal among bacteria. Individual cells release a diffusible small molecule (an autoinducer) into their environment. A high concentration of this autoinducer serves as a signal of high population density, triggering new patterns of gene expression throughout the population. However QS is often much more complex than this simple census-taking behavior. Many QS bacteria produce and detect multiple autoinducers, which generate quorum signal cross talk with each other and with other bacterial species. QS gene regulatory networks respond to a range of physiological and environmental inputs in addition to autoinducer signals. While a host of individual QS systems have been characterized in great molecular and chemical detail, quorum communication raises many fundamental quantitative problems which are increasingly attracting the attention of physical scientists and mathematicians. Key questions include: What kinds of information can a bacterium gather about its environment through QS? What physical principles ultimately constrain the efficacy of diffusion-based communication? How do QS regulatory networks maximize information throughput while minimizing undesirable noise and cross talk? How does QS function in complex, spatially structured environments such as biofilms? Previous books and reviews have focused on the microbiology and biochemistry of QS. With contributions by leading scientists and mathematicians working in the field of physical biology, this volume examines the interplay of diffusion and signaling, collective and coupled dynamics of gene regulation, and spatiotemporal QS phenomena. Chapters will describe experimental studies of QS in natural and engineered or microfabricated bacterial environments, as well as modeling of QS on length scales spanning from the molecular to macroscopic. The book aims to educate physical scientists and quantitative-oriented biologists on the application of physics-based experiment and analysis, together with appropriate modeling, in the understanding and interpretation of the pervasive phenomenon of microbial quorum communication.

Book Description
This book is the bible of bioluminescence and a must-read not only for the students but for those who work in various fields relating to bioluminescence. It summarizes current structural information on all known bioluminescent systems in nature, from well-studied ones to those that have been seldom investigated.This book remains an important source of chemical knowledge on bioluminescence and, since the second edition's publication in 2012, has been revised to include major developments in two systems: earthworm Fridericia and higher fungi whose luciferins have been elucidated and synthesized. These two new luciferins represent an essential addition to seven previously known, with fully rewritten sections covering this new subject matter.

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.

Book Description
The goal of this project was to explore the sensory mechanisms which control the expression of bioluminescence in the marine bacterium Vibrio harveyi. Genetic methods were used to discover the genes which encode functions for the production of extracellular, chemical signals (autoinducers) and for the synthesis of proteins which mediate the response to such signals. A mutant defective in the production of one class of autoinducers was isolated. The gene or genes defective in this mutant were not isolated, but this mutant should be useful for future work to identify specific signaling functions. Another gene, luxT, which is important for transcription of the luxT genes encoding the luminescence enzymes, was cloned and sequenced. Further work to understand its precise role must still be done.

Book Description
Throughout the biological world, bacteria thrive predominantly in surface-attached, matrix-enclosed, multicellular communities or biofilms, as opposed to isolated planktonic cells. This choice of lifestyle is not trivial, as it involves major shifts in the use of genetic information and cellular energy, and has profound consequences for bacterial physiology and survival. Growth within a biofilm can thwart immune function and antibiotic therapy and thereby complicate the treatment of infectious diseases, especially chronic and foreign device-associated infections. Modern studies of many important biofilms have advanced well beyond the descriptive stage, and have begun to provide molecular details of the structural, biochemical, and genetic processes that drive biofilm formation and its dispersion. There is much diversity in the details of biofilm development among various species, but there are also commonalities. In most species, environmental and nutritional conditions greatly influence biofilm development. Similar kinds of adhesive molecules often promote biofilm formation in diverse species. Signaling and regulatory processes that drive biofilm development are often conserved, especially among related bacteria. Knowledge of such processes holds great promise for efforts to control biofilm growth and combat biofilm-associated infections. This volume focuses on the biology of biofilms that affect human disease, although it is by no means comprehensive. It opens with chapters that provide the reader with current perspectives on biofilm development, physiology, environmental, and regulatory effects, the role of quorum sensing, and resistance/phenotypic persistence to antimicrobial agents during biofilm growth.
