Book Description
This volume is based on a FEMS Symposium entitled "Bacterial Growth and Lysis: Metabolism and Structure of the Bacterial Sacculus" held at the Monastery of Lluc (Mallorca, Spain) on 5-10 April, 1992. The goals of the symposium were to assess the present state of knowledge on the structure and physiology of the bacterial murein sacculus, and to develop new hypotheses and strategies to promote further development of the field. Consequently, the contributions compiled in this volume include broadly different approaches, from the introduction of new analytical methods to the presentation of provocative models for cell wall growth and division. Structural, biochemical, and genetic aspects are widely covered with special emphasis on the enzymology and regulation of murein hydrolases (autolysins). Comprehensive reviews on bacterial S layers and yeast cell walls are included to stimulate conceptual cross-feeding with these closely related topics. We believe that this book will provide the reader with a useful and up-to-date review of the topic. We would feel deeply rewarded by any positive influence this book may have on the future progress of the field, whereby all the scientific credit for it should be given to the authors of the excellent contributions presented.

Book Description
The Bacteria, Volume IV: The Physiology of Growth focuses on the biochemical phenomena that are expressed at the level of the intact microbial cell and of the growing cell. This book explores the structure, metabolism, and biosynthesis of bacteria. Organized into nine chapters, this volume starts with an overview of the growth requirements, metabolic pathways, individual enzymes, and a variety of other components and functions of the bacterial cell. This text then analyzes the genetic organization of bacteria and explains the nuclear division in bacteria. Other chapters consider the effects of physical environment upon the growth of microorganisms. This book discusses as well the methods for obtaining bacterial cultures by manipulating environmental factors. The final chapter deals with chemotherapeutic drugs, which are valuable tools in the investigation of bacterial organization and function. Bacteriologists, microbiologists, biochemists, microbial physiologists, and cell physiologists interested in the study of bacteria will find this book extremely useful.

Book Description
Bacterial cells are encased in a cell wall, which is required to maintain cell shape and to confer physical strength to the cell. The cell wall allows bacteria to cope with osmotic and environmental challenges and to secure cell integrity during all stages of bacterial growth and propagation, and thus has to be sufficiently rigid. Moreover, to accommodate growth processes, the cell wall at the same time has to be a highly dynamic structure: During cell enlargement, division, and differentiation, bacteria continuously remodel, degrade, and resynthesize their cell wall, but pivotally need to assure cell integrity during these processes. Finally, the cell wall is also adjusted according to both environmental constraints and metabolic requirements. However, how exactly this is achieved is not fully understood. The major structural component of the bacterial cell wall is peptidoglycan (PG), a mesh-like polymer of glycan chains interlinked by short-chain peptides, constituting a net-like macromolecular structure that has historically also termed murein or murein sacculus. Although the basic structure of PG is conserved among bacteria, considerable variations occur regarding cross-bridging, modifications, and attachments. Moreover, different structural arrangements of the cell envelope exist within bacteria: a thin PG layer sandwiched between an inner and outer membrane is present in Gram-negative bacteria, and a thick PG layer decorated with secondary glycopolymers including teichoic acids, is present in Gram-positive bacteria. Furthermore, even more complex envelope structures exist, such as those found in mycobacteria. Crucially, all bacteria possess a multitude of often redundant lytic enzymes, termed “autolysins”, and other cell wall modifying and synthesizing enzymes, allowing to degrade and rebuild the various structures covering the cells. However, how cell wall turnover and cell wall biosynthesis are coordinated during different stages of bacterial growth is currently unclear. The mechanisms that prevent cell lysis during these processes are also unclear. This Research Topic focuses on the dynamics of the bacterial cell wall, its modifications, and structural rearrangements during cell growth and differentiation. It pays particular attention to the turnover of PG, its breakdown and recycling, as well as the regulation of these processes. Other structures, for example, secondary polymers such as teichoic acids, which are dynamically changed during bacterial growth and differentiation, are also covered. In recent years, our view on the bacterial cell envelope has undergone a dramatic change that challenged old models of cell wall structure, biosynthesis, and turnover. This collection of articles aims to contribute to new understandings of bacterial cell wall structure and dynamics.
