Book Description
Actinobacteria (Actinomycetes) represent one of the largest and most diverse phyla among Bacteria. The remarkable diversity is displayed by various lifestyles, distinct morphologies, a wide spectrum of physiological and metabolic activities, as well as genetics. Interestingly, most Actinobacteria have a high GC-content (ranging from 51% to >70%) and belong to Gram-positive or Gram-variable type microbes. Many species are well known for large genomes which may be of linear style as in case of rhodococci or circular. Many of those harbor linear megaplasmids as a kind of genetic storage device. Frequently gene redundancy is reported and in most cases the evolutionary history or a functional role remains enigmatic. Nevertheless these large genomes and megaplasmids provide access to a number of potential (homologous) biocatalysts which await elucidation. Actinobacteria are well known for their biotechnological potential which is exemplarily described for amino acid producing Corynebacteria, secondary metabolite producing Streptomyces, pathogenic targets as Nocardia and Mycobacteria, carotenoid building Micrococcus strains, acid fermenting Propionibacteria, health and food related Bifidobacterium strains, rubber degrading Gordonia species, and organic pollutant degrading rhodococci among others. In many cases individual pathways or enzymes can be modified or recombinantly employed for biocatalysis. Even some genetic tools to work directly in those microbes have been successfully used as for example in Corynebacterium or in Rhodococcus species. During the last decade more and more genomes have been sequenced and made available for data mining and become accessible by state of the art genomic manipulation methods as minimal genomes, knock-out or artificial evolution. With respect to this large and ancient phylum many questions can be asked either from a scientific or industrial point of view. In order to provide some crystallization points we like to raise some examples as follows. How small can be an actinobacterial genome? What is the driving force to comprise large and repetitive genomes/megaplasmids? What is needed to generate an actinobacterial power house for industry? Can we annotate novel biocatalysts from scratch and improve functional annotation? What are common and different features with respect to other bacteria and/or fungi? How many novel antibiotics are hidden among Actinobacteria? Is there more potential among extremophile members or are they only specialized? Here especially the production of natural compounds is of high interest.

Book Description
Deliberately breaking with the classical biology-centered description of marine organisms and their products, this reference emphasizes microbial technology over basic biology, setting it apart from its predecessors. As such, it systematically covers the technology behind high-value compounds for use as pharmaceuticals, nutraceuticals or cosmetics, from prospecting to production issues. Following a definition of the field, the book goes on to address all industrially important aspects of marine microbial biotechnology. The first main part contains a description of the major production organisms, from archaebacteria to cyanobacteria to algae and symbionts, including their genetic engineering. The remaining four parts look at commercially important compounds produced by these microorganisms together with their applications. Throughout, the emphasis is on technological considerations, and the future potential of these organisms or compound classes is discussed. A valuable and forward-looking resource for innovative biotechnologists in industry as well as in academia.

Book Description
Corynebacterium glutamicum is most widely known for its role in the industrial production of L-glutamate and L-lysine and as a platform organism for the production of a variety of fine chemicals, biofuels, and polymers. The organism's accessibility to genetic manipulation has resulted in a wealth of data on its metabolism and regulatory networks; this in turn makes C. glutamicum the model organism of choice in white biotechnology. A key development in recent years has been the engineering of C. glutamicum to utilize a broader spectrum of carbon sources (e.g. glycerol, galactose, and pentose sugars), in addition to the traditional hexoses. Given its unique ability to co-utilize mixed carbon sources, C. glutamicum could be used for the clean-up of wastes from agricultural or other industries, simultaneously producing useful compounds such as L-lysine or putrescine. This book provides a comprehensive overview of current knowledge and research on C. glutamicum systems biology and biotechnological applications. Written by a team of prominent scientists, the topics covered include: proteomics * flux analysis technology for metabolic analysis * metabolic engineering for alternative carbon source utilization * manipulation of nitrogen metabolism * transport, degradation, and assimilation of aromatic compounds and their regulation * engineering for production of organic acids and alcohols * microbial factory for the production of polyesters * biotechnological application under oxygen deprivation * the secretory production of heterologous proteins * genetically-encoded biosensors.

Book Description
The Prokaryotes is a comprehensive, multi-authored, peer reviewed reference work on Bacteria and Achaea. This fourth edition of The Prokaryotes is organized to cover all taxonomic diversity, using the family level to delineate chapters. Different from other resources, this new Springer product includes not only taxonomy, but also prokaryotic biology and technology of taxa in a broad context. Technological aspects highlight the usefulness of prokaryotes in processes and products, including biocontrol agents and as genetics tools. The content of the expanded fourth edition is divided into two parts: Part 1 contains review chapters dealing with the most important general concepts in molecular, applied and general prokaryote biology; Part 2 describes the known properties of specific taxonomic groups. Two completely new sections have been added to Part 1: bacterial communities and human bacteriology. The bacterial communities section reflects the growing realization that studies on pure cultures of bacteria have led to an incomplete picture of the microbial world for two fundamental reasons: the vast majority of bacteria in soil, water and associated with biological tissues are currently not culturable, and that an understanding of microbial ecology requires knowledge on how different bacterial species interact with each other in their natural environment. The new section on human microbiology deals with bacteria associated with healthy humans and bacterial pathogenesis. Each of the major human diseases caused by bacteria is reviewed, from identifying the pathogens by classical clinical and non-culturing techniques to the biochemical mechanisms of the disease process. The 4th edition of The Prokaryotes is the most complete resource on the biology of prokaryotes. The following volumes are published consecutively within the 4th Edition: Prokaryotic Biology and Symbiotic Associations Prokaryotic Communities and Ecophysiology Prokaryotic Physiology and Biochemistry Applied Bacteriology and Biotechnology Human Microbiology Actinobacteria Firmicutes Alphaproteobacteria and Betaproteobacteria Gammaproteobacteria Deltaproteobacteria and Epsilonproteobacteria Other Major Lineages of Bacteria and the Archaea
