Antibiotics are truly miracle drugs. As a class, they are one of the only ones that actually cure disease as opposed to most drugs that only help relieve symptoms or control disease. Since bacteria that cause serious disease in humans are becoming more and more resistant to the antibiotics we have today, and because they will ultimately become resistant to any antibiotic that we use for treatment or for anything else, we need a steady supply of new antibiotics active against any resistant bacteria that arise. However, the antibiotics marketplace is no longer attractive for large pharmaceutical companies, the costs of development are skyrocketing because of ever more stringent requirements by the regulatory agencies, and finding new antibiotics active against resistant strains is getting harder and harder. These forces are all combining to deny us these miracle drugs when we need them the most. I provide a number of possible paths to shelter from this perfect storm.

It is the belief of the editors of this book that the recognition of block copolymers as being amphiphilic molecules and sharing common features with other well-studied amphiphiles will prove beneficial to both the surfactant and the polymer communities. An aim of this book is to bridge the two communities and cross-fertilise the different fields. To this end, leading researchers in the field of amphiphilic block copolymer self-assembly, some having a background in surfactant chemistry, and others with polymer physics roots, have agreed to join forces and contribute to this book.
The book consists of four entities. The first part discusses theoretical considerations behind the block copolymer self-assembly in solution and in the melt. The second part provides case studies of self-assembly in different classes of block copolymers (e.g., polyethers, polyelectrolytes) and in different environments (e.g., in water, in non-aqueous solvents, or in the absence of solvents). The third part presents experimental tools, ranging from static (e.g., small angle neutron scattering) to dynamic (e.g., rheology), which can prove valuable in the characterization of block copolymer self-assemblies. The fourth part offers a sampling of current applications of block copolymers in, e.g., formulations, pharmaceutics, and separations, applications which are based on the unique self-assembly properties of block copolymers.

Recombinant Proteins from Plants is one of the most exciting and fastest developing areas in biology. The latest molecular techniques are being applied to the exploitation of plants as novel expression systems for the p- duction and overproduction of heterologous and native proteins. Transgenic plant technology is currently used in three broad areas: the expression of - combinant proteins to improve crop quality by increasing disease/pest res- tance or increasing tolerance to stress, optimizing plant productivity and yield by the genetic manipulation of metabolic pathways, and the large-scale co- effective production of recombinant proteins for use as specialist industrial or therapeutic biomolecules. The intention of Recombinant Proteins from Plants is to provide c- prehensive and detailed protocols covering all the latest molecular approaches. Because the production oftransgenic plants has become routine in many la- ratories, coverage is also given to some of the more "classical" approaches to the separation, analysis, and characterization of recombinant proteins. The book also includes areas of research that we believe will become increasingly important in the near future: efficient transformation of monocots with Agrobacterium optimizing the stability of recombinant proteins, and a section highlighting the immunotherapeutic potential of plant-expressed proteins.

The bioseparation engineering of today includes downstream process engineering such as waste water, material and gas treatment. Taking this tendency into account, bioseparation engineers gathered in Japan as a special research group under the main theme of "Recovery and Recycle of Resources to Protect the Global Environment."

The scope of this book is based on the conference, and deals not only with recent advances in bioseparation engineering in a narrow sence, but also the environmental engineering which includes waste water treatment and bioremediation. The contributors of this book cover many disciplines such as chemical engineering, analytical chemistry, biochemistry, and microbiology.

"Bioseparation Engineering" will stimulate young engineers and scientists who will develop bioseparation engineering further in the 21st century, and contribute to a world-wide attention to the global environment

Closing the gap between electrochemical engineering science and electrochemical technology, this volume is for all electrochemists and electrochemical engineers, metallurgists, engineers in chemical process, galvanic, metallurgical and electric power industries.

The objectives of this Second Edition of Biotechnology: A Laboratory Course remain unchanged: to create a text that consists of a series of laboratory exercises that integrate molecular biology with protein biochemistry techniques while providing a continuum of experiments. The course begins with basic techniques and culminates in the utilization of previously acquired technical experience and experimental material. Two organisms, "Sacchaomyces cerevisiae" and "Escherichia coli," a single plasmid, and a single enzyme are the experimental material, yet the procedures and principles demonstrated are widely applicable to other systems. This text will serve as an excellent aid in the establishment or instruction of introductory courses in the biological sciences.

This book develops an analysis of the air entrainment processes in free-surface flows. These flows are investigated as homogeneous mixtures with variable density. Several types of air-water free-surface flows are studied: plunging jet flows, open channel flows, and turbulent water jets discharging into air. Experimental observations reported by the author confirm the concept that the air-water mixture behaves as a homogeneous compressible fluid in each case. This book will be of great interest to professionals working in many fields of engineering: chemical, civil, environmental, mechanical, mining, metallurgy, and nuclear.

This volume covers recent developments in the field of immobilization e.g.: new support materials, characterization of support materials, kinetic characterizations, dynamic modelling, bioreactor types, scale up and applications are also given. Applications in the field of medicine, fermentation technology, food technology and environmental technology are described. Guidelines for research with immobilized cells. Based on the scientific sessions a strategy of research and methods for characterization of immobilized cells, especially in view of applications are given.

The goal was to relate basic research to applications and to extract guidelines for characterization of immobilized cells in view of process design and application from the contributions. The manuscripts presented in these proceedings give an extensive and recent overview of the research and applications of immobilized-cell technology.

Aspects of genetic engineering research emphasized in this volume are applications to plants (crop plants and grass, both important for human needs) and new methodologies, such as Tar cloning, which make it much easier to isolate specific regions from complex genomes. Another subject discussed is linear DNA replication of prokaryotes.

Cell separation, which was once limited to merely being a basic technique for fractionating different cell populations, has come a long way in the last two decades. New, advanced and more speci?c and selective techniques have emerged as the demand for isolating a speci?c cell type for various biological applications has increased. Ef?cient and cost-effective techniques for fr- tionation and isolation of target cell types are necessary to provide pure cell populations for diagnostics, biotechnological and biomedical applications. One can see a considerable need, both in biomedical research and in di- nostic medicine, for the speci?c separation of a discrete population of cells from a mixture. For example, in the ?eld of tissue engineering, isolation of stemcellsfromtissuesororgansisofparticularlygreatimportance.Moreover, understanding cell developmental pathways becomes increasingly signi?cant as diagnosis and treatment of diseases turns more to the molecular level. The diagnosis of cell-related diseases requires methods of detection, isolation and theanalysisofindividualcells,regardlessoftheirrelativecontentinthetissue. Since cell-based therapies now turn towards more realistic medical options, developing an effective separation system for large-scale cell separation has becomechallengingresearchgoalforcellbiologistsandbiotechnologists.The ideal technique should provide in a short time a good yield of cells with high puritywhile maintaining cellfunction.Despite the growingneed formethods to separate cells into cell subpopulations, the existing cell-separation te- niques stillhave somelimitations when the desired degree ofperformance on apreparativescaleisrequired.Wewillseemoreresearchfocusinthisdirection in the future. The traditional techniques of micro?ltration, ultra?ltration and ultrac- trifugation, which exploit differences in cell size, shape and density, have remainedtheworkhorsesdespitelowspeci?cityandproblemswithscalingup.

The Carbohydrate Bioengineering Meeting held in Elsinore, Denmark, April 23-26, 1995, gathered 230 scientists, mostly from Europe, with interest in carbohydrate analysis and structure; carbohydrates in medicine and glycopathology; structure, function, application, and protein engineering of carbohydrate active enzymes; oligo- and polysaccharides of industrial interest; and production of carbohydrate containing new materials.

The first chapters address glycoconjugates as modulatory and recognition molecules, structure determination using NMR and mass spectrometry, and microdialysis-chip enzyme-based sensors. Active site mutations coupled with crystal structures and synthetic substrate analogue interactions as well as new three-dimensional structures and binding domains for biotechnological applications are included in the chapters. Carbohydrate active enzymes turned out to be a predominant topic.

The rapid development in glycobiology and glycotechnology has resulted in an enormous increase in our knowledge on the structure conversion, and application of carbohydrates in industry and medicine.

This Volume provides protocols for the biochemical analysis of hydrocarbon- and lipid-relevant products, cell components and activities of microbes that interact with hydrophobic compounds. They include methods for the extraction, purification and characterisation of surface tension-reducing bioemulsifiers and biosurfactants that increase the surface area and hence bioavailability of hydrophobic substrates. Protocols for the isolation and biochemical analysis of lipids and polyhydroxyalkanoates, food storage products made during nutrient abundance that represent important biotechnological products, are presented. The extraction of membrane lipid rafts, sub-organelles that fulfil important functional roles for the cell membrane, and the isolation and characterisation of membrane phospholipid biomarkers, are also described. The purification and characterisation of integral membrane hydrocarbon-oxidising enzymes are addressed. Lastly, two generic methods for the genetic analysis of catabolic pathways and analysis of ligand binding are presented. Hydrocarbon and Lipid Microbiology ProtocolsThere are tens of thousands of structurally different hydrocarbons, hydrocarbon derivatives and lipids, and a wide array of these molecules are required for cells to function. The global hydrocarbon cycle, which is largely driven by microorganisms, has a major impact on our environment and climate. Microbes are responsible for cleaning up the environmental pollution caused by the exploitation of hydrocarbon reservoirs and will also be pivotal in reducing our reliance on fossil fuels by providing biofuels, plastics and industrial chemicals. Gaining an understanding of the relevant functions of the wide range of microbes that produce, consume and modify hydrocarbons and related compounds will be key to responding to these challenges. This comprehensive collection of current and emerging protocols will facilitate acquisition of this understanding and exploitation of useful activities of such microbes.

Woody Species: Coffee, Eucalyptus, guazuma, horse-chestnut, neem, olive, poplar, oak, Prunus, Ribes, rose.IV. Australian Species.Initially, cryopreservation was driven by the concern for loss of diversity of crops essential for continued improvement of the many plants used for food, health, and shelter. The interest has been expanded by conservationists and their concerns for retaining the diversity of natural populations.

Solvent Extraction in Biotechnology deals with the reco- very and purification of primary and secondary metabolites by solvent extraction. In the first part the reaction engineering principles: definitions, thermodynamic fundamentals, and system models, the kinetics of mass transfer between two phases without and with chemical reaction as well as extraction equipment, which are important for downstream processing in biotechnology, are considered in detail. The special part of the book describes the recovery of low-molecular metabolites: alcohols, acids and antibiotics with organic solvents, carrier-modifier-solvent systems, supercritical gases as well as with liquid membrane techniques. Several practical examples are given for the recovery of different metabolites as well as for the calculation of the extraction processes necessary for equipment design. Besides solvent extraction, novel separation techniques with liquid membrane, microemulsion and reversed micelles are also presented. This book will introduce the biochemical engineer and process engineer to the recovery of products from complex cultivation broths by modern techniques of solvent extraction and help them with process design.

This Volume presents a comprehensive series of generic protocols for the genetic and genomic analysis of prokaryotic isolates. Genetic methods for functional analyses employ the latest cloning vectors, gene fusion methods and transposon mutagenesis systems, as well as systems for introducing protease-cleavage sequences into permissive sites in proteins under investigation. Genomic methods described include protocols for transcriptomics, shotgun proteomics, interactomics, metabolic profiling, and lipidomics. Bioinformatic tools for genome annotation, transcriptome display and the integration of transcriptomic data into genome-scale metabolic reconstructions are described. Protocols for 13C-based metabolic flux determinations and analysis of the hierarchical and metabolic regulation of fluxes through pathways are included. The Volume thus enables investigators to functionally analyse an isolate over the entire cellular range spanning the gene, the genome, the transcript repertoire, the proteome, the interactome, the metabolic network with its nodes and their regulatory hierarchies, and the metabolic fluxes and their physiological controls. Hydrocarbon and Lipid Microbiology Protocols There are tens of thousands of structurally different hydrocarbons, hydrocarbon derivatives and lipids, and a wide array of these molecules are required for cells to function. The global hydrocarbon cycle, which is largely driven by microorganisms, has a major impact on our environment and climate. Microbes are responsible for cleaning up the environmental pollution caused by the exploitation of hydrocarbon reservoirs and will also be pivotal in reducing our reliance on fossil fuels by providing biofuels, plastics and industrial chemicals. Gaining an understanding of the relevant functions of the wide range of microbes that produce, consume and modify hydrocarbons and related compounds will be key to responding to these challenges. This comprehensive collection of current and emerging protocols will facilitate acquisition of this understanding and exploitation of useful activities of such microbes.

The quantity and composition of aroma and avour compounds in foods and food products exert a marked in uence on the consumer acceptance and, consequently, on the commercial value of the products. It has been established many times that one of the main properties employed for the evaluation of the product quality is the avour, that is, an adequate avour composition considerably enhances the m- ketability. Traditional analytical methods are generally unsuitable for the accurate determination of the quantity of this class of compounds. Moreover, they do not contain any useful information on the concentration of the individual substances and they are not suitable for their identi cation. As the stability of the aroma compounds and fragrances against hydrolysis, oxidation and other environmental and tech- logical conditions shows marked differences, the exact determination of the avour composition of a food or food product may help for the prediction of the she- life of products and the assessment of the in uence of technological steps on the aroma compounds resulting in more consumer-friendly processing methods. Furthermore, the qualitative determination and identi cation of these substances may contribute to the establishment of the provenance of the product facilitating the authenticity test. Because of the considerable commercial importance of avour composition, much effort has been devoted to the development of methods suitable for the separation and quantitative determination of avour compounds and f- grancesinfoodsandinotherindustrialproducts.
