Extracellular Glycolipids of Yeasts: Biodiversity, Biochemistry, and Prospects provides a comprehensive view of the biochemistry, biological activity, and practical application of extracellular glycolipids of yeast. This book brings much-needed clarity to the complex topic of glycolipids and streamlines the rather confusing terminology used for glycolipids. It also provides a wealth of modern data on their composition, structure and properties, biosynthetic pathways, methods of isolation and identification, antifungal activity, and mechanisms of action. Studies of extracellular glycolipids of yeast now draw the attention of researchers in life science and biotechnology due to numerous recently revealed biological properties of these compounds. These compounds are scientifically and practically promising in medicine and agriculture due to their biosurfactant and fungicidal properties, as well as a number of other biological activities. Extracellular Glycolipids of Yeasts gives researchers studying biochemistry of microorganisms and related biologically active compounds a much-needed guide to the basic data that will aid in these increasingly generative pursuits. Provides a clear overview of the basic data on yeast biosurfactants using a simple survey-style approach Delivers comprehensive view of biochemistry, biological activity, and practical application of yeasts to aid in their scientific and practical use Clarifies and simplifies the complex topic of glycolipids, and its often-confusing terminology

A Guide to the World of the Yeasts J. F. T. Spencer and D. M. Spencert As the well-known authority on yeasts, the late Professor Rose, frequently pointed out, it is impossible for one person to present, in a single volume, the details of the life, composiotion, habitats, relationships, and actual and potential uses to man kind of the 500 (at last count) known species of yeasts. This book confirms the truth of this statement. However, our aim is actually more modest than that, and this book is an attempt to introduce the general reader, and possibly some inter ested specialists, to the lives of the yeasts in their natural and more artificial habitats, their use by human beings, and to give some idea of the wonderfully complex activities within the yeast cell, the characteristics of the metabolism and molecular biology of yeasts, and the applications of these characteristics to life in the present-dayworld ofhuman existence. The book proceeds from a brief chapter on what is and is not known of the origins and early history of the yeasts, through a description of their classification, relationships, habitats and general life style, their external morphology and internal structures and mechanisms within their cells, the regulatory mechanisms controlling processes such as signal transmis sion, mating, cell fusion, and many others.

Glycolipids are carbohydrate-attached lipids. Their role is to provide energy and also serve as markers for cellular recognition. They occur where a carbohydrate chain is associated with phospholipids on the exoplasmic surface of the cell membrane. The carbohydrates are found on the outer surface of all eukaryotic cell membranes. They extend from the phospholipid bilayer into the aqueous environment outside the cell where it acts as a recognition site for specific chemicals as well as helping to maintain the stability of the membrane and attaching cells to one another to form tissues. This new book focuses on recent research results from around the world.

The early history and development of the field of glycolipids was concerned mainly with the predominant glycolipids found in higher animal tissues, namely the glycosphingolipids, as has been extensively documented by J. N. Kanfer and S. Hakomori in Volume 3 of this series. The major glycolipids in organisms of the plant kingdom, however, such as bacteria, yeasts and fungi, algae, and higher plants, are glycoglycerolipids, although glycosphingolipids are also present as minor components in these organisms, except for bacteria. It is of interest that one of the pioneers in glycosphingolipid research, Herbert E. Carter, also pioneered the discovery and structural elucidation of the plant galactosyldiacylglycerols. This class of glycolipids is present in chlo roplast membranes and must surely be one of the most ubiquitous and abun dant natural substances in the world, thereby deserving the attention of lipid biochemists. It is therefore surprising to learn that in contrast to the glycosphingolipids, which were discovered in the 1870s, glycoglycerolipids were not discovered until the 1950s. Since that time investigations of the structure and distribution of these glycolipids have proceeded at an exponen tially increasing rate, and much information is now available for representa tives of many genera of bacteria, yeasts, algae, and higher plants. Glycoglyce rolipids have also been identified in animal cells, particularly in the brain, testes, and sperm.

In the last few decades more and more yeast habitats have been explored, spanning cold climates to tropical regions and dry deserts to rainforests. As a result, a large body of ecological data has been accumulated and the number of known yeast species has increased rapidly. This book provides an overview of the biodiversity of yeasts in different habitats. Recent advances achieved by the application of molecular biological methods in the field of yeast taxonomy and ecology are also incorporated in the book. Wherever possible, the interaction between yeasts and the surrounding environment is discussed.

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?

Life on the planet depends on microbial activity. The recycling of carbon, nitrogen, sulphur, oxygen, phosphate and all the other elements that constitute living matter are continuously in flux: microorganisms participate in key steps in these processes and without them life would cease within a few short years. The comparatively recent advent of man-made chemicals has now challenged the environment: where degradation does not occur, accumulation must perforce take place. Surprisingly though, even the most recalcitrant of molecules are gradually broken down and very few materials are truly impervious to microbial attack. Microorganisms, by their rapid growth rates, have the most rapid turn-over of their DNA of all living cells. Consequently they can evolve altered genes and therefore produce novel enzymes for handling "foreign" compounds - the xenobiotics - in a manner not seen with such effect in other organisms. Evolution, with the production of micro-organisms able to degrade molecules hitherto intractable to breakdown, is therefore a continuing event. Now, through the agency of genetic manipulation, it is possible to accelerate this process of natural evolution in a very directed manner. The time-scale before a new microorganism emerges that can utilize a recalcitrant molecule has now been considerably shortened by the application of well-understood genetic principles into microbiology. However, before these principles can be successfully used, it is essential that we understand the mechanism by which molecules are degraded, otherwise we shall not know where best to direct these efforts.
