Book Description :

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.

Book Description :

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.

Book Description :

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.

Book Description :

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?

Book Description :

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.

Book Description :

Lipids are very important both as components of human nutrition and in applications such as the chemical, cosmetics and food industries. At present the world oil supply depends on conventional sources and changes in the political and economical map of the world may mean consumer demand will surpass supplies. In developed nations consumer preferences due to nutrition and health factors have also created a need to produce new types of oil. Many nations lack the power to purchase fats ,and oil due to shortages in hard currency. These nations have a vast number of plants that can be developed and used in extracting oil for home use and for sale as cash crops. Also, a vast amount of waste from food processing, such as tomatoes, peaches, plums and grapes, can be utilized to extract valuable amounts of usable oil. Biotechnology, genetic engineering, enzyme tech nologies and new processes are all being utilized in lipids research to develop new and modified types of oil for different applications; such developments include the high oleic acid, sunflower and rapeseed oils. The development of cocoa butter substitute is another example. This highly practical book reviews the methods of improving oil charac teristics from existing sources, and the technology and economics of developing under-utilized sources. It is written for lipid chemists, chemical engineers, food technologists, cosmetologists and nutritionists. Graduate and undergraduate students will find value in the data. B.S.K.

A comprehensive review of the yeast cell envelope has not appeared previously and therefore this book is timely. The title of this volume was chosen to reflect the three major areas of contribution to our current understanding of the cell envelope, but we have not attempted to group chapters into subdivisions. The approach was to describe phenomena, to review the literature and to illuminate outstanding problems. It was also attempted to generate working hypotheses which may stimulate further studies. The some of these ideas be of germinal value is of more concern to us than that all of the hypotheses should stand the test of further experimentation.

Book Description :

Basidiomycetous yeast play a key role in the phylosphere ecology. These organisms have adapted a series of strategies that have allowed them to colonize and thrive in leaf surfaces and other plant surface interaction environments. In such environments carbon and other key nutrients including nitrogen can be abundant at times, or scarce or almost absent at other times. One of the traits with competitive advantages is the production of different lipid classes, in the form of accumulation of neutral lipids, notably triacylglycerols, or secretion of biosurfactants, notably glycolipids. These biological strategies of basidiomycetous yeasts enabling them to thrive in a phylosphere ecology can have important implications in today's biotechnology industry. The yeast living in the surface of leaves can instruct the biotechnology research community that in order to thrive in a challenging environment, it is necessary to create multiple products targeted to satisfy multiple necessities at the same time, in a systematic and synchronized way. Therefore, the present work takes this biological principle from evolution and provides the framework to establish a translational strategy to exploit the potential of basidiomycetous yeast as key component of a multiple co-product biorefinery system. The results of this research provide insights to the broader scientific community on how to identify, culture and obtain multiple high value co-products and a proof of principle for a next generation approach in biotechnology. These goals were accomplished by: first, a literature review of the mechanisms of lipid production in the different microbial kingdoms and the metabolic tools to understand how microbes, and in particular basidiomycetous yeast, synthesize, accumulate and secrete lipids. The next chapter explores the Sporidiobolales order to demonstrate the richness and diversity within this order of basidiomycetous yeast in terms of intracellular TG production (Chapter II). The next chapter takes a parallel approach to establish extracellular lipid production in the form of polyol esters of fatty acids (Chapter III). The next chapter illustrates the implementation of a multiple co-product model using selected strains from chapters II and III to produce industrially relevant quantities of intracellular TG and PEFA. Finally, the concluding Chapter provides a translational strategy to realize the potential use of these strains scientifically and the future steps required to bring this knowledge to practice as a production platform to biotechnology.
