Book Description
The search for new producers of biologically active substances (BAS) against human and animal diseases continues to be an important task in biology and medicine. Experimental work must be carried out well in advance of need because it takes an average of ten years to develop a new medication, as well as additional time to put it on the market. Study of the Protozoa forms a special branch of biology - protozoology. The traditional fields of protozoology are taxonomy, phylogeny, morphology, cytology, evolution, ecology and host parasite-interactions. The Protozoa is the only taxon among the microscopic organisms, which has not been persistently studied as a source of BAS. This book then is the result of the research on the project: "Biologically active substances of the Mastigophora (Flagellates)". The research was carried out at the Laboratory of Antibiotics, Department of Microbiology, Biological Faculty of Moscow State University. Articles of other authors on the matter have been considered as the important part of this reference book. The goal of the reference book is to elucidate scientific approaches, which lead to obtaining biologically active substances from cultures of protozoa; the book reviews the historical background in connection with contemporary development of the field. N.N. Sukhareva ACKNOWLEDGMENTS The research was performed in fruitful cooperation with my research associates (V. Urinyuk, T. Titiova, L. Udalova, R. Zeleneva, V. Brusovanik, M. Zaretskaya), postgraduate students (N. Kalenik, M. Chuenkova, V. Vasilevskaya, V. Khorokhorina), my colleagues at Moscow State University (Yu. Kozlov and I.

Book Description
This book emphasises the important role that protozoa play in many natural ecosystems. To shed new light on their individual adaptive skills, the respective chapters examine the ecology and functional biology of this diverse group of eukaryotic microbes. Protozoa are well-established model organisms that exemplify many general problems in population ecology and community ecology, as well as evolutionary biology. Their particular characteristics, like large population sizes, life cycles and motile sensory behaviour, have a profound impact on their survival, distribution, and interaction with other species. Thus, readers will also be introduced to protozoan habitats in a broad range of environments. Even though this group of unicellular organisms is highly diverse, the authors focus on shared ecological patterns. Students and scientists working in the areas of eukaryotic microbiology and ecology will appreciate this updated and revised 2nd Edition as a valuable reference guide to the “lifestyles” of protozoa.

Book Description
Protozoa are active components of the soil microfauna. For example, they may stimulate bacterial metabolism and some fungal metabolites can lyse protozoa. They may be predators of bacteria and hence have a role in biological control. Their presence in groundwaters can be used as an indicator of pollution, while they are also being used to treat sewage in the activated-sludge and reed-bed processes. They are believed to be major secondary decomposers in soil and increased knowledge about these microorganisms is important to sustain soil fertility and food production. This book is the first in English for 65 years devoted entirely to soil protozoology. It is written by experienced microbiologists and should be of interest to protozoologists, other microbiologists, and soil scientists.

Book Description
This book presents an updated discussion of the chemical composition and biological properties of the main bee products. Specific attention is focused on the beneficial biological activities of bee products in human health. Honey, royal jelly, propolis, bee pollen and bee venom are used as nutriment and in traditional medicine. Their composition is rather variable and depends on the floral source and external factors, such as seasonal, environmental conditions and processing. Bee products are rich in several essential nutrients and non essential nutrients, as sugars, minerals, proteins, free amino acids, vitamins, enzymes and polyphenols, that seem to be closely related to their biological functions. The effects of these products in nutrition, aging and age-related diseases, cancer, neurodegenerative diseases and pathogen infections are discussed.

Book Description
Protists are by far the most diverse and abundant eukaryotes in soils. Nevertheless, very little is known about individual representatives, the diversity and community composition and ecological functioning of these important organisms. For instance, soil protists are commonly lumped into a single functional unit, i.e. bacterivores. This work tackles missing knowledge gaps on soil protists and common misconceptions using multi-methodological approaches including cultivation, microcosm experiments and environmental sequencing. In a first part, several new species and genera of amoeboid protists are described showing their immense unknown diversity. In the second part, the enormous complexity of soil protists communities is highlighted using cultivation- and sequence-based approaches. In the third part, the present of diverse mycophagous and nematophagous protists are shown in functional studies on cultivated taxa and their environmental importance supported by sequence-based approaches. This work is just a start for a promising future of soil Protistology that is likely to find other important roles of these diverse organisms.
