Book Description
Actinobacteria are highly diverse prokaryotes that are ubiquitous in soil, freshwater and marine ecosystems. Although various studies have focused on the ecology of this phylum, data are still scant on the diversity, abundance and ecology of actinobacteria endemic to special and extreme environments, such as gut, plant, alkaline saline soil, deep sea sediments, hot springs and other habitats. Actinobacteria are well-known producers of a vast array of secondary metabolites, many of which have useful applications in medicine and agriculture. Furthermore, actinobacteria also have diverse functions in different environments apart from antibiotic production. For example, actinobacteria are reported to contribute to the break-down and recycling of organic compounds. They play a significant role in fixation of nitrogen, improvement plant growth, biodegradation, bioremediation and environmental protection. Therefore, understanding the actinobacterial diversity and distribution in such special environments is important in deciphering the ecological roles of these microorganisms and for biotechnological bioprospecting. Recent advances in cultivation, DNA sequencing technologies and -omics (metagenomics, metaproteomics etc) methods have greatly contributed to the rapid advancement of our understanding of microbial diversity, function and they interactions with environment. Furthermore, comparative genomic studies can provide overall information about actinobacterial speciation, evolution, metabolism and environment adaptation mechanisms. This research topic comprising reviews and original articles highlights the recent advances regarding the unexpectedly diverse/rare group of actinobacteria with special selective isolation methods or culture-independent methods, as well as their biological activities, ecophysiologica function and mechanisms from diverse special and extreme environments.

Book Description
"Actinomycetes are a versatile group of Gram positive bacteria widely distributed in the terrestrial and aquatic environments. The specialty of the actinomycetes is that they have a mycelial appearance unlike most bacteria. This group of bacteria is well known for their ability to produce a range of bioactive molecules, including antibiotics and various kinds of enzymes. As they are known for their ability to produce various antibiotics, the actinomycetes are widely explored by various research groups in search of novel drug molecules. Since the cultivation and maintenance of actinobacteria are not that easy as in the case of other bacteria, they are rather underexplored. With the frequent emergence of multidrug resistant bacteria, which are outpacing the discovery of new antibiotics, there is a renewed interest in actinomycetes from special habitats such as extreme habitats in the marine environment, salt pans, geothermal springs, permanently frozen polar environments etc. Endophytic actinomycetes are also attracting the attention of current researchers in this field. This book titled "A Closer Look at Actinomycetes" is a compilation of articles which deals with interesting topics such as "actinomycetes as microbial drug factories", endophytic fungi from special habitats of Pakistan as well as strategies for exploration of actinomycetes diversity and the taxonomy of actinomycetes should be of great interest to those who are interested in Actinomycetes research. People with interest in general microbiology will also find it an interesting read"--

Book Description
This book places the main actors in environmental microbiology, namely the microorganisms, on center stage. Using the modern approach of 16S ribosomal RNA, the book looks at the taxonomy of marine and freshwater bacteria, fungi, protozoa, algae, viruses, and the smaller aquatic animals such as nematodes and rotifers, as well as at the study of unculturable aquatic microorganisms (metagenomics). The peculiarities of water as an environment for microbial growth, and the influence of aquatic microorganisms on global climate and global recycling of nitrogen and sulphur are also examined. The pollution of water is explored in the context of self-purification of natural waters. Modern municipal water purification and disease transmission through water are discussed. Alternative methods for solid waste disposal are related to the economic capability of a society. Viruses are given special attention. By focusing on the basics, this primer will appeal across a wide range of disciplines.

Book Description
This collection of essays discusses fascinating aspects of the concept that microbes are at the root of all ecosystems. The content is divided into seven parts, the first of those emphasizes that microbes not only were the starting point, but sustain the rest of the biosphere and shows how life evolves through a perpetual struggle for habitats and niches. Part II explains the ways in which microbial life persists in some of the most extreme environments, while Part III presents our understanding of the core aspects of microbial metabolism. Part IV examines the duality of the microbial world, acknowledging that life exists as a balance between certain processes that we perceive as being environmentally supportive and others that seem environmentally destructive. In turn, Part V discusses basic aspects of microbial symbioses, including interactions with other microorganisms, plants and animals. The concept of microbial symbiosis as a driving force in evolution is covered in Part VI. In closing, Part VII explores the adventure of microbiological research, including some reminiscences from and perspectives on the lives and careers of microbe hunters. Given its mixture of science and philosophy, the book will appeal to scientists and advanced students of microbiology, evolution and ecology alike.

Book Description
This book explores the role of in silico deployment in connection with modulation techniques for improving sustainability and competitiveness in the agri-food sector; pharmacokinetics and molecular docking studies of plant-derived natural compounds; and their potential anti-neurodegenerative activity. It also investigates biochemical pathways for bacterial metabolite synthesis, fungal diversity and plant-fungi interaction in plant diseases, methods for predicting disease-resistant candidate genes in plants, and genes-to-metabolites and metabolites-to-genes approaches for predicting biosynthetic pathways in microbes for natural product discovery. The respective chapters elaborate on the use of in situ methods to study biochemical pathways for bacterial metabolite synthesis; tools for plant metabolites in defence; plant secondary metabolites in defence; plant growth metabolites; characterisation of plant metabolites; and identification of plant derived metabolites in the context of plant defence. The book offers an unprecedented resource, highlighting state-of-the-art research work that will greatly benefit researchers and students alike, not only in the field of agriculture but also in many disciplines in the life sciences and plant sciences.

Book Description
This book considers all aspects of bioprospecting in 14 succinct chapters and a forward by David Hawksworth. The organisms addressed include plants, insects, fungi, bacteria and phages. Bioprospecting has never been more relevant and is of renewed interest, because of the extremely worrying rise in novel, resistant pathogenic microorganisms. The practices in pharmaceutical companies have failed to deliver novel antibiotics to control these infections. We need to look for new sources of drugs from the environment on a massive scale as drug discovery is “too important to fail”. Furthermore, the field can add great value to ecosystems in terms of economics, while providing additional reasons for maintaining associated services, such as food provision, benign climate, effective nutrient cycling and cultural practices. Bioprospecting provides another reason why climate change must be reduced in order to preserve relevant environments. Previous bioprospecting projects should be re-visited and established biodiversity centres have a major role. Many different ecosystems exist which contain unique organisms with the potential to supply novel antibiotics, enzymes, food, and cosmetics, or they may simply have aesthetic value. The book stresses the difficulties in obtaining successful products and yet describes why natural products should be investigated over combinatorial chemistry. Personal experience of bioprospecting projects are given significance. Issues such as how to share the benefits equitably with local communities are described and why pharmaceutical companies can be reluctant to be involved. Legal issues are discussed. Finally, there has never been a better time for a new book on bioprospecting, because of the need to preserve ecosystems, and from the emergence of resistant pathogenic microorganisms.
