Actinomycetes in Marine and Extreme Environments


Book Description

The discovery and development of antibiotics has been one of the most significant advances in medicine. In a golden era lasting from the 1940s to the late 1960s, antibiotic research provided mankind with a wide range of structurally diverse and effective agents for the treatment of microbial infections. Since then, actinomycetes, most notably members of the genus Streptomyces, have uninterruptedly proved to be a particularly rich source of antibiotics and other therapeutic and biotechnologically important compounds. This book brings together expert actinomycetologists to communicate the importance of finding novel antibiotic producing actinomycetes in extreme and marine environments in the light of molecular advances.

A Closer Look at Actinomycetes


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"--




Developments in Sustainable Chemical and Bioprocess Technology


Book Description

Environmental sustainability and development is of critical importance. Technological advances in the production of new energy sources are making their way into our lives in more and more depth every day. However, there is an urgent need to address the technological challenges and advancement of the various chemical and bio-processes to maintain the dynamic sustainability of our energy needs. Toward that end, an attempt is being made to look at recent advances, key issues still faced and where possible, offer suggestions on alternative technologies to optimize sustainable processes. Still considered a new area of science, energy sources themselves are still being 'discovered'...meaning, what is financially viable in the current marketplace is changing. For example, energy from plants has not been financially viable in the past because of the high cost of growing, harvesting, breaking down cell walls, disposal of waste products, etc. Materials used to derive energy from sustainable resources is changing, making previously high-cost processes more efficient. It is crucial that the industry as a while works in tandem to develop crops that new technological advances make financially feasible. This book will cover recent advances in the chemicals, bioprocesses and other materials used in growing and extracting energy from sustainable products. Membrane/cell wall digestion issues will also be covered as well as recovering mamixal amounts of energy from sources to limit waste. Finally a section on safety and control will be presented with has been poorly covered in other publications. ​




Extremophiles in Deep-Sea Environments


Book Description

Many organisms in deep-sea environments are extremophiles thriving in extreme conditions: high pressure, high or low temperature, or high concentrations of inorganic compounds. This book presents the microbiology of extremophiles living in the deep sea and describes the isolation, cultivation, and taxonomic identification of microorganisms retrieved from the Mariana Trench, the world's deepest point. Also explained are techniques for recovering pressure-loving bacteria, the barophiles (piezophiles), and for whole genome analysis of Bacillus halodurans C-125. Physiological analysis of the pressure effect in Saccharomyces cerevisiae and Escherichia coli is used to answer the question of how deep-sea organisms survive under high hydrostatic pressure. These research results are useful in both basic science and industrial applications. Readers discover a new microbial world in the ocean depths, with state-of-the-science information on extremophiles.




Biofertilizers


Book Description

Great attention has been paid to reduce the use of conventional chemical fertilizers harming living beings through food chain supplements from the soil environment. Therefore, it is necessary to develop alternative sustainable fertilizers to enhance soil sustainability and agriculture productivity. Biofertilizers are the substance that contains microorganisms (bacteria, algae, and fungi) living or latent cells that can enrich the soil quality with nitrogen, phosphorous, potassium, organic matter, etc. They are a cost-effective, biodegradable, and renewable source of plant nutrients/supplements to improve the soil-health properties. Biofertilizers emerge as an attractive alternative to chemical fertilizers, and as a promising cost-effective technology for eco-friendly agriculture and a sustainable environment that holds microorganisms which enhance the soil nutrients' solubility leading a raise in its fertility, stimulates crop growth and healthy food safety. This book provides in-depth knowledge about history and fundamentals to advances biofertilizers, including latest reviews, challenges, and future perspectives. It covers fabrication approaches, and various types of biofertilizers and their applications in agriculture, environment, forestry and industrial sectors. Also, organic farming, quality control, quality assurance, food safety and case-studies of biofertilizers are briefly discussed. Biofertilizers' physical properties, affecting factors, impact, and industry profiles in the market are well addressed. This book is an essential guide for farmers, agrochemists, environmental engineers, scientists, students, and faculty who would like to understand the science behind the sustainable fertilizers, soil chemistry and agroecology.
