Описание: Soft drinks with pHs lower than 4. 0 are subjected to minimum pasteuri- tion at 65 °C for 10 min as required by the Japanese Food Sanitation Law. Not only pathogenic bacteria but most spore-forming bacteria are unable to grow at this low pH condition, and thus reports of microbial spoilage in pasteurized acidic soft drinks are rare. Since 1982, when the spoilage of aseptically packed apple juice was - tributed to a new type of acidophilic spore-forming bacteria in Germany, a succession of similar complaints regarding other fruit juice concentrates and their products has been received. In the beginning, the bacteria were classified in the genus Bacillus, but later, in 1992, the new genus Ali- clobacillus was proposed owing to their characteristic cellular membranes containing omega-alicyclic fatty acids. A group of Alicyclobacillus strains, responsible for the tainting of fruit juices, was then described as A. a- doterrestris in 1999. They are acidophilic and grow preferably at around pH 4. 0. They are thermophilic and grow better at temperatures above 40 °C. This indicates that we might have been missing them by our or- nary methods of bacterial detection at pH 7. 0 and 35 °C. Their spores are not inactivated by the pasteurizing conditions generally applied to juice concentrates and juice-containing beverages. Above all, because the bac- ria do not produce gas, consumers do not see any sign of spoilage until they open the product and notice its unpleasant taint.

Описание: Plant growth promoting microorganisms (PGPM) have gained acceptance and importance due to their dual benefits of promoting plant growth in addition to managing plant pests and diseases and are extensively used as microbial inoculants in improving agricultural productivity. Use of PGPM mixtures and their integration with other means, like host resistance and chemicals, has proven to be more useful in management of several disease problems. Successful greenhouse and field demonstrations have been done using PGPM for growth promotion and resistance induction in various crops, against a broad spectrum of pathogens. Practical use of PGPM-based products has advanced and many formulations are made available in commercial scale, and more are currently under development. Further, novel formulation technologies have been formulated. Microorganisms constitute the major players in the rhizosphere and their composition and biomass significantly alters the plants response to the environment. Composition and interaction of rhizomicroflora with its surroundings highly influences plant health and productivity. Such beneficial rhizo-ecosystems engineering and manipulation of the rhizosphere to exploit or enhance this innate genetic potential, which will most probably play a key role in the future development of sustainable agricultural processes, is also reviewed. In recent years, a substantial amount of work has been done in the area of PGPM and voluminous literature is available. This book presents a methodical, comprehensive and latest research survey in this area. An overview of the scale and impact of PGPM in plant growth promotion and management of crop diseases, focusing attention on details most relevant to the development and application of biological control strategies involving various microbial strains is discussed. Problems and prospects of commercialisation, advantages and disadvantages of their use and their potential for integrated pest management are also outlined. Most of the available books either refer to the subject of plant growth promoting fungi or plant growth promoting bacteria, however, this comprehensive book includes research pertaining to all beneficial microorganisms that are plant growth promoting in nature. Moreover, this is a rapidly developing field of research and has global impact. Therefore, keeping in pace with the latest developments in this area is totally necessary, and this book will be a latest and up-to-date compilation of the research from different parts of the world.

Описание: Biotechnology of extremophiles - the applied science field that seeks to employ extremophilic organisms in order to discover in particular novel and unique useful biocompounds and genetic systems. This book aims to give a broad overview on the potential usage of extremophiles in biotechnology (e.g. industry, medicine, food, cosmetics, environmental clean-up, energy and fuel, geo-sciences), including the production of compounds (e.g. enzymes, compatible solutes) or the degradation of compounds such as xenobiotics etc. The book contains reviews on various recent discoveries, applications and visions of a large variety of extremophiles - focusing not only on prokaryotes, but also on eukaryotes as well as viruses.
Описание: This book will highlight advanced techniques that were recently used for studying microorganisms in extreme environments. Recent technological leaps in the study of microorganisms in the environment now make it possible to comprehensively study microbes in the environment. Extreme environments could benefit from the application of these techniques, but many challenges such as low biomass, low activity and slow growth has prevented their wide adoption. This book will review recent application of state-of-the-art techniques in extreme environments, helping researcher and graduate students get a better knowledge of the tools available.
