Format: PDF / Kindle (mobi) / ePub
The authoritative #1 textbook for introductory majors microbiology, Brock Biology of Microorganisms continues to set the standard for impeccable scholarship, accuracy, and outstanding illustrations and photos. This book for biology, microbiology, and other science majors balances cutting edge research with the concepts essential for understanding the field of microbiology.
In addition to a new co-author, David Stahl, who brings coverage of cutting edge microbial ecology research and symbiosis to a brand new chapter (Chapter 25), a completely revised overview chapter on Immunology (Chapter 28), a new "Big Ideas" section at the end of each chapter, and a wealth of new photos and art make the Thirteenth Edition better than ever. Brock Biology of Microorganisms speaks to today’s students while maintaining the depth and precision science majors need.
optima of 20–40 8C are called psychrotolerant. Psychrophiles are found in environments that are constantly cold and may be rapidly killed by warming, even to as little as 20 8C. For this reason, their laboratory study requires that great care be taken to ensure that they never warm up during sampling, transport to the laboratory, isolation, or other manipulations. In open ocean waters, where temperatures remain constant at about 3 8C, various cold-active Bacteria and Archaea are present, although
piles and silage can also reach temperatures of 70 8C. However, the most extensive and extreme high-temperature environments in nature are associated with volcanic phenomena. These include, in particular, hot springs. Many hot springs have temperatures at or near boiling, and steam vents (fumaroles) may reach 150–500 8C. Hydrothermal vents in the bottom of the ocean can have temperatures of 350 8C or greater ( Section 23.12). Hot springs exist throughout the world, but they are especially
systems of animals or the leaves of plants. What is the science of microbiology all about? Microbiology is about microbial cells and how they work, especially the bacteria, a very large group of very small cells (Figure 1.1) that, collectively, have enormous basic and practical importance. Microbiology is about diversity and evolution of microbial cells, about how different kinds of microorganisms arose and why. It is also about what microorganisms do in the world at large, in soils and waters,
animals. These include many of the diseases associated with bacteria that live only within cells, such as the rickettsias and chlamydias, and diseases caused by some viruses and protozoan parasites. So for most of these diseases cause and effect cannot be unequivocally proven. However, the clinical and epidemiological (disease tracking) evidence for virtually every infectious disease of humans lends all but certain proof of the speciﬁc cause of the disease. Thus, although Koch’s postulates remain
