Emerging Technologies in Applied and Environmental Microbiology describes various problems and their solutions, that arise in applied and environmental microbiology, using scientific technologies. In ten chapters Emerging Technologies in Applied and Environmental Microbiology summarizes the main omic-based methods, currently used to characterize environmental microorganisms, as well as approaches to analyzing and interpreting the bio information generated by experimentally based studies. Emerging Technologies in Applied and Environmental Microbiology explores the current understanding of bacterial signaling, through examples of communication systems that include, signaling in gram-positive and gram-negative bacteria and discusses how microorganisms interact with each other, with other organisms, and with the environment. Emerging Technologies in Applied and Environmental Microbiology highlights the importance of various emerging technologies, for cleaning up pollution in the environment, caused by human activities. It assesses the potential application of several existing, applied, and environmental microbiological techniques and introduces new emerging technologies through applied aspects.
