About the book

Extremophilic microbes are microorganisms that can grow under a remarkable range of extreme environments such as glacial deserts, hot springs, ocean floors, hypersalted environments, rocks of the Earth's mantle. These include acidophiles, alkaliphiles, halophiles, barophiles, (hyper) thermophiles, and psychrophiles. These hostile environments shelter the rich biodiversity of extremophiles which could belong to one of the three domains of life (Bacteria, Archaea, and Eukaryotes). These microbes have evolved several mechanisms to ensure genomic integrity, cell division, and energy conservation in extreme conditions. They present a wide and versatile metabolic and enzymatic diversity coupled with extraordinary physiological capacities in rich extreme environments. These enzymes and metabolites have been exploited to develop clean and sustainable industrial processes. Antibiotics, compatible solutes, and other compounds obtainable from these microbes are also finding a variety of uses. Recently, several investigations have been started to study the phylogenetic relationship between extremophilic microbes through the analysis of their genome sequences. Hence, comparative genomic analyses of genomes allowed the identification of distinctive genes and metabolic pathways involved in the extremophilic way of life. Such analyses provided key data that enabled us to understand gene functionality across organisms and environments and track the evolutionary events involved in environmental adaptations at the population and strain levels.

Introducing your Author Service Manager

Dr. Maja Bozicevic

As an Author Service Manager my responsibilities include monitoring and facilitating all publishing activities for authors and editors. From chapter submission and review, to approval and revision, copyediting and design, until final publication, I work closely with authors and editors to ensure a simple and easy publishing process. I maintain constant and effective communication with authors, editors and reviewers, which allows for a level of personal support that enables contributors to fully commit and concentrate on the chapters they are writing, editing, or reviewing. I assist authors in the preparation of their full chapter submissions and track important deadlines and ensure they are met. I help to coordinate internal processes such as linguistic review, and monitor the technical aspects of the process. As an ASM I am also involved in the acquisition of editors. Whether that be identifying an exceptional author and proposing an editorship collaboration, or contacting researchers who would like the opportunity to work with IntechOpen, I establish and help manage author and editor acquisition and contact.
