Thermoalkaliphilic Microbes

Chapter
Part of the Cellular Origin, Life in Extreme Habitats and Astrobiology book series (COLE, volume 27)

Abstract

Alkaliphilic and thermophilic microbes are an exciting group of extremophiles, which thrive in environments with both extreme conditions. Thermoalkaliphilic microbes have been isolated from a variety of niches including alkaline and thermobiotic as well as mesobiotic and neutrophilic soils and sediments. Their adaptation to both high pH and elevated temperatures draws attention not only because they are potential sources of industrially important enzymes but also because of their adaptive mechanisms to external environmental conditions, and they could be considered as model organisms for extraterrestrial life. Thermoalkaliphiles neither represent the most thermophilic nor the most alkaliphilic microorganisms but represent thermophilic ones among the alkaliphiles and vice versa. The relevance of recombinant biological approaches in revealing metabolic potential within the communities of extreme ecosystems is undisputable, but in this post-genomics era, the importance of developing innovative isolation and cultivation methods for extremophiles remains an important objective in gaining a widespread picture of their ecological importance and physiology. There is a need to stimulate isolation and characterization of extremophiles by utilizing current knowledge of molecular biology, biochemistry, physiology, and, of course, microbiology.
