Pseudomonas From Extreme Environments: Physiological and Molecular Adaptations.

Abstract

Extremophiles are defined as organisms that grow under environmental conditions considered extreme by human standards, such as high/low pH, high/low temperature, high radiation, high salinity, high pressures, high desiccation etc. Research on extremophiles has led to several advances in molecular biology and bioengineering, providing new insights about the origin of life on Earth and the possibility of interplanetary life. Although most Pseudomonas are mesophilic, some species can grow in extreme environments. Even so, Pseudomonas with these characteristics still receive little attention. This review seeks precisely to help raise interest in the topic by compiling part of the information about extremophile/tolerant Pseudomonas. Resistance to cold, heat, extreme pH, UV, salinity and desiccation were evaluated.
