Many Microorganisms and some macro-organisms can live under extreme
conditions. For example, high and low temperature, acidic and alkaline
conditions, high salt areas, high pressure, toxic compounds, high level
of ionizing radiation, anoxia and absence of light, etc. Many organisms
inhabit environments characterized by more than one form of stress
(Polyextremophiles). Among them are those who live in hypersaline and
alkaline, hot and acidic, cold/hot and high hydrostatic pressure, etc.
Polyextremophiles found in desert regions have to copy with intense UV
irradiation and desiccation, high as well as low temperatures, and low
availability of water and nutrients. This book provides novel results of
application to polyextremophiles research ranging from nanotechnology to
synthetic biology to the origin of life and beyond.
