During this specified factor assessment articles summarize the main impressive positive aspects of microorganisms which could continue to exist lower than severe stipulations. those microorganisms are tailored to dwelling at a hundred° C in volcanic springs, at low temperatures within the chilly polar seas, at excessive strain within the deep sea, at very high and low pH values (pH 0-1 or pH 10-11), or at very excessive salt concentrations (35%). the most recent findings at the molecular biology and the protein constitution of those unique organisms are provided. additionally, the capability functions of extremophiles are reviewed, together with the creation of enzymes, suitable solutes and using those extremophiles within the degradation of xenobiotics.

Prokaryotes Living Under Elevated Hydrostatic Pressure 25 Heterotrophic activity of marine bacteria isolated from surface waters appeared to be "considerably retarded" under these conditions, and similar resuks were obtained from experiments performed with deep-sea organisms . Several reviews intensively described these studies that used"in situ" experiments, shipboard analysis on decompressed and undecompressed samples [16, 17]. It was demonstrated that respiration of deep-sea bacteria was less affected by high pressure and low temperature than substrate incorporation, and concluded that probably no free-living bacteria adapted to deep-sea conditions existed [18-20].
