Molecular Analysis of Anaerobic Psychrophilic Bacteria
Bacteria,algae and also metazoans may live at temperature sbelow 0°C and survive ice formation in al lbody compartments, 1 ,2.In the Antarctic Dry Valleys, 3, microorganisms live at 35°C. Bacteria in culture metabolizeandreproduce, 4 ,at 10°C. In order to identify and characterize new species we sug...
