Limits to Life at Low Temperatures and at Reduced Water Contents and Water Activities,eratures that permit its existence. These limits, however, do not apply to cell survival. Some cells can survive the closest attainable approach to 0 K, and some can survive the loss of over 99% of their water.

Biological Limits of Temperature and Pressure,ld and under pressure. Since bacteria have the ability to adapt to environmental extremes, a close examination for the presence and/or growth of bacteria at high and low temperatures, low temperature and reduced pressure (less than 1 atm), low temperature and increased hydrostatic pressure should be

Endolithic Microbial Life in Hot and Cold Deserts, are discussed on a comparative basis. Quantitative estimates of biomass are comparable in hot and cold deserts. Despite the obvious differences between the hot and cold desert environment, survival strategies show some common features. These endolithic organisms are able to ‘switch’ rapidly their m

Purification and Properties of Malate Dehydrogenase from the Extreme Thermophile ,,termined as 73 000 daltons and it is composed of two subunits, each with a molar mass of 37 000. Initial velocity studies with oxaloacetic acid and NADH as substrates at pH 8.1, over a range of temperatures, indicate that the enzyme operates via a sequential type mechanism. Van’t Hoff plots of the k

Halophily and Halotolerance in Cyanophytes,tion between halophilic (Na.-requiring) and halotolerant organisms is not adequate to describe the entire spectrum of adaptations to salt. The classical division into stenohaline (narrow) and euryhaline (wide) adaptational types, with optima identified as oligo-, meso- and polyhaline, better reflect

,The Evolution of the Solar ‘Constant’,which life originated and continues to thrive. What can we say about the history of the Sun? Has the solar ‘constant’, the rate at which energy is received by the Earth from the Sun per unit area per unit time, been constant at its present level since Archean times? Three mechanisms by which it has
