The James M. DuPont Meteorite Collection - snails. In barren, eroded soil, on wood, in sewage, on and under light transmitting rocks, and even in areas of comparatively recent volcanic activity (Treub, 1888), it has been found that blue-green algae are able to grow and survive. Furthermore, it has been de- termined that the Eh range of blue-green algae is from —0.200 to +0.700 volts and the H from 1.5 to 11 (Baas Becking et al., 1960). That they can resist desiccation for decades has been shown in the revival of species from old, stored soils (Bristol, 1919). Reproduction can be quite rapid, and oscillatorioid forms can develop macroscopic growth in a few hours on desert soil which has remained dry for a number of years. Prolonged resistance to desiccation has been found in a dried herbarium specimen of

The James M. DuPont Meteorite Collection - bacteria; A', three species of heterotrophic bacteria; L, methane producing bacteria. Redrawn from Baas Becking el al. (1960). Eh is expressed in millivolts. 346 Annals New York Academy of Sciences solutions containing 4 per cent CUSO4 in an industrial plant (Starkey and Waksman, 1943). These forms grow well when submerged in nutrient-enriched sulfuric acid solutions at pH values between 0.4 and 7.0. Some growth occurs at pH (2.5 normal H2SO4) even when solutions are saturated with CUSO4 . No study was made of the permeability of the cells to copper and hydrogen ions, but presumably there was little to no penetration. One alga is notable for its growth in acid solutions, a strain of Cyanidhim caldarium originally isolated from a hot spring containing 0.1 N H2SO4

The James M. DuPont Meteorite Collection - is that given by Baas Becking et al. (1960). These workers have summarized paired Eh-pH data for the growth of diverse microorganisms in natural environments and laboratory cultures. Although the Eh values may in some cases not represent truly reversible potentials they at least give a reproducible and reasonably accurate picture. Their results are shown graphically in figure 1. When the data for all microorganisms are combined and compared to Eh-pH measurements in natural surface waters of the earth, a complete overlap is observed. This suggests that there is probably no major aqueous environment that cannot be colonized by some microor- ganism. The range for growth and reproduction of microorganisms was found to lie between 850 mv.
