(top panel), and a series of class (a), intermediate, and class (b) metals and the bacterium, Saccharomyces cerevisiae (bottom panel). The units of K in the top panel are M from an algal suspension with 0.5 x 10 to 0.1 X10" M of dissolved metal.

One of the early enthusiasts of microscopy was Antoni van Leeuwenhoek. During the sixteenth century he constructed over 500 single lens microscopes. While crude by today s standards, van Leeuwenhoek s microscopes revealed an array of microbial life. For example, his descriptions of organisms found in lake water were the first observations of the green algae called Spirogyra and another microbe that came to be known as Vorticella. Finally, his observation of animacules in tooth plaque was the first visual detection of bacteria. 

Figure 5. The bones of a cow in the stream a few meters from the westernmost source of the Rio das Mortes. The minerals released during the decompoafron of the carcass apparently supported the development of a dense mat of Spirogyra sp. and other algae, which were moribund at the time of the analyses.
