As part of the search for better ways to track and clean up soil contaminants, scientists at Brookhaven National Laboratory and Stony Brook University have developed a new way to "image" the internal chemistry of bacteria. The technique will allow scientists to "see" at the molecular level how soil-dwelling microbes interact with pollutants, help scientists better understand and prevent bacterial diseases, and possibly find ways to detect or disable bacteria used in a terror attack.
This figure shows a single cell of Clostridium sp. (a strictly-anaerobic, soil-dwelling bacterium) as imaged by scanning trasmission x-ray spectromicroscopy (left). By analyzing the x-ray absorption spectrum, scientists can pick up subtle biochemical differences between the bulk of the cell body (yellow) and a tiny spore (green) forming inside. This early stage of spore formation would be invisible to other imaging techniques.
