Bacteria Removed From Water With Simple Pine Tree Filter Say MIT Researchers MIT group shows xylem tissue in sapwood can filter bacteria from contaminated water. If you’ve run out of drinking water during a lakeside camping trip, there’s a simple solution: Break off a branch from the nearest pine tree, peel away the bark, and slowly pour lake water through the stick. The improvised filter should trap any bacteria, producing fresh, uncontaminated water. A false-color electron microscope image showing E. coli bacteria (green) trapped over xylem pit membranes (red and blue) in the sapwood after filtration. Researchers design a simple filter by peeling the bark off a small section of white pine, then inserting and securing it within plastic tubing.
