Biofouling
Figure 1 shows an image taken with a confocal laser scanning microscope. Here we see details of the biofilm architecture and staining reveals different activities. A beautiful picture indeed.
Figure 2 shows a large biofilm deposit recovered from the feed stream of a pulp and paper manufacturing system; clearly a major biofouling problem.
Figure 3 shows a 3-inch diameter impeller in a fermenter which is severely fouled by a fungal biofilm. Photo by Andy Zwister.
