Low
Magnification View of Bacteria Colony
This
SEM micrograph shows a low
magnification view of a bacteria colony forming on a Silicone tube. The
overall image covers an area of approximately 500 microns (.5 mm) in
size. Examining the details of the photograph, individual bacterium can
be seen, embedded in a biofilm. The colony is large enough to be seen by
the naked eye. To the naked eye, the bacteria colony looks like a cloudy
gossamer structure which resembles a small cotton ball. This colony
looked white to the naked eye. We have observed other colonies which
look like small rusty spots to the naked eye. The image below shows the
tube as seen from a low magnification view optical microscope.

The silicone tube pictured above shows
several patches on the inner lumen of the tube. The dark patches show
the bacteria colony, which can easily be seen by the naked eye. To the
naked eye, the patches look white and like little patches of cotton. |
