Bacteria

This is an SEM micrograph of a bacteria colony forming. The bacterial colony is well developed, and is showing the initial development of a biofilm. Some of the round Cocci type bacteria are suspended in an adhesive matrix. The relative maturity of this matrix varies across the photograph. The matrix is developed enough that the bacteria are clearly bound to each other, and to the substrate below, but the top layers of individual bacteria are still clearly visible.
