Biofilms are usually an essential part of the MIC process. Understanding how they work will help you undertand the damage that MIC can cause.
A biofilm is the start of a colony of different species of bacterium or a single species of bacterium:
Biofilms are aerobic on the outside & anaerobic on the inside. This allows for the formation of micro-environments that facilitate the growth of both types of bacteria.
The polymers created allow attachment points for additional bacteria and nutrients.
A mature biofilm creates tubercles (see Tubercles).
|Where do biofilms form and why?
Are biofilms necessary for MIC?
Not always. Anaerobic bacteria can survive & function well in low oxygen conditions, such as wet ystems.
Only Pitting will be observed in such conditions.
