MIC Information: MIC Testing

The following bacteriia types are identified in the water and/or deposit test. An approximate population for each is included in the report.


Acid Producing Bacteria

Chemical corrosion is a major player in the MIC corrosion Process.

APB Are capable of producing inorganic & organic acids (which corrode the iron) as well as providing nutrients for sulfate reducing bacteria (SRB). They contribute to pitting & pin-hole leaks.

Sulfate Reducing Bacteria

SRB are probably the most destructive group of the MIC bacteria as they are a primary cause of pitting & pin-hole leaks.

They mine iron from the pipe, take sulfur from the water & produce iron sulfide (black solids) & hydrogen sulfide gas (rotten egg smell).

Iron Related Bacteria

IRB are iron utilizing. They build tubercles & are responsible for the destructive corrosive process in iron & steel. They cause pitting & pin-hole leaks.

IRBs are known to have a symbiotic relationship with other groups of MIC bacteria.

Slime Forming Bacteria

Slime forming bacteria live in conjunction with APB, SRB & IRB.

They are an important part of the MIC process, often acting as the transient from aerobic to anaerobic conditions & as a support system for the corrosion process.
