Control of microorganisms
After reading this article you will..
- understand the different type of problems which uncontrolled growth of microorganisms can create.
- understand that in control of microorganisms the targets can vary. In some cases, reaching of the control target may require complete eracidation of all microbial activity, whereas in another case it can be sufficient to maintain microbial activity to a level that causes pH changes, as an example.
