It is very important to control microbial activity in cutting fluid containers. Both bacteria and fungi can cause problems because they metabolize the components of the cutting fluid, resulting in the production of biofilm/mucus (large quantities of biofilm/mucus can exacerbate foaming problems and sticky surfaces) and secondary metabolites in the form of short-chain organic acids. The latter can result in a lower pH of the cutting fluid and an increased risk of corrosion. It is also important to note that high levels of bacteria and fungi can cause health problems for those operating the machines.

Other signs of bacterial growth are a bad smell and fungal/bacterial film on top of the cutting fluid.
