摘要

PAST ARTICLES IN THIS COLUMN have discussed ongoing research to better understand how bacteria adhere to surfaces and form biofilms. This issue is important to users of metalworking fluids because bacterial contamination has been found to decrease operating life and can lead to health and safety concerns for workers monitoring these fluids. In a previous TLT article, research detailing how a specific bacterium (Caulobacter crescentus) adheres to a system through a reversible, irreversible two-stage process was discussed. In the first step, the bacterium will establish a low adherence to a specific surface to determine if it is the right location. Then a stronger polysaccharide-based adhesive is produced and secreted in the second step to enable the bacterium to remain on the surface in an irreversible manner for a long period of time. This natural adhesive has the performance attributes of super glue.
