A Biofilm’s Bio


STUDENTS: Module 1: Science in the Personal & Social Perspectives

Our icon for risk.A Biofilm's Bio Links science and emerging technology to environmental health concerns.

The term biofilm is so new to science that it may not yet appear in your textbook. A biofilm is a layer consisting of various combinations of many different organisms, (frequently, bacteria.) The common factor among these organisms is that they grow together in an aqueous (water) environment attached (adhered) to a solid surface, or substrate, forming a film.

A dentist works on his patient.Dental plaque was among the first groups of biofilms to be studied. Teeth provide a hard surface on which biofilms can attach themselves. Saliva and the remains of food we eat are both sources of nutrients for the bacteria that contribute to the formation of dental plaque and associated periodontal diseases.


Not all biofilms are harmful. Some biofilms are part of the normal flora inside our bodies and others help our bodies produce vitamins. A new research area known as bioprospecting has developed from the use of biofilms in biotechnology.
