Biofilms as Biobarriers
Lennox, John; Ashe, Jeffrey
American Biology Teacher, v71 n1 p20-26 Jan 2009
In a climate of increased concern for the environment and its protection, teachers in disciplines as diverse as biology, microbiology, environmental studies, and environmental engineering may be seeking teaching materials and laboratory exercises that will enable them to introduce these new concepts into their classrooms and laboratories. The materials and exercise presented in this article are intended to enable teachers to illustrate the seamlessness of the intersection between the theory of microbiology and the practice of environmental protection. This article describes an exercise which represents a safe and inexpensive method for introducing biofilms and biobarrier technology into the undergraduate or precollege curriculum either as a classroom exercise or as the focus of an independent student project. It demonstrates the close relationship between microbiology, environmental engineering, and environmental protection and shows how biofilm grown in a porous matrix can reduce underground water movement and the transport of any contaminants the water might be carrying.
