Bench Biology

Bacteriological Analyses

The Bench Biology workgroup conducts bacteriological tests for enterococci, Escherichia coli, fecal coliforms and total coliforms. These bacteria are commonly found in the intestinal tract of warm-blooded animals. Their presence in water samples can indicate the potential presence of fecal pollution and enteric pathogens.

Biochemical Oxygen Demand (BOD)

Molecular Biology

The Biology Program's Molecular section uses microbial source tracking (MST) analyses to identify sources of fecal contamination in Florida’s waterbodies. Fecal indicator bacteria (FIB), like Escherichia coli (E. coli) and Enterococci, are commonly found in human and animal waste but can also live naturally in soil, sediment, water, periphyton, and biofilms.
