Microbial Population Dynamics of Periphyton Biofilms in White Clay Creek

800 532 Stroud Water Research Center

Funded by: Stroud Water Research Center

Starting in the summer of 2011, Stroud Center scientists deployed glass slides into three reaches of White Clay Creek with distinct streamside land uses: mature forest, restored but immature forest, and meadow from upstream to downstream; microbial biofilms colonized the glass slides. Molecular DNA fingerprints demonstrated variations of biofilm population structures on both natural surface and glass slides. Comparing the results from other projects, the Stroud Center found that the surfaces on which microorganisms grow may be one of the most important environmental drivers for the growth of microorganisms.
