Understanding the Role of Methanotrophs on Pharmaceutical Transformations
- Do aerobic methane oxidizing bacteria biotransform pharmaceuticals?
- If so, to what extent do the particulate and soluble methane monooxygenase associate with pharamceutical biotransformation?
I conducted batch experiments using Methylosinus trichosporium Ob3b. The use of copper to change the expression of methane monooxygenase (soluble MMO at low copper concentrations and particulate MMO at high copper concentrations) has been well studied in this organism. I conducted two batch experiments with media containing a suite of pharmaceuticals and either high copper content or low copper content. I tested the degree of transformation under both conditions. I found that the pharmaceutical transformation was significantly greater in the sMMO enriched culture than the pMMO enriched culture for a variety of compounds.
