Cloning of the Outer Membrane f-type Cytochrome(OmcF) gene

  • One of the best and most studied organisms on the production of bioelectricity would be the anaerobic bacteria of Geobacter sulfurreducens.This microbe is able to produce high current densities in microbial fuel cells and there has been broad studies on extracellular electron transfer to Fe(III) oxide in this organism which might provide insights into extracellular electron transfer to electrodes. Through some research Geobacter sulfurreducens has been shown to have several outer membrane cytochromes that may be involved in the electricity production. One particular gene, the outer membrane f-type cytochrome or OmcF gene has shown its involvement in the electricity production process through a study done by researchers at the University of Massachusetts. In this study they worked with OmcF deficient microbes and found that there was a significant decrease in the reduction of Fe(III) and a decrease in current production in this microbe. By the tests done by the researches, OmcF is is shown to be required for proper levels of transcription of other genes that are highly regulated when this microbe grows on the surface of an anode of a microbial fuel cell as compared to the growth on a soluble electron acceptor. Thus showing that the OmcF plays a role in regulating proteins that help aid in the electron transport across the cell membrane.

We are planning on cloning this OmcF gene and seeing how the result will effect the bacteria E.coli in hopes of creating a more well understood process of electricity production with the future hope of creating a more effective electrical source.

  • List all the steps that are needed to complete your project
  • Do not go into experimental details and don't list procedures. Just list the major steps necessary to complete your project
  • Please also make yourself familiar with uploading pictures and *.ppt files

Important Results and Milestones

  • keep track of your most important results and refer to the corresponding page in your notebook
  • upload important pictures (don't forget to label them! Powerpoint is very convenient). Remember: these will become quite handy later in your summary report or final presentation. If you do label and upload the pictures as soon as you got them, your summary report can be written much more effortlessly (do you usually procrastinate? This is chance to do some work before hand that frees you up for finals week).
