Biofuels
The international oil industry drives our economy and very life of the world. However, this resource is dwindling and has detrimental effects on our atmosphere. In order to reduce oil usage and dependence, we will improve the efficiency of bio-fuels by manipulating the microbes used in their creation. One of the proposed biofuels is using alkanes to make biodiesel. They are useful because they float when the cell lysed and only needs to be dewatered. One way to produce alkanes is through Acetyl-CoA. Acetyl-CoA is synthesized by pyruvate. Pyruvate kinase converts phosphoenolpyruvate (PEP) into pyruvate. Pyruvate kinase adds a phosphate group from PEP to ADP to yield ATP and pyruvate.

Our iGEM project this year is to overexpress pyruvate kinase in cyanobacteria. To do this, we will insert a hyperactive pyruvate kinase from a rabbit muscle, yeast, or mutant cyanobacteria. This will increase the production of PEP greatly within the cyanobacteria. The excess PEP will then be used in the production of alkanes. Then, we will place the cyanobacteria in a low oxygen environment which will further suppress the usage of energy by limiting the electron transport chain. This energy would then be passed to the production of alkanes. Testing will be done with lipid extraction and profiling assay.

Dr. Aron Fenton - [2]

Instructors

Eric Kessler

Mr. Kessler’s interest in biology can be traced to his youth on his family’s annual canoe trips where he was obsessed with catching turtles. He has earned three undergraduate degrees, in Education from UMKC, and Psychology and Zoology from the University of Texas. These studies were followed by a Masters in Biology from Emporia State University where he completed research on the retreat-site selection of woodland snakes. He complete 18 years at BVN before coming to CAPS, and maintains National Board Certification.

Kelley Tuel

Kelley Tuel will be the instructor for this course. She is a MS Degree candidate in Biology at Emporia State University. Her thesis is on the molecular genetics of Halobacterium sp. NRC-1, a salt-loving microbe, and its instructional use in high school classrooms. For her research, she isolated and named a previously undescribed mutant strain of the bacteria possessing a novel gene that can copy and paste itself around the genome. Colonies of the bacteria are in the adjacent image. Kelley holds undergraduate degrees in Biology and Education from KSU, and has previously taught high school Biology and AP Biology.

Joe Whalen

Mr. Whalen began his adult life in biology as a commercial fisherman in Alaska. His interest in the outdoors led him to complete an undergraduate degree in Environmental Science which he earned from the University of Kansas. From there he worked as a liaison between research and high school education as a GK-12 Fellow, and then completed three years teaching Biology, Zoology, AP Biology, and some physical science at Blue Valley High School. Before returning to CAPS he completed his Masters in Molecular and Cellular Biology at Oregon State University, where he studied genome defense mechanisms in the fungus, Fusarium graminearum. Mr. Walen is currently responsible for teaching the Bioscience Research course.
