Literature Review • Rosenbaum, Miriam (2005) ‘Utilizing the Green Alga C.reinhardtii for Microbial Electricity Generation” • Direct electricity generation from microbial photosynthetic activity • Oxidative depletion of hydrogen, photosynthetically produced by C.reinahrdtii under sulfur deprived conditions, by polymer coated electro catalytic electrodes
Literature Review • Melis, Anastasios (2000) “Sustained Photobiological Hydrogen Gas Production upon Reversible Inactivation of oxygen Evolution in C.reinhardtii” • Method circumvents the severe oxygen sensitivity of the reversible hydrogenase by temporarily separating photosynthetic oxygen evolution and carbon dioxide accumulation
Literature Review • Posewitz, Matthew C. (2004) “Hydrogen Photoproduction is Attenuated by Disruption of an Isoamylase Gene in C.reinhardtii” • STA7 is an isoamylase gene in C.reinahrdtii, which is important for starch accumulation and metabolism, which plays an important role in hydrogen photoproduction
Literature Review • Logan, Bruce E. (2006) “Using Algae and other Biomass for Hydrogen Production in a Modified Microbial Fuel Cell” • A small voltage was applied (.25 V) to the algae, which generated pure hydrogen gas at the cathode
Do Ability • C.reinhardtii: Can be grown in the lab as done in previous years • Light Intensities: Different bulbs can be purchased and used in the school lights • Microbial Fuel Cell: A simple fuel cell is owned by the school
