3 CO2 Bicarbonate Calcium Bicarbonate Ca(OH)2 + CO2 → CaCO3 + H2O CO2 + H2O «-» H+ + HCO3-Or Sodium bicarbonateCO2 + 2NaOH → Na2CO3 + H2O
4 Implementation1. The bacteria need to uptake CO2 (or it can use it’s own waste CO2)2. the bacteria need to be able to convert CO2 CaCO33. The CaCO3 needs to leave the bacteria (so that you don’t have to kill the bacteria to collect the precipitate)Would the bacteria get rid of the precipitate on its own?
5 Breaking it down Maximizing CO2 uptake by bacteria (1 person) Trying different methods of CO2 CaCO3Make the bacteria produce a CO2CaCO3 converter enzyme (2 people)Make the bacteria produce Ca(OH)2 (Ca + NaOH) so that when the CO2 was absorbed the calcium carbonate would just precipitate out. (2 people)Can the bacteria survive with NaOH everywhere?Make bacteria that can survive with NaOH everywhere.
6 CO2 Solution sort of…did it already. “The company has genetically engineered E. coli bacteria to produce an enzyme that converts carbon dioxide into bicarbonate. The enzyme sits at the core of a bioreactor technology that could be scaled up to capture carbon-dioxide emissions from power plants that run on fossil fuels.”
