              CO2 Bicarbonate
                          3

 Calcium Bicarbonate
 Ca(OH)2 + CO2 → CaCO3 + H2O
 CO2 + H2O «-» H+ + HCO3-


 Or Sodium bicarbonate
 CO2 + 2NaOH → Na2CO3 + H2O
                      Implementation
                                  4

 1. 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 
  CaCO3
 3. 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?
                    Breaking it down
                                 5

 Maximizing CO2 uptake by bacteria (1 person)
 Trying different methods of CO2 CaCO3
   Make the bacteria produce a CO2CaCO3 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.
          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.”
