CO2 Bicarbonate
3
 Calcium Bicarbonate
 Ca(OH)2 + CO2 → CaCO3 + H2O
 CO2 + H2O «-» H+ + HCO3 Or Sodium bicarbonate
 CO2 + 2NaOH → Na2CO3 + H2O
Implementation

 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

 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.”
