CO2 ?Bicarbonate

• 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
  its 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 dont 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 ?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 ofdid 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.
