Enzymes to Reduce Carbon Dioxide Emissions - Carbonic Anhydrase (CA)

  1. 1. Enzymes to Reduce Carbon Dioxide Emissions: Carbonic Anhydrase (CA) Presented by Raja Wajahat
  2. 2. • Enzymes are biological catalysts that accelerate chemical reactions, • such as the conversion of gaseous carbon dioxide into carbonates. 2Presented by Raja Wajahat
  3. 3. • Although naturally occurring enzymes would be ideal for converting human-generated carbon dioxide emissions into carbonates, • they are generally incapable of coping with the extreme conditions of industrial plants 3Presented by Raja Wajahat
  4. 4. • Scientists are now developing artificial enzymes that can withstand the harsh environments of industrial plants while accelerating chemical reactions • It is aimed to create a clean, cheap, practical and socially responsible solution for global warming by reducing carbon dioxide emissions 4Presented by Raja Wajahat
  5. 5. • Using the artificial environment, the researchers will ensure that their artificial enzymes can function properly under extreme conditions consisting of – hot, – corrosive, – poisonous and – sticky smoke • as well as soot and other gases produced by power plants. 5Presented by Raja Wajahat
  6. 6. Carbonic Anhydrase (CA) • The team is basing the development of its artificial enzyme on naturally occurring carbonic anhydrase (CA), which accelerates the conversion of carbon dioxide into carbonates. • Carbonic anhydrase is capable of turning carbon dioxide molecules into carbonates at a rate of one million molecules per second. 6Presented by Raja Wajahat
  7. 7. Random Mutagenesis • Scientists plan to modify and multiply the genes encoding for carbonic anhydrases using a molecular technique called random mutagenesis. • The researchers will then place the mutated genes in the artificial environment to see which ones are most effective at converting carbon dioxide into carbonates. 7Presented by Raja Wajahat
  8. 8. • The best mutations will then be put through the modification and multiplication processes again. • The researchers will repeat the whole process until they have isolated a mutated gene encoding for recombinant carbonic anhydrase that can convert carbon dioxide into carbonates under industrial conditions. 8Presented by Raja Wajahat
  9. 9. • With the help of artificial enzymes, • carbon dioxide-converted carbonates could be used in everything • from baking soda and chalk to Portland cement and lime manufacturing 9Presented by Raja Wajahat
