AB  - In this study, CO2 sequestration was investigated through the microbially-induced 
      calcium carbonate precipitation (MICP) process with isolates obtained from a cave 
      called 'Cave Without A Name' (Boerne, TX, USA) and the Pamukkale travertines 
      (Denizli, Turkey). The majority of the bacterial isolates obtained from these 
      habitats belonged to the genera Sporosarcina, Brevundimonas, Sphingobacterium and 
      Acinetobacter. The isolates were investigated for their capability to precipitate 
      calcium carbonate and sequester CO2. Biotic and abiotic effects of CO2 
      sequestration during MICP were also investigated. In the biotic effect, we 
      observed that the rate and concentration of CO2 sequestered was dependent on the 
      species or strains. The main abiotic factors affecting CO2 sequestration during 
      MICP were the pH and medium components. The increase in pH led to enhanced CO2 
      sequestration by the growth medium. The growth medium components, on the other 
      hand, were shown to affect both the urease activity and CO2 sequestration. 
      Through the Plackett-Burman experimental design, the most important growth medium 
      component involved in CO2 sequestration was determined to be urea. The optimized 
      medium composition by the Plackett-Burman design for each isolate led to a 
      statistically significant increase, of up to 148.9%, in CO2 uptake through 
      calcification mechanisms.
