Microorganisms cited as missing factor in climate change equationThose seeking to understand and predict climate change can now use an additional tool to calculate carbon dioxide exchanges on land, according to a scientific journal article publishing this week.
The research, publishing in the Proceedings of the National Academy of Sciences, incorporates into global computer models the significant impact an enzyme, carbonic anhydrase, has on the chemical form of carbon dioxide released from the soil and reduces uncertainties in estimates of CO2 taken up and released in terrestrial ecosystems.
The same enzyme is present in foliage and soils, but leaves a different imprint on CO2 involved in photosynthesis and respired by soils.
"Our paper presents measurements from all the major regions of the world where we have experimentally determined the effect of this enzyme, produced by many microorganisms, on carbon dioxide released from the soil," said Dr. Behzad Mortazavi, an assistant professor of biological sciences at The University of Alabama, and a co-author of the article.
