It's all about the bugs ...

... so says this report.
"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.
So what effect did that have?
Revising the computer model predictions to take the soil enzymes' impact on CO2 into account reduces the discrepancies between the model and atmospheric observations, according to the paper whose lead authors are Lisa Wingate and Jérôme Ogée, representing the University of Edinburg and the French National Institute for Agricultural Research, respectively.
Sounds like it's time to look into what molecular probes exist for this enzyme (carbonic anhydrase) ...

hmmm, interesting.
from the PNAS paper:"the abundance and location of CA in soils is still somewhat unclear" I would think think that this could vary greatly on the soil and on the community of microbes in the soil. I would also be curious if any other enzymes could cause a similar fractionation signature.
