Dynamics of 18O Incorporation from H 2 18O into Soil Microbial DNA

Abstract

Heavy water (H 2 18 O) has been used to label DNA of soil microorganisms in stable isotope probing experiments, yet no measurements have been reported for the 18O content of DNA from soil incubated with heavy water. Here we present the first measurements of atom% 18O for DNA extracted from soil incubated with the addition of H 2 18 O. Four experiments were… (More)
