Bacterial sequences composition of light DNA fraction isolated from 13C-straw-amended soil treatment
soil metagenome
This sample is part of an incubation experiment where tropical soil was incubated in laboratory amended or not with 13C labelled wheat straw and in the presence of three earthworm species (Pontoscolex corethrurus, Kynotus parvus and Dichogaster saliens). DNA has been extracted from soil or from earthworm casts and DNA-SIP approach allowed to separate DNA from bacteria fed on the labelled-straw (Heavy DNA fraction) vs bacteria fed on soil organic matter (Light DNA fraction). This biosample corresponds to the light DNA fraction of the straw-amended soil (without earthworm).
