We explored microbial contributions to decomposition using a sophisticated approach to DNA Stable Isotope Probing (SIP). Our experiment evaluated the dynamics and ecological characteristics of functionally defined microbial groups that metabolize labile and structural C in soils. We added to soil a complex amendment representing plant derived organic matter substituted with either  13 C-xylose or  13 C-cellulose to represent labile and structural C pools derived from abundant components of plant biomass. We found evidence for  13 C-incorporation into DNA from  13 C-xylose and  13 C-cellulose in 49 and 63 operational taxonomic units (OTUs), respectively. The types of microorganisms that assimilated  13 C in the  13 C-xylose treatment changed over time being predominantly  Firmicutes  at day 1 followed by  Bacteroidetes  at day 3 and then  Actinobacteria  at day 7. These  13 C-labeling dynamics suggest labile C traveled through different trophic levels. In contrast, microorganisms generally metabolized cellulose-C after 14 days and did not change to the same extent in phylogenetic composition over time. Microorganisms that metabolized cellulose-C belonged to poorly characterized but cosmopolitan soil lineages including  Verrucomicrobia, Chloroflexi , and  Planctomycetes .
