Project type

Exploratory Research

The formation of organo-mineral complexes, particularly in the deep soil horizons is a key process in the long-term stabilization and therefore persistence of carbon in soils. However, there is…

Automating Microbial Community Phenotyping within Synthetic Soil Aggregates

Environmental Molecular Sciences Laboratory

Principal Investigator

Jayde Aufrecht

Microbial hotspots are the sites of nearly all biogeochemical transformations (BGT) in the soil. Unfortunately, the small size (µm to mm) and transient existence (hours to days) of microbial…

Temporal Dynamics of Microbial Traits Driving Divergent Patterns of Carbon Flow During Surface Litter Decomposition
