Adapting tools and functionalities in KBase to support a systems biology approach to understanding interactions in bioenergy-relevant microbial communities


A science focus area (SFA) is a research project funded by the Department of Energy (DOE) to further scientific advancement and support the DOE’s Office of Science mission. The LLNL Biofuels SFA, at Lawrence Livermore National Laboratory, is focused on the community systems biology of microbial consortia that are closely associated with bioenergy-relevant plants and algae. They focus on linking microscale impacts of single cells on system scale processes, applying quantitative isotope tracing of elemental exchanges and various ‘omics-based approaches. They also utilize constraint-based genome-scale metabolic modeling to predict and test interactions within microbial communities.

In the immediate future, they are seeking to improve the quality of genome annotations to improve draft metabolic models within KBase, by developing tools for importing, comparing, and merging metabolic annotations. This will both expedite the curation process during model building and produce the high-quality, multi-evidenced curated models needed to investigate the complex interactions within microbial communities.

Longer term, they seek to engage with KBase to interpret and integrate their data streams to further their goal to understand and predict ecological, biophysical, and biochemical dynamics of multi-taxa communities, as well as the metabolite fluxes that regulate trophic interactions.

Collaborative Data Object

New Functionality:

  • Create annotation tools that accept multiple lines of evidence to determine an optimal consensus annotation
    • This would allow annotation data like EC numbers, KEGG, and MetaCyc reaction identifiers to be combined for more accurate draft metabolic models

New Apps:
