Microbes Persist SFA

Foundation for Understanding and Prediction of Microbial and Viral Ecogenomics in Soil

The Microbes Persist: Systems Biology of the Soil Microbiome Science Focus Area (SFA), led by Dr. Jennifer Pett-Ridge at Lawrence Livermore National Laboratory (LLNL), aims to understand the critical role that microbes play in the stabilization and persistence of soil carbon. Microbes Persist does so by studying microbial biochemistry, functional potential, and physiology of the soil microbiome. This SFA is producing hundreds of stable isotope probing genome-resolved metagenomes and will be implementing new tools in KBase to tackle the bioinformatic challenges associated with the corresponding data analysis. In addition, collaborations with the Banfield group (University of California, Berkeley) addresses microbial metagenome curation efforts, and the Sullivan group (The Ohio State University) has contributed iVirus tools to KBase.

Collaborative Development Projects

Towards quantitative theory-based predictions of soil microbial fitness, interaction, and function in KBase.

Quantitative Stable Isotope Probing (qSIP)*

Building community standards for qSIP sample metadata that links directly to analysis tools/workflows, and establishing a community database resource of qSIP experiments in KBase. Proposed standards for sample metadata coming soon as preprint. Tools and database are still in development.

Integration of Dynamic Energy Budget (DEB) microTrait^

Connects genomes and ecophysiological traits to build trait-based models for guild profiles with DEB profiles (still in development).

Metagenomic Functionality#

  • FixAME enables curation of assembly quality in metagenome bins (still in development)

Viral Tools&

  • Two tools from iVirus, a tool designed to explore viral ecology and bring bioinformatic analyses to the study of viral genomes
  • VirMatcher predicts virus-host relationships using variety of bioinformatic methods: host CRISPR-spacers, integrated prophage, host tRNA genes, and k-mer signatures calculated by WIsH (Released)
  • PhATE, a phage functional annotation pipeline developed at LLNL (still in development)
