Better Microbial Genome Binning with MetaBAT

DOE JGI researchers develop an automated software tool that can scale to handle complex metagenome datasets. The Science: DOE JGI researchers have developed an automated tool called MetaBAT that automatically groups large genomic fragments assembled from metagenome sequences to reconstruct single microbial genomes. The Impact: The ability to accurately and efficiently reconstruct individual microbial genomes… [Read More]

A History of Phage-Host Interactions With Help From CRISPRs

A tool to help microbial ecologists link phages to hosts in ecological studies. The Science: Using metagenomic datasets produced from the Iron Mountain site in Northern California and customized tools, researchers used bacterial spacer sequences commonly called CRISPRs to link phage and hosts in ecological studies. The Impact: Interactions between uncultivated microbes and their phage… [Read More]

A Single-Cell Pipeline for Soil Samples

Scientists evaluate a process that uses NanoSIMS and Raman microspectroscopy for in situ microbial studies. The Science: To investigate in situ function of uncultivated microbes, scientists evaluated a process for preparing soil samples for single-cell analysis methods. The Impact: The process allows researchers to efficiently analyze microbial activities at the single-cell level in soil systems,… [Read More]

Expanding Barley Genetics Resources

Genomic regions containing two-thirds of all annotated barley genes have been sequenced. The Science: Researchers generated nearly 16,000 sequences of gene-containing regions for barley, mapping approximately two-thirds of all annotated barley genes. The Impact: While researchers continue to work on a complete reference sequence for the barley genome, the determination of improved sequence assemblies for… [Read More]

Seeking “Gold Standard” Wastewater Treatments

Metagenomic analyses lend insights into how microbes break down wastewater contaminants. The Science: Researchers conducted analyses of microbial communities in laboratory-scale bioreactors breaking down contaminated wastewater from gold ore processing. The Impact: In this “first application of genome-resolved metagenomics” to characterize bioreactors involved in gold ore processing, the data reveal how the bioreactors utilize available… [Read More]

First Public Resource for Secondary Metabolites Searches

IMG-ABC allows researchers to link sequencing data and the search for novel biosynthetic gene pathways.

Celebrating the Eucalyptus Reference Genome

New Phytologist dedicates an entire issue to various research directions based on the tree genome. The Science: Building off the Eucalyptus grandis tree genome that researchers at the DOE Joint Genome Institute helped sequence and analyze, several researchers demonstrate the utility of the reference genome in the June 2015 special issue of New Phytologist. The… [Read More]

The Most Complete Functional Map of an Entire Enzyme Family

DOE-funded researchers develop a new process for annotating cellulose-degrading enzymes. The Science: Researchers at two Department of Energy-funded Scientific User Facilities collaborated with one of three Bioenergy Research Centers to develop and analyze high-resolution crystal structures of an enzyme from the cellulose-degrading GH55 family. They then went further and were able to apply a variety… [Read More]
