Analysis of five complete genome sequences for members of the class Peribacteria in the recently recognized Peregrinibacteria bacterial phylum

Lifestyle and ecosystem impacts are predicted and rendered as a cell cartoon

Scientific Achievement

Complete genomes reconstructed for five closely related and highly novel groundwater-associated bacteria were used to predict their environmental impact. The genomes define a new Class in Peregrinibacteria, potentially a new phylum.

Significance and Impact

Complete genomes from complex metagenomes are essentially unprecedented. Having such high quality sequences is critical for accurate ecological and evolutionary analyses.

Research Details
  • Field samples were collected, DNA extracted and shotgun sequenced
  • Advanced bioinformatics approaches were used to recover draft genomes and curate them to completion
  • Phylogenetic analyses place the newly sampled organisms in the Candidate Phyla Radiation as a sibling lineage to Peregrinibacteria.
