Abstract
ABSTRACT To verify whether members of the phylum Candidatus Patescibacteria parasitize archaea, we applied cultivation, microscopy, metatranscriptomic, and protein structure prediction analyses on the Patescibacteria-enriched cultures derived from a methanogenic bioreactor. Amendment of cultures with exogenous methanogenic archaea, acetate, amino acids, and nucleoside monophosphates increased the relative abundance of

Abstract
AbstractTo verify the parasitic lifestyle ofCandidatusPatescibacteria in the enrichment cultures derived from a methanogenic bioreactor, we applied multifaceted approaches combining cultivation, microscopy, metatranscriptomic, and protein structure prediction analyses. Cultivation experiments with the addition of exogenous methanogenic archaea with acetate, amino acids, and nucleoside monophosphates and 16S rRNA gene sequencing confirmed the increase in the relative abundance ofCa.

Symbiosis between Candidatus Patescibacteria and Archaea Discovered in Wastewater-Treating Bioreactors

Ca. Patescibacteria
Abstract
One highly diverse phylogenetic group of Bacteria, Ca . Patescibacteria, remains poorly understood, but, from the few cultured representatives and metagenomic investigations, they are thought to live symbiotically or parasitically with other bacteria or even with eukarya.

Complete Genome Sequence of “ Candidatus Hydrogeosomobacter endosymbioticus,” an Intracellular Bacterial Symbiont of the Anaerobic Ciliate Scuticociliate GW7

Names
Ca. Hydrogenosomobacter endosymbioticus
Abstract
The bacterium “ Candidatus Hydrogenosomobacter endosymbioticus” is an intracellular symbiont of anaerobic scuticociliate GW7, which is associated with hydrogenosome together with methanogenic archaea. Here, we report a complete genome sequence of the symbiont consisting of 827 kbp. Knowing this sequence would contribute to the understanding of the metabolic interactions and evolution of the tripartite symbiosis.
