TL;DR: This study applies single-cell genomics to target and sequence 201 archaeal and bacterial cells from nine diverse habitats belonging to 29 major mostly uncharted branches of the tree of life and provides a systematic step towards a better understanding of biological evolution on the authors' planet.

TL;DR: Two standards developed by the Genomic Standards Consortium (GSC) for reporting bacterial and archaeal genome sequences are presented, including the Minimum Information about a Single Amplified Genome (MISAG) and the Minimum information about a Metagenome-Assembled Genomes (MIMAG), including estimates of genome completeness and contamination.

TL;DR: Differences in morphologic, physiologic, and genotypic differences between the new strains and the oceanospirilla justify the creation of a novel genus and species, Neptunomonas naphthovorans.

TL;DR: The initial characterization of a member of the Korarchaeota with the proposed name, “Candidatus Kor Archaeum cryptofilum,” which exhibits an ultrathin filamentous morphology is reported, suggesting that the organism relies on a simple mode of peptide fermentation for carbon and energy and lacks the ability to synthesize de novo purines, CoA, and several other cofactors.

TL;DR: Nitrate consumption, along with the results from the 14C radiolabel study, are consistent with the oxidation of naphthalene coupled to denitrification for Nap-3-1 and nitrate reduction to nitrite for NAP-4, the first report the authors know of that demonstrates nitrate-dependent anaerobic degradation and mineralization of nphthalene by pure cultures.
