Metagenome-Assembled Genomes from Photo-Oxidized and Nonoxidized Oil-Degrading Marine Microcosms.

We performed deep metagenomic sequencing on hydrocarbon-degrading marine microcosms designed to experimentally determine the effect of photo-oxidation on oil biodegradation dynamics. Assembly, binning, and dereplication yielded 73 unique metagenome-assembled genomes (MAGs) from 6 phyla, of which 61 are predicted to be over 90% complete.

Draft Genome Sequence of the Marine sp. Strain LSUCC0859.

A new marine sp. strain, LSUCC0859, was isolated off the coast of Louisiana with artificial seawater via high-throughput dilution-to-extinction (DTE) cultivation. The 2,168,862-bp genome sequence provides opportunities to investigate the biology of a poorly understood lineage within the .

Ecophysiology of the Cosmopolitan OM252 Bacterioplankton ().

Among the thousands of species that comprise marine bacterioplankton communities, most remain functionally obscure. One key cosmopolitan group in this understudied majority is the OM252 clade of . Although frequently found in sequence data and even previously cultured, the diversity, metabolic potential, physiology, and distribution of this clade has not been thoroughly investigated.

Mechanisms driving genome reduction of a novel Roseobacter lineage.

Members of the marine Roseobacter group are key players in the global carbon and sulfur cycles. While over 300 species have been described, only 2% possess reduced genomes (mostly 3-3.5 Mbp) compared to an average roseobacter (>4 Mbp).
