A new abundant nitrite-oxidizing phylum in oligotrophic marine sediments

R. Zhao, S. L. Jorgensen, A. R. Babbin

The paper identifies a new bacterial phylum, Candidatus Nitrosediminicolota, which oxidizes nitrite and resolves the abundance imbalance between ammonia-oxidizing archaea and canonical nitrite-oxidizing bacteria in marine sediments.

Genome-resolved metagenomics reveals abundant nitrate reducers and partitioning of nitrite usage within global oxygen deficient zones

I. H. Zhang, X. Sun, A. Jayakumar, S. G. Fortin, B. B. Ward, A. R. Babbin

The paper uses genome-resolved metagenomics to analyze 56 ODZ metagenomes, revealing that partial denitrifiers dominate nitrogen cycling and showing niche differentiation among nitrogen-cycling organisms.

Sinking diatom aggregates provide carbon to drive microscale denitrification in a bulk oxygenated ocean

D. Ciccarese, O. Tantawi, I. Zhang, D. Plata, A. R. Babbin

The paper demonstrates that sinking diatom aggregates can support denitrification in oxygenated ocean water, forming nitrite maxima through anoxic microsites.

Nitrite accumulation and the associated anammox bacteria niche partitioning in marine sediments

R. Zhao, A. R. Babbin, D. L. Roerdink, I. H. Thorseth, S. L. Jorgensen

This study identifies niche partitioning of anammox bacteria in marine sediments based on nitrite accumulation and substrate utilization differences.

Porous marine snow differentially benefits chemotactic, motile, and non-motile bacteria

B. Borer, I. Zhang, A. Baker, G. A. O'Toole, A. R. Babbin

This study shows that bacterial motility is essential for colonizing marine particles, while chemotaxis benefits at higher settling velocities, and non-motile bacteria disproportionately benefit from porous particle structures.

Aerobic Bacteria Produce Nitric Oxide via Denitrification and Trigger Algal Population Collapse

A. Abada, M. Sperfeld, R. Carmieli, S. Ben-Dor, I. Huang Zhang, A. R. Babbin, E. Segev

Aerobic bacteria produce nitric oxide via denitrification in oxygenated conditions, triggering algal population collapse through a cascade of NO-induced cell death.
