The apparent respiratory quotient for bacterioplankton remineralization of dissolved organic matter (DOM) is influenced by DOM composition and the metabolic potential of bacteria, accounting for variability in large-scale CO2 production estimates.

High salinities are thought to inhibit nitrogen fixation by cyanobacteria in coastal waters. In contrast, Tang et al. show that nitrogen fixation in a coastal cyanobacterium requires sodium ions and is apparently driven by sodium energetics and mixed-acid fermentation.

Corals and other marine invertebrates host diverse microbes that remain poorly characterized, especially in the deep sea. Here the authors discover a new clade of bacteria with uniquely streamlined genomes in the tissue of a deep-sea coral that provide insights into the genome reduction of symbionts.

A recent study reports the existence of a nitrogen-fixing organelle called the ‘nitroplast’.

A study on a marine bacterium shows that it can form multicellular aggregates, which enable division of labour.

This study describes how a marine cyanobacterium carries out nitrogen and carbon fixation at the same time.

This study shows that the application of probiotic bacteria to seaweed can protect from pathogen-induced bleaching.

This study shows that flagellate epibionts channel nutrient flows towards their large diatom host.
