Our review “Symbiotic Ammonia Oxidation in the Marine Environment” is now published in Annual Review of Marine Science and is fully open access.
We synthesise ammonia-oxidising microbes in marine symbioses, their implications, and key gaps in host-associated nitrogen cycling

Every opportunity politicians provide for you to tell them about how chronic underfunding of research in Australia is affecting your particular fields, people, working conditions etc. is extremely important.

New preprint!
We explore how gutless marine worms and their bacterial symbionts use organosulfur compounds like DMSP and DMS - key molecules in marine sulfur cycling.
Our results show that these compounds support carbon and energy metabolism in the Olavius algarvensis symbiosis.

NEW pub in @science.org 🥳

Is it sponges (panels A & B) or comb jellies (C & D) that root the animal tree of life?

Here, we show that deep below, corals and feather stars don’t just share space – they share microbes. Endozoicomonadaceae + Nitrosopumilaceae inhabit both hosts in a “promiscuous” symbiosis that may fuel nitrogen cycling in the deep sea.

New review out in Annual Review of Marine Science! 🌊🧫
We explore how ammonia-oxidising microbes form symbioses with marine hosts - fueling the nitrogen cycle, fixing carbon, and possibly feeding their hosts.

This looks like a great resource for drawing metabolic schemes and the proteins involved. Lost countless hours looking for the subcellular location of specific enzymes and very keen to give this a try

Keeping your symbiosis genes on a plasmid is a smart move if you have multiple potential hosts. Here a gut bacterial symbiont, but same is true for N-fixing Rhizobia.

A nice paper on microbial dark matter revealing that in situ devices increase coral's microbes culturability up to 570% is out on iScience 🧪. This device, initially used in soils, has proved to be useful in marine sponges and, now, in corals as well.
