This project was part of a collaboration at @miamirosenstiel.bsky.social during my PhD between the @delcampolab.bsky.social and Grosell Lab. Thanks to all co-authors: Tristan Kravitz, @rociomozo.bsky.social, @lydeejeanne.bsky.social, Rachael M. Heuer, Martin Grosell, and @fonamental.bsky.social!

We hypothesize that CaCO3 precipitation in marine fish may not solely be a host-driven process, but potentially the result of a functional symbiosis with gut-associated Vibrio bacteria, expanding the role of symbiosis in marine biomineralization and global biogeochemical cycles.

New Discovery Report in PLOS Biology (@plosbiology.org)! Here we provide evidence that symbiotic bacteria within fish guts may play an important and overlooked role in the oceanic carbon cycle! doi.org/10.1371/jour... #MicroSky #SymbioSky #MicrobiomeSky

Marine fish produce CaCO3 precipitates ("ichthyocarbonates") in their guts as part of their osmoregulation strategy. Through this, fish may generate up to 9.04 Pg of new CaCO₃ annually, rivaling coccolithophores and pelagic foraminifera in global carbonate production. (Photo: Joshua Prezant)

We identified a high abundance of vibrios associated with ichthyocarbonates with the metabolic potential for CaCO3 precipitation. Specifically, we observe the expression of ureR by Photobacterium damselae subsp. damselae, which can induce the precipitation of CaCO3 via the production of bicarbonate!
