I research the bacteria present in fish gills, to elucidate the novel symbiotic relationships between nitrogen cycle bacteria and fish. I use molecular and microscopic techniques to study the fundamental aspects of the novel fish gill-bacterial symbiosis. In the project, we also investigate the impact of the symbiotic bacteria on the excretion of nitrogenous wastes (in the form of ammonia) by the fish.
- 2019 - 2023 Fish branchial nitrogen cycle symbionts: novel approaches towards sustainable aquaculture Knowledge of the mechanisms by which fish excrete their metabolic nitrogenous waste and insights into nitrogen cycling in aquaculture systems is of utmost importance to improve the sustainable commercial production of fish. In fish, most nitrogenous waste is excreted via the gills as ammonia, a potentially toxic nitrogenous compound. Previously it has been shown that the gills of fish harbor a unique combination of hitherto overlooked nitrogen-cycle microorganisms that can theoretically detoxify excreted ammonia by converting it into inert dinitrogen gas. By doing so, these microorganisms may benefit from the ammonia supply by the host and prevent the build-up of this compound to toxic concentrations. This novel relationship between vertebrates and microorganisms may shed new light on nitrogen handling by ammonotelic fish species and will be investigated in more detail within this project.
