Diatoms are an essential element of the food web of many aquatic ecosystems. However, seasonal algal blooms which occur as a result of anthropogenic contaminant loading can have severe impacts on human health, aquatic ecosystems, and the economy. Diatom blooms can be particularly harmful in water supply reservoirs, due to toxin production and filter blocking at water treatment works. Although their importance is commonly recognized, their behaviour is yet not fully understood. One open fundamental question is how these cells adapt to sudden changes in their physicochemical environment and evolve into harmful blooms.
Our group recently verified that the diatoms do in fact communicate via showing for the first time that electrical communication of cells can be recorded extracellularly by means of a unique measurement setup using low-impedance electrodes.
These findings open a new page in the understanding of algal signalling and enable novel sensing technologies to predict the development of algae blooms and of an extensive range of stress-induced alterations in the aquatic ecosystem. To develop a technology able to sense and predict the development of algae blooms and translate an extensive range of stress-induced alterations in the aquatic ecosystem this project will address the following objectives:
• Devise algae on a chip technology for microalgae monitoring • Characterise the signals from different types of microalgae and their reaction to stress conditions via mass spectrometry, impedance spectroscopy and noise
