Nathalie Dubois Calero offered a 2-part microalgae workshop for BioLab members on August 15th and September 11th. In the first part of the workshop, we covered DIY pigment extraction (chlorophyll, β-Carotene etc.) and paper chromatography using everyday solvents. In the second part, we explored how to maintain short and long term microalgae cultures by creating your own freshwater and saltwater media.
