The Effectiveness of a 3D Printed Hydrogel Membrane to Sustain Algal Growth

submitted on 25.06.2020, 18:24 and posted on 26.06.2020, 12:31 by Ben Caroway, Satchel Malo, Frank Parsons
This experiment assessed whether the photosynthetic algae species Chlorella Vulgaris could growth within a carrageenan based hydrogel. This hydrogel variant was synthesized with a nanosilicate powder, used to strengthen the polymer bonds between the carrageenan which allows for more robust 3D printing. Using a chip hemocytometer, it was found that Chlorella Vulgaris showed signs of growth in the carrageenan hydrogel without the aid of additional nutrients.
This means that the algae could potentially be 3D printed into structures used for biofiltration of enviromental pollutants
