A programmable microalgae cultivation platform for sustainable food production and waste resource recovery

The manipulation of gene activity in microalgae (cyanobacteria) offers the possibility of producing energy and materials directly from sunlight, water, and carbon dioxide, contributing directly to more holistic modes of food production, innovative bioproducts and reliable bioenergy solutions that reduce human carbon emissions. Despite their recognized potential, it has proven challenging to develop scalable genetic systems for industrial cyanobacterial strains. We are addressing this challenge, in collaboration with Purify, a local biotechnology company, using Arthrospira platensis (Spirulina). We will optimize Spirulina growth under a range of metal concentrations using a recently developed high-throughput lighting system at the University of British Columbia. Use of this lighting system will enable us to build a series of models describing optimal growth under a combination of different metal and media conditions, and isolate specific components that are essential for increased biomass yield or metal tolerance and recovery. We will use this combined platform to increase Spirulina carbon capture associated with nutraceutical or food production including overproduction of phycocyanin and selected cofactors with antioxidant or health promoting properties as well as potential applications in water treatment. Throughout this project we will work closely with Purify providing a path to market for the research while training highly qualified personnel primed for success in the emerging Canadian bioeconomy.
