Are Diverse Algae more Efficient at Caputring Light Spectrum and Converting it to Algae Biofuel Purposes?

Developing an alternative to fossil fuel as a source of energy is a pressing issue. Microscopic algae can generate more biofuel on less land than terrestrial plants, but a number of challenges impede the commercialization of algae biofuel. One way to increase the yield of algae biofuel is to reduce losses of algae to pathogen and grazers. Diverse species may be more efficient at capturing and converting resources into biomass than any single species. I propose work aimed at studying the effects of algal diversity on the absorption of the light energy spectrum for the production of biofuel. We will test multiple species of algae, compare tradeoffs that constrain performances, and apply ecological theory in our experiments. I will investigate the differences in the absorption of wavelengths among monocultures and different combinations of polycultures. If the light spectrum is an important axis for niche partitioning, then algae species in monoculture should absorb a narrower portion of the wavelength spectrum compared to a diverse community of algae. Algae are a leading contender as a potential alternative source of energy to fossil fuel. My work will study the role of diversity in the intensifying of yield in algae production to maximize land and resources used.
