Preliminary Conjectures:
The hypotheses of the experimental trials is most associated with the scalability of Algae in combination with traditional MFC systems. Furthermore, the project explores the effectiveness of Algal culture as a sustainable substitute in small-large scale energy needs. The magnitude of a photosynthetic MFC is investigated by considering the potential electrical output and effectiveness of each Algal culture. Additionally, assessing the current provided understanding of the physical and biomolecular behaviors of each Algal genus is necessary (Chlorella Vulgaris, Spirulina, and Nannochloropsis ) to hypothesize the magnitude of energy efficiency. As noted in the literature review, preliminary research indicates that Algal cultures cultivate at significantly distinct rates, in terms of cell concentration and reproductivity. Algae cultures, such as Spirulina, Chlorella Vulgaris, and Nannochloropsis were the prime candidates for MFC experimentation due to their notably high culture densities. Algal cells have high frequencies of cellular respiration and photosynthesis that are critical in MFC efficiency. The respiratory processes of an algae bioreactor enable high density algal growth, which occurs exponentially. Although an algae growth curve is S-selected, exponential growth occurred most commonly when approaching the stationary phase. Since algae cultures mimic similar exponential growth curves to that of aerobic and anaerobic bacteria, the following conjectures were formulated:
