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:
