ASSESSMENT OF ALGAL CULTURE AND ELECTRICAL OUTPUT:
After 50 mL of highly concentrated algae culture was obtained, it was immediately transferred to a 500 mL nutrient rich bioreactor medium composed of an initial 2 mg of All-Purpose growth media (1 mg/250ml). Cell concentration, pH, aquatic temperature, salinity, sterilization, and lux levels were assessed. Cell concentrations were obtained with a spectrophotometer. After two days of cultivation, the algae was transferred to a 450 mL MFC anode chamber. Electrical testing was executed with a multimeter. After all conditions and parameters were assessed in the anode and cathode chambers, cell concentration was maintained at a stationary phase in each algal culture bioreactor. Photosynthetic absorption levels served as the magnitude and benchmark of electrical production. The indirect correlation between absorption levels and electrical output were further investigated as a proportional increase from the stationary phase. Due to the proliferative nature of the stationary development, optimal electrical output (mW) were highly expected. The following photometric absorbance rates presented the most efficiency:
