“conversion of corn ethanol waste to value-added …
TRANSCRIPT
Background• 94% of ethanol is produced from
corn
• Corn ethanol used in gasoline
• Becoming a more viable alternative energy
• Corn ethanol refineries produce waste stillage
Purpose• Measure the efficacy of
Chlorella Vulgaris as a
means of stillage
treatment
• Determine the best
conditions for stillage
removal and biomass
growth
• Use C. vulgaris as a food
source for crayfish
Characterization of the Data
μ = ln (α2/α1)/ (t2 − t1)
For Biomass Growth
For Nutrient Uptake
Specific Growth Rate (μ): Biomass Productivity (P):
P = (Xi - X0) / ti
R.E = (Ci - Cn) / Ci * 100
Removal Efficiency, R.E. (%): Elimination Capacity, E.C:
E.C = (Ci - Cn) / tn-i
