Abstract |
Optimal culture conditions of wild Chl. ellipsoidea for tapioca alcohol distillation waste treatment were examined, and results obtained were as follows: For wild Chl. ellipsoidea culture organic medium was more effective than inorganic one. Optimal dilution for alcohol distillation waste treatment was three times. Optimal culture conditions were 6.0 of pH, 30℃ of temp., 8-10 Kilolux of light intensity, 1.0% of glucose, 0.2% of urea, 0.4% of KH₂PO₄ and 0.02% of MgSO₄-7H₂O concentration. Glucose should be added for three times diluted alcohol distillation waste treatment. BOD removal efficiency of alcohol distillation waste by Chl. ellipsoidea was 91% when inoculated of seed cultured in waste liquid and 87% when inoculated of seed cultured in waste liquid culture solution. |
