Advanced oxidation using UV radiation in the presence of H2O2 was applied for decolorization of liquid fertilizer and the resulting liquid fertilizer was utilized to the cultivation of microalga Chlorella vulgaris and biodiesel production. The growth of C. vulgaris was enhanced in decolorized medium. The biomass productivity of C. vulgaris in AOP-treated PAL1 reached 124 mg/L, which was 2.1 times higher than that in original PAL1, 58 mg/L/d. Cellular lipid accumulation was increased in decolorized medium (from 6 to 30%), because fast growing cells consumed nitrogren faster in decolorized medium and thus lipid synthesis was triggerred in nitroge-deficient environment. |
