C. vulgaris JSC-6 can efficiently utilize nutrients and COD in
diluted swine wastewater for cell growth and carbohydrate accumulation,
with high COD (up to 76%) and nitrogen (up to 91%)
removal efficiencies. Using fivefold diluted wastewater for
microalgal growth gave the highest biomass concentration of up
to 3.96 g/L. Moreover, microalgal biomass grown on the wastewater
could accumulate 58% carbohydrate content. Glucose
accounted for over 90% of the total sugars in the microalgal carbohydrates.
The growth of carbohydrate-rich C. vulgaris JSC-6 on
swine wastewater was accompanied by the formation of EOM,
which may have adverse effects on microalgae-based wastewater
treatment.
