Chlorella ellipsoidea, culture medium, low-cost production, microalgae, wheat bran extract


Microalgae, Chlorella ellipsoidea is an excellent energy source for food and biofuel production. Nevertheless, the production cost of C. ellipsoidea using Bold's Basal Medium (BBM) is expensive, which led to the exploration of alternative low-cost medium for large-scale production. Low-cost fermented wheat bran extract medium (FWBEM), which has good nutritional properties, might be an alternative feedstock for mass production of C. ellipsoidea. The present study was conducted to evaluate the growth and production of C. ellipsoidea using different concentrations of FWBEM. Wheat bran was fermented at the concentration of 8.33, 6.66, and 5.00 g/L water labelled as T2, T3, and T4, respectively. The BBM was used as the control medium (T1). The growth and production of C. ellipsoidea were monitored for three days in terms of cell dry weight, specific growth rate, optical cell density, chlorophyll a content, and cell numbers. Those growth data revealed that C. ellipsoidea cultured at 6.66 g/L (T3) did not vary significantly with the standard inorganic BBM. However, T2 and T4 showed substantially lower cell growth and chlorophyll a content than control and T3. Compared to the BBM, a significant reduction in production cost was obtained in the FWBEM. Based on the cell biomass growth, pigmentation, and production cost,  FWBEM at a 6.66 g/L could be used as an alternative medium. Therefore, FWBEM has excellent potential to be used for the low-cost production of C. ellipsoidea.
