Effects of Media Nutrients and Cultivation Conditions on Biomass Production of Freshwater Microalga Chlorella Vulgaris

Article excerpt

Background: Chlorella vulgaris is a freshwater microalga capable of accumulating high lipid content, possessing high growth rate, providing suitable fatty acid profile for biodiesel production and also it is widely cultivated with inexpensive nutrient regime.

Methods: In this study, the growth rate and biomass produc- tion of C. vulgaris were investigated under different culture media namely Bold Basal medium (BBM), Modified Bristol's medium (MBM), Blue green algae-11 medium (BG-11), Rudic medium and Zarrouk medium.

Results: Culture of C. vulgaris in Zarrouk medium caused higher growth rate and higher biomass production. In addi- tion, different cultivation modes, phototrophic (NaHCO3), photoheterotrophic (molasses) and mixotrophic (NaHCO3 and molasses) modes were examined to determine the effi- cient culture condition. …
