Abstract

The fresh water and nutrients are costly inputs in algal cultivation. Nowadays, marine algae are in focus since they can be cultivated in seawater with minimum freshwater addition. In this study, marine Chlorella sp. was characterized in lab and open ponds (1m²) of greenhouse to evaluate the potential of biomass production. In lab studies, the growth performances (OD and biomass production) of algae in industrial grade nutrient sources were found similar to lab grade sources. The growth at 12:12 h. of light: dark cycle was at par with 24 h. of continuous light illumination. The minimum inhibitory concentrations for hydrogen peroxide, benzalkonium chloride and sodium hypochlorite were determined to be 2.5, 5, and 5 mgL^-1 respectively. In pond studies, the strain was found to tolerate salinity up to 5.5%. Highest aerial, volumetric productivities and nutrient removal were observed at 10 cm as compared to 15 and 20 cm depths. The aerial productivities and biomass composition in semiturbidostat mode cultivation at various set OD’s of harvest were found comparable and semiturbidostat mode was found more productive than batch mode. Overall study shows that the marine Chlorella sp. is a robust strain and can be cultivated in open ponds using seawater.
