Oleaginous microalgae Chlorella vulgaris has been identified as potential algal species for biodiesel production. The information on behaviour of this alga under abiotic stress (pH, ambient temperature and photoperiod) and nutrient stress is limited. This study aimed to investigate the effect of pH (2, 5, 7, 9 and 11), temperature (10, 20, 30 and 40 °C), photoperiod (continuous light, 24:0 h; light and dark, 18:6 h; and continuous dark, 0:24 h) and nutrient load (N–NO3− and PO4−3) on growth and chemical composition of harvested biomass of Chlorella. Result indicates the optimum ranges of abiotic conditions as 18:6 h light/dark regimes (photoperiod), 7–9 pH and 20–30 °C temperature for algal cultivations.
