Abstract

This work aimed to study the effect of several environmental parameters (light intensity, temperature, and aeration rate) on the accumulation of nutritional components and lutein production in a green microalgae Chlorella sp. It was proven in this work that the biochemical composition of Chlorella sp. could be manipulated through the control of environmental conditions during the cultivation. A simple 2L bubble column photobioreactors installed in a well controlled culture chamber was employed as a model system where temperature, light intensity, and aeration rate (usg) could be controlled in the range from 30 - 40ºC, 10 - 30 kLux, and 0.5 - 1.5 cm/s, respectively. Lipid and protein productivity were the most abundant at 35°C, 10 kLux and 1 cm/s, whereas carbohydrate productivity was found to be maximized at 30°C, 30 kLux and 0.5 cm/s. In addition, Chlorella sp. could also generate strong antioxidizing agents like lutein which was found to be mostly produced at 35°C, 10 kLux and 1 cm/s.
