Abstract :Microalgae are known as a source of valuable biomolecules which are used in various industrial fields such as aquaculture, food, feed, pharmaceuticals, bio-fertilizers and bioenergy. Chlorella sp. is one of the common microalgae, cultured in the world. In this study, it was examined that growth and pigments of Chlorella sp. in lab-scale tubular photobioreactor at indoor conditions. Highest cell number and highest specific growth rate were determined as 155 x 106 cells.mL-1 and 0.79, respectively. Highest dry weight was measured as 4.19±0.059 g.L-1 and mean dry weight was found as 3.56±0.079 g.L-1. Highest chlorophyll a amount was found at 40th day as 106.7±0.079 µg.mL-1. Highest carotenoids was 15.87±0.033 µg.mL-1 at the day 22. Also, 983.8 gram of total biomass was collected in last 45 days, after the exponential phase. Study shows that indoor production of Chlorella sp. provided more reliable sustainability. As a results, Chlorella sp. is photoautotrophically producible at high amounts throughout the year.
