Abstract: 

A carbon source for the growth of micro-algae is essential, therefore, to increase the yield production, carbon supply is one of the most important steps in the development of micro-algae. In this study, the effect of sodium bicarbonate (NaHCO3) concentrations on Scenedesmus (Chlorophyta) growth was evaluated in TMRL (AG) medium. In this purpose, we studied the effects of the different sodium bicarbonate concentrations (2.5, 5, 7.5 and 10 ml) during 13 days. Results obtained of different concentrations sodium bicarbonate which added to the medium TMRL (AG), showed the maximum growth in the thirteenth day with 238×105 cells/ml at the third treatment of 7.5 ml concentration, when the different concentrations of sodium bicarbonate were added to TMRL (AG) medium. In T3 medium, Scenedesmus showed rapid grow as the growth rate and coefficient were calculated which are 1.56 and 0.11, respectively. According to the results, the use of sodium bicarbonate in normal and cheap TMRL (AG) medium modified for mass production of micro algae Scenedesmus is recommended.
