Abstract

In this study investigation was made to evaluate the effects of different algal media components to get optimized cell count of Scenedesmus dimorphus. Five different fresh water algal media such as Bold’s Basal Medium (BBM), M4N medium, BG-11 medium, N-8 medium and M-8 medium were used for culturing S. dimorphus in flask culture. A set of environmental factors including light, temperature, air flow rate and nutritional components was standardized to obtain the highest productivity of 0.1406 g/L with specific growth rate of 0.10483/day. This study designates the bold basal medium as advantageous one for S. dimorphus and also reveals that production of metabolites by the same algal strain depends mostly on the nature of constituents of media and might have different influence on the pH.

 

Key words: Scenedesmus dimorphus, bold basal medium, algal growth.
