Abstract
Microalgae species have been widely used as an alternative source for pigment extraction. The genus Dunaliella has been commercially cultured for its carotenoid pigments. Carotenoid is one of the commercially important pigments widely used in various industries. In the present study different salinities such as 0.3 0.5 0.7 and 0.9M were used to culture Dunaliella salina (Dunal) Teodoresco 1905 to determine the ideal salinity for the growth and carotenoid production for 12 days. Growth was monitored daily with respect to cell density. Carotenoids were extracted from samples every alternate day. Results showed that Dunaliella salina had highest (P 0.05) cell density when cultured at 0.7M salinity compared to other salinities. Similarly specific growth rate (0.53 .day-) and carotenoid contents (5.015mg.L-) were found highest (P 0.05) at 0.7M salinity compared to the other salinities. This study illustrated that Dunaliella salina favoured moderately high salinities (0.7M) for optimum cell growth and the production of carotenoid.
