Description

<p>To evaluate suitable salinity conditions for culturing Rhodomonas sp. (Hf-1 strain), the effect of different salinities on the growth and biochemical compositions were studied. A series of culture trials were carried out at five different salinity levels (7, 14, 21, 28, 35 psu) for a period of nine days to investigate the effects on algal growth, fatty acid composition, amount of protein and fatty acids by biochemical analyses. Regarding results, stable algal growths were observed in each salinity group, except at 7 psu. Moreover, among 14 to 35 psu groups, no significant differences were observed in the amount of essential fatty acids, EPA/DHA ratios, and protein contents. Based upon these results, it could be suggested that the present microalga can be cultured under a wide range of salinity conditions without impairing the high EPA and DHA contents and is suitable as a feed organism used in the seedling production of marine animals.</p>
