The effects of different concentration of salinities on the biochemical components and growth rate of single cell microalgae, Tetraselmis chuii

Abstract

In This study Growth rate and biochemical components including carbohydrate, chlorophyll a and b and carotenoids of microalgae, Tetraselmis chuii, was studied in different concentration of salinities. Three levels of salinities (10, 27 and 40) with three replicates were used. The results of the treatments indicated that maximum of growth rate was observed in 10psu salinity with 2.8×106 ±0.38×105 cell per milliliters and minimum in 40psu with 1.6×106 ±0.48×105 cell per milliliters (P<0.05). The carbohydrate, chlorophyll a and b and carotenoid pigments were lower and significantly difference in 27psu and 40psu of salinities (P<0.05). Obtained results of cell concentration with 2.2×106 ± 0.45×105 per milliliters and biochemical components showed that the best salinity was 27psu for culture of microalgae, Tetraselmis chuii.
