Abstract

D. salina is a unicellular alga with two flagella. This organism belongs to volvocales. In these studies two strains of D. salina were chosen. One of the strains isolated from the NAMAKDAN MOUNTAIN in GHESHM Island and designated as strain A, the second strain obtained from center of Marine Biotechnology, Baltimore, Maryland U.S.A and designated as strain B. Jhonson culture medium was used for all the treatment with slight modification at pH 7.5. All the parameters kept constant for GLYCEROL production except Nacl concentration. The GLYCEROL production with both the strains at Nacl concentration of 0.5, 1, 1.5, 2, 2.5, 3 and 3.5 molar checked at 7th (log phase), 16 th (end of log phase) and 25th day (stationary phase) of growth rate. GLYCEROL was usually assayed as a diol after oxidation with period ate. In each algal treatment the total, extracellular and intracellular GLYCEROL and intracellular GLYCEROL in cell obtained. The maximum production obtained at the end of log phase or beginning stationary phase. A Unbar line obtained between extracellular Nacl concentration and intracellular GLYCEROL in each cell. The maximum GLYCEROL was produced by strain B was 453.9 mg/ml whereas 431.7mg/ml GLYCEROL produced in strain A. (There is accord between Nacl concentration for the optimum growth and the maximum GLYCEROL production in strain B). The optimum Nacl concentration in strain B was 1.5 molar. This accord was not observed in type A, where there was a difference of 1 molar between Nacl concentration for the optimum growth and the maximum GLYCEROL production. Depicted results showed that strain B is a better candidate for GLYCEROL production. Intracellular GLYCEROL extracted.
