초록
The aim of this study was to investigate the application of Deep See Water(DSW) in S. platensis cultivation through the growth experiments, bio-kinetics factors(maximum specific growth rate, doubling time and yield) and production cost. Growth experiments was performed with S. platensis under various culture medium conditions (deep sea water + low cost medium). Growth tests for culture medium demonstrated that the deep sea water to low cost medium ratio of 25:75(W/W) was effective in S. platensis with the maximum biomass of 0.88 g/L and minimum medium making cost per production mass of 8.17 KRW/g. The parameter estimation of bio-kinetics (maximum growth rate and yield) for low cost medium results showed that the maximum growth rate, doubling time and yield of N, P, K was obtained under deep sea water to low cost medium ratio of 25:75(W/W) of 0.099 1/day, 3.007 day and 0.170, 0.029, 0.033, respectively.
