생물동역학 인자를 이용한 해양심층수기반 친환경 저비용 Spirulina platensis 배지 적용 가능성

Abstract

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.
