Abstract


This study aims to find out : (1) whether the addition of Mg2+ can support the nutrient in growth medium in the production of chlorophyll and protein by phytoplankton P. Cruentum and T. Chuii (2) in what concentration Mg2+ ions can work optimally and (3) what functional group plays a role in the influx of Mg2+ into the cells of phytoplankton P. cruentum and T. chuii.

The result reveal that the addition of Mg2+ nutrients in P. Cruentum and T.chuii can support  the nutrients in the growth medium.

The optimum concentration of Mg2+ nutrient in the production of chlorophyll and protein by P. Cruentum is 40 ppm (the amount of chlorophyll and protein is 780.000 mg/m3 and 316.0025 ppm). The optimum concentration of Mg2+ nutrient in the production of chlorophyll and protein by T. chuii is at 40 and 20 ppm (the amount of chlorophyll and protein is 27651.04 mg/m3 and 240.8483 ppm).

The functional groups involved in the process of nutrient influx of Mg2+ into P. cruentum and T. chuii are M-S and N-H (for P.cruentum) MX and C-CI (for T. Chuii).
