Study on the Growth of Isochrysis galbana

The effects of nutrient factors of the culture solution, such as nitrogen, phosphorus, iron, silicon, carbon, vitamins B 1 and B 12 , on the growth of Isochrysis galbana were studied. Nitrogen, phosphorus, iron, silicon, vitamins B 1 and B 12 were defined as essential factors in the culture of Isochrysis galbana. The optimum formulation can be describe using the orthogonal experiment. It is an optimum formulation for the growth of Isochrysis galbana that NaNO 3 -N 7.5g/ m 3 , KH 2 PO 4 -P 0.5 g/m 3 , FeCL 3 -Fe 0.1 g/m 3 , NaSiO 3 -Si 0.2 g/m 3 , B 1 100 mg/m 3 and B 12 0.5 mg/m 3 ar e added to the natural sea water.
