Abstract:
The present invention relates to a method for culturing microalgae using sea water and, more particularly, to a method for culturing microalgae, which includes putting microalgae and a culture solution for culturing microalgae into a culture machine of a photobioreactor, allowing the photobioreactor on float in the sea water and be exposed to sunlight, and supplying carbon dioxide to the microalgae.

PURPOSE: A method for producing biomass using microalgae is provided to obtain biomass with high yield. CONSTITUTION: A method for producing biomass comprises the steps of: preparing a medium containing 200-240 mg/L of NaNO_3, 200-240 mg/L of KNO_3, 130-200 mg/L of P_2O_5, 50-100 mg/L of KH_2PO_4, 20-45 mg/L of MgSO_4·7H_2O, 25-45 mg/L of Mg(NO_3)_2·6H_2O, 50-100 mg/L of Ca(NO_3) _2, 25-45 mg/L of K_2SO_4, 20-45 mg/L of Na_2-EDTA·2H_2O, 0.5-1.5 mg/L of FeCl_3·6H_2O, 0.01-1.0 mg/L of Co(NO_3)·6H_2O, 0.01-1.0 mg/L of MnSO_4·5H_2O, 0.01-1.0 mg/L of ZnSO_4·7H_2O, 0.001-0.1 mg/L of CuSO_4·5H_2O, 0.001-0.1 mg/L of (NH_4) _6Mo_7O_24·4H_2O, and 0.01-1.0 mL/L of HNO_3; adjusting pH concentration to pH 9.0; and inoculating microalgae into the medium and culturing the microalgae.
Abstract:
The present invention relates to a production method of pigment using microalgae. The production method of the pigment using microalgae comprises the following steps: preparing a medium containing 200240 mg/L of NaNO3, 200-240 mg/L of KNO3, 130-200 mg/L of P2O5, 50-100 mg/L of KH2PO4, 20-45 mg/L of MgSO4·7H2O, 25-45 mg/L of Mg(NO3)2·6H2O, 50-100 mg/L of Ca(NO3)2, 25-45 mg/L of K2SO4, 20-45 mg/L of Na2-EDTA·2H2O, 0.5-1.5 mg/L of FeCl3·6H2O, 0.01-1.0 mg/L of Co(NO3)·6H2O, 0.01-1.0 mg/L of MnSO4·5H2O, 0.01-1.0 mg/L of ZnSO4·7H2O, 0.001-0.1 mg/L of CuSO4·5H2O, 0.001-0.1 mg/L of (NH4)6Mo7O24·4H2O, and 0.01-1.0 mL/L of HNO3; adjusting the pH of the medium into 7.50-8.75 using KOH, NaOH, or a mixture thereof; and injecting Haematococcus sp. KORDI03 (requisition number KCTC12348BP) to the medium, and culturing.
