Abstract
|
|
|
|
The characteristic of Cyanophyte genus SG63 is similar to that of Aphanot hece sp. The optimal growth was found with the concentration of NaCl and MgSO_4·7H_2O on the culture medium. The most optimal condition is 56‰of NaCl (S4 medium) and 20‰of MgSO_4·7H_2O (M2 medium). The synthesis of chorophyll α, phycocyanin and soluble proteins is affected by the concentration of the two mineral elements in culture. Especially, the content of chlorophyll α and phycocyanin decreases on the most highly saline medium. The identified principal carotenoids are β-carotene, echinenone, zeaxanthin and myxoxanthophyll. The rates of concentration of protein/chlorophyll α and phycocyanin/chlorophyll α are low on the S4 medium. Inversely, these rates are the highest on the M2 medium. Accordingly, the high concentration of MgSO_4·7H_2O provoke the synthesis of phycocyanin and total proteins.
