| 英文摘要 | To confirm the effect of hypersaline shock on the growth of Dunaliella salina, the rapid light curves and chlorophyll fluorescence in D. salina with a NaCl upshift from 80 to 160, 240 and 320 g center dot L-1, respectively, were measured. Results showed that the photosynthetical saturated light of Dunaliella salina was downregulated to deal effectively with the severe NaCl increase from 80 to 160, 240 and 320 g center dot L-1. Dunaliella salina can deal effectively with the cells' rapid increase in NaCl from 80 to 160 g center dot L-1 by heat dissipation to dissipate the excess energy. Salinity with 240-320 g center dot L-1 NaCl led to overproduction of Q(A)(-) and the destruction of the PSII acceptor side, causing inhibition of photosynthetic electron transport. Dunaliella salina can also manage the abrupt rise in NaCl concentration from 80 to 240 g center dot L-1 by accumulating the amount of beta-carotene and glycerol per cell. However, Dunaliella salina cannot effectively manage the rapid increase in NaCl from 80 to 320 g center dot L-1 due to the stronger inhibition and impaired of the PSII acceptor side. It is suitable to shade D. salina cells to 500 and 800 mu mol center dot m(-2)center dot s(-1) when cells are exposed to a severe NaCl shift from 80 to 160 g center dot L-1 and 80 to 240 g center dot L-1. NaCl ranged from 80 to 240 g center dot L-1 favoured the growth and carotenoid content of D. salina; however, the survival rate and photosynthetic activity were lowered by the sudden increase in NaCl. |
