Biomass and contents of protein,âcarotene and soluble carbohydrate of Dunaliella salina under Oìg·L,3 ìg·L-1,12 ìg·L-1,50 ìg·L-1,200 ìg·L-1 and 800 ìg·L-1 of Cr3+ concentration were analysed.The results snowed that the lower level of Cr3+ could promote the growth of algae.When D.salina exposed to 50 and 200 ìg·L-1 of Cr3+ the algae contained protein 3.06% and 6.55% higher than the control respectively,and had higher biomass.The algae in the medium added 200 ìg·L-1 of Cr3+ resulted in âcarotene and soluble carbohydrate contents of 3.93% and 2.38% higher than the control respectively.In a conclusion a suitable dose of Cr3+ in medium stimulated Dunaliella salina to grow and improved the quality of nutrient such as protein,âcarotene and soluble carbohydrate.
