摘要：The objectives of this study is to determine the decrease in heavy metal concentrations of Cd in the culture media and to determine the effect of Cd concentration on the growth of Chlorella vulgaris .This study used a completely randomized design with four treatments and three repititions.This treatment includes, K treatment (control), treatment Cd 1 (cadmium concentration addition 1 mg / L), treatment Cd 3 (cadmium concentration addition 3 mg / L) and treatment Cd 5 (cadmium concentration addition 5 mg / L).Each sample was analyzed by AAS.Data were analyzed by using analysis of variance that was continued by Duncan's test.The results of the analysis of metal concentrations decrease of Cd in the culture medium is Cd 5 (0.4494 mg / l), Cd 3 (0.4008 mg / l), Cd 1 (0.2658 mg / l), and K (0.1162 mg / l).The analysis result of F value of variance showed that Chlorella vulgaris gave highly significant effect in decreasing the concentration of Cd.Whereas the result of the growth of Chlorella vulgaris during culture is Cd 3 (1015.97 cells / ml), Cd 1 (769.70 cells / ml), Cd 5 (719.55 cells / ml), and K (668.21 cells / ml ).The result of analysis variance showed that the various concentrations of Cd gave significant effect on the growth of Chlorella vulgaris .The conclusion is that Chlorella vulgaris have ability as bioremediator cadmium with different concentrations, this is indicated by the reduced content of Cd in the culture medium.The ability of metal Cd can substitute Zn function in synthesizing enzyme carbonic anhydrase that causes maximal growing.
其他摘要：DECREASE IN THE CONCENTRATION OF HEAVY METAL CADMIUM (Cd) AND MICROALGAE chlorella vulgaris GROWTH ON CULTURE MEDIA ABSTRACT The objectives of this study is to determine the decrease in heavy metal concentrations of Cd in the culture media and to determine the effect of Cd concentration on the growth of Chlorella vulgaris . This study used a completely randomized design with four treatments and three repititions. This treatment includes, K treatment (control), treatment Cd 1 (cadmium concentration addition 1 mg / L), treatment Cd 3 (cadmium concentration addition 3 mg / L) and treatment Cd 5 (cadmium concentration addition 5 mg / L). Each sample was analyzed by AAS. Data were analyzed by using analysis of variance that was continued by Duncan's test. The results of the analysis of metal concentrations decrease of Cd in the culture medium is Cd 5 (0.4494 mg / l), Cd 3 (0.4008 mg / l), Cd 1 (0.2658 mg / l), and K (0.1162 mg / l). The analysis result of F value of variance showed that Chlorella vulgaris gave highly significant effect in decreasing the concentration of Cd. Whereas the result of the growth of Chlorella vulgaris during culture is Cd 3 (1015.97 cells / ml), Cd 1 (769.70 cells / ml), Cd 5 (719.55 cells / ml), and K (668.21 cells / ml ). The result of analysis variance showed that the various concentrations of Cd gave significant effect on the growth of Chlorella vulgaris . The conclusion is that Chlorella vulgaris have ability as bioremediator cadmium with different concentrations, this is indicated by the reduced content of Cd in the culture medium. The ability of metal Cd can substitute Zn function in synthesizing enzyme carbonic anhydrase that causes maximal growing. ?é?á
