Biological Effect of Vanadium-enriched Yeast on Moina macrocpa

Abstract:

This paper reports a experiment which vanadium-enriched yeast affected on life-span, survival rate and reproduction quantity of moina macrocpa. The results indicated that the average life span of moina macrocpa of vanadium-enriched yeast group were all prolonged compared with inorganic vanadium group under different concentration of vanadium. As to same concentrations of vanadium, it is significant difference on survival rate and reproduction quantity of moina macrocpa between the group of vanadium-enriched yeast and inorganic vanadium. So it is concluded that the toxicity to moina macrocpa of vanadium-enriched yeast was lower than inorganic vanadium.

Key words:Vanadium-enriched yeast, Moina macrocpa, Life-span, Survival rate, Reproduction quantity
