富钒酵母对多刺裸腹蚤的生物学效应

Biological Effect of Vanadium-enriched Yeast on Moina macrocpa

摘要:

本文研究了富钒酵母对多刺裸腹蚤的寿命、存活率和生殖量的影响。结果表明: 不同钒浓度下富钒酵母组多刺裸腹蚤的平均寿命均长于相对应的无机钒组多刺裸腹蚤, 在相同钒浓度下, 富钒酵母和无机钒对多刺裸腹蚤的存活率和生殖量的影响差异更大, 富钒酵母比无机钒对多刺裸腹蚤的毒性要低。

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.
