摘要
选择二种微藻分别在30%重水和普通水培养液中培养,测定其生长、荧光动力学和低温荧光发射光谱的变化。生长数据结果表明,卵形藻和斜生栅藻在重水中活性增加,生长得到促进,荧光动力学数据与生长数据一致。低温荧光发射光谱数据表明,30%重水抑制光系统Ⅰ的活性比光系统Ⅱ更为明显。
In order to find new way to treat the radioactive tritium waste water, scenedesmus algae and cocconeis algae are cultured in medium which contains 30% ( w ) deuterium water. During different time, activities of photosymthesis, absorption spectrum, growth rate and low temperature fluorescence spectrum are measured. Accelerated growth is found in the deuterium water compared to the normal water. Activities of photosnythesis show the similar result ( F v/ F m) to the growth data. It is also concluded from low temperature fluorescence spectra that algae activities in the deuterium water, which are expressed by PSⅠ/PSⅡ,are more sensitive than those in the normal water.
