超声波对条斑紫菜硅藻附着症的作用

Effect of ultrasonic on diatom felt disease of Porphyra yezoesis

为使条斑紫菜(Porphyra yezoensis)上附着的硅藻脱落,从超声波的生物学效应出发提出了新的思路。选择生长状态较好的附着硅藻的紫菜分别在不同的输出功率和时间下用超声波处理。结果表明,当超声波的输出功率为300 W、处理时间25 s时,可以成功地去除附着的硅藻及黏质柄,而对条斑紫菜未产生不良影响。该研究结果在条斑紫菜的加工生产上有应用与推广价值。

We put forward a new method from the biologic effect of ultrasonic to make the epiphytic dia tom fall off. We found that epiphytic diatom can be successfully cleared when output power and treating time are respectively 300 W and 25 s, which have little harm to the growth of Porphyra yezoensis. The result is valuable to being applied and recommended in laver production.
