青岛海域大面积聚集漂浮浒苔的显微观测 总被引:4,自引:1,他引:3
对近期在青岛海域大面积聚集漂浮的浒苔(Enteromorpha prolifera (Muell)J.Ag)进行常规显微镜观察,发现细胞内存在大小约1μm的可动的颗粒状结构。分别采用鞭毛染色和扫描电镜观察的方法对其进行了初步研究,均未发现此颗粒状可动结构具有鞭毛。用透射电镜对浒苔细胞的超微结构特征进行了观察,显示浒苔细胞壁致密而厚,每个浒苔细胞有1个片状叶绿体,贴近于细胞壁分布,淀粉粒含量丰富,但依然未发现胞内颗粒状结构具有鞭毛。 相似文献

Flagella, the basic locomotive organ in algae, as well as bacteria and some cells of animals or high plants, would be damaged
in the well stirred mass culture due to the strong forces caused by the fast mixing impellers. The dynamic regeneration of
the flagella in deflagellatedDunaliella salina was studied microscopically by using a bench-top flat-bottom photobioreactor. The results showed that 90 minutes was necessary
for the repair of flagella, after which half of the cells became motile as their flagella generated within 120 minutes and
nearly all of the cells could swim freely within 180 minutes.
