Abstract: | 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 deflagellated Dunaliella 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. |
