碩士 / 國立中興大學 / 植物學系 / 83 / By using the regular light-dark transition to make Chlorella
sp. strain DT (DT) and strain 211-8b (8b) acheive the
synchronous cell cycle. After desiccation,the total amount of
amino acids of both strains decreased, but the amount of DT was
always higher than that of 8b. The total amount of free poly-
amines in the clells of DT and 8b increased in coordination
with the cells during the cell cycle, until the 20th hour
reached the heighest amount. The cells of DT in every stage
were dried 2 hours at 30℃, then dried 1 hour at 42℃, it was
found that the total amount of polyamines in DT cells
increased, especially the cell of the 20th hour, the total
amount of polyamines increased 10.7 times more than which in
untreatment cells. And the cells of 8b in every stage were
applied the same treatment, the total amount of polyamines in
cells was decreased. However, at the 20th hour, the amount of
polyamines increased two times comparison of other stages. But
the increasement of 8b was far less than which of DT. After
dried DT cells with higher temperature at 60℃, the total
amount of polyamines decreased. Therefore we assumed that the
accumulation of polyamines after drying treatment is possibly
related to the osmoregulation of cell in desiccation.
