Chemostat Run
Chemostat Run


Looks like hit SS @ ~15,000 cells in the reactor volume (10nL). This is 1.5*10^9 cells/ml.

Sortostat Image Processing

Experiment on 6/9 to 6/13/05

Experimental Conditions

Chemostat Operating Conditions

  • Same as 6/7 experiment.
    • Except dilution rate varied from D=0.3 to 0.6 and the min pump period for D=0.6 was set to 50s. Cleaning period and sorting period varied for each dilution rate.

Results


Darker lines are moving average with 10 time point window.

Looked pretty good. Probably should have left longer at D=0.5 (first time) to see where the SS was exactly since it looks like the cell count may still have been decreasing. Cell counts were determined by processing of FL images as shown here.
