The cultivation of animal cells at controlled dissolved oxygen partial pressure. Reprinted from Biotechnology and Bioengineering Vol. X, Issue 6, Pages 801-814 (1968).
A 3-liter culture vessel has been developed for the growth of animal cells in suspension at controlled pH and dissolved oxygen partial pressure (pO(2)). The culture technique allows metabolically produced CO(2) to be measured; provision can be made to control the dissolved CO(2) partial pressure. In cultures containing a low serum concentration, gas sparging to control pO(2) was found to cause cell damage. This could be prevented by increasing the serum concentration to 10%, or by adding 0.02% of the surface-active polymer Pluronic F68. The growth of mouse LS cells in batch culture without pO(2) control was found to be limited by the availability of oxygen. Maximum viable cell populations were obtained when dissolved pO(2) was controlled at values within the range 40-100 mm Hg.
