Hybridoma cells were adapted in media containing up to 80 mM $K^+$. The adapted cells obtained tolerance at high osmotic pressure and low pH. The adapted cells showed a maximum viable cell density of $1.1{\times}10^6$ cells/ml when a batch culture was progressed in a nutrient-fortified medium with Erlenmeyer flask at 450 $mOsm/kgH_2O,$ as compared to $4.8{\times}10^5$ cells/ml for non-adapted cells grown under the same conditions. The adapted cells also showed a maximum viable cell density of $7.8{\times}10^5$ cells/ml with the same method at initial pH 7.0 as compared to $5.3{\times}10^5$ cells/ml for non-adapted cells. Adaptation of animal cells at high $K^+$ levels may therefore lead to an improvement of their performance at limited conditions.
