Benzylpenicillin(BP) inhibits bаcteriаl grоwth аnd is used fоr the preventiоn and elimination of bacterial contaminants in cell culture. Benzylpenicillin is acidic (pKa of 2.8). Optimal cell culture pH for mesenchymal stem cells (MSCs) is 7.3, but a pH of 6.9 strongly decreases the proliferation and expression of matrix proteins. Cell culture media is normally buffered by phosphate-buffer system. For the purpose of this problem, you may assume that phosphate has only one pKa of 7.2 (equation shown below) with an initial concentration of HPO4 - of 2.7x10-3 mol/L. What is the maximum amount of benzylpenicillin you can add to a 10L culture system (initial pH is 7.3) without negatively affecting MSC proliferation? Phosphate Buffer System: H2PO4 H+ + HPO4 -
