Table 1. Mathematically optimized procedures for addition and removal of 17 molal glycerol at 37°C.

Step Glycerol (mol/kg) Nonpermeating solute (Osm/kg) Time (min) Predicted Cell Yield
CPA Addition 1 0.83 0.08 12 70%
2 17 3.3 1
CPA Removal* 1 0 0.8 2 99%
2 0 0.4 10

* Several CPA removal procedures had nearly identical toxicity costs, making it difficult to identify the global optimum. The given procedure was selected from this group for experimental expediency.
