โฆ Synopsis
Two bioprocess simulators, Aspen BPS TM and SuperPro Designer ยฎ , were used to simulate and compare two flowsheets for production of tissue plasminogen activator (t-PA) from Chinese hamster ovary (CHO) cells. The flowsheets were designed to compare the economics of using serum and serum-free medium in the bioreactor. The base case flowsheet used a medium with 10% serum while the alternative flowsheet used a serum-free medium.
Affinity chromatography was the major step in the downstream processing of the base case flowsheet. The alternate flowsheet was designed for two-step cell culture growth and production. Ion-exchange chromatography was considered sufficient for purification of the low protein medium for this case. At a price of US$ 25/l for serum-free medium, the alternate flowsheet was found to have an return on investment (ROI), of 115% compared to 65% for the base case flowsheet.

This paper is aimed at introducing computer simulation of extended defects in crystalline materials by means of empirical potentials. In this context we understand by large scale calculations those related to a number of atoms from 10 3 to 10 6 and/or a time scale of few nanoseconds (10 2 -10 4 ps)
