Computer-aided fieldwork and training for typical biotechnology processes I. Building up of mathematical models

It is urgent needed now to apply computer science such as computer aided design(CAD) and computer aided operation(CAO) so as to promote biotechnology and bioengineering forward. A reliable,semi mechanismic,mathematical system model for L alanine production by biotechnology was established .The models were used as basic modules of a software which was applied to computer aided fieldwork and training. The values simulated from the system model agree well with the results of the commercial production.
