Proceedings of the Twentieth Annual Biochemical Engineering Symposium

The 20th Annual Biochemical Engineering Symposium was held at Kansas State University on April 21,1990. The objectives of the symposium were to provide: (i) a forum for informal discussion of biochemical engineering research being conducted at the participating institutions and (ii) an opportunity for students to present and publish their work. Twenty-eight papers presented at the symposium are included in this proceedings. Some of the papers describe the progress of ongoing projects, and others contain the results of completed projects. Only brief summaries are given of the papers that will be published in full elsewhere. The program of the symposium and a list of the participants are included in the proceedings.

Proceedings of the 23rd Annual Biochemical Engineering Symposium

The 23rd Annual Biochemical Engineering Symposium was held at the University of Oklahoma on April 17, 1993. The objectives of the symposium were to provide 1) a forum for informal discussion of biochemical engineering research being carried at the participating universities and 2) an opportunity for students to present and publish their work. Thirteen papers presented at the symposium are included in the proceedings. Because final publication usually takes place in refereed journals, the articles included here are typically brief and often cover work in progress. The program of the symposium and a list of participants are included in the proceedings. ContentsA Low-Cost Bioreactor Strategy for RNA Synthesis, H. Anthony Marble, Eleni Chrisikos, and Robert H.
