Proceedings of the Twelfth Annual Biochemical Engineering Symposium

This work presents the proceedings of the twelfth symposium which was held at Kansas State University on April 24, 1982. Since a number of the contributions will be published in detail elsewhere, only brief reports are included here. Some of the reports describe current progress with respect to ongoing projects. Requests for further information should be directed to Dr. Peter Reilly at Iowa State University, Dr. V. G. Murphy at Colorado State University, Dr. Rakesh Bajpai at University of Missouri, Dr. Ed Clausen at University of Arkansas, Dr. L. T. Fan and Dr. L. E. Erickson at Kansas State University.
