This report presents the proceedings of the Biochemical Engineering Symposium held at Kansas State University, April 26, 1975. Since a number of the contributions will be published in detail elsewhere, only brief summaries of each contribution are included here. Requests for additional information on projects conducted at Iowa State University should be directed to Dr. Peter J. Reilly, and those at Kansas State University to the editors.
