This report presents the proceedings of the Biochemical Engineering Symposium held at Kansas State University, April 28, 1979. Since a number of the contributions will be published in detail elsewhere, only brief reports of each contribution are included here. Requests for further information on work at Iowa State University should be directed to Dr. Peter J. Reilly; at Colorado State University to Drs. V. G. Murphy and A. R. Moreira, and at Kansas State University to Drs. L. T. Fan and L. E. Erickson.
