Proceedings of the Twenty-Fifth Annual Biochemical Engineering Symposium

The Annual Biochemical Engineering Symposium Series started in 1970 when Professors Larry E. Erickson (Kansas State University) and Peter J. Reilly (then with University of Nebraska-Lincoln) got together in Manhattan, KS along with their students for a half-day powwow and technical presentation by their students. Ever since then, it has been a forum for Biochemical Engineering students in the heartland of USA to present their research to their colleagues in the form of talks and posters. The institutions actively involved with this annual symposium include Colorado State University, Kansas State University, Iowa State University, University of Colorado, University of Kansas, University of Missouri-Columbia, and University of Oklahoma. The University of lowa and University of Nebraska-Lincoln have also participated in the conference in recent years. The host institutions for the different symposia have been: Kansas State University (1, 3, 5, 9, 12, 16, 20), Iowa State University (6, 7, 10, 13, 17, 22), University of Missouri-Columbia (8, 14, 19, 25), Colorado State University (II, 15, 21), University of Colorado (18, 24), University of Nebraska-Lincoln (2, 4), University of Oklahoma (23). The next symposium will be held at Kansas State University. Proceedings of the Symposium are edited by faculty of the host institution and include manuscripts written and submitted by the presenters (students). These often include works-in-progress and final publication usually takes place in refereed journals. ContentsPatrick C. Gilcrease and Vincent G. Murphy, Colorado State University.
