Proceedings of the 13th Annual Biochemical Engineering Symposium

The symposium reported here was the thirteenth of a series devoted to talks by students on their biochemical engineering research. The first, third, fifth, ninth, and twelfth were at Kansas State University, the second and fourth were at the University of Nebraska–Lincoln, the sixth was in Kansas City and was hosted by Iowa State University, the seventh and tenth were at Iowa State, and the eighth and eleventh were at the University of Missouri–Columbia and Colorado State University, respectively. All symposia have been followed by proceedings edited by faculty of the host institution. Because final publication usually takes place elsewhere, papers here are brief, and often cover research in progress. ContentSequential Utilization of Mixed Sugars by Clostridium acetobutylicum, B.
