ACKNOWLEDGEMENTS
Dr. Richard R. Dague was my mentor and friend during the first 2.5 years of research
at Iowa State University. I will always be thankful to him for giving me a chance to invent,
which was a childhood dream. It was not easy to continue my research after Dr. Dague died
in October of 1996, but I finished my degree and did not bail out before completion, as
promised. Dr. Dague not only taught me scientific knowledge. I learned, for example, how
to communicate in public, as Dr. Dague was an excellent speaker, and I learned how to
capitalize on new and innovative ideas (and how not to after he died).
Dr. Dague had worked together with several organizations and businesses to develop
full-scale applications of the invented technologies. Intriguingly, some people in these
organizations and businesses were not afraid in changing concepts into their "own"
technologies shortly after Dr. Dague's death. Consequently, Dr. Shihwu Sung, who
succeeded and continued Dr. Dague's work, was bound to have a hard time. Therefore, I
want to thank him for becoming my major professor and supporting my research and ideas.
Hopefully, we can work together some more in the future.
I would also like to thank the committee members for their time and input in this
research. These members are Dr. Timothy G. Ellis, CCE, Dr. Say K. Ong, CCE, Dr. Thomas
E. Loynachan, Agronomy, and Dr. James A. Thomas, B«&B. Also, thanks to all colleagues in
the lab who came and have graduate during my stay in Ames. A spjecial thanks goes to two
Master's students, who I partly supervised in their research efforts, Jim Flamming and
Sumate Chaiprapat. For their hard-working and always "want to improve" philosophy, made
the research in our lab better. Moreover, special thanks goes to Ben and Carol Riley for
proof reading my manuscripts.
Last but not least, I want to acknowledge ISU's professional stziff for their help in
several projects: Sharon Ferris, Gladys Sickau, Fern Parrish, Georgia Parham, Kathy
Petersen, Denise and Doug Wood, Pat Shafer, Chris Shieffer, etc., some whom are still
working in the CCE department and some who have moved on; A1 White, Jim Gaunt, and
Dave Schoeller of ASL; Tront Forre of the Chemistry Glass Shop; Dick Egger of the
Chemistry Machine Shop; Tracy Pepper and Bruce Wagner of the Botany Bessey
Microscopy Facility; and Warren Straszheim of the CCE Material Analysis Research Lab.
Running anaerobic reactors is time-consuming and takes lots of baby-sitting skills.
Lab visits become a way of living, which will ultimately not only influence your own life,
but also your partner's life.
