Research efforts focus on the areas of bioprocess modeling, modification, automation and control. A series of projects concerned with seafood and aquaculture processing systems, and in vitro plant tissue production are currently underway.

Seafood and Aquaculture Processing Systems

Commercial seafood and aquaculture processing industries, which play an important economic role in the United States, are currently poised to enter a period of rapid growth and change. Consumers are demanding increasing access to these products at a reasonable price. However, they are acutely aware of safety concerns associated with them. The combination of these factors and proposed HACCP based FDA inspection regulations have created a critical need to examine current processing systems and redesign them using newly developing sensing and automation technologies. Through these efforts, processors will have the ability to produce the best product possible at a reasonable cost.

A series of projects are currently under way in this area. They include:

In Vitro Plant Tissue Production

One of the first fields of plant biotechnology to reach commercialization was micropropagation. Industrial protocols, however, are primarily an extension of research laboratory procedures with minimal accomodations for large scale applications and process optimization. Significant obstacles exist which hamper further commercialization, the most important being costs. Costs must be decreased before further industry growth can occur. Production laboratories in possession of new technologies which significantly reduce expenses will quickly emerge as industry leaders. Unlike plants produced in vivo, the benefits from customization of the in vitro environment in response to measures of plant quality have not been investigated.

Research is underway to explore techniques for optimizing the micropropagation process by monitoring explant quality under in vitro conditions and using the information obtained to streamline the culture process. The expected result is the development of new propagation techniques which improve explant quality and accelerate growth rates.
