A two-dimensional (2D) spectrofluorometer is often used to monitor various fermentation processes. The change in fluorescence intensities resulting from various combinations of excitation and emission wavelengths is investigated by using a spectra su

In mycelia cultivation, the moiphology of filamentous microorganisms changes greatly along with the cultivation time, which causes variations in mass transfer and metabolic behavior of the microorganisms. To give an insight into the morphology-associ

The goal of bioprocess-control and-scheduling is to maximize the profit of the whole process. Maximizing of the profit implies the optimal coordination among the subindices such as productivity, yield and quality of the product. These three subindice

Effective automated supervision can help to ensure the reliable operation of complex flow-injection analysis (FIA) systems. As an important element of a supervisory system, fast fault detection of the FIA systems is required. In this paper, a model-b

An on-line profit optimization approach for baker’s yeast continuous fermentation was developed. The profit optimization was done based on the process model system and profit function which were earlier established. An on-line rolling identificatio

Starting from the results of a morphologically detailed description of pellet development, a mathematical model is presented which is expected to yield equivalent results with substantially less computing expenditure. The simplification of the origin
