Applying neural networks as software sensors for enzyme engineering

摘要

The on-line control of enzyme-production processes is difficult, owing to the uncertainties typical of biological systems and to the lack of suitable on-line sensors for key process variables. For example, intelligent methods to predict the end point of fermentation could be of great economic value. Computer-assisted control based on artificial-neural-network models offers a novel solution in such situations. Well-trained feedforward--backpropagation neural networks can be used as software sensors in enzyme-process control, their performance can be affected by a number of factors.
