When 7% of the initial sugar concentration (w/v) decreased to 1%～2%, the sugar content in the culture was controlled at this level (1%～2%) by intermittent constant speed feeding (on the average of 23 g/L·h) throughout the fermentation.

A possibility to measure glucose concentration using a Michelson partial coherent interferometer (LCI) is presented.

And then the curve of glucose concentration is obtained.

The Basic Experimental Study on Floating-reference Method in Non-Invasive Sensing of Blood Glucose Concentration with Near-Infrared Spectroscopy;

The principle of the noninvasive blood glucose concentration measurement with floating-reference method was introduced.

The clinical problems for these technologies are discussed and analyzed,and the further direction of blood glucose concentration monitoring technology is overviewed as well.
