[The study of fermentation liquid's absorption spectra in elastase fermentation].
The present article studied the fermentation liquid's absorption spectra, bacteria growth period and elastase' production in elastase fermentation, and compared and analyzed the their relation. The results show that the changes in the absorption spectra were closely related with bacteria growth and elastase' production. The UV spectroscopic technique is helpful for detecting the change of the organic nitrogen base and enzyme. The study offers a new method to detect fermentation process and is basic for detecting fermentation process on line by UV spectroscopic technique.
