Abstract

The application of near infrared spectroscopy (NIRS) for in-process and quality control of fermentative production of L-lysine and L-threonine in industrial scale is presented. NIRS is a helpful tool for predicting optical density, ammonia, L-threonine and L-lysine in fermentation broth. For dry and solid product, Biolys®60, NIRS is suitable to give a quick estimation of L-lysine and water content.
