Process monitoring of an industrial fed‐batch fermentation [PDF]

Biotechnology and Bioengineering, 2001
AbstractMarket demand places great emphasis in industry on product quality. Consequently, process monitoring and control have become important aspects of systems engineering. In this article we detail the results of a 2‐year study focusing on the development of a condition monitoring system for a fed‐batch fermentation system operated by Biochemie Gmbh

Fed-Batch System for Propagation of Brewer’s Yeast [PDF]

Journal of the American Society of Brewing Chemists, 2021
A novel high-density yeast propagation system has been developed, which produced yeast that performed as well as cropped yeast in commercial brewery trials. This process is capable of producing yeast concentrations 13 times greater than traditional yeast propagation approaches used in breweries to date.

Metabolic Control in Mammalian Fed-Batch Cell Cultures for Reduced Lactic Acid Accumulation and Improved Process Robustness

Bioengineering, 2016
Biomass and cell-specific metabolic rates usually change dynamically over time, making the “feed according to need” strategy difficult to realize in a commercial fed-batch process.
