Abstract
(EN)
The present invention is generally in the field of continuous and high-cell-density cultivation in laboratory- or large-scale liquid shaken cultures. More particularly it relates to a method of enzyme-based fed-batch (EnBase) for liquid microbial prokaryotic or eukaryotic cell cultivation having the possibility to manipulate the growth rate of the cultured organisms by a controlled enzymatic release of the growth-limiting substrate-monomer from substrate-polymers or substrate-oligomers.
