Abstract: 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.

Abstract: The present invention relates to the enrichment and detection of microorganisms which contaminate food products, especially beverages and soft-drinks. It is particularly suitable for the detection of beer-spoiling bacteria. The present invention provides a novel system which a) improves the recovery of spoilage microbes b) provides faster detection and earlier emergence of colonies on plates, and c) provides larger colony sizes which makes detection easier.

Abstract: The present invention provides a method for improving the preparation and use of growth media by the uses of specific pellet formulations, which especially are tablets of different sizes, which contain the growth medium or parts thereof and are sterilized with the standard methods of pharmaceutical technology. Specifically these pellet formulations are applied to control a cell culture in a way that the adaptation phase is shorter or that the growth is controlled by a release of certain components at a certain time and in a certain concentration during the process, and nutrients (e.g., nitrogen) can be packed into the cultivation vessel in amounts sufficient for high cell densities without the risk of intoxication of the organism.
