Abstract: C. glutamicum strains express modified gluconate repressor proteins GntR1 and GntR2. The C. glutamicum strains have an increased ability to produce L-lysine compared with an ability of a wildtype strain. The gluconate repressor protein GntR1 includes an amino acid sequence of SEQ ID NO: 9, where the amino acid Arg in position 102 is replaced by the amino acid Glu. The gluconate repressor protein GntR2 includes SEQ ID NO: 10, and its activity is attenuated compared to the activity of the GntR2 repressor protein of the wild-type strain. A method is developed for the fermentative production of L-lysine using such C. glutamicum strains.

The CLP can be purified after incubation.

Abstract: A process for producing polyacrylate particles by way of suspension polymerization and subsequent agglomeration can be performed. It was based on the problem of specifying a process for producing polyacrylate particles having defined shape and size, which enables improved heat management and requires a minimum amount of organic substances. Mechanical operating steps for establishing the shape and size of the particles—especially grinding and sieving—are to be avoided in order to produce a minimum amount of undersize. Finally, it is possible to implement the process economically on an industrial scale. An essential aspect of the process is that the steps of polymerization and agglomeration are conducted in separate apparatuses, namely suspension polymerization in a continuously operated capillary reactor and agglomeration in a batchwise reactor. The use of microstructured apparatuses is also possible.

Abstract: The present invention relates to a computer-implemented method for predicting a property value of interest in a sample investigated by infrared spectroscopy. The method aims at generating a calibration function. To this end, a set of calibration samples is selected, whereby outliers are identified and removed from the set of calibration samples. Outliers are determined using principal component analysis and singular value decomposition. The threshold value separating outliers from the remaining samples is calculated on the basis of a predetermined formulae. The threshold value may also be increased stepwise in order to dynamically set the threshold value, which is preferable for spectroscopic devices not operated under laboratory conditions.
