Abstract: Disclosed herein are methods for preparing modified starches, and uses thereof, and relates to the technical field of starch preparation; modifying a gelatinized starch suspension with ?-amylase; after inactivating the ?-amylase, further modifying with a branching enzyme, after inactivating the branching enzyme, further modifying with pullulanase, after inactivating the pullulanase, precipitating a resulting enzymatic hydrolysate with an alcohol to obtain precipitates; and drying the precipitates to obtain the modified starch. The methods disclosed a starch is modified remarkably, herein substantially increase the number of linear chains with a degree of polymerization DP6-11 in the starch chains and, thus, significantly increase the content of resistant starch in the modified starch—thereby facilitating the use in foods and medicaments.

Abstract: The present invention relates to the identification of a genomic integration site for heterologous polynucleotides in Chinese Hamster Ovary (CHO) cells resulting in high RNA and/or protein production. More specifically it relates to CHO cells comprising at least one heterologous polynucleotide stably integrated into the S100A gene cluster of the CHO genome and to methods for the production of said CHO cells. Further, the invention relates to a method for the production of a protein of interest using said CHO cell and to the use of said CHO cell for producing a protein of interest at high yield. Integration within these specific target regions leads to reliable, stable and high yielding production of an RNA and/or protein of interest, encoded by the heterologous polynucleotide.

Abstract: Methods for the production of L-glufosinate (also known as phosphinothricin or (S)-2-amino-4-(hydroxy(methyl)phosphonoyl)butanoic acid) are provided. The methods comprise a two-step process. The first step involves the oxidative deamination of D-glufosinate to PPO (2-oxo-4-(hydroxy(methyl)phosphinoyl)butyric acid). The second step involves the specific amination of PPO to L-glufosinate, using an amine group from one or more amine donors. By combining these two reactions, the proportion of L-glufosinate in a mixture of L-glufosinate and D-glufosinate can be substantially increased.
