based on repetitive branching caused by rotational intergrowths of single‐unit‐cell lamellae. The self‐pillared, meso‐ and microporous zeolite is an active and selective catalyst for sugar isomerization. High yields for the conversion of glucose into fructose and lactose to lactulose are demonstrated.
The invention concerns the production by microbiological process of oligopolysaccharides of biological interest. More particularly, the invention concerns a method for synthesizing in vivo the oligopolysaccharides by internalization of an exogenous precursor in growing bacterial cells expressing adequate modifying and glycosylating genes.

Die Erfindung betrifft ein Präparat zur Applikation von Wirkstoffen in Form kleinster, insbesondere mit einer membranartigen Hülle aus einer oder wenigen Lagen amphiphiler Moleküle bzw. mit einer amphiphilen Trägersubstanz versehenen Flüssigkeitströpfchen, insbesondere zum Transport des Wirkstoffes in und durch natürliche Barrieren und Konstriktionen wie Häute und dergleichen. Das Präparat weist einen Gehalt einer randaktiven Substanz auf, der bis zu 99 Mol.-% des Gehaltes dieser Substanz entspricht, durch den der Solubilisierungspunkt der Tröpfchen erreicht wird. Das Präparat eignet sich zur nichtinvasiven Verabreichung von Antidiabetica, insbesondere von Insulin. Die Erfindung betrifft außerdem ein Verfahren zur Herstellung solcher Präparate.

The following description sets forth a new process for the preparation of ≧98.5% pure crystalline lactulose from commercially available aqueous syrups having the following composition: 50-70% by weight of lactulose, 3-9% by weight of lactose, 3-14% by weight of galactose, 4-7% by weight of other carbohydrates, the total content of carbohydrates different from lactulose being of from 10% to 30%.
Lactoferrin tablets containing as the active ingredients lactoferrin and lactulose and having a horizontal hardness of at least 4 kg and a vertical hardness of at least 3 kg; and lactoferrin tablets containing as the active ingredients a microbial cell powder of at least one microorganism selected from among actic acid bacteria, lactoferrin and lactulose and having a horizontal hardness of at least 4 kg and a vertical hardness of at least 3 kg. These tablets can be produced by using the conventional tableting apparatuses and yet have high hardness. Thus they do not adhere to the inner wall of the oral cavity and have a favorable taste. Since no excessive tableting pressure is needed in the production process, moreover, these tablets can contain much viable cells of lactic acid bacteria, though they are in the form of rigid tablet.
