A method for the manufacture of products by biotechnological methods in bacterial cell culture is disclosed as well as products obtained, the use of certain additives to the media used in the manufacture of said products in bacterial cell culture media, and the use of said additives in reducing the detrimental effects of radicals in the manufacture of the products, as well as aspects related to these invention embodiments. The manufacturing process or method comprises adding one or more radical scavenging and/or antioxidative additive preferably selected from the group consisting of sterically hindered nitroxyls, sterically hindered hydroxylamines, sterically hindered hydroxylamine salt compounds, sterically hindered amino compounds and sterically hindered N-hydrocarbyloxyamines, benzofuranone compounds, as obligatory component(s) to the medium used during biosynthesis.

Methods in cell cultures, and related inventions, employing certain additives

The invention relates to an arrangement, comprising a solid carrier and a matrix arranged on the solid carrier, said matrix comprising at least one enzymatically convertible or modifiable molecule and comprising at least one enzyme that can be released by the conversion or modification of the molecule, said enzyme being capable of converting at least one color-changing substrate located in the matrix and/or on the solid carrier.

Test arrangement

The present invention provides the use of surface active proteins, especially class I and class II hydrophobins, in topically applied pharmaceutical formulations. The invention is particularly directed to topically applied pharmaceutical products for enhancing the penetration to achieve a transungual delivery of a prophylactically and/or therapeutically effective amount of an active ingredient (drug) to a patient (including animals and humans) into and/or through a nail, of the animal or human body, in order to treat one or more of a variety of diseases or disorders. Related embodiments of the invention are also disclosed.

Compositions, use and method for the use of surface active proteins in topical drug delivery across keratin

By treatment with hydrophobins, cellulosic materials such as paper, cardboard, cotton or, especially, wood-based materials, such as solid wood, glued wood products or particle board, can be effectively protected against absorption of and attack by water and/or moisture.

Method of treating cellulosic materials with hydrophobins

The invention relates to a use of surface active hydrophobins for applications in pharmaceutical technology, in particular as excipients for galenic use. Provided is a method for either admixture of hydrophobins to galenic compositions or for treating the surface of pharmaceutical forms with a hydrophobin-containing solution to modify the pharmaceutical properties of the galenic form. In a preferred embodiment of the invention hydrophobins are used to improve the properties of a pharmaceutical composition, e.g. to act as a surfactant or to increase resistance to disintegration of the galenic forms to achieve a retarded drug release. The galenic form to be modified by the use of surface active proteins as excipients can be capsules, tablets, pills, microparticles, vesicles, and suppositories, although further galenic forms are envisioned. The surface active proteins used for the purpose of present invention can either be isolated from their respective natural source or prepared by recombinant techniques and expression in a suitable host.
