A detergent or cleaning agent that has an antimicrobial effect and includes at least one tetracarboxylic acid or the salts thereof in combination with at least one biocidal quaternary ammonium compound.

Detergent or cleaning agent having GLDA-enhanced antimicrobial effect

The present invention relates to aqueous peptide-functionalized polyurethane dispersions that can be used as adhesives, in particular for metal surfaces, such as steel surfaces. As hybrid materials, they provide for a versatile system that can be finely tuned and combine the advantageous properties of polyurethane and peptide materials. Also encompassed are processes for their production, compositions containing them and their use as coatings and adhesives.

Aqueous peptide-functionalized polyurethane dispersions

The present invention relates to peptides, in particular dodecapeptide-containing coating agents, adhesion promoters or adhesives for oxidic surfaces, a multilayer composite or a coated substrate, containing compounds which are formed entirely or in part of dodecapeptides as adhesion promoters between at least two adjacent layers of the composite or between the coating and the substrate, and to dodecapeptides that can be used as coating agents, adhesion promoters or adhesives for oxidic surfaces.

Peptides that can be used in coating agents, adhesion promoters or adhesives for oxidic surfaces

The present invention relates to 25 hitherto undescribed genes ofand gene products derived therefrom and all sufficiently homologous nucleic acids and proteins thereof. They occur in five different metabolic pathways for the formation of odorous substances. The metabolic pathways in question are for the synthesis of: 1) isovalerian acid (as part of the catabolism of leucine), 2) 2-methylbutyric acid and/or isobutyric acid (as part of the catabolism of valine and/or isoleucine), 3) butanol and/or butyric acid (as part of the metabolism of butyric acid), 4) propyl acid (as part of the metabolism of propionate) and/or 5) cadaverine and/or putrescine (as parts of the catabolism of lysine and/or arginine). The identification of these genes allows biotechnological production methods to be developed that are improved to the extent that, to assist these nucleic acids, the formation of the odorous substances synthesized via these metabolic pathways can be reduced by deactivating the corresponding genes in the micro-organism used for the biotechnological production. In addition, these gene products are thus available for preparing reactions or for methods according to their respective biochemical properties.

The invention relates to five or four novel genes and the gene products thereof fromand sufficiently similar genes and proteins which are involved in vivo in the formation of polyamino acids. The gene in question is ywsC, ywsC', ywtA, ywtB and ywtD or proteins coded thereby. The gene ywsC, ywsC&#x2032;, ywtA and ywtB can be used to improve biotechnological production methods by microorganisms, wherein they are functionally inactivated; the gene ywtD which codes for a peptide decomposing poly-gamma glutamate can, inversely, contribute to the improvement of biotechnological production methods by increased expression. Said genes can be used positively, preferably to result in a modification or decomposition of poly-gamma glutamate.
