摘要： The present invention provides electrospun polymer fibers comprising bacteria-containing hydrogel particles. Bacteria-containing hydrogel particles are produced by crosslinking water-soluble polymers to form hydrogels and mixing them with a bacteria suspension. The crosslinking is suitable to be carried out either chemically before the addition of the bacteria suspension or physically before or after this addition. Subsequently, these hydrogel particles are electrospun together with an electrospinnable polymer solution to form fibers or fibre non-wovens.The bacteria which are located in these hydrogel particles or in the electrospun polymer fibers comprising these particles, respectively, are capable of surviving for a long period (several months) without the supply of water or cell-culture media and are simultaneously protected against the effect of solvents, for example alcohols, acetone, chlorinated hydrocarbons, ethers and toluene, which would otherwise kill said bacteria. The bacteria are suitable to be released again at any time through contact with water and to be replicated under normal culture conditions.The electrospun polymer fibers according to the present invention comprising bacteria-containing hydrogels are suitable for use in the dry storage of useful bacteria or for killing harmful bacteria. Textiles and membranes, for example, are suitable to be equipped with it. However, they are also suitable for applications in wastewater treatment, environmental protection (water pollution control), the agricultural and food sector, pharmacy, fermentation, and the building industry.
摘要翻译：本发明提供了包含含细菌的水凝胶颗粒的电纺聚合物纤维。通过交联水溶性聚合物以形成水凝胶并将其与细菌悬浮液混合来制备含细菌的水凝胶颗粒。交联适用于在添加细菌悬浮液之前进行化学反应，或在物理加入之前或之后进行。随后，将这些水凝胶颗粒与电纺丝聚合物溶液一起电纺丝以形成纤维或纤维无纺布。分别位于这些水凝胶颗粒或包含这些颗粒的电纺聚合物纤维中的细菌能够长时间（几个月）存活，而不需要供应水或细胞培养基，并同时被保护免受影响的溶剂，例如醇，丙酮，氯代烃，醚和甲苯，否则会杀死所述细菌。细菌可以随时通过与水接触再次释放并在正常培养条件下复制。包含含细菌水凝胶的本发明的电纺聚合物纤维适用于干燥储存有用细菌或杀死有害细菌。纺织品和膜例如适合配备它。但也适用于污水处理，环境保护（水污染防治），农副食品，制药，发酵，建筑等行业。

Subsequently, an aliphatic or aromatic sulfide is firstly added, followed by a solution of at least one organosoluble metal salt in an aprotic organic solvent and finally a homogeneous reducing agent. The metal cation is hereby reduced to the metal. Metal-containing nanoparticles are formed which are covalently bonded to the growing anionic polymerizates.The metal salts are preferably salts of silver, copper, gold, tin, lead, chrome or zinc, or mixtures thereof.

Furthermore, they are suitable for the production of inks. If the underlying metals are those metals that show plasmon resonance, the particles are suitable to also be applied in sensors which use the plasmon resonance effect.The metal-containing nanoparticles enveloped with polymers which are accessible using the method according to the present invention do not aggregate or agglomerate, and their physical and chemical properties remain unchanged over a long period of time.
