    摘要： Mutacin are bactericidal substances of proteinaceous natures produced by Streptococcus mutans. Lantibiotics are antibacterial substances containing posttranslationnally modified amino acids such as lanthionine. The present invention teaches a simple method of purifying mutacin B-Ny266 from Streptococcus mutans strain Ny266 to homogeneity. The present invention further teaches the primary amino acid sequence of mutacin B-Ny266 as well as its proposed modified structure. Further, the present invention teaches compositions comprising mutacin B-Ny266 as well as methods for the treatment and/or prophylaxy of bacterial infections comprising an administration of a suitable dose of composition comprising mutacin B-Ny266.

    摘要： The present invention relates to a multilayer structure comprising a transparent polyamide-based layer and a layer based on a thermoplastic polyurethane (TPU). The invention also relates to a decorated article consisting of an object to which the above structure has been bonded, the polyamide layer being on the outside. According to another embodiment, the polyamide/TPU structures may be bonded to a polyurethane foam or to a polyurethane resin. It is also possible to overmould the polyurethane foam or the polyurethane resin to the polyamide/TPU structure placed in a mould, the polyamide layer being adjacent to the mould wall. The structure obtained is useful, for example for making skis or sports shoes. The invention also relates to these structures. Advantageously, the polyamide layer is semicrystalline. Advantageously, the TPU layer is transparent. Each of the layers may be formed from several layers.
