    • This invention discloses novel bacterial spore systems. It has now been found surprisingly that under certain conditions bacterial spore systems can be used in the food and feed industry, preferably in animal feeding and as biohybrid material. More precisely applicant has found the following: Genetically modified or genetically engineered viable spore systems expressing bioactive polypeptides, for example bacteriocins and/or enzymatically active feed enzymes, at the spore surface, have a great potential use in animal feeding. Further, it has been found that genetically modified or “genetically engineered inert spore systems expressing affinity ligands or immobilized enzymes at the surface have a great potential use in biocatalysis and in the construction of biocatalytic films. Especially the resistance to harsh chemicals, desiccation, strong pressure, or high temperatures allows the spores to be a potentially valuable tool for the display of bioactive molecules, like biocatalytic enzymes or bioactive feed enzymes that must survive harsh conditions to deliver their full potential. Finally, applicant has found that instead of translational fusions to spore structural genes as it is known from the prior art described above, passenger bioactive polypeptides, as for example enzymes, bacteriocins, affinity ligands, can also be fused to spore-specific surface enzymes, for example to spore specific enzymes as mentioned herein above.
    • 本发明公开了新颖的细菌孢子体系。 现在已经令人惊奇地发现,在某些条件下,细菌孢子体系可以用于食品和饲料工业,优选用于动物饲养和作为生物混合材料。 更准确地说,申请人已经发现以下:在孢子表面上表达生物活性多肽(例如细菌素和/或酶促活性进料酶)的基因改造或遗传工程可行的孢子体系在动物饲养中具有巨大的潜在用途。 此外,已经发现在表面上表达亲和配体或固定化酶的遗传修饰或“遗传工程惰性孢子体系在生物催化和生物催化膜的构建中具有很大的潜在用途。 特别是对苛刻化学品,干燥,强压或高温的抵抗能使孢子成为显示生物活性分子(如生物催化酶或生物活性饲料酶)的潜在有价值的工具,生物活性分子必须经受恶劣条件才能发挥其潜力。 最后,申请人已经发现,如从上述现有技术已知的那样,代替融合孢子结构基因的翻译融合,也可以将游离生物活性多肽(例如酶,细菌素,亲和配体)与孢子特异性表面酶融合, 例如如上所述孢子特异性酶。
