Biosensors are obtaining an increasing significance for analytical purposes as well as for on-line monitoring and control in biotechnological processes [1]. In the special field of food industry enzyme and microbial biosensors are suited. With enzyme sensors one can analyse in mostly high specific reactions many substances – microbial sensors normally are unspecific. But they have the advantage of high stability and there is no necessity of enzyme isolation and purification. On the basis of the manifold of microbial metabolic pathways one can expect a wider range of application for microbial sensors, much more as existent for enzyme sensors. This paper is dealing with a microbial aspartam sensor. 相似文献

A crayfish for cancer research Marmorkrebs (or marbled crayfish) is a triploid crayfish known since the mid‐1990s, which reproduces parthenogenetically. It originated from the North American decapod species Procambarus fallax and was distributed as a popular aquarium pet. Subsequent anthropogenic releases have resulted in the establishment of several stable populations in the wild that constitute a serious invasive threat. Interestingly, marbled crayfish use a parthenogenetic mode of reproduction that results in the generation of clones with minimal genetic variation. In addition, the animals can be easily bred and manipulated in the laboratory. These features establish marbled crayfish as a novel and innovative model organism for tumor biology, particularly for the analysis of clonal evolution and epigenetic adaptation of tumor genomes. 相似文献
