Isolation of glucosinolate degrading microorganisms and their potential for reducing the glucosinolate content of rapemeal

Abstract K88ab fimbriae are filamentous protein structures at the surface of certain enterotoxigenic Escherichia coli strains. Electron microscopy analysis of K88ab fimbriae showed that these structures have different morphological appearances dependent on the medium in which cells expressing these fimbriae or in which purified fimbriae were suspended. Thin and curled structures, thin and flexible fimbriae, a wider and rigid form of the fimbriae, and, in addition, paracrystalline structures were detected. Optical diffraction analysis of the paracrystalline structures indicated a helical conformation of K88ab fimbriae.
