| 描述 | NSC 8751 (Synonyms: (E)-2-Butenoic acid; (E)-Crotonic acid; trans-2-Butenoic acid; trans-Crotonic acid) is an endogenous metabolite. Strong herbicidal properties of crotonic acid and its availability after release to soil combined with its high level in seeds suggest that it might be considered as an allelopathic and autotoxic factor in the seeds[1]. Hydrophilic polymers are obtained via graft copolymerization of PU with acrylic acid (AA) and crotonic acid (CA). The membranes are prepared by solvent-casting method and characterized by FTIR spectra and SEM analysis. The diffusion measurements are performed using a diffusion cell during 10 h at 37 degrees C. Permeability coefficients calculated from diffusion experiments are found to be approximately three times higher in hydrophilic membrane than hydrophobic PU membrane. The adherence of Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) onto the membranes at 37 degrees C, the microorganisms didn't adhere onto the membranes compared by control suspension[2]. A Gram-positive spore former (Bacillus megaterium) was distinguished by an abundant peak for crotonic acid evident in positive and negative ions and not observed with M. luteus[3]. | ||
