Molecular Imprinted Biomass for the Separation of Metal Ions

研究了寡孢根霉（Rhizopus oligo.）在液体培养基中对金属离子、镧烷、铜和钴的吸附性能。Rh.oligo。菌株P12对金属的吸附量最高，为3.2 mmol/g-菌丝体。种类，这是相当的功能珠在传统的废水处理。通过对Freundlich图和Scatchard图的分析，得到了Rh.oligo的几个官能团。P12与金属的吸附有关。随着金属溶液pH的增加，镧烷和钴对金属的吸附量增加。镧烷和钴的ph依赖性斜率分别为1/3和1/8，推测金属与菌丝体的相互作用不是通过离子相互作用，而是通过配位相互作用等。对金属离子的吸附位点。应该是它们的细胞壁，我们已经通过分子印迹技术对它们进行了修饰，用于更高金属吸附性的真菌。

Adsorption performance of metal ion, lanthane, copper, and cobalt, by Rhizopus oligosporus (Rh.oligo.) fermentated in liquid media were investigated. Rh.oligo. P12 demonstrated the highest metal-adsorption amount, whose amount of metal adsorbed was 3.2 mmol/g-mycelia, among the Rh.oligo. species, which was comparable to the functional beads for conventional wastewater treatments. From the analysis of Freundlich and Scatchard plots, the several functional groups of Rh.oligo. P12 were concerned with the adsorption of metal. With increasing pH in metal solution, the amount of metal adsorbed was increased for lanthane and cobalt. The pH-dependence slope of lanthane and cobalt were 1/3 and 1/8, respectively, from which the interaction between metal and mycelia was speculated to be not via ionic interaction but via coordination interaction etc. The adsorption site of metal ions by Rh.oligo. would be their cell wall, and we have been modifying them by molecular imprinting for higher metal-adsorption fungi.
