The sorption capacity of the cultures Trichosporon capitatum and Aspergillus niger towards zinc dissolved in the culture liquid was studied by radio active labelling. The curves of sorption kinetics and the so-called sorption quasi-isotherms showing the dependence of zinc sorption by the microbial biomass upon zinc concentration in the liquid medium were derived. For the Aspergillus niger culture at zinc concentrations of 0.5 to 52 mug/ml the sorption quasi-isotherm was linear. The zinc extraction by microorganisms was related not only to the physico-chemical sorption but also to the zinc accumulation in the cell biopolymers. The paper presents calculations of the microbiological purification of sewage waters from zinc by means of the Aspergillus niger culture.
通过放射性标记研究了头状丝孢酵母和黑曲霉培养物对溶解在培养液中的锌的吸附能力。得出了吸附动力学曲线以及所谓的吸附准等温线，该曲线显示了微生物生物量对锌的吸附取决于液体培养基中锌的浓度。对于锌浓度为0.5至52微克/毫升的黑曲霉培养物，吸附准等温线是线性的。微生物对锌的提取不仅与物理化学吸附有关，还与细胞生物聚合物中锌的积累有关。本文介绍了利用黑曲霉培养物对污水中锌进行微生物净化的计算。
