Abstract

AIMS

The aim of this study was to investigate the biosorption of copper to the pellets of different wood-rotting fungal species.

METHODS AND RESULTS

Copper sorption was studied in both batch and column arrangements. The optimum pH for copper sorption was between 3.5 and 4. In 100 mg l(-1) Cu (II), maximum qe values were found for Oudemansiella mucida (8.77 mg g(-1) dry wt), Lepista nuda (6.29 mg g(-1)), Pycnoporus cinnabarinus (5.08 mg g(-1)) and Pleurotus ostreatus (4.77 mg g(-1)). Both biomass yield and specific sorption were influenced by the composition of the fermentation broth. The results of column experiments showed that mycelial pellets of wood-rotting fungi can be considered as promising biosorbent material.

CONCLUSIONS

Pellets of wood-rotting fungi showed the same or better copper sorption properties as those previously reported for lower fungi or filamentous bacteria, as well as good mechanical properties.

摘要

目的

本研究旨在探究不同木材腐朽真菌菌球对铜的生物吸附作用。

方法与结果

采用分批和柱式装置研究铜的吸附。铜吸附的最佳pH值在3.5至4之间。在100 mg l(-1) Cu (II) 中，黏液奥德蘑（8.77 mg g(-1) 干重）、裸口蘑（6.29 mg g(-1)）、朱红密孔菌（5.08 mg g(-1)）和平菇（4.77 mg g(-1)）的最大qe值被发现。生物量产量和比吸附都受发酵液成分影响。柱式实验结果表明，木材腐朽真菌的菌丝球可被视为有前景的生物吸附材料。
