Abstract Nowadays, trace metal contamination of soils is a worldwide concern. In the soil, the trace metals are distributed within different mineralogical fractions, which influence the transfers and the bioavailability, then the associated toxic risk. This study aims to investigate how the development of selected fungal mycelium influences the mineralogical speciation of cadmium. In a microcosm experiment with an industrial soil contaminated by various metal, including Cd, bioaugmentation experiments with the fungus Abisdia cylindrospora were conducted. A. cylindrospora showed a good development in the microcosm. Sequential extraction procedure highlighted the decrease of the potentially available fraction (5%) after 20 days of incubation. Most of the variations occur in the reducible and the oxidable fractions.

工业镉污染土壤用柱孢球孢菌进行生物强化：对镉矿物形态的影响

摘要 目前，土壤中的微量金属污染已成为全球关注的问题。在土壤中，微量金属分布在不同的矿物成分中，这会影响转移和生物利用度，进而影响相关的毒性风险。本研究旨在调查选定真菌菌丝体的发育如何影响镉的矿物形态。在对被包括 Cd 在内的各种金属污染的工业土壤进行的微观实验中，对真菌 Abisdia cylindrospora 进行了生物强化实验。A. cylindrospora 在微观世界中表现出良好的发育。连续提取程序突出了孵育 20 天后潜在可用分数 (5%) 的减少。大多数变化发生在可还原和可氧化部分。
