AB  - Some fungi are able to control and remediate arsenic (As)-contaminated soil, 
      sediment, or water. Here, we investigate potential accumulation and 
      volatilisation of As by three fungi strains. Results indicated that the highest 
      level of As was accumulated by Penicillin janthinellum with 39.54 mug after 
      10 days in the culture system amended with 2,500 mug As(V), which represents 
      50 mg/l As. Fusarium oxysporum showed the highest amount of volatilised As with 
      304.06 mug after 15 days. The As content in the treated system (filter 
      paper + As + fungi) was significantly higher than that in the control (filter 
      paper + As; filter paper + fungi; filter paper). Trichoderma asperellum and F. 
      oxysporum showed superior abilities for the absorption of extracellular As and 
      accumulation of intracellular As, which accounted for 82.2 and 63.4% of the total 
      accumulated As, respectively. However, P. janthinellum presented an equal 
      distribution of intracellular and extracellular As. Scanning electron microscope 
      (SEM) analysis suggested that little impact on mycelium growth of the three 
      fungal strains was seen after exposure to 50 mg/l As(V) for 5 days, while the 
      growth of fungi in the control was inhibited. The present results demonstrate 
      that P. janthinellum, F. oxysporum, and T. asperellum would be expected to tackle 
      As-contaminated environments.
