“…Interestingly, it has been reported that the optimum pH is important to get better results regarding the removal of heavy metal ions using fungal isolates [37,38]. In many cases, the optimal value of pH was 5.0, which shows a maximum removal of heavy metal ions (Pb(II), Cd(II), As(III), and Hg(II)) by fungus isolates such as Penicillium purpurogenum [37,38]. Figure 1b exhibits the incubation time effect on the Cd uptake and percentage removal from the liquid medium by T. fasciculatum and T. longibrachiatum.…”

The objective of this paper is to establish the significance of the mycoremediation of contaminants such as Cd2+ to achieve sustainable and eco-friendly remediation methods. Industries such as electroplating, paint, leather tanning, etc. release an enormous amount of Cd2+ in wastewater, which can drastically affect our flora and fauna. Herein, we report on the in vitro bioadsorption of Cd2+ ions using fungal isolates obtained from different contaminated industrial sites. The detailed studies revealed that two fungal species, i.e., Trichoderma fasciculatum and Trichoderma longibrachiatum, were found to be most effective against the removal of Cd2+ when screened for Cd2+ tolerance on potato dextrose agar (PDA) in different concentrations. Detailed adsorption studies were conducted by exploring various experimental factors such as incubation time, temperature, pH, inoculum size, and Cd2+ salt concentrations. Based on optimum experimental conditions, T. fasciculatum exhibited approximately 67.10% removal, while T. longibrachiatum shows 76.25% removal of Cd2+ ions at pH 5.0, 120 h incubation time, at 30°C. The inoculum sizes for T. fasciculatum and T. longibrachiatum were 2.5% and 2.0%, respectively. Finally, the morphological changes due to Cd2+ accumulation were examined using scanning electron microscopy (SEM). Further, Fourier transform infrared spectroscopy (FTIR) spectroscopy reveals the presence of various functional groups (-CH, –C=O, NH and –OH), which seem to be responsible for the efficient binding of Cd2+ ions over the fungal surfaces.

In order to control and remediate arsenic (As) contaminated soil, sediment or water, fungi are used to investigate their potential accumulation and volatilization of As. In this study, after cultivation for 2 days, the dry weights of mycelia for Trichoderma asperellum, Fusarium oxysporum and Penicillium janthinellum all show an increased trend when the As(V) concentration ranges from 0 -50, 0 -50, 0 -80 mg/L, respectively. When the culture system is loaded with 2500 lg As(V), which represents 50 mg/L As, and cultivated for 5 days, P. janthinellum presents the highest efficiency of 87.0 lg/g for As bioaccumulation, and the order of the efficiency for As bioaccumulation is P. janthinellum A T. asperellum A F. oxysporum. However, the order of the amount of volatilized As is F. oxysporum A P. janthinellum A T. asperellum, and the highest amount of volatilized As is observed for F. oxysporum at 181.0 lg. Thus, the ability of As bioaccumulation and biovolatilization for T. asperellum and P. janthinellum is reported for the first time in this study.

It is expected that microorganisms capable of arsenic (As) accumulation and volatilization can be used to remediate As‐contaminated environments. In this paper, the arsenite [As(III)] resistance, accumulation, and volatilization properties of Trichoderma asperellum SM‐12F1, Penicillium janthinellum SM‐12F4, and Fusarium oxysporum CZ‐8F1 were investigated. The results indicated that all three fungal strains exhibited significant As(III)‐resistance. After being exposed to 40 and 80 mg/L As(III) for five days, the dry mycelium weights of P. janthinellum SM‐12F4 and F. oxysporum CZ‐8F1 were significantly increased compared to the controls. The spiked As(III) initially inhibited and subsequently promoted fungal growth (mainly in the logarithmic growth phase). The maximal biomasses of 0.25, 0.29, and 0.29 g for T. asperellum SM‐12F1, P. janthinellum SM‐12F4, and F. oxysporum CZ‐8F1 after exposure to As(III), respectively, were all higher than their corresponding controls without As(III). When exposed to 40 mg/L As(III) for five days, the efficiencies of As(III) accumulation for T. asperellum SM‐12F1, P. janthinellum SM‐12F4, and F. oxysporum CZ‐8F1 were 53.02, 13.67, and 13.65 µg/g/day, respectively, and the efficiencies of As(III) volatilization were 51.87, 54.34, and 46.35 µg/g/day, respectively. It seems that these fungal strains can be used in the future to tackle As‐contaminated environments.
