“…Previous studies not only showed that white-rot fungi (WRF) have the capability to degrade PCBs in liquid, soil and sediments but also demonstrated their adaptive ability to grow under critical environmental conditions (Stella et al 2017). WRF such as Phanerochaete chrysosporium (Kamei et al 2006a; Čvančarová et al 2012), Phlebia brevispora (Kamei et al 2006b), Coriolus versicolor (Cloete and Celliers 1999; Čvančarová et al 2012), Irpex lacteus, Bjerkandera adusta, Pycnoporus cinnabarinus, Phanerochaete magnolia, Pleurotus ostreatus (Stella et al 2017) and Dichomitus squalen s (Čvančarová et al 2012) have already proved their potential for removal of PCBs. WRF possess a ligninolytic enzyme complex comprising, among other enzymes, lignin peroxidase (LiP, EC 1.11.1.14), manganese peroxidase (MnP, EC 1.11.1.13) and laccase (Lac, EC 1.10.3.2), involving as well in the oxidation of a wide range of organopollutants.…”

The aim of the present study was to assess the ability of different white-rot fungi to tolerate polychlorinated biphenyls (PCBs) using predictive mycology, by relating fungal growth inhibition to ligninolityc enzyme secretion. Fungal strains were grown in the presence of PCBs in solid media and their radial growth values were modelled through the Dantigny-logistic like function in order to estimate the time required by the fungal colonies to attain half their maximum diameter. The principal component analysis (PCA) revealed an inverse correlation between strain tolerance to PCBs and the laccase secretion over time, being laccase production closely associated with fungal growth capacity. Finally, a PCA was run to regroup and split between resistant and sensitive fungi. Simultaneously, a function associated with a model predicting the tolerance to PCBs was developed. Some of the assayed isolates showed a promising capacity to be applied in PCB bioremediation.Abbreviations: Polychlorinated biphenyls (PCBs), white-rot fungi (WRF)

“…Therefore, bio-remediation is an efficient and inexpensive technique used to detoxify or remove Ni contamination from the soil and to provide land that is free from Ni toxicity for crop cultivation. This represents an alternative way of providing safe food for humans, thus preventing the development of lethal disorders induced by Ni toxicity (Kamran et al, 2015; Stella et al, 2017). Hence, the development of economical and reliable strategies is required for the removal or detoxification of heavy metals in order to avoid metal pollution of the environment and to provide safe food for human consumption.…”

Endophytic Paecilomyces formosus LHL10 Augments Glycine max L. Adaptation to Ni-Contamination through Affecting Endogenous Phytohormones and Oxidative Stress

This study investigated the Ni-removal efficiency of phytohormone-producing endophytic fungi Penicillium janthinellum, Paecilomyces formosus, Exophiala sp., and Preussia sp. Among four different endophytes, P. formosus LHL10 was able to tolerate up to 1 mM Ni in contaminated media as compared to copper and cadmium. P. formosus LHL10 was further assessed for its potential to enhance the phytoremediation of Glycine max (soybean) in response to dose-dependent increases in soil Ni (0.5, 1.0, and 5.0 mM). Inoculation with P. formosus LHL10 significantly increased plant biomass and growth attributes as compared to non-inoculated control plants with or without Ni contamination. LHL10 enhanced the translocation of Ni from the root to the shoot as compared to the control. In addition, P. formosus LHL10 modulated the physio-chemical apparatus of soybean plants during Ni-contamination by reducing lipid peroxidation and the accumulation of linolenic acid, glutathione, peroxidase, polyphenol oxidase, catalase, and superoxide dismutase. Stress-responsive phytohormones such as abscisic acid and jasmonic acid were significantly down-regulated in fungal-inoculated soybean plants under Ni stress. LHL10 Ni-remediation potential can be attributed to its phytohormonal synthesis related genetic makeup. RT-PCR analysis showed the expression of indole-3-acetamide hydrolase, aldehyde dehydrogenase for indole-acetic acid and geranylgeranyl-diphosphate synthase, ent-kaurene oxidase (P450-4), C13-oxidase (P450-3) for gibberellins synthesis. In conclusion, the inoculation of P. formosus can significantly improve plant growth in Ni-polluted soils, and assist in improving the phytoremediation abilities of economically important crops.

“…Furthermore, white-rot fungi were also found to degrade a large number of single or mixed matrix contaminants (Pointing et al, 2001). The ability of degradation of multiple single substrate pollutants by white-rot fungi had also been demonstrated in some recently conducted studies (Ren et al, 2012;Stella et al, 2016). On the basis of these revelations, the degradation behavior and kinetic characteristics of four co-substrate systems in simulated coking wastewater were studied in this paper.…”
