A protein from Pleurotus eryngii var. tuoliensis C.J. Mou with strong removal activity against the natural steroid hormone, estriol: Purification, characterization, and identification as a laccase

Fungal laccase discovered but yet undiscovered

“…Other clinically generated pollutant include estrogen's whose main component estriol produced in urine, placenta during pregnancy, and primary estrogens are produced by adipose tissues of males and post-meno-pausal women which causes pollution of aquatic body. Laccase can be used for the treatment of the water body polluted with estrogens or its components (Ueda et al 2012). As the removal cost at the water treatment plant is high and requires high energy, laccase can provide cheap treatment and operational activity at room temperature.…”

Physiological Characterization of Fungal Inoculum for Biotechnological Remediation of Soils

“…RBBR de-coloration's kinetics employed to identify the ligninolytic system's total action in the de-coloration of the anthrachinonic colorant showed positive results. The similarity of laccase and RBBR de-coloration enzymatic profile proved the hypothesis that laccase was the main oxidase involved in pentachlorophenol degradation, rendering it an important biotechnological tool, which was also observed by other authors, including in degradation studies (Jeon et al 2008;Moreira Neto et al 2009;Cañas e Camarero 2010;Majeau et al 2010;Niebisch et al 2010;Gaitan et al 2011;Ding et al 2012;Eichlerová et al 2012;Moldes et al 2012;Pardo et al 2012;Ueda et al 2012;Janusz et al 2013;Manavalan et al 2013). Laccase production, with concomitant Mndependent peroxidase production showed that such enzymatic activities might be involved in the in vivo pentachlorophenol degradation under the assessed conditions, since the highest enzymatic activities in the PCP-soil were observed in the treatments with the highest degradation rates.…”

A novel laccase with inhibitory activity towards HIV‐I reverse transcriptase and antiproliferative effects on tumor cells from the fermentation broth of mushroom Pleurotus cornucopiae

“…Most of mushroom laccases exhibit their highest activities at 40–60°C, but some laccases such as P . eryngii (Ueda et al ., ) and Tricholoma giganteum (Wang and Ng, ,) laccases with the optimum reaction temperature of 70°C are exceptional.…”

“…The optimum temperature resembles A. placomyces laccase (Sun et al, 2012) and T. mongolicum laccase (Li et al, 2010). Most of mushroom laccases exhibit their highest activities at 40-60°C, but some laccases such as P. eryngii (Ueda et al, 2012) and Tricholoma giganteum (Wang and Ng, 2004b,) laccases with the optimum reaction temperature of 70°C are exceptional. The optimum pH was 4.2, which falls within the range (pH 3.0-5.0) of most previously reported laccases (Baldrian, 2006).…”
