Background:Laccase, a multicopper oxidoreductase (EC: 1.10.3.2), is a widely used enzyme in bioremediation of textile dye effluents. Fungal Laccase is preferably used as a remediating agent in the treatment and transformation of toxic organic pollutants. In this study, crude laccase from a basidiomycetes fungus, Phanerochaete sordida, was able to decolorize azo, antroquinone and indigoid dyes. In addition, interactions between dyes and enzyme were analysed using molecular docking studies.Methods:In this work, a white rot basidiomycete’s fungus, Phanerochaete sordida, was selected from forest soil isolates of Eastern Ghats, and Tirumala and lignolytic enzymes production was assayed after 7 days of incubation. The crude enzyme was checked for decolourisation of various synthetic textile dyes (Vat Brown, Acid Blue, Indigo, Reactive Blue and Reactive Black). Molecular docking studies were done using Autodock-4.2 to understand the interactions between dyes and enzymes.Results:Highest decolourisation efficiency was achieved with the crude enzyme in case of vat brown whereas the lowest decolourisation efficiency was achieved in Reactive blue decolourisation. Similar results were observed in their binding affinity with lignin peroxidase of Phanerochaete chrysosporium through molecular docking approach.Conclusion:Thus, experimental results and subsequent in silico validation involving an advanced remediation approach would be useful to reduce time and cost in other similar experiments.

Stewart-Williams and Halsey provide an unusually broad synthesis of the enormous literature on gender gaps in hiring, letters of recommendation, mathematical and spatial abilities, email appointment-making, people vs things orientation, within-gender variability, salaries, occupational preferences, and employment discrimination. They argue that sociocultural factors, while important, cannot by themselves account for the entirety of these gaps. In addition, they argue that factors resulting from evolutionary origins, cognitive ability gaps at the extreme right tail of the distribution, and underlying gender differences in abilities, preferences, and values are needed to explain why women are less well represented in the most math-intensive fields. In our commentary, we reprise our own recent synthesis (unpublished) of gender gaps in six domains (letters of recommendation, academic hiring, salaries, teaching evaluations, journal acceptance rates, grant funding success) and put our results in the context of these authors' arguments.
