With the rapid development of the textile and printing industries, dye pollution has emerged as an increasingly pressing concern. This study found that Stropharia rugosoannulata exhibits superior decolorization efficiency for various synthetic dyes, including azo dyes, anthraquinone dyes, and triphenylmethane dyes, compared to Pleurotus ostreatus, Lentinula edodes, and Hypsizygus marmoreus. S. rugosoannulata effectively decolorizes dyes in artificial textile effluents, with further enhancement observed upon the addition of metal ions (e.g., Mn²⁺, Cu²⁺, Fe²⁺) to the growth medium. Notably, S. rugosoannulata can degrade specific fabric dyes, such as remazol brilliant blue R (RBBR), acid red 73 (AR73), and a mixture of six dyes at 400 mg/L, achieving substantial degradation within 15 h. Mass spectrometry analysis revealed that two laccases, SrLAC1 (MDBSrug1_00049) and SrLAC9 (MDBSrug1_07931), are associated with dye degradation. These laccases were heterologously expressed in Pichia pastoris and purified. In vitro experiments demonstrated that the purified laccases efficiently degrade dyes (e.g., RBBR, methyl orange (MO), bromophenol blue (BPB)) in the presence of mediators. When immobilized using copper sulfate (CuSO₄) as the carrier, the laccases retained over 60 % degradation efficiency toward RBBR, MO, and BPB. Gas chromatography-mass spectrometry (GC-MS) analysis of the degradation intermediates of RBBR, MO, and BPB elucidated the potential laccase-mediated dye degradation pathways and products, offering novel insights into the remediation of dye-contaminated environments. This study demonstrates that S. rugosoannulata and its laccases (SrLAC1 and SrLAC9) possess significant potential as effective bioremediation agents for eliminating synthetic dyes from contaminated environments.

Hydrogels are cross-linked polymeric networks with wide applications in drug delivery, tissue engineering, biosensing, and environmental remediation. These hydrogels additionally host living cells, small molecules, and biological propagules, which further expand the applications of these materials. However, most, if not all, fabrication methods require covalent modifications. In this work, by deliberately selecting polymers with a known propensity to phase separate and formulating compositions far from the binodal boundary, we demonstrate the propensity of the system to transition directly into viscoelastic liquids or gels. This behavior is demonstrated using a model system of poly(ethylene glycol) (PEG) and dextran (DEX). We carried out rheological studies to provide insights into the viscoelastic behavior of these gels. We systematically characterized the gels through colorimetric assays, FTIR, MALDI-TOF, and thermogravimetric analysis (TGA) to discern the molecular compositions and solvent content of the gels. These experimental findings are supplemented with coarse-grained (CG) simulation insights to investigate the mechanistic origins of phase separation propensity with varying molecular weights of DEX. We utilized coexisting densities in the two phases using CG simulations to predict the role of DEX molecular weight in the partitioning of PEG and DEX in the two phases. Finally, we exploit the fabricated gel's ability to encapsulate live cells, antibiotics, and plant seeds. We anticipate that this ATPS-based fabrication technique will provide a scalable, cross-linker-free route to multifunctional gels, enabling advanced applications in drug delivery and responsive materials.
