New Type Biomembrane: Transport and Biodegradation of Reactive Textile Dye

Abstract

In traditional separation processes, there are environmental risks still because of the presence of toxic agents. Thus, a novel biomembrane microreactor named eco-green biomembrane (EgBM) was developed to perform the transport, biodegradation, and cleaning of a textile dye aqueous solution (3 mg/L) from the donor (i.e., textile dye) to the acceptor (i.e., laccase enzymes) phases. In the present work, Morchella esculenta pellets were used as carriers and degraders instead of using the traditional chemical carriers. The optimized EgBM was made of cellulose triacetate (16.1%) as a base polymer, 2-nitrophenyl octyl ether (25.2%) as a plasticizer, and M. esculenta fungus pellets (58.7%) as both carriers and degraders. A decoloration percentage of 98.6% ± 0.8 in 60 h was attained, which was due to two mechanisms: biosorption (15.4% ± 0.1) on fungal mycelium and biodegradation (83.2% ± 0.6) by laccase enzymes. The EgBM was achieved not only by the transport of reactive textile dyes used in the donor phase but also by the biodegradation and biosorption of the dyes.

A review on adsorbent parameters for removal of dye products from industrial wastewater

“…Reactive dyes are soluble in water, and 5-10% of these dyes enter the dye bath and are present in the colored effluent, which creates serious problems for the environment (Hynes et al 2020). Removal of reactive dyes and their degradability in biological systems using conventional wastewater treatment techniques is low (Dayı et al 2020). For this reason, focusing on specific methods of removing dye from industrial effluents helps to select a treatment system appropriate to the type of pollution.…”

Synthesis, X-ray crystal structure, IR and Raman spectroscopic analysis, quantum chemical computational and molecular docking studies on hydrazone-pyridine compound: As an insight into the inhibitor capacity of main protease of SARS-CoV2

“…The stretching vibration of C=N groups were observed at 1030, 1239, 1589 cm −1 in FTIR and 1031, 1257, 1590 cm −1 in FTRaman and scaled calculated bands at 1045, 1216, 1264, 1319, 1437, 1504, 1554, 1601 cm −1 for CCPEHP molecule. The C-H stretching vibrations in compounds containing aromatic groups are generally in the range 3000-3100 cm −1 [ 51 , 52 ]. The absorption peaks at 3069 and 3025, 3055 cm −1 were assigned to the FTRaman and FTIR spectra.…”

Fungal assisted bio‐treatment of environmental pollutants with comprehensive emphasis on noxious heavy metals: Recent updates

“…Study on the mycoremediation of dyes is not limited to the above demonstrated works. There are a significant numbers of research works in which fungal sources have been successfully utilized in the dyes degradation, decolorization and detoxification studies (Al‐Tohamy et al, 2020; Ben et al, 2020; Bu et al, 2020; Dayı et al, 2020; Eichlerová & Baldrian, 2020; Karim et al, 2020; Purnomo & Mitha Ocdyani Mawaddah, 2020; Ramadhan et al, 2021; Sharma et al, 2017; Sowjanya et al, 2020). Table 1 shows the involvements of various fungi in the remediation of different dyes.…”
