Trichoderma Biomass as an Alternative for Removal of Congo Red and Malachite Green Industrial Dyes

Argumedo-Delira, Rosalba, Gómez-Martínez, Mario J., Uribe-Kaffure, Ramiro·2021·Applied Sciences

Abstract

The present study evaluated the removal efficiency of two dyes, Congo red (CR) and malachite green (MG), using either fresh or dry fungal biomass of two species of Trichoderma (T. virens and T. viride) and activated carbon. After 24 h, the CR removal efficiency obtained with fresh biomass was higher than that obtained with activated carbon. For the MG dye, the average removal with activated carbon (99%) was higher than those obtained with dry and fresh biomass of T. viride and T. virens. Experimental results for fresh and dry fungal biomass showed a good correlation with Langmuir isotherms. The adsorption rates of CR and MG by of T. virens and T. viride can be more appropriately described using the pseudo-second-order rate. We found an adsorption capacity of 81.82 mg g−1 for T. virens with MG dye. Results show that fresh or dry biomass of T. virens can represent a simple and cost-effective alternative for removing industrial dyes such as CR and MG.

  • Biotreatment of dye-containing wastewater effluent by fungal cells is cost-effective, easily applicable, eco-friendly, and has no nutrient needs.

    “Biotreatment of dyecontaining wastewater effluent by fungal cell was provided a cost-effective, easily applicable, eco-friendly (Salem et al., 2019;(Argumedo-Delira et al., 2021), and absence of nutrient needs (Ghany et al., 2019).”

    From Biomass-Based Adsorbents for Removal of Dyes From Wastewater: A Review (2021) · cites this paper as Argumedo-Delira et al., 2021

    The Introduction says biological dye-removal methods, including fungal treatments, are less costly than chemical methods and are eco-friendly. It does not establish that fungal-cell treatment is easily applicable. The separate claim about having no nutrient needs is attributed to Ghany et al., not to this source. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
