“…Recently, reports have accumulated on the ability of various microorganisms to decolourise CR. Some examples include the ability of Colletotrichum gloeosporioides, Penicillium oxalicum, Aspergillus tubingensis, Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger and Aspergillus terreus to optimally decolourise CR at 100 ppm [13,14,15], Streptomyces sviceus and septate endophyte at 50 ppm [16,17]. This study demonstrated that the isolates SSCR1 and SSCR2 were capable of decolourising high concentrations of CR, which is comparable to recent findings.…”

The textile industry is one of the largest industries in the world and contributes positively to the economic growth of a country. However, the improper disposal of textile dye effluents results in discharging of high concentrations of textile dyes into the environment. Moreover, the inherent stability of textile dyes makes them hard to remove from the environment, which can harm organisms in polluted areas. Biological decolourisation was considered as a strategy to remediate textile dyes. Microbial decolourisation of textile dyes involves using various species of bacteria and fungi from different sources that can degrade or accumulate dye molecules. Although Indonesia is a well–known country with rich biodiversity, research on microbial decolourisation is still limited. Therefore, this study explored the decolourisation potential of microbes from the starter culture of Tuak, a traditional Indonesian alcoholic beverage made from fermented sugar palm or rice. Potential microbes were screened on yeast peptone dextrose solid agar (YPD) supplemented with various textile dyes. Isolates that formed a clear zone around the colony were further examined for decolourisation activity in broth culture media, and the decrease in dye concentration was measured spectrophotometrically. The results showed that two potential yeast isolates could decolourise Congo red and malachite green. Identification of the isolates by observation of colony and cell morphology and biochemical characteristics indicated that the two isolated yeasts belonged to the genera Saccharomyces and(or) Candida.

“…They may be monoazo, diazo, triazo, and polyazo dyes depending on their azo bond numbers. Laccase enzymes can catalyze the asymmetric cleavage of these azo bonds followed by oxidative cleavage, desulfonation, deamination, and dehydroxylation 48,49 . Although the laccase enzyme is widely used in many applications, its use in free form has disadvantages such as high cost, low stability and non‐reusability.…”

The present study aimed to immobilize laccase on dry bacterial cellulose (BC) produced by Komagataeibacter xylinus B759 in mulberry pomace waste extract as a low‐cost and natural waste by‐product and to determine the effectiveness of the obtained laccase immobilized BC (Lac/BC) for textile dye decolorization. The highest BC yield obtained after optimization studies was as 1.70 g/L in pH 8.0 medium at 32°C after 15 days. BC and Lac/BC structures were characterized by different instrumental techniques. A transition to more amorphous character was observed with the binding of the enzyme structure. The morphological properties and fiber structure of the BC and enzyme‐linked cellulose structures were examined by SEM and AFM analyses. Obtained Lac/BC pieces were used for the decolorization of Reactive Blue 171 (RB 171) and Reactive Blue 198 (RB 198) diazo dyes during the repeated‐batch process. As a result of using 12 pieces of Lac/BC, 93% and 98% decolorization values were obtained for the RB 171 and RB 198 dyes in the first use, while the color removal was still 83% and 51% at the 8th use, respectively. The results showed that BC produced in a mulberry pomace waste extract can be used for laccase immobilization and Lac/BC is an effective and promising system for textile dye decolorization.

“…Congo Red (CR) dye is used in paints, pigments, textiles, staining tissues, and the pharmaceutical industry [44]. CR dye affects different living beings in different ways, for instance, it may be carcinogenic, mutagenic, allergy causing, or organ damaging for humans, may cause infertility and toxicity in certain aquatic organisms, and may increase COD levels in water bodies, which is an indicative parameter of chemical pollution in water systems [45,46].…”

Metal nanoparticle fabrication through plant-based green methods is considered the gold standard among the various synthesis techniques owing to its simplicity, eco-friendliness, ease of use, and the huge diversity of plant species. Copper nanoparticles (CuONPs) have proven their potential in the fields of medicine, agriculture, pharmaceutics, and catalysis, and are being synthesized using various physicochemical and biological methods. Here, the authors have reported on the first-ever use of Albizia saman leaf extract for the development of CuONPs. Phytochemical analysis of the methanolic extracts of the plant exhibited the presence of phenols (32.31%), tannins (12.27%), and flavonoids (16.72%). The phytonutrients existing in leaf extract successfully reduced the copper salt in the CuONPs. A detailed investigation of the synthesized CuONPs was performed using advanced instruments. The UV-Vis spectra exhibited an absorbance peak at 290 nm, while the X-ray diffraction pattern (XRD) revealed that the average crystallite size was about 29.86 nm. Dynamic light scattering (DLS) revealed that the average hydrodynamic size of the CuONPs was 72.3 nm in diameter, while its zeta potential was −0.49, with a negative polarity. Fourier transform infrared spectroscopy showed the major bands in the region of 400 to 1000 cm−1, suggesting the formation of CuONPs, while the band in the region of 1100 to 2600 cm−1 shows the association of plant molecules with the phytonanofabricated CuO particles. Transmission and scanning electron microscopy showed the spherical shape of the CuONPs, whose size was about 20–50 nm. The phytonanofabricated CuO exhibited antibacterial activity by forming a zone of inhibition (ZOI) against Escherichia coli, Staphylococcus aureus, and Candida albicans. The removal efficiency of the CuONPs was 33.33% for Congo Red dye. The removal efficiency of the phytonanofabricated CuO for CR dye was reduced to 16% after the 4th cycle.
