“…Polyurethane foam was chosen as the best matrix of support for the decolourization of methylene blue dye as supported by previous findings. A study on the utilization of bacterial cells immobilized on polyurethane foam to treat denim industry wastewater has been reported [14]. The immobilization of bacterial cells on polyurethane foam provided significantly higher operational stability and longevity of cells compared to that of free cells and bacterial cells immobilized in calcium alginate which is in line with the current study [14].…”

Methylene blue is widely utilized as biological stains, in printing and as commercial textile dye. The increasing presence of textile dye in wastewater for instance represents environmental hazards. Therefore, there is a significant interest in developing cost effective and environmentally friendly methods for methylene blue removal from industrial wastewater. Taking this into consideration, in the present study, twenty three locally isolated Rhodococcus strains were examined as biological tools for decolourization of methylene blue. Among the tested microorganisms, five locally isolated Rhodococcus strains demonstrated promising ability to decolourize methylene blue as evidenced by the change in the colour of the dye from dark blue to pale blue on nutrient agar plates. One particular strain namely Rhodococcus strain UCC 0003 formed clear zone around the colonies of the bacteria with the biggest diameter of 2.0 ± 0.1 cm after 2 days of cultivation time. This strain demonstrated good growth and completely decolourized 0.1 g/L methylene blue after 5 days of incubation period. Secondary characterization was carried out by comparing the ability of resting cells and immobilized cells of Rhodococcus strain UCC 0003 for efficient methylene blue removal. The results showed that the highest percentage of methylene blue decolourization was achieved by using polyurethane foam cubes as the immobilization matrix resulting in 83 a ± 1 % compared to that of 63 b ± 3 % when resting cells was employed as the biocatalyst. These findings clearly indicated that the immobilized cells of Rhodococcus strain UCC 0003 has a huge potential as biological tool to remediate actual wastewater containing methylene blue.

“…Membrane bioreactors are among the most common methods for bioremediation of impurities in the environment, including textile dyes (Spagni et al, 2012;Prabha et al, 2017;Al-Rashed & Lakhouit, 2022). Moreover, the literature has shown numerous studies that have proven the efficient use of individual and microbial consortiums with dye concentrations of up to 1000 mg/L (Kurade et al, 2017;Lade et al, 2015;Rajendran et al, 2015). Table 3 presents more details on biological treatment methods.…”

To reduce the impact of the novel SARS-CoV-2 virus, popularly known as the Coronavirus, many public health-related rules have been established around the world. Along with social distancing and lockdowns, most countries have mandatory wearing of face masks in public areas to limit the spread of the virus during the COVID-19 pandemic. However, because people are free to choose any method to make their masks, some are being fabricated from materials that can be toxic to the environment and human health. This paper discusses how inks and dyes used in face masks are causing major environmental degradation and health issues in industry workers and the general mask-wearing public. The goal fixed for the present study is to raise the alarm with authorities and decision-makers regarding the toxic nature of some colors (dyes and inks) and fabrics in the masks being worn every day.

“…In the previous investigation (Belouhova et al, 2014), the bacteria from genus Pseudomonas played an important role in the adaptation of biofilms for the biodegradation of azo dyes. This study focused on increasing the potential of tested isolates to generate stable bonding with the abiotic surface in the form of a biofilm (Rajendran et al, 2015). A bacterial adherence study on the abiotic surface was investigated using 96-well microtitre polystyrene plates, as reported by Chaieb et al (2016).…”

Azo dyes, which are highly toxic, carcinogenic, and mutagenic for living organisms, are used as coloring chemicals in textile industries. Physicochemical methods used for removing azo dyes are expensive, can generate secondary waste, and are not very efficient. In this study, we used a biological approach to reduce the toxicity of three azo dyes, i.e., congo red, methyl orange, and reactive red 198, from textile effluents. Six dye-decolorizing bacteria were screened from waste water obtained from the textile industry (in the dyeing process) at a concentration 100 mg/l for each azo dye. Using a 16S rRNA approach, the bacteria were identified and assigned as Enterococcus faecalis VTK04, Staphylococcus aureus VTK013, Pseudomonas aeruginosa VTK018, Proteus mirabilis VTK024, Bacillus cereus VTK035, and Enterococcus faecium VTK054. These bacteria were tested for their ability to produce biofilms on the abiotic surface. The adherence assay showed that VTK013, VTK054, and VTK024 had a potential to form stable biofilms on abiotic surfaces (OD570 = 1.37). Moreover, the dye decolorization potential was spectrophotometrically measured after seven days with and without a carbon substrate. The results demonstrated that the absence of the carbon source had a negative impact on decolorization, whereas a carbon-supplemented medium showed a considerable increase in the decolorization of congo red (80% and 96% by VTK013 and VTK018, respectively), methyl orange (100% and 75% by VTK054 and VTK035, respectively), and reactive red 198 (90% and 86% by VTK04 and VTK024, respectively). The phytotoxicity study of the treated dye solutions showed lesser toxicity compared to the untreated dye solution. These results support the possibility of using bacterial isolates for the biodegradation of azo dye effluents.
