“…More recently, Fernandes et al ( 2021 ) reviewed the fate and bioremediation of pharmaceuticals by aquatic environments. Other similar studies have indicated the involvement of the isolated strains in biodegradation of diverse types of compounds, such as polycyclic aromatic hydrocarbons (PAHs), phenanthrene by Comamonas testosteroni strain-T (Olukanni et al 2022 ), and also PAH by fungus Podoscypha elegans Strain FTG4 (Agrawal et al 2021 ), pharmaceutical wastes in treated sewage effluents by Bacillus subtilis 1556WTNC (Al-Gheethi and Ismail 2014 ), methylene blue by textile effluent biotreatment by Acinetobacter pitti ( Ogunlaja et al 2020 ) etc.…”

Industrialization leads to the entry of diverse xenobiotic compounds into the environment. One such compound is paracetamol (APAP), which is emerging as a pharmaceutical and personal care pollutant (PPCP). In this study, the APAP degrading bacterium was isolated by enrichment culture method from the sewage sample. The microscopy, biochemical, and 16S rRNA gene sequence analyzed the isolate PPY-2, which belongs to Bacillus licheniformis , and GenBank assigned accession number MN744328. Physiological and batch culture degradation studies have indicated that the strain involved in the degradation of APAP. The optimum pH for degradation of the PPY-2 was 7.7, whereas the temperature was 25 °C, agitation speed was 142 rpm, and concentration of APAP was 621 mg/L reported, and the optimum temperatures were 42 °C and 32 °C, respectively. Biomass kinetic was studied at optimal physical conditions, which suggested that the specific growth rate ( μ ) was 721 mg/L. The GC–MS chromatogram peaks have detected metabolites, viz., oxalic acid, 2-isopropyl-5-methyl cyclohexanone, and phenothiazine. The study confirmed that Bacillus licheniformis strain PPY-2 exhibits metabolic potential to biodegradation APAP and can be further deployed in bioremediation.

“…Several approaches have been used to remove methylene blue and other types of dyes from wastewater, including coagulation/flocculation [11], adsorption [5,[12][13][14][15], filtration [16,17], electrochemical oxidation [18], photocatalytic degradation [19], and biodegradation [20,21]. Adsorption is favorable owing to its low cost, abundant availability of adsorbent materials, high efficiency, and ease of operation [22][23][24].…”

Graphite is often converted to expanded graphite or graphene for water remediation. However, these processes require extra chemicals and energy. This study tested loose and encased pristine graphite powders for dye removal. The loose graphite exhibited good methylene blue removal (>97 % across pH levels), indicating that π‐π interaction is the governing factor besides electrostatic attraction. Notably, 5 g of loose graphite led to 100 % removal. Langmuir isotherm fitting disclosed a maximum adsorption capacity of 4.7059 mg g−1. Principal component analysis showed that dye concentration and adsorbent dosage had a greater impact than pH and contact time. However, encasing graphite in a tea bag inhibits adsorption; future studies could explore options facilitating adsorbate penetration into tea bags.

“…Different microbial biomasses (live or dead) under various conditions (aeration, temperature, pH, salinity, and pressure) illustrate an important contribution in this regard [14]. Such microbial groups show the ability to degrade MB and belong to several genera, including Bacillus, Pseudomonas, Staphylococcus, Acinetobacter, Galactomyces, Raoultella, and Aspergillus [3,[15][16][17][18][19]. Most studies have focused on the bacterial degradation of strains that grow fast, are widespread, and are highly tolerant.…”

“…Kishor et al [3] investigated an effective degrader to remove MB, Bacillus albus, isolated from textile sludge [3]. In another study, Acinetobacter pittii exhibited the ability to remove 73% of MB within five days [18]. Strain Pseudomonas aeruginosa demonstrated the degradation of MB from 82.25% to 97.82% with an increase in initial MB concentration from 50 to 200 mg/L over 24 h [17].…”

Biodegradation of Methylene Blue Using a Novel Lignin Peroxidase Enzyme Producing Bacteria, Named Bacillus sp. React3, as a Promising Candidate for Dye-Contaminated Wastewater Treatment

The emission of methylene blue (MB) from common industries causes risks to human health by making clean drinking water unavailable and hampering environmental safety. A biological approach offering a more cost-efficient and sustainable alternative solution has been studied and demonstrated to be significantly effective for the removal of MB using promising microbial isolates. Therefore, this study targeted bacterial candidates, namely Bacillus sp. React3, isolated from soil with the potential to decolorize MB. The phenogenic identification of strain React3 was performed by 16S rRNA sequencing, showing a similarity of 98.86% to Bacillus velezensis CR-502T. The ability of this bacterial strain to decolorize MB was proven through both the lignin peroxidase efficiency and accumulation in the biomass of the living cells. MB removal was determined by the reduction in the maximum absorption at a wavelength of 665 nm, which was observed to be up to 99.5% after 48 h of incubation. The optimal conditions for the MB degradation of strain React3 were pH 7, 35 °C, static, 4% inoculum, and 1000 mg/L of MB, with tryptone as a carbon source and yeast extract as a nitrogen source.
