“…Based on Figure 8, the adsorption of methylene blue onto banana stem is fit best to second-order pseudokinetic model. This result suggests that the methylene blue adsorption process using banana stem is chemisorption involving ion exchange between the adsorbent and methylene blue [47]. The same finding has also been reported by Zein et al [15].…”

Textile industries discharge various waste including dye waste to the environment. Dye waste such as methylene blue taints both aquatic and land ecosystem. Thus, the recent study employs banana stem (Musa balbisiana Colla), as an economical and environmentally friendly biosorbent for methylene blue removal. The chemically activated banana stem indicates the significant methylene blue uptake at pH 5, initial concentration of 800 mg L-1, contact time of 60 min, temperature at 25 °C with adsorption capacity of 71.5470 mg g-1. The adsorption process follows the Langmuir isotherm model (R2 = 0.9965) and pseudo order model which involve monolayer and chemical adsorption. The thermodynamic evaluation shows that the adsorption process occurs spontaneously and exothermic. The regeneration process indicates that the banana stem can remove methylene blue up to 90% after five times adsorption-desorption cycles.

“…B. subtilis is already described in the literature as a bacterium capable of removing dyes used in the textile industry, as shown in the work by Upendar et al (2016), who used B. subtilis immobilized in a calcium alginate matrix to remove methylene blue organic dye and reached a removal rate of 90%. Furthermore, Sarim et al, (2019) studied the ability of B. subtilis to remove the Congo red dye; at the end of the experiment they obtained a removal of 92.8% at a temperature of 35°C and pH 7.0 and the mechanism of action associated with the adsorption process.…”

The screening of organisms capable of decoloring a textile effluent was performed using 4 fungi (F24= Aspergillus spp.., F48= Aspergillus spp.., F98= Aspergillus fumigatus, FTL01=Trametes lactinea) and 2 bacteria (T9 = Bacillus subtilis, T19 = Alcaligenes faecalis). These organisms were submitted to effluent decoloration assays in which the T. lactinea fungus demonstrated the greatest decoloration capacity (51.35%); thus, it was selected as a model organism for this study. The effect of pH, temperature and carbon sources on the effluent decoloration rate by T. lactinea was studied. The effluent decoloration by T. lactinea reached levels higher than 89.77%. Finally, acute toxicity assays on Artemia salina revealed that T. lactinea treatment reduced the toxicity of raw effluent. Keywords: biodegradation, textile dyes, water treatment.

“…To date, several investigators have applied these bacterially synthesized TiO 2 NPs for antibacterial activity and for the photocatalytic degradation of various cationic and anionic dyes ( Fouda et al, 2021 ; 2022 ). Moreover, it has also been used as an antimicrobial agent under visible light ( Abd_Allah et al, 2018 ; Sarim et al, 2019 ; Nguyen et al, 2020 ). From, all the previously reported work, it is concluded that only two attempts were made for the photocatalytic degradation of various dyes from wastewater by bacteria-mediated synthesized TiO 2 NPs ( Priyaragini et al, 2014 ; Khan and Fulekar, 2016 ).…”

Over the last decade there has been a huge increase in the green synthesis of nanoparticles. Moreover, there is a continuous increase in harnessing the potential of microorganisms for the development of efficient and biocompatible nanoparticles around the globe. In the present research work, investigators have synthesized TiO2 NPs by harnessing the potential of Bacillus subtilis MTCC 8322 (Gram-positive) bacteria. The formation and confirmation of the TiO2 NPs synthesized by bacteria were carried out by using UV-Vis spectroscopy, Fourier transforms infrared (FT-IR), X-ray diffraction (XRD), scanning electron microscope (SEM), and energy dispersive X-ray spectroscopy (EDX/EDS). The size of the synthesized TiO2 NPs was 80–120 nm which was spherical to irregular in shape as revealed by SEM. FTIR showed the characteristic bands of Ti-O in the range of 400–550 cm−1 and 924 cm−1 while the band at 2930 cm−1 confirmed the association of bacterial biomolecules with the synthesized TiO2 NPs. XRD showed two major peaks; 27.5° (rutile phase) and 45.6° (anatase phase) for the synthesized TiO2 NPs. Finally, the potential of the synthesized TiO2 NPs was assessed as an antibacterial agent and photocatalyst. The remediation of Methylene blue (MB) and Orange G (OG) dyes was carried out under UV- light and visible light for a contact time of 150–240 min respectively. The removal efficiency for 100 ppm MB dye was 25.75% and for OG dye was 72.24% under UV light, while in visible light, the maximum removal percentage for MB and OG dye was 98.85% and 80.43% respectively at 90 min. Moreover, a kinetic study and adsorption isotherm study were carried out for the removal of both dyes, where the pseudo-first-order for MB dye is 263.269 and 475554.176 mg/g for OG dye. The pseudo-second-order kinetics for MB and OG dye were 188.679 and 1666.667 mg/g respectively. In addition to this, the antibacterial activity of TiO2 NPs was assessed against Bacillus subtilis MTCC 8322 (Gram-positive) and Escherichia coli MTCC 8933 (Gram-negative) where the maximum zone of inhibition in Bacillus subtilis MTCC 8322 was about 12 mm, and for E. coli 16 mm.
