In this study, novel wheat gluten (WG)/cloisite 30B (C30B) organoclay–based bionanocomposite (BNC) films were prepared by solution casting method at various C30B concentrations (5%, 10%, and 15%). X-ray diffraction and field emission scanning electron microscopy revealed intercalation/exfoliation of C30B sheets into the WG matrix. WG-C30B 10% film was thermostable. It showed low surface roughness along with higher water barrier properties and surface hydrophobicity. The tensile strength values of WG and WG-C30B 10% films were found to be 0.7 ± 0.02 and 1.11 ± 0.01, respectively, indicating improvement in mechanical properties. WG-C30B 10% film demonstrated antibacterial activity against both <i>Staphylococcus aureus</i> and <i>Salmonella enterica</i>. Shelf life of green grapes was monitored under different conditions: 4 °C, ambient conditions, and 42 °C. WG-C30B 10% film proved effective in extending shelf life up to 18 days under ambient conditions. More than 50% of the bionanocomposite films were degraded in agricultural soil within 2 weeks, while completely degraded in sewage sludge soil after a few days. WG-C30B 10% film appeared to be promising regarding the demonstrated physico-chemical and antibacterial properties.

In the present study, (i) new insights into Congo Red toxicity were obtained using in vitro model systems and a molecular docking approach, (ii) a sustainable biosorbent from F. excelsior biomass was developed, and (iii) the detoxification potential of the biosorbent was investigated for the first time. CR application up to a concentration of 10 ppm caused a significant decrease in physiological parameters. The germination rate of H. annuus L. seeds were reduced to 60%. Moreover, significant decreases were observed in fresh weight (245 ± 0.7 mg), dry weight (25 ± 0.01 mg), root (1.8 ± 0.1 cm), and shoot lengths (3.2 ± 0.2 cm). Significant alterations in oxidant-antioxidant dynamics, including SOD, CAT, POD, and MDA, were observed after CR exposure. Additionally, increasing the CR concentration from 2 to 10 ppm caused a significant reduction in the mitotic index (14.9%) and an increase in chromosomal aberrations (4.9%) in A. cepa root cells. Molecular interactions between CR and target receptors associated with in vitro parameters (SDP1, PCK1, WRKY transcription factors, B-DNA dodecamer, CAT, POD, and SOD) were determined by molecular docking analysis. FEO biosorbent treatment significantly detoxified CR solutions, and improvements in the values of the tested physiological, biochemical, and cytogenetic parameters were observed. The biosorption process included the zero charge point, pH, initial dye concentration, biosorbent dose, stirring speed, and temperature parameters. The FEO biosorbent removed 92% of the CR from the aqueous solutions. Moreover, the Langmuir isotherm model was found to have a higher R2 value of 0.903. The correlation coefficient of the pseudo-second-order kinetic model (R2 = 0.991) was found to be higher. The process was determined as endothermic and spontaneous according to the ∆G values (- 6.36, - 4.47, - 2.59 and - 0.7 kj/mol) found in the thermodynamic studies.

The crude lignin was subjected to chemical modifications, including sulfomethylation and amination, to improve its reactivity and to increase its solubility in water. Unmodified (crude), sulfomethylated, and aminated lignin were combined with starch and then applied on the surface of test liner papers. In this study, surface, mechanical, colorimetric, and printability properties were modeled via an innovative approach called the artificial intelligence method. The effect of ratios of crude lignin, sulfomethylated and aminated lignin, and even starch portion were investigated on the paper properties, i.e., tensile strength and ring crush test (RCT) as well as optical properties, i.e., L*, a*, and b* indices and optical density and roughness of the treated handsheets by surface. The developed code can appropriately learn the non-linear behavior process and make decisions according to the pattern constructed intelligently. The paper treated with unmodified lignin exhibited an increase in the roughness value, according to the results. It was illustrated that applying a layer based on the unmodified lignin solution increased the tensile index. Also, it caused a relative increase in the tensile index of paper when a sizing solution based on sulfomethylated/aminated lignin was implemented. The value of the RCT for the paper treated with unmodified lignin and even the paper treated using the aminated lignin was as high as the treated paper just based on pure starch. There was no discernible variation in the colorimetric indices between papers treated with the black ink. The findings showed that the treatment containing pure starch had the lowest value of optical density, and the control treatment had the closest value to it.

Anaerobic fermentation of fish canning wastewater to produce volatile fatty acids (VFAs) is a promising alternative to reach this goal. This study evaluated the impact of two bioreactor feeding strategies (continuous (UASB) and sequential batch (SBR)) and two hydraulic retention times (HRT) (6 and 3 days) on VFA yield and product spectrum. The results showed that both feeding modes resulted in high VFA production, exceeding 30 g VFA-COD/L. It can be concluded that the feeding mode has no impact on VFA yield. However, it does exert a significant influence on the product spectrum. Sequential feeding was found to favor butyric acid production, with a 15% higher yield compared to continuous feeding. In contrast, continuous feeding promoted the formation of propionic and valeric acids, with yields 5% and 4% higher, respectively, than those observed under sequential feeding. In contrast, variations in HRT demonstrated no significant impact on either yield or product spectrum. These findings suggest that, for the scaling up of this valorization, the selection of feeding mode should be tailored to the desired objective.
