Summary: The newly isolated Bacillus altitudinis SL7 showed efficient degradation of lignin, with optimal conditions at 40 degrees Celsius and pH 8.0. The degradation was confirmed through reductions in color and lignin contents, as well as the emergence of new low molecular weight compounds. The study suggests the potential application of B. altitudinis SL7 in biological treatment of lignin-containing effluents.

Summary: A simple anodization technique was used to synthesize Au doped TiO2 nanotubes electrodes for photoelectrocatalytic degradation of 4-CG. The optimized conditions showed 84% degradation efficiency in 6 hours. The PEC process was more effective compared to PC and EC processes. Additionally, the feasibility of using synthesized Au/TiO2NTs electrodes for large volume wastewater treatment was investigated, showing significant reduction in COD and TOC values. The cost of electrical energy consumption for both batch and recirculation mode treatments was also calculated.

Summary: Three different pulp and paper mill sludge samples from South African mills were characterized to determine their suitability for various beneficiation pathways. The characteristics of the sludge varied depending on the pulping technique, raw material, and effluent treatment used. From the analysis, it was found that different beneficiation pathways were more suitable for each type of sludge based on their specific characteristics.

Summary: This study investigated the oxidation of watered toxic waste from the pulp and paper industry in supercritical water-oxygen fluid, revealing that only CO2, CO, N2, and N2O were detected in volatile oxidation products at higher oxygen content. Increasing the oxygen ratio led to a decrease in phenols and chlorophenols produced, with 2,6-dichlorophenol and 2-chlorophenol being the most resistant to oxidation.

Summary: Over 400 million tonnes of board and paper are produced globally each year, generating 4.3-40 kg of sludge-like material, known as pulp and paper mill sludge (PPMS), per tonne of product. PPMS, with its high organic content and low toxicity, is being increasingly used as a soil amendment in agriculture. This review explores the benefits, potential impacts, and viability of land spreading PPMS, suggesting that risks can be mitigated and that the practice is environmentally responsible. However, further research is needed to assess long-term implications and the presence of emerging contaminants.

Summary: Three specific catalysts, ZIF-67, Co@NCF, and 3D NCF, were prepared and studied for the degradation of pulp and paper mill effluent using peroxymonosulfate activation. Various characterizations were used to study the properties of the catalysts. Among the prepared catalysts, 3D NCF exhibited remarkable effectiveness in generating sulfate radicals to degrade the effluent. The catalytic activity of the catalysts followed the sequence of 3D NCF > Co@NCF > ZIF-67. In the presence of 0.2 g/L catalysts, 2 g/L PMS, and at 50 degrees C, 3D NCF could degrade organic pollutants in 30 minutes at an initial COD concentration of 1146 mg/L. The degradation of the effluent using 3D NCF followed first-order kinetics with an activation energy of 40.54 kJ mol(-1). Overall, the 3D NCF/PMS system shows promising performance for the removal of pulp and paper mill effluent.

Summary: The study demonstrated that organic sludges from the pulp and paper industry can improve soil fertility and reduce erosion in agricultural soils. Although the application of these organic amendments had minimal effects on cereal yield and quality, it significantly altered the fungal and bacterial composition in the soil. Additionally, the amendments were effective in reducing suspended solids and total phosphorus concentrations in percolation water, even four years after application.

Summary: This study compared the effects of pulp and paper mill effluent and betulin on various aspects of testicular physiology in zebrafish, indicating that the alterations may be due to the actions of betulin. Exposure to both effluent and betulin led to decreased lactate and calcium influx, possibly through the activation of the NCX pump. Additionally, betulin treatment resulted in increased ROS, GSH content, GST activity, and a tendency towards decreased CAT activity in the testes.

Summary: In this study, a concurrent fixed-bed dual technology was used to remove color from tertiary treated agro-based paper & pulp industry effluent. The prepared Fe-TiO2 composite showed great potential as a durable and efficient catalyst, with 5-10% activity reduction after 50 recycles. The dual process of photocatalysis and photo-Fenton exhibited high color removal efficiency, and the optimal conditions were identified through process optimization. The findings suggest that this innovative technology can be a promising tertiary treatment option for industrial wastewater treatment systems.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
