Summary: This study found that metal-free biochar derived from water hyacinth combined with calcium peroxide can effectively degrade 4-nonylphenol-contaminated sediments. The degradation mechanism is mainly attributed to the reactive species and active sites on the biochar surface, as well as the ability of the carbon framework to shuttle electrons.

Summary: The uncontrolled release of harmful endocrine disruptors (EDs) is causing serious damage to human and animal health. A biosensor called Lac/PAA/CFP, which immobilizes laccase over electropolymerized poly anthranilic acid on a carbon fiber paper (CFP) electrode, was developed for the detection of p-nonylphenol (PNP), a persistent phenolic endocrine disruptor and a harmful eco-toxic pollutant. The biosensor showed good selectivity and a low limit of detection for PNP in real water samples.

Summary: Obesity is a multifactorial disease caused by genetic and environmental factors. Overeating and lack of exercise are common causes, but environmental substances known as obesogens can also disrupt the balance of energy intake and expenditure, increasing the risk of obesity. Obesogens primarily affect the development and function of adipose tissue, liver, pancreas, gastrointestinal tract, and brain, altering the control of metabolism. The most sensitive period for obesogen exposure is in utero and early childhood, which may lead to changes in gene expression that can be transmitted to future generations.

Summary: In this research, the synthesis and utilization of novel-shaped silver oxide nanoblades (Ag2O NBs) for direct electrochemical sensing of 4-hydroxybenzoic acid (HBA) were reported for the first time. The synthesized Ag2O NBs exhibited excellent electrocatalytic competence and oxidation capability towards HBA. A standardized cyclic voltammetry (CV) technique was successfully optimized for the determination of HBA content, and the fabricated sensor showed high sensitivity and selectivity. The practicality of the sensor was demonstrated through analysis of various field samples.

Summary: This study presents an efficient method for remediating DEHP-contaminated marine sediments using water hyacinth biochar (WHBC) as a carbocatalyst activated by calcium peroxide (CP). The catalytic capacity of WHBC was significantly influenced by the pyrolysis temperature. The WHBC/CP system achieved a 94% removal of DEHP, with singlet oxygen (1O2) and electron-rich carbonyl functional groups playing crucial roles in the non-radical activation of CP. Moreover, WHBC showed lower cytotoxicity in HepG2 cells and induced cell cycle arrest at the G2/M phase.

Summary: The urgent demand for alternative energy sources is due to the burden on fossil fuels and resulting energy crisis and climate change. Lignocellulosic biomass is a renewable and alternative bioresource for energy generation. Different pretreatment strategies have been established to overcome biomass recalcitrance, and biological pretreatment using microbial enzymes is a promising method. Cellulases, hemicellulases, and ligninolytic enzymes have numerous industrial applications. This review provides a detailed description of these enzymes and their prospective applications in lignocellulosic biomass valorization. Solid state fermentation and enzyme immobilization strategies are discussed, along with future prospects.

The introduction of NB-LGBC/CP significantly improved the degradation of 4-NP through a synergistic interaction and electron transfer. Furthermore, the NB-LGBC/CP treatment enriched specific bacteria, Desulfonatronum within the Proteobacteria phylum, in the WAS, enhancing the biological treatment capacity of 4-NP. Therefore, NB-LGBC shows great potential as a novel approach for decontamination of WAS.

Summary: Biorefinery is a promising alternative to petrorefinery for sustainable development, with lignocellulosic biomasses as the most important raw material. Enzymatic conversion of biomasses into bioethanol is considered the most sustainable method, but biomass recalcitrance presents a major challenge. Pretreatment targeting lignin, the main contributor to recalcitrance, is necessary to make cellulose and hemicellulose more accessible to enzymes. Laccase, a lignin-degrading enzyme, is a potential option for biological pretreatment, although its slow reaction rate is a limitation. This article provides insights into biorefinery and emphasizes the significance of laccase.

Summary: Bioactive peptides derived from fish byproduct protein hydrolysate have vast potential as functional food ingredients. Enzymatic hydrolysis is the preferred method for the preparation of these peptides due to its high specificity, mild reaction conditions, and lack of residual organic solvents. However, the use of proteases and the availability of food-grade enzymes pose limitations. Current research focuses on the purification and identification of these peptides, as well as their bioactivities, including antiproliferative, antimicrobial, antihypertensive, antiglycemic, antitumor, and antioxidative functions. The growing interest in proteomics and the utilization of marine and aquatic waste stems from the bioactivity and sustainability of these products.

Summary: The effect of pyrolysis atmosphere (CO2 or N2), pyrolysis temperature (300-900 degrees C), and heteroatom (N, B, O, P, NP, or NS) doping on the content of polycyclic aromatic hydrocarbons in pineapple leaf biochar was investigated. Without doping, the highest polycyclic aromatic hydrocarbon production (1332 +/- 27 ng/g) was observed in CO2 at 300 degrees C, while the lowest (157 +/- 2 ng/g) was observed in N2 at 700 degrees C. The main components, naphthalene and acenaphthylene, accounted for about 91% of the total polycyclic aromatic hydrocarbon in biochar produced under CO2 at 300 degrees C. Doping significantly reduced the total hydrocarbon content, with reductions of 49% (N), 61% (B), 73% (O), 92% (P), 93% (NB), and 96% (NS) under the conditions of maximal polycyclic aromatic hydrocarbon production (CO2, 300 degrees C). The findings highlight the importance of controlling pyrolysis atmosphere, temperature, and heteroatom doping for the management of polycyclic aromatic hydrocarbons in biochar production and contribute to the development of circular bioeconomy.

Summary: The increasing concerns about climate change and the overexploitation of non-renewable resources have led to the need for alternative renewable and eco-friendly resources for the production of innovative materials, achieving the goals of bioeconomy. Lignocellulosic biomass (LB), derived from plant-based agro-industrial food waste and crop residues, can be utilized for the production of various value-added chemicals and bioproducts. Cellulose, derived from LB, is the most abundant natural and biodegradable organic polymer, with wide-ranging applications in lignocellulosic biorefineries and food industries. However, the extraction of cellulose from LB is challenging due to the recalcitrant nature of biomass. A suitable cellulose extraction method through LB fractionation is necessary to improve cellulose yield. Nanocellulose (NC) has great potential and researchers are interested in developing environmentally friendly cellulose extraction methods. Cellulose nanofibrils and nanocrystals have excellent mechanical properties, non-toxic characteristics, and biodegradability, making them suitable for diverse industrial sectors. This review emphasizes the potential role of cellulose extraction and NC production from agro-food waste, discusses different pretreatment methods for cellulose extraction from LB, and highlights the applications and future directions of cellulose and NC-based commercial products.
