Summary: This study evaluated the use of greener precipitating agents (methane sulfonic acid, formic acid, and lactic acid) to produce lignin bioactive extracts from sugarcane bagasse and straw alkaline black liquors, replacing sulfuric acid commonly used in industry. The highest precipitation yield was achieved with lactic acid for sugarcane bagasse. The composition of the extracts varied between sulfuric acid and greener precipitating agents, particularly in terms of sugar content. The results suggest organic acids, especially formic acid, as promising alternatives to recover lignin bioactive extracts instead of conventional sulfuric acid.

Summary: The aim of this study was to analyze the phytochemical content of Ephedra alata pulp extract (EAP) and investigate its antioxidant and anti-inflammatory capacities. High-performance liquid chromatography-electrospray ionization-quadrupole-time-of-flight mass spectrometry (HPLC-ESI-QTOF/MS) was used for phytochemical analysis, and various in vitro antioxidant and anti-inflammatory tests were conducted. The results showed that EAP contains 42 metabolites, including flavonoids, sphingolipids, fatty acids, ephedrine derivatives, and amino acid derivatives. EAP exhibited strong antioxidant activity, as well as notable anti-inflammatory effects by inhibiting COX-1 and COX-2, preventing protein denaturation, and protecting membrane stabilization.

Summary: This work investigated three process configurations for the biorefinery of olive oil mill leaves (OL), which include natural antioxidants, lignin, and bioethanol. Configuration 1 achieved the simplest process but had poor biomass fractionation. Configuration 2 included ethanol extraction to enhance the recovery of natural antioxidants. Configuration 3 achieved better fractionation and the highest bioethanol production with a yield of 71% of the theoretical yield. It also generated a liquid stream with higher lignin content, facilitating the obtainment of high purity lignin.

Summary: The traditional biodiesel production model using edible oils as raw materials is unsustainable due to high costs, competition with the food sector, and environmental threats. Shifting to non-edible oils as raw materials for biodiesel production offers the opportunity for increased sustainability and avoiding conflicts with food production. Processing non-edible oilseeds generates large amounts of residues, which can be upgraded to advanced biofuels and high-value products through bioconversion. However, pretreatment is required to enhance the susceptibility of these residues to enzymes and microorganisms.

Summary: A grapevine shoot extract (GSE) containing stilbenoids, particularly trans-resveratrol and trans-epsilon-viniferin, was obtained using ultrasound-assisted extraction. GSE administration to a myocardial injury animal model showed improved plasma lipid profile, reduced plasma ion concentration disturbance, cardiac dysfunction, DNA damage, and necrosis of myocardial tissue. These effects are likely due to the antioxidant properties of GSE, increased levels of endogenous antioxidants, and decreased lipid peroxidation markers in the heart. The study also demonstrated ACE-inhibitory activity, indicating the potential of GSE in cardiovascular disease prevention. Our findings suggest that GSE, containing trans-resveratrol and its derivatives, has the potential to be used in the development of innovative functional ingredients.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
