Summary: Simultaneous inoculation of microalgae and yeast is the optimal strategy for utilizing starch processing effluent for biofuel feedstock production. Under the optimal conditions, the lipid yield and carbon-conversion ratio of the co-fermentation reached 1.81 g/L and 82.53%, respectively, which were higher than those of the monoculture model. Co-fermentation of microalgae and yeast in starch processing effluent is a promising and applicable strategy for wastewater remediation and low-cost biofuel feedstock production.

Summary: Municipal mixed plastic waste (MMPW) recycling is an innovative approach to convert environmental waste into energy fuels, particularly plasto-oil. The study investigates the performance of plasto-oil blended with diesel fuel in a PCCI-mode diesel engine. The results show that PCCI combustion reduces carbon monoxide and nitrogen oxides emissions, although the thermal braking efficiency is slightly diminished. Additionally, the blend of plasto-oils decreases CO and unburned hydrocarbon emissions at higher engine loads.

Summary: Global warming is caused by the increase of atmospheric carbon dioxide levels, which requires sustainable methods to capture carbon. This review focuses on carbon capture, usage, and storage with microalgae, highlighting methods to enhance carbon dioxide uptake, combining wastewater and flue gases, using machine learning for strain identification, implementing artificial intelligence and automation, and promoting the circular bioeconomy. Various techniques, such as modified photobioreactors, membranes, chemical methods, solvents, adapted strains, genetically engineered strains, omics, and nanotechnology, can improve the carbon dioxide uptake by microalgae. Furthermore, the economic viability of microalgae-based carbon capture and bioenergy production is discussed. On average, cultivating microalgae on 13 million acres of land can sequester approximately 0.5 gigatons of CO2 and generate over 300 tons of biomass.

Summary: In this study, the inhibitory potential of four major catechins (EC/EGC/ECG/EGCG) against CCL2-regulated monocyte/macrophage recruitment was assessed. Catechins with the gallate moiety (ECG/EGCG) specifically attenuated CCL2-induced macrophage migration by binding to a pocket on CCL2. The molecular specificity/stability of CCL2-catechin complexes was regulated by multiple factors, including stereospecificity, hydroxyl groups, carbonyl group positioning, and galloylation.

Summary: This review summarizes the role of omega-3 and omega-6 fatty acids, determined by chain length, saturation degree, and position of double bonds, in human health. It highlights oleaginous microalgae as a reliable, economical, and sustainable source of these fatty acids. Humans cannot synthesize these fatty acids and need to absorb them through the diet. The demand for microbial omega-3 fatty acids is increasing due to the growing prevalence of cardiovascular diseases and changing dietary preferences. The importance of a healthy immune system, especially following the COVID-19 pandemic, has further strengthened the market for omega-3 fatty acids.

Summary: In this study, p-cymene-loaded gellan gum (GA)/poly(vinyl alcohol) (PVA) nanofibers with strong antibiofilm activity against Candida albicans and Candida glabrata were prepared using electrospinning. In vitro biocompatibility assay showed no cytotoxicity to NIH3T3 cell lines. In vivo, the nanofibers promoted faster healing of skin lesions compared to traditional clotrimazole gel without scarring. These findings suggest that p-cymene-loaded GA/PVA nanofibers are an effective biomaterial for cutaneous tissue regeneration.

Summary: With the industrial revolution, the accumulation of persistent organic pollutants (POPs) in the environment has become common. These POPs, which are organic molecules containing halogens, have a high affinity for biological macromolecules such as nucleic acids, proteins, and lipids, leading to toxic effects in living organisms. This review provides a comprehensive understanding of the structural and molecular aspects of protein-POP interactions, identifying five major protein targets and highlighting the role of H-bonds, van der Waals, and hydrophobic interactions in the formation of protein-POP complexes. The interaction between POPs and proteins can alter protein conformation and modulate cellular signaling processes, ultimately leading to various pathological conditions.
