Summary: This study demonstrates a sustainable approach to fabricate iridescent materials resembling absorbing pigments using cellulose nanocrystals (CNCs) from waste biomass. The CNCs are mixed with polyvinylpyrrolidone (PVP) to create composite films, which can then be ball-milled to produce vibrant color pigments. These pigments utilize the inherent optical properties of cellulose, offering a more eco-friendly alternative to traditional dyes.

Summary: This study investigated the direct dissolution and joint spinning of cellulose and lignin from NMMO-water, showing that lignin can dissolve in a range from 30% NMMO to 70% NMMO. Dry-jet wet spinning was achieved for cellulose-lignin compound up to 50% lignin loading, with lignin mainly acting as a filler in the core region of the fiber. The spinnability decreases with increasing lignin content.

Summary: Understanding the relationship between cellulose fiber morphology and the rheological behavior of its dispersions is important for optimizing their applications. Sugarcane bagasse-sourced cellulose dispersions with different numbers of high-pressure homogenization cycles were produced. Microfluidization produced cellulose nanofibers with similar surface charge densities and crystallinities. The rheological properties of the dispersions could be tuned by adjusting the length of the nanofibers, allowing for targeted applications.

Summary: The study proposes a biorefinery configuration for the co-production of ethanol, xylitol, lignin, and cellulose acetate from lignocellulosic biomass, analyzing economic viability and environmental impact in low sugarcane availability scenarios. Results showed that ethanol, xylitol, and cellulose acetate production can be economically viable only if lignin is considered as a product. Additionally, the carbon capture capacity of about 400 kg per tonne of sugarcane included in the process was determined.

Summary: Global warming and greenhouse gas emissions are significant concerns of the modern world. The cement industry causes a substantial amount of CO2 emissions, but cement is still necessary for future societal development. Geopolymers, with natural fiber inclusion, offer a promising alternative with significantly lower emissions than Ordinary Portland Cement. A lifecycle assessment of a geopolymer composite containing pre-treated fibers revealed that the low liquid ammonia treated sugar cane bagasse fiber geopolymer had the best environmental performance, with 857.9 kg CO2 equivalent emissions per 1 m3 of pure binder.

Summary: Food and feed contamination by fungi, especially toxigenic ones, is a global concern. Lactic acid bacteria (LAB) have been gaining attention for their antifungal and anti-mycotoxin properties. This study tested 14 LAB strains isolated from naturally fermented Brazilian table olives for their ability to inhibit the growth of certain fungi and reduce mycotoxin production. The results showed that certain LAB strains exhibited strong antifungal activity and reduced the production of mycotoxins such as Aflatoxin B1, ochratoxin A, and patulin. These findings demonstrate the potential of LAB strains as natural agents to control toxigenic fungi and their mycotoxins in fermented products.

Summary: Microalgae are a sustainable and renewable source for various compounds used in industries such as cosmetics, food, and pharmaceuticals. However, their commercialization faces challenges due to low biomass and productivity. Strategies to enhance cost-effectiveness in microalgae cultivation focus on optimizing nutrient needs and environmental factors. Genome-scale metabolic (GSM) models aid in understanding metabolic processes and can be used to optimize compound and biomass production. This review provides an overview of key considerations and strategies in microalgae cultivation, emphasizing the use of GSM models for in silico-guided optimization.

Summary: The aim of this study was to develop a yogurt fortified with curcumin by encapsulating it in solid lipid nanoparticles (SLNs). The incorporation of curcumin-loaded SLNs did not significantly affect the pH and titratable acidity of the yogurt during its shelf-life. However, the yogurt with SLNs showed slightly higher syneresis values and a stronger yellow color compared to the control. Overall, the addition of curcumin-loaded SLNs did not impact the physicochemical and rheological stability of yogurt during shelf-life, indicating a promising application for the development of new functional foods.

Summary: Microalgae have gained attention as a promising feedstock for healthier food products, but high production costs and low productivities remain a challenge. This study used a two-step optimization strategy to maximize biomass production of a Chlorella vulgaris strain under heterotrophic conditions. After studying 24 variables, (NH4)2SO4, MgSO4middot7H2O, and C6H12O6 were identified as factors with a significant impact on biomass concentration. Optimization of the culture medium led to a 99.6% increase in biomass and a 48.0% increase in carbohydrate production.
