Summary: In this study, natural extracts from coffee, cocoa, or cinnamon were added to a polycaprolactone matrix as anti-aging compounds. The performance of these extracts was compared to a retail anti-aging compound. Results showed that lower concentrations of the tested extracts were advantageous, with no negative impact on material properties observed at content below 1 wt.%. The stabilizing performance of the extracts during accelerated aging was mostly similar to or better than the reference compound used.

Summary: The mechanical properties of pectin films can be enhanced by incorporating polyphenol-rich fruit extracts. The presence of high levels of sugars and polyphenols in the extracts increases the tensile strength and moisture content of the films, while the composition of sugars, acids, and polyphenols influences the elongation at break of the films. The structures and concentrations of anthocyanins and flavonoids also play a significant role in determining the elongation at break differences. The mechanical properties of pectin-based films can be tailored for specific applications in food packaging by adjusting the concentrations of sugars, organic acids, and polyphenols.

Summary: Plant extracts and essential oils possess a variety of molecules that have potential applications in medicine, the food industry, and cosmetics. Furthermore, these plant derivatives show promising activity in antitumor, antifungal, anti-inflammatory, and bactericidal effects. Different methodologies are needed to optimize the extraction, purification, and characterization of these biomolecules. Moreover, these plant products can be used in the synthesis of nanomaterials to reduce the harmful effects of conventional synthesis routes and combine the properties of nanomaterials with those present in extracts and essential oils.

Summary: This study explores the current application of medicinal plant extracts in drug dosages to control microbial biofilms in the oral cavity. Plant species such as Camellia sinensis, Melaleuca alternifolia oil, and Azadirachta indica extracts show potential in reducing dental plaque and improving periodontal parameters. However, further studies are necessary to fully understand the clinical relevance of their application in treating oral biofilm-associated infections.

Summary: The aim of this study was to evaluate the effect of a CAs-rich stream derived from acidogenic mixed culture fermentation of acid whey on PHAs synthesis by Paracoccus homiensis and compare it with individual synthetic CAs. The results showed that the CAs-rich stream promoted the growth of Paracoccus homiensis and increased the production of PHAs. These findings are important for the development of a microbial PHAs production as part of an integrated valorization process.

Summary: The production of polyhydroxyalkanoates (PHAs) by Aeromonas sp. AC_01 using short and medium chain fatty acids (SMCFAs) was investigated. The results showed that the bacterial strain was able to grow and synthesize PHAs using SMCFAs. The highest PHA productivity was observed when a mixture of acetic acid and butyric acid was used as a supplement. Additionally, the strain was capable of synthesizing novel copolymers with high fractions of 3-hydroxybutyrate (3HB) and 3-hydroxyvalerate (3HV), which exhibited high thermal resistance. These findings suggest that Aeromonas sp. AC_01 is a promising candidate for the biotechnological production of PHAs from SMCFAs.

Summary: This study evaluated the use of short- and medium-chain fatty acids (SMCFAs) derived from acid whey fermentation for polyhydroxyalkanoate (PHA) production. Pseudomonas sp. GL06 showed the highest tolerance to SMCFAs and produced PHAs with the highest productivity. Further research revealed that PHA monomeric composition varied with bacterial strain and growth medium. The copolymer made of 3-hydroxybutyric, -hexanoic, -octanoic, -decanoic, and -dodecanoic exhibited promising properties.

Summary: This study compared the laser ablation characteristics of commonly used thermoplastic materials and analyzed the impact of surface layer modification on surface free energy, wettability, and adhesive strength. The results showed that ABS, PS, PET, and PC had higher laser ablation dynamics than PLA and PA6. Surface modification significantly increased the adhesive strength, and near-infrared laser radiation was effective for surface layer modification and marking of ABS and PS materials.

Summary: The study aims to manufacture PCL-based biodegradable composites with high concentration of calcium carbonate (CC) and analyze the changes in properties caused by different amounts of CC. A relatively cheap and unmodified kind of CC is used to determine the cost change of the composites. Qualitative and quantitative analyses, as well as structure analysis, are conducted to investigate the distribution and dimensions of filler particles in the composites. Mechanical, thermal, and economic analyses are also performed. The results show that CC significantly affects the mechanical properties of PCL, reducing its elongation at break and impact strength while increasing flexural modulus and bending strength. The thermal stability of the composites is improved, but phase transition temperatures and crystallinity do not change significantly. Increasing CC content leads to a significant decrease in the unit price of the composites, which is important for obtaining low-cost materials with new properties.

Summary: This study examined the impact of commercially available food preservatives on the antimicrobial properties of LDPE film commonly used for food packaging. The results showed that adding 3% Natamax((R)) or 5% Nisaplin((R)) effectively protected the LDPE film from microbes. The addition of these biocides did not significantly affect the strength and rheological properties of LDPE, but there were changes in the optical properties.
