“…This factor significantly impacts the solubility, reactivity, and charge density of chitosan 7 .One of the most intriguing properties of chitosan is its antibacterial activity. However, there is still a need to enhance its antibacterial properties to further broaden its potential applications, and is a commonly studied topic among researchers [8][9][10][11] .…”

“…In the past, have been studied different compounds that can act synergistically with chitosan to create a more potent antibacterial agent, and also offer the potential for a wider spectrum of antibacterial activity against different types of bacteria, such as silver nanoparticles 10,12 , essential oils 13,14 , quaternary salts 15 and plant extracts 16 , ursolic acid 17 among others. Ursolic acid and chitosan adducts have been relatively less studied, especially chitosan fibres and ursolic acid compounds.…”

Over the years, chitosan has been the subject of numerous studies and has gained significant popularity as a biomaterial due to its various characteristics, including biocompatibility, biodegradability, and bioactivity. In this work, chitosan fibres surface was modified with ursolic acid to improve their antibacterial properties by wet impregnation method. Five specimens of chitosan fibres were immersed in ursolic acid (UA) solution for varying immersion times of 1, 2, 4, 6, and 8 hours. Characterization was carried out by means of FTIR, SEM, UV-Vis spectroscopy; the results indicated an ongoing chemical reaction between chitosan and ursolic acid resulting in changes to the chemical structure. After 2 hours, the absorbance ratio remained constant; suggesting that the reaction had reached completion and the chemical structure of the sample remained stable. Antibacterial tests were performed on the resulting chitosan fibres against two bacterial strains. The fibres without ursolic acid did not exhibit any noteworthy antibacterial activity against either strain. However, the chitosan fibres modified with ursolic acid showed significant and almost strong antibacterial activity against the Gram-positive strain, S. aureus. These results suggest that chitosan fibres modified with ursolic acid could have potential applications as antibacterial materials, particularly against Gram-positive bacteria.

The paper aims to present the main tendencies on the global and European natural polymer markets in recent years from the point of view of the requirements and achievements of the European Commission that have been expressed in recent programs and Strategies, with special reference to the Circular Economy New Action Plan and the European Green Deal—the EU Strategies for Climate Neutrality. Natural polymers play an important role among biodegradable products whose role in the production and international trade has been systematically increasing, especially since the middle of the last decade of the new century (2015). Natural polymers are also recommended by the EU from the point of view of their specific importance in the group of biodegradable products.
