“…In this regard, it became necessary to create packaging materials with antimicrobial properties, which remains relevant today. Today there are many developed antimicrobial polymeric materials [ 14 ], where substances of natural origin [ 15 , 16 , 17 ] and synthetic origin [ 18 ], including nanoparticles [ 19 , 20 ], act as antimicrobial components. Modification of PBAT will make it possible to obtain biodegradable packaging materials with antimicrobial properties [ 21 ].…”

Particular attention is paid to biodegradable materials from the environmental point of view and antimicrobial materials that ensure the microbiological safety of packaged products. The aim of the work was to study the properties of the composition, based on biodegradable polybutylene adipate terephthalate (PBAT) and the antimicrobial additive—birch bark extract (BBE). Test samples of materials were obtained on the laboratory extruder by extrusion with ultrasonic treatment of the melt. The concentration of the antimicrobial additive in the polymer matrix was 1 wt %. A complex research was carried out to study the structural, physico–mechanical characteristics, antimicrobial properties and biodegradability of the modified PBAT. Comparative assessment of the physico–mechanical characteristics of samples based on PBAT showed that the strength and elongation at break indices slightly decrease when the ultrasonic treatment of the melt is introduced. It was found out, that the antimicrobial additive in the composition of the polymer matrix at the concentration of 1 wt % has a static effect on the development of microorganisms on the surface of the studied modified films. Studies of the biodegradability of modified PBAT by composting for 4 months have shown that the decomposition period of modified materials increased, compared to pure PBAT. The developed modified polymer material can be recommended as an alternative replacement for materials based on polyethylene for food packaging.

The study aims to synthesize and examine the biological activity of mono- and binuclear platinum (II) and palladium (II) complexes containing terminal and bridging nitrite ligands against the test cultures of Bacillus subtilis B4647, Aspergillus brasiliensis (niger) F679, Pseudomonas aeruginosa B8243, and Escherichia coli. Through the interaction of mononuclear platinum (II) and palladium (II) complexes, dimeric complexes having nitrite ligands were synthesized. The composition and structure of these complexes were established using elemental analysis, conductometry, potentiometry, cryoscopy, infrared spectroscopy, X-ray diffraction analysis, and X-ray fluorescence analysis. A way to coordinate nitrite ligands with the central atom was established. Antimicrobial and antifungal properties were evaluated according to the capability of the synthesized complexes to inhibit the activity of bacteria and fungi via diffusion in agar and in vitro dilution. The minimum inhibitory and bactericidal concentrations of the complexes suppressing the visible growth of microorganisms and fungi, as well as exhibiting their bactericidal effect, ranged from 62.5–125 μmol/dm3. The obtained results revealed a high activity of the palladium (II) binuclear complex of the non-electrolytic type and the platinum (II) binuclear complex of the cationic type. Unlike mononuclear complexes, palladium and platinum binuclear complexes demonstrate higher antibacterial activity. Antibacterial effectiveness exhibited by the palladium complex of the non-electrolytic type against bacteria Bacillus subtilis and Escherichia coli, as well as fungi Aspergillus niger, is more pronounced. The only exception is the antimicrobial activity of the palladium complex against Pseudomonas aeruginosa, which is comparable to that of the binuclear platinum complex of the cationic type. By changing the structure of the complex, the composition and charge of the inner sphere, the number of coordination centers, as well as the nature and denticity of ligands, it is possible to achieve a higher toxic effect of the complexes against bacteria and fungi.
