“…As expected, blending the polyurethanes with PLA and St increased the susceptibility of the samples to degradation. Both modifiers with a chemical structure found in the natural environment are rapidly biodegradable [ 26 , 27 , 28 ]. Despite only a small amount of them being present in the samples, both PUR 10/5 and PUR 20/5 blends degraded faster in the soil than pristine PURs.…”

A very important method of reducing the amount of polymer waste in the environment is the introduction to the market of polymers susceptible to degradation under the influence of environmental factors. This paper presents the results of testing the susceptibility to degradation in soil of branched polyesterurethane (PUR) based on poly([R,S]-3-hydroxybutyrate) (R,S-PHB), modified with poly([D,L]-lactide) (PLA) and starch (St). Weight losses of samples and changes in surface morphology (SEM, OM and contact angle system) with simultaneously only slight changes in molecular weight (GPC), chemical structure (FTIR and 1HNMR) and thermal properties (DSC) indicate that these materials are subject to enzymatic degradation caused by the presence of microorganisms in the soil. Chemical modification of branched polyesterourethanes with R,S-PHB and their physical blending with small amounts of PLA and St resulted in a slow but progressive degradation of the samples.

“…The role of these compounds is, nevertheless, not only restricted to defense: for instance, flower and fruit scents are volatile attractive signals for many pollinators and seed dispersers, thus favoring plants’ reproductive success [ 2 , 6 ]. Characterized by intense smell and high volatility, EOs unsurprisingly find their primary traditional application in perfumery, though recently their use has been expanded to many other sectors, such as food packaging, cosmetics and agricultural technology, to name but a few [ 6 , 7 , 8 , 9 ]. Such an arsenal of versatile substances represents a treasure trove for those research fields and industries geared towards the design of non-synthetic innovative products.…”

“…Depending on the intended use, different systems are being experimented in multiple research areas, including nanoparticles [ 13 ], nanocapsules [ 8 ], liposomes [ 38 ], hydrogels [ 15 ], cyclodextrins [ 39 ] and others. With regard to the conservation of paper-based items, there are a few pioneering papers, which tested three different technologies/EO-based products with the aim of to achieving empowered efficacy.…”

Archival documents and artworks stored in libraries frequently undergo degradative processes promoted by the so-called “biodeteriogens” that inhabit these places. A renewed interest in plant-derived products has arisen in those research groups focusing on cultural heritage preservation and looking for new and safe disinfection techniques. In this view, essential oils (EOs) and their volatile organic constituents are very appealing thanks to their versatility of action. A literature survey of the scientific publications involving EOs and/or their major constituents related to the conservation of paper items of cultural heritage interest is presented here, aiming to reveal benefits and limitations of such peculiar plant-derived compounds.

“…It inevitably contributes to a large degree to the destruction of microbial species owing to the leakage of vital particles from the microbial cell membrane. Numerous substances regulate drug resistance by exploiting efflux pathways of various species of gram-negative microbes (Ferreira et al, 2021). This high bactericidal activity of AgNPs is certainly due to the silver cations released from AgNPs that act as reservoirs for the Ag+ bactericidal agent (Dakal et al, 2016).…”

T HE antibacterial activity of nanoparticles and essential oil were tested against S.typhimurium, E. coli, S. aureus and B.subtilis using agar disc diffusion assays. Essential oil and nanoparticles inhibited all tested microorganisms with different concentration against S. aureus, B. subtilis, S. typhimurium and E. coli respectively. Silver and chitosan nanoparticles showed a lower inhibition for all of the tested microorganisms compared to essential oil. The present study characterized of AgNPs (~16.77nm) and ChNPs (~20.25nm) using (TEM) and GC/MS to measure chemical components of cumin and marjoram essential oils. Gamma.-Terpinene accounts for 25.54 % of total chemical components in cumin essential oil and Bis (2-ethylhexyl) phthalate accounts for 24.48 % of total chemical components in marjoram essential oil. Fish fillets inoculated were analyzed for B. cereus and E. coli during cryopreservation. Results demonstrate that cumin essential oil at 500 ppm is more active than marjoram essential oil at 500 ppm, ChNPs 1% and AgNPs 40µg/ml respectively when compared to the control. These results revealed by increased storage time were decreased microbial growth in fish fillets inoculated with B.cereus were more active than fish fillets inoculated with E. coli.Therefore, the application of nanoparticles and essential oil has a good potential to be antimicrobial activities for various food applications.
