“…According to Marín et al [68], the antimicrobial properties of natural matrices are usually associated with the presence of dietary polyphenols that are metabolized by gut microbiota into simple bioactive compounds with diverse effects. The studies of Wolny-Koładka et al [74] and Roy et al [75] also suggested using the waste from parsley leaves or stems to produce silver nanoparticles with significant antimicrobial effects against Klebsiella pneumonia, S. aureus and Escherichia coli.…”

In the present study, the chemical profile and bioactive properties of the roots of turnip-rooted parsley (Petroselinum crispum spp. tuberosum) germplasm were evaluated. For this purpose, plants from seventeen parsley cultivars were grown in 6 L pots, and the obtained roots were analyzed in terms of nutritional value, chemical composition (tocopherols, sugars and organic and fatty acids) and bioactive content (antioxidant activity, phenolic compound composition and antimicrobial properties). Our results showed great variability in terms of the chemical composition and bioactive properties of root parsley germplasm. A higher fresh root yield was recorded for the common “Root parsley” common variety (164 g/pot), followed by the varieties “Osborne” (109 g/pot), “Sonata” (104 g/pot), “Kaśka” (104 g/pot) and “Halblange Berlinska” (103 g/pot), whereas the lowest yield was recorded for the “Hanacka” variety (69 g/pot). A significant variation was also observed in the nutritional value parameters: the roots of the “Sonata” genotype showed the highest fat content; “Arat”, “Osborne” and “Olomuńcka” had the highest ash content; the “Alba” cultivar contained significantly higher amounts of carbohydrates; and the “Vistula” cultivar showed the highest energetic value. The only detected isoforms of vitamin E were α- and δ-tocopherols; content varied depending on the cultivar, although α-tocopherol was the most abundant compound in most cultivars, especially in the “Arat” cultivar. Sucrose was the most abundant free sugar detected, especially in the “Sonata” cultivar (16.96 g/100 g dw), followed by apiose (2.93–5.55 g/100 g dw), glucose (1.3–3.47 g/100 g dw) and fructose (1.37–3.03 g/100 g dw). Moreover, malic acid was the most abundant organic acid in most of the tested cultivars. Twenty-one individual fatty acids were identified in all the studied cultivars, with linoleic (47.9–57.1%) and palmitic acid (20.66–20.5%) being the most abundant. Nineteen individual phenolic compounds were tentatively identified, including three phenolic acids, fourteen flavonoids and two hydrolyzable tannins, while apigenin-O-pentoside-O-hexoside was the most abundant. The antioxidant activity differed between the tested assays (TBARS and OxHLIA), and the most effective cultivars for the TBARS assay (“Root parsley (common variety)” and “Berlinski Halblange Springer”) were those with the lowest antioxidant activity for the OxHLIA assay after 120 min. Finally, in most cases, the root extracts were more efficient or similarly effective compared to the positive controls against the tested bacteria and fungi. In conclusion, our results provide information regarding the chemical characterization and the bioactivities of the roots of turnip-rooted parsley germplasm that could be further exploited in sustainable and diversified agro-ecosystems through the introduction of this species as a novel/complementary crop in the traditional farming systems of the Mediterranean basin.

“…Nevertheless, the attainment of silver nanoparticles depends on numerous factors, such as the genetic properties of the organisms or the environmental conditions [11]. If sintering silver through this process, we could consider it a biobased material [25]. Even so, silver is a problem for submarine life and is not biodegradable, becoming a problem for the environment [18].…”

In the last decades, the demand for electronics and, therefore, electronic waste, has increased. To reduce this electronic waste and the impact of this sector on the environment, it is necessary to develop biodegradable systems using naturally produced materials with low impact on the environment or systems that can degrade in a certain period. One way to manufacture these types of systems is by using printed electronics because the inks and the substrates used are sustainable. Printed electronics involve different methods of deposition, such as screen printing or inkjet printing. Depending on the method of deposition selected, the developed inks should have different properties, such as viscosity or solid content. To produce sustainable inks, it is necessary to ensure that most of the materials used in the formulation are biobased, biodegradable, or not considered critical raw materials. In this review, different inks for inkjet printing or screen printing that are considered sustainable, and the materials that can be used to formulate them, are collected. Printed electronics need inks with different functionalities, which can be mainly classified into three groups: conductive, dielectric, or piezoelectric inks. Materials need to be selected depending on the ink’s final purpose. For example, functional materials such as carbon or biobased silver should be used to secure the conductivity of an ink, a material with dielectric properties could be used to develop a dielectric ink, or materials that present piezoelectric properties could be mixed with different binders to develop a piezoelectric ink. A good combination of all the components selected must be achieved to ensure the proper features of each ink.

“…This technique involves production of NPs using biological resources, which effectively overcomes the drawbacks imposed by physical and chemical methods [29]. A few examples include Cu NPs from seeds of Illicium vercium (star anise) and Mysristica fragrans (nutmeg) [30], Ag NPs from agricultural wastes [31] and extracts of red currant and bilberry wastes [32]. Being eco-friendly, this approach does not require the involvement of noxious chemicals and extreme conditions.…”

Advanced agronomic methods, urbanisation, and industrial expansion contaminate air, water and soil, globally. Agricultural and industrial activities threaten living biota, causing biodiversity loss and serious diseases. Strategies such as bioremediation and physiochemical remediation have not been effectively beneficial at treating pollutants. Metal-based nanoparticles (NPs) such as copper, zinc, silver, gold, etc., in various nanoformulations and nanocomposites are used more and more as they effectively resist the uptake of toxic compounds via plants by facilitating their immobilisation. According to studies, bio-based NP synthesis is a recent and agroecologically friendly approach for remediating environmental waste, which is effective against carcinogens, heavy metal contamination, treating marine water polluted with excessive concentrations of phosphorus, nitrogen and harmful algae, and hazardous dye- and pesticide-contaminated water. Biogenic resources such as bacteria, fungi, algae and plants are extensively used for the biosynthesis of NPs, particularly metallic NPs. Strategies involving green synthesis of NPs are nontoxic and could be employed for commercial scale production. Here, the focus is on the green synthesis of NPs for reduction of hazardous wastes to help with the clean-up process.
