“…These include traditional extraction techniques (e.g., infusion, decoction or maceration) [2,3], modern extraction techniques (e.g., hydrodistillation, supercritical CO 2 , centrifugation) [4,5] and Water 2023, 15,1984 2 of 14 others. The proper extraction method is chosen accordingly to the characteristics of the raw material, as well as those of the desired end products (e.g., proteins, essential oils and total sugars) [6], and their uses in the different fields, such as medical (e.g., preparation of drugs) [7], parachemistry (e.g., manufacturing of cosmetics) [8] and environmental (e.g., water treatment) uses [9,10].…”

The present work sheds light on the potentiality of proteins extracted from oak (Quercus robur) leaves to treat both drinking water and industrial oily wastewater. The work was structured in three steps: firstly, oak leaves in powder form were analyzed by FTIR, XRD and SEM, thus showing the presence of proteins acting as bio-coagulants; secondly, an experimental design was conducted. According to the design of experiences based on fractional design (28−4), the highest protein concentration (4.895 mg/g) was obtained for the following operating parameters: no filtration, pH of 12, temperature of 20 °C, stirring speed of 300 rpm, stirring time of 60 min, maceration time of 4 h, centrifugation speed of 400 rpm, centrifugation time of 10 min. Finally, a jar test apparatus was used to study the effects of proteins from oak leaves on the characteristics of both drinking water and industrial oily wastewater. In drinking water, the turbidity was reduced from 15.7 to 4.82 NTU when 0.098 mg/L of oak leaves protein was added, thus satisfying the requirements of the national drinking water standards; whereas, in industrial oily wastewater turbidity, total suspended solids, chemical oxygen demand and organic matter were reduced by 96.87, 89.86, 96.39 and 46.28%, respectively, when 0.538 mg/L of oak leaves protein was added. This study opens new perspectives related to the research and development of organic coagulants applicable to industrial wastewater treatment.

“…These substances have a significant impact on plant development, stem and root elongation, seed germination inhibition, wound healing, and cell division [42,43]. The synthesis of phenolic substances takes place in the plant body through the participation of enzymes from three principal pathways of amino acid phenylalanine transformation [44]:…”

“…Keywords: Abiotic stress, antioxidant activity, berry quality, phenolics. can be classified into three main categories: phenolic, terpenoids, and nitrogen (Revutska et al, 2021). Phenolic compounds regulate plant growth and the elongation of vegetative organs such as shoots and roots, inhibiting seed germination, promoting wound healing, and controlling cell division.…”

Phenolic compounds are important indicators of grape berry and wine quality. They also have many important effects on human health. Biotic and abiotic plant stressors are the factors that affect the composition and amounts of metabolites dramatically. Although wounding is one of these stressors, little is known about its effect on the accumulation and biosynthesis of the entire phenolic profile. This study aimed to identify the effects of human-made wounding to grapevine leaves on the accumulation of grape berry metabolites in cv. ‘Cabernet Sauvignon’ grapevines. Ten combinations of different wounding timing and treatment methods were applied to 20 years old grapevine plants. The data suggests that wounding treatments have the potential to diversify the phenolic compound profile and can be utilized for their management compared to the control group. Specifically, the E15 treatment accelerated MITSS/TA by 39.83% and increased the content of trans-resveratrol by 35.78% compared to the Control. On the other hand, the E10+W5+E3 treatment resulted in a regression in maturity parameters. The wounding treatment E10+W5 increased the total phenolics by 13.74%, total anthocyanin contents by 20.48%, and transresveratrol content by 93.05%. Additionally, the E5+W3 treatment demonstrated a significant increase of 19.65% in syringic acid and 21.89% in vanillic acid contents. Although the control application for antioxidant activity reached its peak value, it decreased in the E15+W5 treatment. As a result, it was determined that the responses given to the treatments were quite diverse. Nevertheless, they also found it applicable to manage berry maturity and quality indicators. Early wounding treatments accelerate maturity, and treatments performed more recently at harvest stop berry sugar accumulation. While late treatments increase the total phenolics, the responses of the phenolic compounds profile differ
