The growing global emphasis on sustainable agriculture has brought increased attention to the health and productivity of soils, especially through the lens of soil microbiology. Microbial communities in soil are essential for nutrient cycling, organic matter decomposition, and maintaining overall soil health. However, agricultural practices, including synthetic fertilizers and intensive farming, have led to short time impacts in these microbial ecosystems, potentially threatening soil fertility and environmental quality. Agricultural expansion and food production generate waste and chemical inputs, such as heavy metals, pesticides, and herbicides, leading to significant environmental contamination. This scenario requires the implementation of remediation strategies that are both sustainable and energy efficient. In this context, microbiological processes present a much promising approach to mitigating the environmental impacts of soil pollution. Techniques such as bioremediation, which harness the natural metabolic capabilities of soil microorganisms, and bioaugmentation, which involves the introduction of specific microbial strains to increase degradation processes, are being explored. These approaches are vital for restoring soil health, contributing to environmental conservation and soil biodiversity, improving nutrient cycling, and promoting long-term agricultural productivity.

The utilization of membrane technologies in winemaking has revolutionized various stages of production, offering precise and efficient alternatives to traditional methods. Membranes, characterized by their selective permeability, play a pivotal role in enhancing wine quality across multiple processes. In clarification, microfiltration and ultrafiltration membranes, such as ceramic or polymeric membranes (e.g., polyethersulfone or PVDF), effectively remove suspended solids and colloids, resulting in a clearer wine without the need for chemical agents. During stabilization, membranes such as nanofiltration and reverse osmosis membranes, often made from polyamide composite materials, enable the selective removal of proteins, polysaccharides, and microorganisms, thereby improving the wine’s stability and extending its shelf life. Additionally, in dealcoholization, membranes like reverse osmosis and pervaporation membranes, typically constructed from polydimethylsiloxane (PDMS) or other specialized polymers, facilitate the selective removal of ethanol while preserving the wine’s flavor and aroma profile, addressing the increasing consumer demand for low-alcohol and alcohol-free wines. This article provides a comprehensive analysis of the advancements and applications of membrane technologies in winemaking.

The extraction of bioactive compounds, such as flavonoids and coumarins, from natural sources has gained significant attention due to their potential health benefits. This review aims to explore the application of high-pressure extraction processes, particularly supercritical fluid extraction (SFE) and pressurized liquid extraction (PLE), for obtaining flavonoids and coumarins from flower seeds. These techniques offer a greener, more efficient alternative to conventional extraction methods, minimizing the use of harmful solvents and improving the yield and purity of the target compounds. Flower seeds, a rich source of bioactive molecules, are an underutilized reservoir for these valuable compounds. For example, seeds from plants such as Calendula officinalis (calendula) and Helianthus annuus (sunflower) are rich in flavonoids and coumarins. The proposed review will examine the influence of extraction parameters—such as temperature, pressure, solvent choice, and extraction time—on the yield and quality of flavonoids and coumarins. This review aims to provide a comprehensive understanding of high-pressure extraction methods and optimize protocols for the efficient, sustainable extraction of flavonoids and coumarins from flower seeds.

The growing demand for sustainable and environmentally friendly cosmetic products has driven innovations using plant residues as raw materials for high-value-added applications. This study focuses on the enzymatic hydrolysis of plant residues to extract bioactive compounds, with the potential for application as functional ingredients in cosmetics. Enzymatic processes are highlighted for their ability to optimize extraction, preserving the bioactivity of the compounds while significantly reducing the environmental footprint compared to conventional resource-intensive methods. This work emphasizes scientific articles that incorporate the principles of the circular economy, promoting the reuse of solid waste and mitigating the need to extract new natural resources. The valorization of waste through advanced biotechnological technologies addresses critical environmental challenges and offers innovative solutions that transform agro-industrial by-products into high-value inputs for the cosmetic industry. The results presented reinforce this approach’s feasibility and positive impact, promoting economic and environmental benefits. This study highlights the transformative role of enzymatic hydrolysis in the transition toward a more sustainable, efficient cosmetics industry integrated with global decarbonization goals.

The immobilization of enzymes in polyamide-based polymeric materials through covalent bonding is an established technique to stabilize and reuse biocatalysts in industrial processes. Traditionally, enzymes are immobilized using crosslinking agents that activate functional groups on both the support and the enzyme, creating strong bonds that securely anchor the enzyme to the surface. While effective for maintaining enzyme activity over multiple cycles, this method can reduce catalytic efficiency due to rigid binding and involves complex activation steps. Recently, in situ immobilization approaches have emerged as promising alternatives. In this method, enzymes are directly entrapped within the polymer matrix during the synthesis of the polyamide support, such as nylon, simplifying the process and offering enhanced control over enzyme distribution. For instance, studies have demonstrated that in situ immobilization can improve enzyme stability by protecting it within the polymeric network, while reducing production costs and waste. This review explores the ability of polyamide as a support material for immobilization of enzymes, analyzing key techniques, performance across applications, and future strategies to optimize polymer-enzyme interactions for industrial use.

The immobilization of enzymes, especially lipases, presents a significant challenge in contemporary biotechnology due to their wide-ranging application in industrial processes. Given the array of available techniques for enzyme immobilization, this study aimed to immobilize Candida antarctica B (CALB) lipase within silica xerogel and sonogel matrices obtained through the sol–gel technique. Polyethylene glycol (PEG) was incorporated as an additive, with tetramethylorthosilicate (TMOS) serving as the silica precursor. This study assessed the operational stability, storage stability, and thermal properties of the resulting supports. Results revealed that both sonogel and xerogel supports, supplemented with PEG, maintained storage stability above 50% throughout a 365-day period. Moreover, operational stability tests demonstrated that the xerogel support could be reused up to 21 times, while the sonogel support exhibited 10 reuses. Thermal analysis further highlighted a reduction in the deactivation constant and an elongation of the half-life time for both supports. These observations suggest that the supports effectively shield the enzyme from thermal inactivation. Overall, these findings underscore the potential utility of PEG-enhanced sonogel and xerogel supports in various industrial enzyme applications, providing valuable insights into their operational, storage, and thermal stability.
