Infrared absorption spectroscopy is a powerful analytical tool that enables the identification of molecular species. The sensitivity this technique, strongly limited by small cross-section vibration, can be greatly improved resonant interaction with nano-antennas via surface-enhanced infrared (SEIRA) mechanism. However, most examples SEIRA concern solid-state layers adsorbed on nano-antennas, w...

As electrochemical measuring instruments, screen-printed electrodes (SPEs) are constructed via a technology called thick film deposition onto plastic or ceramic substrates, allowing for simple, inexpensive, and rapid on-site analysis with high reproducibility, sensitivity, accuracy. Numerous substances such as gold, silver, platinum, carbon applied electrode construction, enabling the analyst t...

The cork oak tree (Quercus suber L.) symbolizes the Montado landscape in Portugal and is a central element country’s social economic history. In recent decades, loss of thousands oaks has been reported, revealing ongoing decline these agroforestry ecosystems. This emblematic Mediterranean Basin host to soil-born root pathogen Phytophthora cinnamomi, an active driver. this framework, early diagn...

Over four billion tons of foods are produced annually on the planet, and about a third is wasted. A minimal part this waste incinerated or sent to landfills for treatment, avoiding contamination diseases; rest disposed elsewhere. The current review was aimed at broadening panorama potential agroindustrial by-products in applications such as biofuels, biomaterials, biocompounds, pharmaceuticals,...

The world will face a significant protein demand in the next few decades, and due to environmental concerns linked animal protein, new sustainable sources must be found. In this regard, microalgae stand as an outstanding high-quality source. However, different steps are needed separate proteins from biomass other biocompounds. recovery disrupted is usually bottleneck of process, it typically em...

The high costs and environmental concerns associated with using marine resources as sources of oils rich in polyunsaturated fatty acids have prompted searches for alternative sources of such oils. Some microorganisms, among them members of the genus Aurantiochytrium, can synthesize large amounts of these biocompounds. However, various parameters that affect the polyunsaturated fatty acids produ...

BACKGROUND Fatty acids are substantial components of lipids and cell membranes in the form of phospholipids. This review consists of two parts. The present part aims at describing fatty acid classification, dietary sources and biological functions. The second part will focus on fatty acid physiological roles and applications in human health and disease. RESULTS In humans, not all fatty acids ...

Spirulina is produced from pure cultures of the photosynthetic prokaryotic cyanobacteria Arthrospira. For many years research centers throughout the world have studied its application in various scientific fields, especially in foods and medicine. The biomass produced from Spirulina cultivation contains a variety of biocompounds, including biopeptides, biopolymers, carbohydrates, essential fatt...

Physicochemical properties, consumer acceptance, antioxidant and angiotensin-converting enzyme (ACE) inhibitory activities of infusions and fermented beverages of Eucalyptus camaldulensis and Litsea glaucescens were compared. Among physicochemical parameters, only the pH of fermented beverages decreased compared with the unfermented infusions. No relevant changes were reported in consumer prefe...
