Staphylococcus aureus is a Gram-positive pathogen which able to form biofilms, exhibiting more pronounced resistance antibiotics and disinfectants. The hurdles posed in eradicating biofilms have driven the search for new compounds fight these structures. Phenolic constitute one of most numerous ubiquitous group plant secondary metabolites with many biological activities. aim present work was study potential antimicrobial antibiofilm properties gallic, caffeic, chlorogenic acids against S. as...
These past years have seen an enormous development of the area natural antioxidants and antimicrobials. Eucalyptus globulus is widely cultivated in subtropical Mediterranean regions intensive short rotation coppice plantations. In Portuguese context, E. third species terms forest area. The stump basal part tree, including near-the-ground stem portion woody roots that remain after felling. purpose this work was to study phytochemical profile evaluate antioxidant antimicrobial properties...
Active packaging is designed to control the development of decay- and disease-causing microorganisms emerging as a promising technology for extending shelf-life, maintaining food safety, reducing waste, minimizing risks foodborne diseases. The goal this work was develop characterize bioactive pullulan-based films, containing rockrose (Cistus ladanifer) essential oil. Among other abundant compounds (camphene, bornyl acetate trans-pinocarveol), α-pinene identified major compound oil (39.25%)....
Abstract The increased resistance of pathogenic bacteria to multiple antimicrobial agents is becoming a significant public health threat. For many there are already limited or no effective antimicrobials available treat the infections caused by them. Acinetobacter baumannii Gram‐negative, biofilm‐forming, nonmotile coccobacillus and major human pathogen causing hospital‐acquired infections, such as ventilator‐associated pneumonia, bacteraemia, meningitis, urinary tract wound infections....
Hydrophobic zein-based functional films incorporating licorice essential oil were successfully developed as new alternative materials for food packaging. The lotus-leaf negative template was obtained using polydimethylsiloxane (PDMS). complex surface patterns of the lotus leaves transferred onto with high fidelity (positive replica), which validates proposed proof-of-concept. prepared by casting method and fully characterized Scanning Electron Microscopy (SEM), Fourier-transform infrared...
The global production of synthetic plastics from petroleum-based raw ingredients exceeds 150 million metric tons. environment is threatened by tons plastic waste, thus endangering wildlife and the public's health. These consequences increased interest in biodegradable polymers as potential substitutes for traditional packaging materials. This study aimed to produce characterize k-carrageenan films incorporating Cymbopogon winterianus essential oil, which citronellal was determined be major...
Propolis is a natural resin produced by honeybees with plenty of pharmacologic properties, including antioxidant activity. Oxidative stress disrupts germ cell development and sperm function, demonstrated harmful effects on male reproduction. Several antioxidants have been shown to reduce oxidative damage increase fertility potential; however, little known about the propolis. This work evaluated role propolis in protecting spermatogonial cells from damage. Propolis’ phytochemical composition...
Abstract Petroleum-based plastics have been widely used as packaging materials because of their low-cost availability and good mechanical properties. However, the use has become restricted they are highly resistant to biodegradation, causing environmental problems. This work aimed produce characterize emulsified pullulan films incorporating geraniol for application food with potential substitute conventional plastics. When was incorporated in films, showed antimicrobial activity against...
Polyphenols and particularly flavonoids are widely appreciated for their potential beneficial health effects, like antioxidant or anticarcinogenic activities. The aim of this study was to determine the activity extracts some shrubs that grow spontaneously in Portugal (Pterospartum tridentatum, Cytisus scoparius and Erica spp.) then correlate it with total phenolic flavonoid compounds. Folin-C method used phenols while a colorimetric aluminum chloride determination flavonoids. Regarding...
In the ecosystem of Serra Da Estrela, some plant species have potential to be used as raw material for extraction bioactive products. The goal this work was determine phenolic, flavonoid, tannin and alkaloid contents methanolic extracts shrubs ( Echinospartum ibericum, Pterospartum tridentatum, Juniperus communis, Ruscus aculeatus, Rubus ulmifolius, Hakea sericea, Cytisus multiflorus, Crataegus monogyna, Erica arborea Ipomoea acuminata), then correlate phenolic compounds flavonoids with...
