Dietary changes have accompanied the evolution of humanity and is proven to be fundamental in human well-being. Nutrition essential for survival as a matter health equilibrium body. About 1/3 diet composed by fermented foods beverages, which are widely distributed consumed different societies around world, no culture lifestyle. Fermented derived from fermentation process substrates microorganisms, more importantly humans, those with beneficial characteristics, due positive impact on health....
The present work aimed to characterize the impact of an anthocyanin-rich blueberry extract upon growth, adhesion and biofilm formation several pathogens including some multiresistant bacteria.A group comprised reference strains clinical isolates Pseudomonas aeruginosa, Escherichia coli, Proteus mirabilis, Acinetobacter baumannii Staphylococcus aureus, were used screen for antimicrobial activity. Microbial growth was determined through measurement optical density while using standard crystal...
Oral candidiasis is particularly evident, not only in cancer patients receiving chemotherapy, but also elderly people with xerostomy. In general, Candida an opportunistic pathogen, causing infections immunocompromised and, some cases, when the natural microbiota altered. Chitosan, a derivative of chitin, polysaccharide that has been proven to possess broad spectrum antimicrobial activity encompasses action against fungi, yeast and bacteria. While recent studies have revealed significant...
Carboxymethyl cellulose use in industry is ubiquitous. Though it recognized as safe by the EFSA and FDA, newer works have raised concerns related to its safety, vivo studies showed evidence of gut dysbiosis associated with CMC’s presence. Herein lies question, CMC a pro-inflammatory compound? As no work addressed this we sought understand whether was through immunomodulation GI tract epithelial cells. The results that while not cytotoxic up 25 mg/mL towards Caco-2, HT29-MTX Hep G2 cells, had...
Chitosan is a natural compound that has been validated as viable antimicrobial agent against Staphylococcus aureus. With this work we sought to evaluate the planktonic and sessile sensitivity of methicillin-resistant S. aureus chitosan's activity if (MRSA) would be more or less sensitive than methicillin-sensitive (MSSA).A group comprised reference strains clinical multiresistant isolates MSSA MRSA were used. Methicilin resistance effect upon chitosan was assessed in setting different phases...
Microorganisms can colonize a wide variety of medical devices, putting patients in risk for local and systemic infectious complications, including local-site infections, catheter-related bloodstream endocarditis. These microorganisms are able to grow adhered almost every surface, forming architecturally complex communities termed biofilms. The use natural products has been extremely successful the discovery new medicine, mushrooms could be source antimicrobials. present study reports...
Abstract BACKGROUND The olive oil industry generates significant amounts of semi‐solid wastes, namely pomace. Olive pomace is a by‐product rich in high‐value compounds (e.g. dietary fibre, unsaturated fatty acids, polyphenols) widely explored to obtain new food ingredients. However, conventional extraction methods frequently use organic solvents, while novel eco‐friendly techniques have high operational costs. development powdered products without any step has been proposed as more feasible...
Carboxymethyl cellulose is the most used water-soluble with applications in industries such as food, cosmetics, and tissue engineering. However, due to a perceived lack of biological activity, carboxymethyl mostly structural element. As such, this work sought investigate whether CMC possesses relevant properties that could grant it added value cosmeceutical ingredient future skincare formulations. To end, samples (Mw between 471 322 kDa) skin cell cytotoxicity, impact upon pro-collagen I α...
In recent years, pomegranate oil has obtained more attention due to its content of conjugated linolenic acids and possible application in the prevention many diseases. The purpose this work was evaluate potential ability modulate obesity-related metabolism immune response using vitro models. regard, characterized terms fatty profile, tocopherols phytosterols, antioxidant capacity. After evaluation safety oil’s capacity evaluated through adipolysis adipokines secretion quantification 3T3-L1...
Spent yeast waste streams are a byproduct obtained from fermentation process and have been shown to be rich secondary source of bioactive compounds such as phenolic peptides. The latter particular interest for skin care cosmetics they safe hypoallergenic while simultaneously being able exert various effects upon the epidermis modulating immune response targeting metabolites, collagen production. As potential spent yeast's peptides has mainly explored food-related applications, this work...
Sugarcane bagasse (SCB) is the main residue of sugarcane industry and a promising renewable sustainable lignocellulosic material. The cellulose component SCB, present at 40–50%, can be used to produce value-added products for various applications. Herein, we comprehensive comparative study green traditional approaches extraction from by-product SCB. Green methods (deep eutectic solvents, organosolv, hydrothermal processing) were compared (acid alkaline hydrolyses). impact treatments was...
