AbstractKombucha is a beverage made by fermenting sugared tea using a symbiotic culture of bacteria belonging to the genus Acetobacter, Gluconobacter, and the yeasts of the genus Saccharomyces along with glucuronic acid, which has health-promoting properties. The paper presents the evaluation of ferments as a potential cosmetic raw material obtained from Yerba Mate after different fermentation times with the addition of Kombucha. Fermented and unfermented extracts were compared in terms of chemical composition and biological activity. The antioxidant potential of obtained ferments was analyzed by evaluating the scavenging of external and intracellular free radicals. Cytotoxicity was determined on keratinocyte and fibroblast cell lines, resulting in significant increase in cell viability for the ferments. The ferments, especially after 14 and 21 days of fermentation showed strong ability to inhibit (about 40% for F21) the activity of lipoxygenase, collagenase and elastase enzymes and long‐lasting hydration after their application on the skin. Moreover, active chemical compounds, including phenolic acids, xanthines and flavonoids were identified by HPLC/ESI–MS. The results showed that both the analyzed Yerba Mate extract and the ferments obtained with Kombucha may be valuable ingredients in cosmetic products.

Abstract Kombucha is a beverage made by fermenting sugared tea using a symbiotic culture of bacteria belonging to the genus Acetobacter, Gluconobacter, and the yeasts of the genus Saccharomyces along with glucuronic acid, contribute to health protection. The paper presents the evaluation of ferments as a potential cosmetic raw material obtained from Yerba Mate after different fermentation times with the addition of kombucha. Fermented and unfermented extracts were compared in terms of chemical composition and biological activity. Studies of antioxidant properties were carried out using DPPH and ABTS radicals. A significant decrease in the intracellular level of free radicals was also observed. Cytotoxicity was determined on keratinocyte and fibroblast cell lines, resulting in significant increase in cell viability for the ferments. In addition, the ferments showed strong ability to inhibit the activity of lipoxygenase and collagenase and elastase enzymes and long‐lasting hydration after their application on the skin. Extract obtained after 21 days of fermentation contained the highest amount of phenolic acids and xanthines. The results showed that both the analyzed Yerba Mate extract and the ferments obtained with kombucha may be valuable ingredients in cosmetic products.

<p>This research aims to get both the active chemical compounds of <em>galam’s</em>wood vinegar which functions as antifungi and anti-termite usage and the process or factors influence it. Another purpose of the research is to find how effective the active compounds are toward wood destroyer organisms, either termite or fungus. Anti-termite assay is done by using a method of the mortal percentage of termites in sort of <em>Cryptotermes cynocephalus</em> Light and a method of growth inhibition of <em>Schizopyllum commune</em> fungus by wood vinegar for antifungi assay. To find the influence within the treatment of wood vinegar production process (the raw material condition and distillation), wood vinegar concentration level concerning with the active compounds of antifungi and anti-termite, each of treatments is analyzed using statistical analysis with CRD. Wood vinegar is a natural organic liquid resulting from the condensation of smoke in the process of making charcoal. Generally, the result shows that galam’s wood vinegar have a potential used as natural wood preservative material. For this kind of utility, the vinegar can either be spontaneously used or be reproduced by a distillation process with 50% concentration. Galam’swood vinegar contains some components, namely phenolic, acid and carbonyl.</p>

Abstract Background Lactic acid bacteria can synthesize dextran and oligosaccharides with different functionality, depending on the strain and fermentation conditions. As natural structure-forming agent, dextran has proven useful as food additive, improving the properties of several raw materials with poor technological quality, such as cereal by-products, fiber-and protein-rich matrices, enabling their use in food applications. In this study, we assessed dextran biosynthesis in situ during fermentation of brewers´ spent grain (BSG), the main by-product of beer brewing industry, with Leuconostoc pseudomesenteroides DSM20193 and Weissella confusa A16. The starters performance and the primary metabolites formed during 24 h of fermentation with and without 4% sucrose (w/w) were followed. Results The starters showed similar growth and acidification kinetics, but different sugar utilization, especially in presence of sucrose. Viscosity increase in fermented BSG containing sucrose occurred first after 10 h, and it kept increasing until 24 h concomitantly with dextran formation. Dextran content after 24 h was approximately 1% on the total weight of the BSG. Oligosaccharides with different degree of polymerization were formed together with dextran from 10 to 24 h. Three dextransucrase genes were identified in L. pseudomesenteroides DSM20193, one of which was significantly upregulated and remained active throughout the fermentation time. One dextransucrase gene was identified in W. confusa A16 also showing a typical induction profile, with highest upregulation at 10 h. Conclusions Selected lactic acid bacteria starters produced significant amount of dextran in brewers’ spent grain while forming oligosaccharides with different degree of polymerization. Putative dextransucrase genes identified in the starters showed a typical induction profile. Formation of dextran and oligosaccharides in BSG during lactic acid bacteria fermentation can be tailored to achieve specific technological properties of this raw material, contributing to its reintegration into the food chain.

The present study aimed to evaluate the effect of Jerusalem artichoke processing methods and drying methods (freeze drying, sublimation drying, vacuum drying) on the basic physicochemical parameters, profiles and contents of sugars and polyphenolic compounds, and health-promoting properties (antioxidant activity, inhibition of the activities of α-amylase, α-glucosidase, and pancreatic lipase) of the produced purée. A total of 25 polyphenolic compounds belonging to hydroxycinnamic phenolic acids (LC-PDA-MS-QTof) were detected in Jerusalem artichoke purée. Their average content in the raw material was at 820 mg/100 g dm (UPLC-PDA-FL) and was 2.7 times higher than in the cooked material. The chemical composition and the health-promoting value of the purées were affected by the drying method, with the most beneficial values of the evaluated parameters obtained upon freeze drying. Vacuum drying could offer an alternative to freeze drying, as both methods ensured relatively comparable values of the assessed parameters.

BACKGROUND: With essential metals being studied and developed as anticancer agents, this study aims to explore the anticancer activity of Zn(II) arginine dithiocarbamate in the T47D and fibroblast cell lines. METHOD: The Zn(II) arginine dithiocarbamate complex was prepared by the in situ method and characterized using infra-red spectroscopy, melting point, X-ray fluorescence, and X-ray diffraction instruments. The complex compound was tested for its cytotoxicity to the T47D breast cancer and fibroblast cell lines. RESULTS: The cytotoxicity of the Zn(II) arginine dithiocarbamate complex to the T47D breast cancer cell line obtained IC50 = 3.16 μg/mL, while cisplatin obtained IC50 = 28.18 μg/mL. The cytotoxicity of the Zn(II) arginine dithiocarbamate complex to fibroblast cells obtained IC50 = 8709.63 μg/mL. CONCLUSION: The Zn(II) arginine dithiocarbamate complex has increased active cytotoxicity compared to cisplatin in inducing morphological changes in the T47D breast cancer cell line and is relatively non-toxic to fibroblast cells.

This study proposes a review on hyaluronic acid (HA) known as hyaluronan or hyaluronate and its derivates and their application in cosmetic formulations. HA is a glycosaminoglycan constituted from two disaccharides (N-acetylglucosamine and D-glucuronic acid), isolated initially from the vitreous humour of the eye, and subsequently discovered in different tissues or fluids (especially in the articular cartilage and the synovial fluid). It is ubiquitous in vertebrates, including humans, and it is involved in diverse biological processes, such as cell differentiation, embryological development, inflammation, wound healing, etc. HA has many qualities that recommend it over other substances used in skin regeneration, with moisturizing and anti-ageing effects. HA molecular weight influences its penetration into the skin and its biological activity. Considering that, nowadays, hyaluronic acid has a wide use and a multitude of applications (in ophthalmology, arthrology, pneumology, rhinology, aesthetic medicine, oncology, nutrition, and cosmetics), the present study describes the main aspects related to its use in cosmetology. The biological effect of HA on the skin level and its potential adverse effects are discussed. Some available cosmetic products containing HA have been identified from the brand portfolio of most known manufacturers and their composition was evaluated. Further, additional biological effects due to the other active ingredients (plant extracts, vitamins, amino acids, peptides, proteins, saccharides, probiotics, etc.) are presented, as well as a description of their possible toxic effects.
