Fourier transform infrared (FT-IR) and Raman spectroscopy mapping were applied to the analysis of biofilms produced by bacteria genus Streptococcus. Bacterial biofilm, also called dental plaque, is main cause periodontal disease tooth decay. It consists a complex microbial community embedded in an extracellular matrix composed highly hydrated polymeric substances combination salivary bacterial proteins, lipids, polysaccharides, nucleic acids, inorganic ions. This study confirms value FT-IR...
Due to a widespread occurrence of multidrug-resistant pathogenic strains bacteria, there is an urgent need look for antimicrobial substances, and honey with its properties very promising substance. In this study, we examined the first time novel varietal honeys, i.e., plum, rapeseed, Lime, Phacelia, honeydew, sunflower, willow, multifloral-P (Prunus spinosa L.), multifloral-AP (Acer negundo L., Prunus multifloral-Sa (Salix sp.), multifloral-Br (Brassica napus L.). Their activity was tested...
The aerial parts of selected Potentilla species (P. anserina, P. argentea, erecta, fruticosa, grandiflora, nepalensis, norvegica, pensylvanica, crantzii and thuringiaca) were investigated in order to determine their contents polyphenolic compounds. results showed that fruticosa has relatively high concentrations tannins (167.3 ± 2.0 mg/g dw), proanthocyanidins (4.6 0.2 dw) phenolic acids (16.4 0.8 as well flavonoids (7.0 1.1 calculated quercetin. Furthermore, we the vitro inhibitory effects...
Biofilm-related infections of the oral cavity, including dental caries and periodontitis, represent most prevalent health problems. For years, treatment thereof was largely based on antibacterial chemical agents. Recently, however, there has been growing interest in application more preventive minimally invasive biotechnological methods. This review focuses potential applications enzymes prevention diseases. Dental plaque is a microbial community that develops tooth surface, embedded matrix...
Introduction For centuries, various species from the genus Alchemilla have been utilized in traditional medicine worldwide. Among them, vulgaris L. (Rosaceae) stands out as a promising herbal drug candidate due to its phytochemicals displaying anti-inflammatory and antioxidant properties. Methods In our study, we investigated interaction between human gut microbiota lady’s mantle herb extract (AV) following biotransformation of extract’s constituents their impact on colorectal cancer cells...
The aim of this study was to compare the effect increasing concentrations (0, 1, 2, 4%) sea buckthorn oil (SBO) on structural, physicochemical, release, and antioxidant properties glycerol-plasticized sodium casein (NaCAS) gelatin (GEL) films. Ultrasonic treatment ensured effective homogenization SBO in both types emulsions, resulting yellow-tinted semi-opaque films with relatively low micro-roughness. Generally, GEL demonstrated lower UV barrier solubility but exhibited higher compactness,...
Unlike many biopolymers, α-1,3-glucan (α-1,3-GLU) is water-insoluble, making it a promising candidate for the production of moisture-resistant films with applications in biodegradable packaging, biomedicine, and cosmetics. This study aimed to characterize structural, physicochemical (water affinity, optical, mechanical), biodegradation properties film made from α-1,3-GLU extracted Laetiporus sulphureus. The was fabricated through alkaline dissolution, casting, drying, washing remove residual...
(1→3)-α-d-Glucan is an important component of the cell wall most fungi. The polymer has many applications, including as a therapeutic agent in prevention or treatment various diseases, well heavy metal sorbent and new materials used plastics industry. presence (1→3)-α-d-glucan (water-insoluble, alkali-soluble polysaccharide) Pleurotus djamor (pink oyster mushroom) was confirmed using specific fluorophore-labeled antibodies. Therefore, water-insoluble fraction (WI-ASF) P. B123 fruiting bodies...
To show biological activity of carboxymethylated α-(1 → 3)-d-glucans isolated from the selected macromycetes fungi on human tumor and normal cells. Water-insoluble, alkali-soluble polysaccharides (WIP) were fruiting bodies four fungi: Lentinus edodes, Pleurotus ostreatus, Piptoporus betulinus Laetiporus sulphureus. The structure was determined using composition analysis, methylation fourier transform infrared spectroscopy, nuclear magnetic resonance spectroscopy. chemical spectroscopic...
Of the three cariogenic streptococci grown in four various culture media, strain Streptococcus mutans 20381 was found to produce large amounts of extracellular glucosyltransferase and water-insoluble, adhesive exopolysaccharide when batch on brain-heart infusion broth. Methylation nuclear magnetic resonance analyses revealed that insoluble polymers synthesized by crude preparations were mixed-linkage (1 → 3), 6)-α-D-glucans (so-called mutans) with a greater proportion 1,3 1,6 linkages major...
The mechanisms of action the complex including entomopathogenic nematodes genera Steinernema and Heterorhabditis their mutualistic partners, i.e., bacteria Xenorhabdus Photorhabdus, have been well explained, commercialized as biological control agents against many soil insect pests. However, little is known regarding nature relationships between these gut microbiota infected insects. In present study, 900 bacterial isolates that were obtained from midgut samples Melolontha melolontha larvae...
Cardiovascular diseases remain the leading global cause of mortality indicating need to identify all possible factors reducing primary and secondary risk. This study screened in vitro antiplatelet anticoagulant activities hot water extracts eight edible mushroom species (Agaricus bisporus, Auricularia auricularia-judae, Coprinus comatus, Ganoderma lucidum, Hericium erinaceus, Lentinula edodes, Pleurotus eryngii, ostreatus) increasingly cultivated for human consumption, compared them those...
Alpha-1,3-glucan, in addition to β-1,3-glucan, is an important polysaccharide component of fungal cell walls. It reported for many species, including human pathogenic genera: Aspergillus, Blastomyces, Coccidioides, Cryptococcus, Histoplasma and Pneumocystis, plant pathogens, e.g. Magnaporthe oryzae entomopathogens, Metarhizium acridum. In fungi, α-1,3-glucan considered as a shield the β-1,3-glucan layer preventing recognition pathogen by host. However, its role induction immune response not...
Laetiporus sulphureus is an edible wood-rotting basidiomycete fungus whose fruiting bodies contain substances with verified therapeutic evidences and large amounts of α-(1 → 3)-glucan which used as effective inducer microbial 3)-glucanases. However, production mature this species under artificially controlled conditions has not been reported until now. Here, we provide the first report successful initiation development L. in large-scale experiments. Twelve strains were isolated from a...
