Proteomic Analysis and Virulence Assessment of Granulicatella adiacens Secretome

In conclusion, we unraveled the secretome of G. adiacens, an oral bacterium well-documented in infective endocarditis, but also recently shown to be involved in oral infections. Importantly, the secretome of G. adiacens comprised of a large number of putative virulence factors. Of particular importance is the finding that the G. adiacens secretome comprised of a number of “moonlighting” proteins, which in other species are shown to enhance bacterial colonization and virulence through their multifunctional roles (Pavkova et al., 2017; Graf et al., 2019). Thus, our results provide a basis for investigating the role of secreted proteins of G. adiacens in oral infections as well as in infective endocarditis.

The objective of this study was to examine the safety and functional properties of Staphylococcus simulans PMRS35 isolated from Budu. This strain possessed good lipase activity and moderate protease activity, tolerated 25% of salt, and did not exhibit decarboxylase activity. In addition, this strain displayed not only negative results towards pathogenic genes, hemolytic activity, and biofilm formation ability but also sensitivity to conventional antibiotics which included chloramphenicol, vancomycin, erythromycin, tetracycline, and gentamycin. Most importantly, the isolate maintained its viability towards simulated gastroi...

This study investigated the stability, survival rate, colony release and pH/sugar content of free and microencapsulated probiotic cells in orange juice. Seven types of herbal-based hydrogels (alginate-Persian Gum (PG)) were mixed with various prebiotic (fructooligosaccharides (FOS), and inulin) concentrations and then were used for microencapsulation of Lactococcus lactis ABRIINW-N19 by extrusion method. All formulations showed high encapsulation efficiency (≥98.4%) and acceptable viability of probiotic cells in simulated digestive conditions (≥61%) compared to free cells. All gel formulations showed high stability o...

This study examined for the first time the effect on malolactic fermentation of an autochthonous Oenococcus oeni PG-16, which was isolated following alcohol fermentation of red-fleshed apple cider. The chemical composition and volatile characteristics of red-fleshed apple ciders produced via simultaneous and sequential inoculation of yeast with either PG-16 or a commercial O. oeni 1 strain were examined. The fermentations were monitored by measuring cell viability and organic acid metabolism. Irrespective of the inoculation mode, malic acid and citric acid were rapidly degraded in the presence of PG-16 during alcoholic fer...

This study aimed to investigate the factors affecting the printability and post-processing capacity of cookie dough in extrusion-based 3D printing by modifying the recipe without the addition of gums or stabilizers. Cookie dough formulations with different types of fat (butter and shortening), flour (wheat, rice, and tapioca), the amount of non-fat milk (32.5 or 65 g/100 g flour), and the sugar level (37.5 or 55 g/100 g flour) were investigated for their printability and post-processing capacity. Rheological properties, microstructure, and printability of printing inks were monitored while the moisture loss and dim...

This study, from the perspective of “whole food”, aimed to investigate the composition of TFE and further explore its possible health-promoting effects on cyclophosphamide-induced mice. It was found that TFE was mainly composed of carbohydrates (34.02 ± 1.42%), phenolic compounds (11.57 ± 0.14%), crude proteins (27.72 ± 3.07%) and saponins (2.81 ± 0.00%). Supplementation of TFE at 200 mg/kg·BW/d regulated intestinal homeostasis by improving the intestinal barrier, alleviating dysbacteriosis (reverse 44 of 68 disordered genera), stim...

This study aimed to evaluate: (i) the effectiveness of plasma activated water (PAW) on the germination capacity of mung bean seeds and (ii) the antimicrobial capacity of PAW. A specially designed set-up composed of two electrochemical cell was used to produce two different types of PAW, by surface plasma discharge ignited from copper cathode and copper anode, respectively. The germination capacity of mung bean seeds was assessed over 96 h incubation in the dark at 25 °C. The antimicrobial capacity of PAW was assessed against 6 h exposure to Escherichia coli NCTC 12900. The anodic PAW (rich in NO3−) indicate...
