Seaweeds are a sustainable source of novel functional ingredients with applicability in pharmaceutics, biotechnology, and food science. The bioactivity of most of these marine compounds has scarcely been studied. The present study overviews the bioactivity of the polysaccharide fucoidan derived from Fucus vesiculosus brown algae as an antimicrobial agent against Listeria monocytogenes and Salmonella enterica serovar Typhimurium. The results obtained in vitro in reference medium reveal a bacteriostatic and bactericidal effect of fucoidan against both pathogens, this bioactivity being significantly dependent (p-value ≤ 0.05) on the concentration, 5–1000 μg/mL, temperature, 8–37 °C, and exposure time, 0–12 days. The results were validated in the formulation of a new functional pasteurized apple beverage to be commercialized under refrigeration. Fucoidan added at 25–100 μg/mL was highly effective against both pathogens. These results increase knowledge for the future formulation of new functional beverages that include marine compounds (high content in fibre, high content in protein; prebiotic and antioxidant properties), additionally revealing antimicrobial potential.

This paper investigates the performance, combustion and emission characteristics of a direct injection (DI) diesel engine, fueled with alumina ($$\hbox {Al}_{2} \hbox {O} _{3})$$ Al2O3) nanoparticles-dispersed aloe vera diesel blends. The test fuels B10 (90% diesel and 10% aloe vera biodiesel), $$\hbox {B10}+ \hbox {Al}_{2} \hbox {O}_{3}$$ B10+Al2O3 (90% diesel, 10% aloe vera biodiesel and 30 ppm of $$\hbox {Al}_{2} \hbox {O}_{3}$$ Al2O3 nanoparticles), B20 (80% diesel and 20% aloe vera biodiesel) and $$\hbox {B20}+ \hbox {Al}_{2} \hbox {O}_{3}$$ B20+Al2O3 (80% diesel, 20% aloe vera biodiesel and 30 ppm of $$\hbox {Al}_{2} \hbox {O}_{3}$$ Al2O3 nanoparticles) are prepared separately for each aloe vera diesel blends at a dosage of 30 ppm with an aid of an ultrasonicator. The combustion characteristics such as heat release rate and cylinder pressure are investigated using the data acquisition system, while the engine performance features are examined by brake-specific fuel consumption and brake thermal efficiency. The levels of engine pollutants are analyzed by unburned hydrocarbon (UBHC), carbon monoxide (CO), nitric oxide (NO) and smoke opacity. These investigations disclosed the use of biodiesel blends with $$\hbox {Al}_{2} \hbox {O}_{3}$$ Al2O3 nanoparticles in DI diesel engine with significant amelioration of combustion characteristic and substantial decrement of CO, NO, smoke, UBHC emissions and brake thermal efficiency by 44%, 47%, 37%, 29% and 3%, when compared with the diesel fuel.

Fucoidan is a series of sulfated polysaccharides derived from brown algae, and have reported to have various biological activities. Previously, we demonstrated that fucoidan derived from Cladosiphon okamuranus and Undaria pinnatifida effectively augmented anti-tumor immunity in combination with Agaricus blazei mycelia extract. In this study, we evaluated the capacity of the fucoidan-agaricus mix (FAM) to enhance oral mucosal immune function. Fifteen healthy volunteers (mean age, 41.2 years old; range, 22–56 years old; 8 males, 7 females) ingested 4 capsules each containing 250 mg FAM powder every day for 12 weeks. As a result, the mean of secretory rates of salivary secretory immunoglobulin A (sIgA) tended to be increased by the FAM administration for 4 and 12 weeks as compared with the initial value. The enhanced salivary sIgA secretion was more distinctly observed in subject group whose initial values of salivary sIgA secretory rate were lower than the total average. Furthermore, the intake of FAM led to significant augmentation in the salivary sIgA secretion (by 1.3-fold) in the group of subjects under 40 years of age. On the other hand, concanavalin A-induced blastogenic response of peripheral blood mononuclear cells and serum IgA concentration was not elevated during this trial. Therefore, it was suggested that FAM stimulated functional maturation rather than expansion of B lymphocyte. The intake of FAM did not significantly affect NK cell activities. In addition, the safety of FAM consumption was confirmed because no abnormal findings were observed in general clinical tests. From the results, it was suggested that intake of FAM was useful in augmentation of oral mucosal immune defense via enhancing salivary sIgA production.

Objective: Based on anti-inflammatory effects of Aloe vera, the effect of aqueous extract of this plant on brain edema and changes in some pro-inflammatory cytokines was investigated after traumatic brain injury (TBI). Materials and Methods: In this study, adult male Wistar rats were divided into 5 groups: Sham, TBI, vehicle (Veh), and low dose (LA) and high dose (HA) Aloe vera. The vehicle and aqueous extract of Aloe vera were injected intraperitoneally 30 min after induction of diffuse TBI by Marmarou’s method. Brain edema (brain water content), and transforming growth factor beta (TGF-β), tumor necrosis factor alpha (TNFα), interleukin 6 (IL-6) and IL-1β levels in serum and brain were measured 24 hr after TBI induction. Results: Increased brain edema by TBI was reduced by both LA and HA (p

Abstract Background Aloe vera is a plant that has been used as an alternative drug. This plant contains various compounds, like anthraquinone, saponin, flavonoid, alkaloid, and tannin that has an antibacterial effect against Staphylococcus aureus and Escherichia coli. Both of it were responsible for the infection incident. This study aims to determine the efficacy of Aloe vera sap as an antibacterial against Staphylococcus aureus and Escherichia coli. Methods An experimental study, in vitro using post-test only control group design, has been done at laboratory of Medical Faculty of Sriwijaya University, by examining the antibacterial activity of Aloe vera sap in five different concentration (5%, 10%, 20%, 40%, dan 80%) using well diffusion and solid dillusion method to determine the minimum bactericidal concentration (MBC). And then continued with the phytocemical screening to determine the compound inside the Aloe vera sap. Results Aloe vera sap were able to kill Staphylococcus aureus at 5% and Eshcerichia coli at 80%. Compatibility test showed that Aloe vera sap with concentration of 10%, 20%, 40%, and 80% are compatible with amoxicillin, therefore 80% is compatible with cefotaxime. This ability due to the compound that it contains, which is alkaloid, flavonoid, tannin, quinone, and saponin. Conclusion Aloe vera sap is effective as an antibacterial against Staphylococcus aureus and Escherichia coli.   Keyword: Aloe vera sap, antibacterial, efficacy, Staphylococcus aureus, Escherichia coli.
