“…It should be noted that melanoidins also have an antibacterial role [ 82 ], being able to influence the microbiota in this way as well. They inhibit the development of pathogenic species, such as Salmonella typhimurium , Staphylococcus aureus , Escherichia coli , Bacillus cereus and Pseudomonas aeruginosa [ 83 , 108 , 109 , 110 ]. Melanoidins inhibited the ability of Streptococcus mutans to form adherent biofilms [ 107 ].…”

Beer is one of the most consumed drinks worldwide. It contains numerous categories of antioxidants, phenolic products, traces of group B vitamins, minerals (selenium, silicon, potassium), soluble fibers and microorganisms. Low or moderate beer consumption, with or without alcohol, showed positive effects on health by stimulating the development of a healthy microbiota. In the present review we focused on four components responsible with interaction with gut microbiota: microorganisms, polyphenols, fiber and melanoidins, their presence in usual beers and on perspectives of development of fortified beers with enhanced effects on gut microbiota. Though microorganisms rarely escape pasteurization of beer, there are new unpasteurized types that might bring strains with probiotic effects. The polyphenols from beer are active on the gut microbiota stimulating its development, with consequent local anti-inflammatory and antioxidant effects. Their degradation products have prebiotic action and may combat intestinal dysbiosis. Beer contains dietary fiber such as non-starchy, non-digestible carbohydrates (β-glucans, arabinoxylans, mannose, fructose polymers, etc.) that relate with gut microbiota through fermentation, serving as a nutrient substrate. Another type of substances that are often considered close to fiber because they have an extremely low digestibility, melanoidins (melanosaccharides), give beer antioxidant and antibacterial properties. Though there are not many research studies in this area, the conclusion of this review is that beer seems a good candidate for a future functional food and that there are many pathways by which its ingredients can influence in a positive manner the human gut microbiota. Of course, there are many technological hinderances to overcome. However, designing functional beers fortified with fiber, antioxidants and probiotics, with a very low or no alcoholic content, will counteract the negative perception of beer consumption, will nullify the negative effects of alcohol, while simultaneously exerting a positive action on the gut microbiota.

“…In relation to the need for and lack of rapid bacterial diagnostics, the work of Malita M.A. demonstrated how an annual report that monitors antimicrobial resistance trends in health care facilities may provide a profile of empirical therapies useful in diverse emergency situations, such as the transmission of resistant bacteria to the oral cavity of newborn babies [ 12 ]. The final study included in this collection is a paper by Cerini P. et al that compared the trends in antimicrobial resistance in clinical isolates, divided by year and by bacteria spp., of samples obtained from nosocomial and community patients.…”

IntroductionSlightly acidic electrolyzed water (SAEW) is sterilizing agent produced by the electrolysis of hydrochloric acid. Because SAEW has been applied to various foods as the disinfectant, SAEW is expected to be used in the medical field. In this study, we evaluated the bactericidal effect of SAEW on various oral bacteria.MethodologyThe bactericidal activity of SAEW against cariogenic bacteria, periodontopathogenic bacteria, and antibiotic‐resistant bacteria was evaluated.ResultsWe first examined the effect of SAEW on Streptococcus mutans UA159 with different reaction time or the number of bacterial cells. SAEW showed complete bactericidal activity against up to 107 cells within 1 min and even 10 s. Against cariogenic bacteria, periodontopathogenic bacteria, and antibiotic‐resistant bacteria, we evaluated the bactericidal effect of SAEW against 10 S. mutans clinical isolates, three periodontopathogenic bacteria, and 18 cephalosporin‐resistant Gram‐negative bacteria, and we found complete killing against all bacteria. Various dilutions (25%, 50%, and 75%) of SAEW by water still showed complete bactericidal activity, while dilutions by artificial saliva lost the bactericidal activity significantly, with 23.3% bactericidal activity even by 75% SAEW. Storage of SAEW for 7 days at room temperature still showed complete killing activity.ConclusionOur results demonstrated that SAEW has a high antibacterial effect on oral bacteria, indicating the possibility of clinical use in the dental field such as disinfection of dental devices and oral care.
