Probiotic bacteria in aquaculture represent a control alternative and prevention of pathogens, in addition, reduce the use of antibiotics. However, it is necessary to search for other groups of bacteria with similar or better properties, obtained even from the same source. The aim of the study was to identify molecularly lactic acid bacteria with probiotic properties isolated from the posterior intestine of Nile tilapia (Oreochromis niloticus). The study was carried out from November 2017 to March 2018 evaluating the antagonistic, proteolytic, amylolytic, and antibiotic sensitivity activities, and antagonistic to the following pathogens: Aeromonas hydrophila, Aeromonas veronii, Pseudomonas aeruginosa, Pseudomonas putida and Plesiomonas shigelloides. It was identified by sequencing the 16S rRNA gene that Enterococcus faecium (IP5-2a) and Pedioc...

The probiotics are products based on different microorganism strains, those products have evolved from a just simple mixture of active bacteria to products with specific properties of adherence, colonization, synergies, antibacterial activity, etc. Probiotic products for livestock and aquaculture production are designed with strains developed to operate under specific conditions and which need to be understood and taken into account by the producers because different results can be observed depending of specie(s), geographic area, and type of culture production. The available information suggests that probiotic display a progress from: (a) a better understanding of the bacterial micro-ecosystem and target organs, (b) strain source and their particular characteristics, (c) doses and target species, (d) specific adhesion and/or colonization mechanisms, (e) specific activation of the immune...

Daily consumption of probiotics reduce levels of serum cholesterol by up to 3%, which is significant to prevent hypercholesterolemia, a risk factor for cardiovascular disease and cause of mortality. The genus Lactobacillus is used in industry as a probiotic and some species reduce serum cholesterol by two mechanisms, the adsorption of cholesterol and the production of the enzyme bile salt hydrolase, which vary according to species. The aim of the study was to assess the ability of probiotic bacteria group isolated from coast serum. 53 strains were isolated from nine coastal serum sample; the sensitivity to cefoxitin and vancomycin, and the tolerance to pH 2.0 and 0.3% bile salts were evaluated to determine its probiotic potential. Five microorganisms were selected and molecularly identified as Lactobacillus fermentum. The ability to absorb cholesterol measured by the method of Kimoto, sh...

The present study, had the purpose of developing a fermented non-dairy probiotic drink based on tarwi, for this purpose the legume was unmarked, and then obtained Tarwi Vegetable Extract (EVQ) by blending it, then proceeded to make mixtures with sucrose (6 and 12%) and inoculum of Saccharomyces boulardii (2 and 4%) thus obtaining a total of 4 treatments (A1 - A4), the inoculation was performed at 37 ° C with constant agitation at 20 RPM for a period of 24 hours; where at three-hour intervals readings of the biomass increase were made with a microscope and a neubauer chamber expressed in (cfu / ml) at intervals of 3 hours, curves and kinetic parameters of microbial growth were constructed with the mathematical model of Gompertz, a monitoring of ° Brix, density, pH, and% of acidity was carried out, a linear regression analysis was applied; finally the adjustment of the mathematical model...

This study is part of research developed in the area of Food Science, Department of Analytical Chemistry and Food, University of Vigo Ourense Campus, Spain.; whose ultimate goal is to occurring fermented beverages with probiotic properties with kefir grains juice of red and white grapes would thus not valuing vinificables grapes with low commercial value or direct consumption. And obtaining healthy drinks combining ink effects mainly polyphenol grape character with antioxidant kefir and functional benefits. Kinetics main fermentation process cash studied, the effect of change on the fermentation substrate and microbial populations analyzed kefir. The procedure was carried out as follows: the pellet was activated, conducted a sequence of four successive crops. In each one the juice grain was incubated of nonsterile red grape during 24 h. The grain separated and juice fermented by fr...

The use of the lasctobacilos as probiotics has been increased due to its beneficial properties for the human and animal health. With the objective to identify and to obtain native starais of lactobacilos to be used as probiotics , 9 isolated lactobacilos from different natural sources were selected. The Lactobacillus species were identified by carbohydrate fermentation patterns and by the Polymerase Chain Reaction using specific primers designed from 16S-23S rDNA intergenic spacer regions. The selected lactobacilos belong to the following species: Lactobacillus plantarum, Lb acidophilus, Lb. casei and Lb. fermentum corresponding in number of strains by species 3, 3, 2 and 1 respectively. The probiotic potential of these microorganismos was determined by low pH stability, tolerance to bile and their antimicrobial activity against the enteric pathogens Listeria monocytogenes and Escherichi...

Over the years, people has ben changing their alimentation, lifestyles and ways of thinking. This leads to search a healthy life, careful of what we eat and looking for products that has more benefits and help us with the digestion, for example, probiotic foods or drinks. This study evaluates the market, technical, economic and finantial viability of the installation of production plant for probiotic drinks based on kombucha tea, pineapple and ginger. The main properties of this drink are vitamins, antioxidants and digestive enzymes. The product will be presented en glass bottles of 350 ml, which will be able to maintain the appropiate conditions of the beverage to preserve it. The plant will be located in San Juan de Lurigancho district because of the following factors: closeness to market, proximity to the raw material, landcost, water availability, workforce, transport and energy. The...

En el presente trabajo se evaluó parcialmente las propiedades probióticas de Enterococcus faecium QPa.1, aislada por primera vez de quesos de elaboración artesanal. Para este propósito se realizaron varias pruebas, y se pudo comprobar una gran sensibilidad a la mayoria de los antibióticos ensayados, ausencia de actividad hemolítica, actividad antimicrobiana específica frente a Listeria monocytogenes, tolerancia a diferentes concentraciones de sales biliares (0,3 a 2% de bilis de buey) y resistencia a pH 2 y 3. Asimismo reveló una buena actividad proteolítica y propiedades de adherencia. Enterococcus faecium QPa.1 presenta características propias de un probiótico y tiene una buena actividad inhibitoria solo contra Listeria monocytogenes, bacteria de alto riesgo patológico para la salud humana. Por lo tanto, esta cepa seleccionada puede ser útil como probiótico o como cultivo...
