A better understanding of the functionality of probiotics and dietary fibres with prebiotic activity is required for the development of improved synbiotic preparations. In this study, utilization of β(2-1) fructans, galactooligosaccharides, and plant polysaccharides as prebiotics by lactobacilli, bifidobacteria, and pediococci was investigated. Our results demonstrate that prebiotics with linear chains consisting of galactose units are better utilized by probiotics than are those consisting of glucose and fructose units, and the ability of probiotic bacteria to utilize prebiotics is strain-specific. In addition, rye fructooligosaccharides represent a prebiotic fibre that supports the growth of a wide range of probiotic cultures and as such has a potential to improve the successfulness of probiotic treatments. This study also demonstrates dietary fibre utilization by pediococci and provides data supporting the possible use of pediococci as a probiotic in synbiotic combinations.

    • "In order to achieve a better understanding of the functional activity of prebiotics over probiotic bacteria, it is necessary to develop better symbiotic preparations. The success in the establishment of the necessary symbiotic condition is closely related to the compatibility between the chosen components, that is to say, between the prebiotic ingredients and the probiotic bacteria (Mei et al., 2011; Pranckute et al., 2014, Muñoz et al., 2012). The authors suggest that strains of Lactobacillus sp. and Lactococcus sp. may be useful as probiotic bacteria when used together with prebiotics (palatinose, inulin and α-cyclodextrin) so as to create a symbiotic development, which could control not only the grown of beneficial bacteria in the gastrointestinal tract, but also their antibacterial activity.

    ABSTRACT: Prebiotic ingredients are increasingly added to food preparations containing probiotics in order to enhance probiotic survival and growth. Bacteriocins produced by Lactococcus lactis (nisin) have great advantages as a food additive, such as heat stability, nontoxicity and sensitivity to digestive proteases. In this context, the aim of this study was to evaluate the influence of prebiotic ingredients on the fermentation kinetics and antimicrobial activity by Lactococcus lactis subsp. lactis CECT 4434 against Lactobacillus sakei. Lc. lactis was cultivated in MRS medium (Man, Rogosa and Sharpe) supplemented with or without (control) fructooligosacharides (MRS+FOS), polydextrose (MRS+PD) and inulin (MRS+IN). All cultivations were carried out in shaken flasks at 30 °C with agitation speed of 100 rpm. Samples were collected for analyses (biomass, specific growth rate, generation time and antimicrobial activity) every two hours during the 48 h of cultivation. The exponential growth phase of Lc. lactis subsp. lactis CECT 4434 occurred at intervals of 2-8 h for all runs (MRS, MRS+FOS, MRS+PD e MRS+IN). The use of all prebiotic ingredients increased cell biomass, specific growth rate and consequently decreased generation time when compared with control (only MRS). Antimicrobial activity of nisin produced by Lc. lactis subsp. lactis CECT 4434 was detected against Lactobacillus sakei strain.

    ABSTRACT: Abstract Prebiotics are ingredients selectively fermented by the intestinal microbiota that promote changes in its structure and/or metabolism, conferring health benefits to the host. Studies show that +¦ (1-4) galacto-oligosaccharides [+¦ (1-4) GOS], lactulose and fructo-oligosaccharides increase intestinal concentration of lactate and short chain fatty acids, and stool frequency and weight, and they decrease fecal concentration of secondary bile acids, fecal pH, and nitroreductase and +¦-glucuronidase activities suggesting a clear role in colorectal cancer (CRC) prevention. This review summarizes research on prebiotics bioassimilation, specifically +¦ (1-4) GOS, and their potential role in CRC. We also evaluate research that shows that the impact of prebiotics on host physiology can be direct or through modulation of the gut intestinal microbiome, specifically the probiome (autochtonous beneficial bacteria). We present studies on a potential role in CRC progression to finally describe the current state of +¦ (1-4) GOS generation for industrial production

    ABSTRACT: Purpose of review: Due to its scale and its important role in maintaining health, the gut microbiota can be considered as a 'new organ' inside the human body. Many complex carbohydrates are degraded and fermented by the human gut microbiota in the large intestine to both yield basic energy salvage and impact gut health through produced metabolites. Recent findings: This review will focus on the gut microbes and microbial mechanisms responsible for polysaccharides degradation and fermentation in the large intestine. Gut microbes and bacterial metabolites impact the host at many levels, including modulation of inflammation, and glucose and lipid metabolisms. Summary: A complex relationship occurs in the intestine between the human gut microbiota, diet and the host. Research on carbohydrates and gut microbiota composition and functionality is fast developing and will open opportunities for prevention and treatment of obesity, diabetes and other related metabolic disorders through manipulation of the gut ecosystem.
