No pertinent human intervention studies were retrieved by the search. The Panel considers that Bi‐07 is sufficiently characterised. Serine is a polar amino acid with a hydroxyl group in its side chain, whereas phenylalanine is nonpolar because of its hydrophobic benzyl side chain. bulgaricus, which have been evaluated with a favourable outcome for their effect on lactose digestion by the Panel (EFSA NDA Panel, 2010). The odds of higher severity classes of abdominal pain and flatulence were significantly increased in the Bi‐07 period compared with lactase (OR 3.13 (95%CI 1.10; 8.87) and 3.4 (1.29; 9.00), respectively, but not compared with placebo (1.02 (0.38; 2.74) and 0.86 (0.34; 2.19), respectively. The Panel considers that increasing lactose digestion is a beneficial physiological effect for individuals with lactose maldigestion provided that the symptoms of lactose maldigestion are improved. The Panel considers that increasing lactose digestion is a beneficial physiological effect for individuals with lactose maldigestion provided that the symptoms of lactose maldigestion are improved. This supports the concept of a partial block in the acetic acid production pathway. lactis Bi‐07, specifications and details of test methods for Bi‐07, certificates of analysis for three batches of Bi‐07, manufacturing process of Bi‐07, stability data of Bi‐07, certificate of analysis present in the clinical study reports of the study by Uebelhack (2019 unpublished) and Donazzolo (2019 unpublished), certificate of analysis of Bi‐07 in the in vitro studies by Forssten (2019 unpublished), Forssten and Marttinen (2019 unpublished) and Rasinkangas (2019 unpublished). lactis CECT 7954 or CECT 7953 was used for the manufacture of fermented milk.

In the statistical analysis, iAUC was analysed on the natural log‐transformed scale. Each of these three questions needs to be assessed by the NDA Panel with a favourable outcome for a claim to be substantiated. Two human intervention studies which investigated a single dose effect of Bi‐07 on lactose digestion using the hydrogen breath test, as well as on gastrointestinal symptoms were submitted. microbiome is TRULY unique, and is determined partly by genetics and partly by the environment. Each person’s. We have chosen strain CECT 7954, a spontaneous extracellular polysaccharide-producing strain that was isolated in our lab from a dairy isolate. However, the Panel also considered that these studies provide no evidence that increasing lactose digestion through the consumption of Bi‐07 (1012 CFU) improves GI symptoms of lactose maldigestion, which is considered a beneficial physiological effect. The scientific substantiation of health claims on improved lactose digestion that were assessed previously was based on human intervention studies showing an effect of the food/constituent on symptoms of lactose maldigestion (subjective outcomes), as well as an increase in lactose digestion (objectively measured by the breath hydrogen concentration method) when consumed with lactose‐containing foods by individuals with symptoms of lactose maldigestion, and also on the biological plausibility of the effect. In both cases, viable counts after fermentation/storage of the fermented milk samples were over 108 CFU/ml (Table 3), higher than the bifidobacterium levels reported in commercial fermented milk samples (104 to 107 CFU/ml). Generally speaking, probiotics are safe, but always check with your doctor before taking any supplements. November 2014, vol 31, issue 8, pp 555–561. are found primarily in the colon and large intestine. Increasing lactose digestion is a beneficial physiological effect for individuals with lactose maldigestion provided that the symptoms of lactose maldigestion are improved. Second, the genus Bifidobacterium is composed mainly of strictly anaerobic members, with some exceptions, which makes their industrial use difficult (12). There is even evidence that it speeds up the colonic transit time in healthy humans[10][11]. All Rights Reserved. Look at the strain diversity — the more diverse the better. Ano ang mga kasabihan sa sa aking kababata? Samples were collected during 6 h of incubation with 30‐min intervals during the first hour and thereafter with 1‐h intervals. B. breve (Bifidobacterium breve) — has been used to fight infections; helps absorb nutrients and fiber B. animalis — found in some yogurt, such as Dannon’s Activia; has immune-boosting properties and helps with digestion the presence of lactose in the colonic lumen) does not necessarily lead to lactose intolerance (‘symptomatic lactose maldigestion’). The proposed target population is ‘persons with lactose maldigestion’. In addition, a carry‐over effect was observed. lactis Bi‐07 and a beneficial physiological effect (i.e. An example is Bifidobacterium animalis subsp. On 27/02/2020, the Working Group on Claims of the NDA Panel agreed on a list of questions for the applicant to provide additional information to accompany the application. lactis DSM10140.   These products are not intended to diagnose, treat, cure, or prevent any disease.

It should also be highlighted that the scope, the proposed wording of the claim and the conditions of use as proposed by the applicant may be subject to changes, pending the outcome of the authorisation procedure foreseen in Article 18(4) of Regulation (EC) No 1924/2006. Pagkakaiba ng pagsulat ng ulat at sulating pananaliksik? lactis BI7, a well-known probiotic strain, has shown the potential to redress inflammation-dependent dysbioses of the enterocyte Abstract Using a previously developed in vitro model to characterize the enterocyte-adherent microbiota fraction, we explored the potential of the probiotic strain Bifidobacterium animalis ssp. As a rule, health claims are prohibited unless they comply with the general and specific requirements of this Regulation, are authorised in accordance with this Regulation, and are included in the lists of authorised claims provided for in Articles 13 and 14 thereof. To determine the genetic changes induced by UV mutagenesis in strain CECT 7953, we sequenced the genomes of both strains. There was a statistically significant sequence effect in the study. Working off-campus? Food/constituent as stated by the applicant. Power calculation was based on a 35% decrease in the incremental area under the curve (iAUC; ppm x h) of breath hydrogen concentrations for Bi‐07 compared with placebo (the expected effect was based on the results of a previously performed study by Sanders et al. Bifidobacteria obtain some ATP equivalents at a substrate level through the glycolytic pathway by coupling acetic acid production from acetyl phosphate (Fig. In the PP population, iAUC for breath hydrogen was statistically significant lower in the Bi‐07 period compared with placebo (mean values ± SD: 172.5 ± 86.33 vs. 219.4 ± 101.21 ppm/hour; geometric LSM ratio 0.462 (95% CI 0.249; 0.859); p = 0.0156). This strain is able to grow in the presence of oxygen in both static and agitated cultures and is thus of interest to industry and a good candidate for the study of potential human health benefits. We focused on the four differential SNPs contained in the CECT 7953 genome, which are listed in Table 1. The health claim application on ‘Bifidobacterium animalis subsp. the improvement of symptoms of lactose maldigestion) in individuals with lactose maldigestion. Differential SNPs in the CECT 7953 genome with respect to strain CECT 7954. Sorry, your blog cannot share posts by email. The reaction was started by the addition of 30 μl ATP (333 mM in 1 M Tris) and stopped after 60 min of incubation at 37°C by transferring 300 μl of the assay mixture into 750 μl of 77 mM FeCl3, in 1 M HCl. 18 April 2018.

Sodium fluoroacetate is incorporated by acetate kinase to the central metabolism of bifidobacteria and irreversibly inhibits aconitate hydratase, an enzyme of the Krebs cycle, as shown in Fig. Thus, the natural presence of acetic acid in milk fermented by strain CECT 7953 might mediate beneficial effects, although this speculative point is reserved for further research. Web. lactis LKM512", Glycoconjugate Journal. Effects of 28-day Bifidobacterium animalis subsp. Stationary-phase cultures of strain CECT 7953 in MRSC elaborated without sodium acetate produced 4.3-fold less acetic acid than wild-type strain CECT 7954 (3.73 ± 0.17 versus 16.10 ± 1.01 mM, respectively) after 24 h of growth.

European Food Safety Authority, Glucose and organic acid levels are presented as the means of at least three independent experiments. 18 April 2018. Both strains were separately propagated (1% wt/vol) in the milk overnight at 37°C and in aerobiosis and used to inoculate freshly prepared milk. Our Customers Reported In comparison, the activity of lactase administered in the studies ranged from 777 to 871 FCC/g. A similar strategy has previously been used to select low acetate producers of Thermoanaerobacter thermohydrosulfuricus (14). Parma, Italy. lactis CECT 7953, obtained by random UV mutagenesis, which produces less acetic acid than the wild type (CECT 7954) in three different experimental settings: De Man-Rogosa-Sharpe broth without sodium acetate, resting cells, and skim milk. One sachet containing either placebo (maltodextrin), 1.8 × 1012 CFU Bi‐07, or 4500 Food Chemicals Codex (FCC) units of lactase with maltodextrin as a carrier, was mixed using a blender by study personnel with 250 mL of water and 25 g lactose (Donazzolo, 2019 unpublished), or with 521 mL of fat‐free milk containing 25 g lactose (Uebelhack, 2019 unpublished) immediately before administration.
