“…On the other hand, deconjugated free bile salt inhibits probiotics. Previous studies have noted that presence of resistant starch promoted survival of Bifidobacteria in the intestinal tract of rats even though, in the presence of bile and low pH (Wang et al, 1999). Although present study showed that bile did not influence bacterial adhesion to rice starch.…”

Resistant starch as prebiotics can be combined with probiotics to increase their survival during processing of food products. In present study Lactic Acid Bacteria (LAB) which, isolated from (yoghurt, banana and human breast milk) were screened for their probiotic properties and evaluated for the adhesion properties to Rice Resistance Starch (RRS). 26% of the isolates (10/39) overcame the stress to pH 3 and 0.3% bile indicating their probiotic properties. All ten LAB isolates adhered to RRS within 60 min of exposure. Isolates Bn1 and HM2 were highly adhered to RRS with a total of 79 and 77% of the cells adhering, respectively. Moderate adherent was observed by isolates FY (55%), YN (70%), CY (48%), HM1 (61, 5%), HM3 (65%) and HM4 (50, 5%), while isolate YD and Bn2 were poorly adhered to RRS (<40% adherent). NaCl and Tween 80 did not influence on adhesion capacity but, the adhesion was inhibited by protease and by low pH. Different effect on adhesion of probiotic bacteria to resistant rice starch was caused by monosaccharides, disaccharides and polysaccharides, depending on their molecular size. The effect of gastric condition (in vitro) appeared, inhibition in adhesion by protease and low (pH<3). While bile has not affected on adhesion , but the pancreatin caused weakening binding capacity of the starch. It might be possible to utilization adhesion of probiotic and prebiotic in microencapsulation and synbiotic food applications such as bakery products.

“…What should also be born in mind is that the combination of probiotic bacteria with other food ingredients present in food products may improve the viability of microorganisms during gastric transit. This is because of the protection exerted by certain food components leading to an enhanced gastric survival (Charteris et al, 1998;Wang et al, 1999;Zárate et al, 2000;Huang and Adams, 2004).…”

ABSTRACT:A bacteriocin-like substance (BLS) producing Enterococcus faecium CE5-1 was isolated from the gastrointestinal tract (GIT) of Thai indigenous chickens. Investigations of its probiotic potential were carried out. The competition between the BLS probiotic strain and antibiotic-resistant enterococci was also studied. Ent. faecium CE5-1 exhibited a good tolerance to pH 3.0 after 2 h and in 7% fresh chicken bile after 6 h, but the viability of Ent. faecium CE5-1 decreased by about 2-3 log CFU/ml after 2 h incubation in pH 2.5. It was susceptible to the antibiotics tested (tetracycline, erythromycin, penicillin G, and vancomycin). The maximum BLS production from Ent. faecium CE5-1 was observed at 15 h of cultivation. It showed activity against Listeria monocytogenes DMST17303, Pediococcus pentosaceus 3CE27, Lactobacillus sakei subsp. sakei JCM1157, and antibiotic-resistant enterococci. The detection by polymerase chain reaction (PCR) in the enterocin structural gene determined the presence of enterocin A gene in Ent. faecium CE5-1 only. Ent. faecium CE5-1 showed the highest inhibitory activity against two antibiotic-resistant Ent. faecalis VanB (from 6.68 to 4.29 log CFU/ml) and Ent. gallinarum VanC (from 6.76 to 4.31 log CFU/ml) after 12 h of co-cultivation. The results show the future possible use of Ent. faecium CE5-1 as a probiotic strain for livestock to control antibiotic-resistant enterococci.

“…A range of human intestinal bacteria can ferment soluble starch; the most numerically dominant of these bacteria are members of the genera Bacteroides, Bifidobacterium, Fusobacterium, and Butyrivibrio (19). However, in animal models, inclusion of resistant starches in the diet has been shown to increase the population of bifidobacteria in the intestinal tract (4,5,16,25,29). Resistant starches have therefore also been proposed as potential prebiotics.…”

Adhesion of 19Bifidobacterium strains to native maize, potato, oat, and barley starch granules was examined to investigate links between adhesion and substrate utilization and to determine if adhesion to starch could be exploited in probiotic food technologies. Starch adhesion was not characteristic of all the bifidobacteria tested. Adherent bacteria bound similarly to the different types of starch, and the binding capacity of the starch (number of bacteria per gram) correlated to the surface area of the granules. Highly adherent strains were able to hydrolyze the granular starches, but not all amylolytic strains were adherent, indicating that starch adhesion is not a prerequisite for efficient substrate utilization for all bifidobacteria. Adhesion was mediated by a cell surface protein(s). For the model organisms tested (Bifidobacterium adolescentis VTT E-001561 and Bifidobacterium pseudolongum ATCC 25526), adhesion appeared to be specific for ␣-1,4-linked glucose sugars, since adhesion was inhibited by maltose, maltodextrin, amylose, and soluble starch but not by trehalose, cellobiose, or lactose. In an in vitro gastric model, adhesion was inhibited both by the action of protease and at pH values of <3. Adhesion was not affected by bile, but the binding capacity of the starch was reduced by exposure to pancreatin. It may be possible to exploit adhesion of probiotic bifidobacteria to starch granules in microencapsulation technology and for synbiotic food applications.
