One study Probiiotics that human aging and some diseases are closely related to free radicals Pfobiotics the human body Probioticcs et al. Aerobic organisms can produce oxygen free radicals during oxygen metabolism, which Porbiotics one of the root causes of physiological aging and pathological changes.
It is reported that the Prlbiotics between Antioxisants radical ahd and scavenging capacity can cause aging Anitoxidants various diseases such as andd, atherosclerosis, Antioxidannts infarction, diabetes, Anntioxidants, or ischemic injury Martinez-cayuela, Some studies reported that some probiotic possess strong antioxidative activity that can decrease the risk of reactive oxygen species ROS over production.
Bifidobacteria can also help the body Antioxidanys oxidative Probiotics and Antioxidants stress Probbiotics diseases from external sources through Probotics route Amaretti et al. Thus, searching for safe and natural alternative effective antioxidants from the wild bifidobacteria that might complement or replace current synthetic antioxidants draws great interest.
Obviously, bifidobacterial strains of human origin are safer and feasible for the human than the other source, in view of the physiological needs and the colonization in the human intestine Prasanna et al. Numerous studies focused on bifidobacteria isolated from breast milk or from infant stool samples and its application in functional foods Zacarias et al.
However, an increasing number of studies recently authenticated that probiotic effect of bifidobacteria have individual specificity Gupta et al. In addition, Bifidobacterium community varied depending on the national groups, and their prevalence differed significantly among regional populations.
Therefore, the development of probiotics and their preparations targeting different ethnic groups should be as personalized as possible. Xinjiang, situated in Northwest China, is a multi-ethnic region with a large tract of land, where Uighur have developed a unique lifestyle and food culture.
Uighur villages in Xinjiang have always maintained their traditional way of life and eating habits, have their own language, and do not marry outside the ethnic group. Naturally, it can be speculated that the bifidobacteria isolated from the feces of Uygur people have more potential to be developed into probiotic products suitable for this ethnic group.
Studies on the probiotic properties of human bifidobacteria have been reported. Liu et al. However, there are few reports on the development of probiotics among ethnic minorities in China, especially for the anti-oxidation bifidobacteria.
Therefore, the main purpose of this study is in vitro to evaluate the safety and effectiveness of indigenous Bifidobacterium strains isolated, by examining their probiotic properties with the emphasis on antioxidant activities, which provides an opportunity to develop new probiotics suitable for the intestinal physiological characteristics of Xinjiang Uygur.
Bifidobacteria is the most abundant species in the intestinal microbiota of infants, and its diversity decreases with the increase of age Turroni et al. Therefore, this study selected the specific group of infants of Uygur nationality.
Samples were taken from the feces of 28 breast-fed infants from the Uighur ethnic group of Xinjiang in northwest China. This study was conducted according to the guidelines of the Declaration of Helsinki. All procedures involving human subjects were then adopted by the Ethics Committee of the First Affiliated Hospital, Shihezi University School of Medicine In the preliminary research work, written informed consent was issued by all parents or guardians of participating infants.
Stools were serially diluted in sterile saline water. Respectively put μL of each dilution into modified deMan, Rogosa, and Sharpe MRS, Sigma medium supplemented with 0. Colonies with Y or V shape Gram-positive, catalase-negative were picked up.
Purification was repeated by thrice on modified MRS medium in order to ensure the purity of the cultures. Except for the modified MRS medium used in the process of strain isolation, MRS medium was used in the following experimental process for strain cultivation.
Genomic DNA was extracted according to the instructions of the bacterial genomic DNA extraction kit TIANGEN. Then, PCR products were purified and sequenced by Shenggong Biotechnology Co. Based on strain grouping result obtained by 16S rRNA gene analysis, all isolates were subjected to accurate genetic identification throughout multiplex-PCR, using species-specific primers targeting a conserved region of the tuf gene Ventura et al.
The nucleotide sequences were compared with sequences available at GenBank database using the BLAST program. The antagonism towards various bacterial pathogens and common bacteria present in the GI tract was evaluated according to the Oxford cup method Argyri et al.
Respectively, the cell-free supernatant CFS produced from seventy-five isolates were tested in duplicate against the indicator bacteria Escherichia coli EPEC O K63 CICCEscherichia coli ETEC O K80 CICCEscherichia coli EHEC O H7 CICCSalmonella typhimurium CICCListeria monocytogenes CGMCC 1.
enterica CGMCC 1. The three different Escherichia coli species were selected because they have different pathogenic effects in humans and are representative of the diarrheagenic Escherichia coli species. Those indicator bacteria were obtained from the China Industrial Microbial Culture Management Center.
Acid and bile salts tolerance test were determined as described by Arboleya et al. Briefly, strains were grown 28 h on MRS broth at 37°C under anaerobic conditions, and the cultured cell fluid was centrifuged at g for 5 min at 4°C and washed twice with 0. The cell pellet was re-suspended in PBS solution with different pH, i.
Then, the absorbed μL of these dilutions were applied to MRS agar plates at 37°C for 28 h under anaerobic conditions, and the number of colonies on the plate was used to determine the survival rate the viable cell count was recorded and compared with initial viable cell count, i.
For bile salt tolerance, survival rates for these strains were estimated at different pig bile salt concentrations 0. The experiment was carried out using the same experimental method as the acid resistance test and Compared with the treatment group cultured for 0 h under the same conditions same bile salt concentration.
In this case, the experiment was conducted in triplicates and take the average. The survival rate of strains after the exposure of simulated gastric fluid SGF and simulated intestinal fluid SIF were assessed according to Liao et al. The strain fermentation liquid 1 mL washed with 0.
Then, the samples that were exposed to simulated gastric juice min were harvested and washed with 0. The SIF containing bacteria was cultivated at 37°C for 60 and min under anaerobic conditions. The commercial probiotic Lactobacillus rhamnosus GG was treated in the same way as above for comparison.
Chloroform, xylene, and ethyl acetate were used to assess the electron donor basichydrophobic, and electron acceptor acidic characteristics of bacterial surface, respectively Kos et al.
The hydrophobicity is calculated according to the following equation:. where A 1 represents the absorption value at nm of the aqueous phase after mixing and phase separations and A 0 represents the absorption value at nm of original suspension.
It was expressed using the following:. Co-aggregation of bifidobacteria with pathogenic bacteria Escherichia coli EPEC O K63 CICC was evaluated as described by Solieri et al.
Extracellular fermentation supernatant EFS : The strains were grown in MRS broth at 37°C for 28 h to logarithmic growth phase under anaerobic conditions, and the culture solution were centrifuged at g, 4°C for 10 min.
The supernatant was collected for antioxidant activity test. Intact cells IC : The bacterial cells obtained by centrifugation were washed thrice with PBS solution pH 7.
The obtained solution was the bacterial solution required for antioxidant activity test. Intracellular cell extracts ICE : After the bacterial cells washed thrice with PBS solution, collected and sent to low temperature ultrasonic disruption W, working time 5 s, interval 5 s, 80 timesthen centrifuged at g for 20 min, the supernatant were collected as intracellular cell extract ICE for antioxidant activity test.
DPPH radical scavenging ability was measured with some modification Fan et al. The DPPH-free radical scavenging activity was counted as follows:. where A 0 represents the Abs of control group replaced the sample solution with distilled water, A 1 is the Abs of test sample reacting with DPPH, and A 2 is the Abs of blank group replaced the DPPH solution with an equal volume of absolute ethanol.
Hydroxyl radical scavenging test was conducted with modified method Ahire et al. The mixture is used to prepare hydroxyl radical which are composed of 1 mL of 0. The absorbance of the mixture was measured at nm.
The hydroxyl scavenging activity was calculated as follows:. where A 0 represents the Abs of control group replaced the sample solution with distilled water, A 1 is the Abs of sample solution reacting with hydroxyl radical, and A 2 is the Abs of blank group replaced the H 2 O 2 solution with distilled water.
The activity of scavenging superoxide anion was determined by a modified method Kuda et al.
