Introduction. Kurunga is a dairy drink made of a mix of lactic acid and alcoholic fermentation, characterized by high biological value based on protein composition, amino acid spectrum, fatty acid composition of lipids, vitamin and mineral substances, and physiological activity of microbiota containing lactobacilli, lactococci, bifidobacteria, and yeast. Among the probiotic correctors of normal microbiota isolated from national products, lactobacilli was of particular interest, with regards to a therapeutic – preventive effect. The aim of the study was to examine the probiotic properties of lactobacilli from kurunga.Methods. We isolated lactic acid bacteria strains from kurunga. The isolated cultures were identified using common microbiological methods and phylogenetic analysis. The antibiotic activities of these strains were determined by measuring the growth inhibition zone of test cultures. The probiotic properties were measured as levels of resistance to bile and hydrochloric acids, in addition to the presence of superoxide dismutase (SOD) activity using the xanthine oxidase-cytochrome method. Proteolitic activity was determined at the various levels of pH (3.0, 4.2, 5.3, and 7.0).Results. According to the morphological, cultural, physiological, biochemical properties and the genotypic analysis of the oligonucleotides sequence of  specific genes, the most effective strain was  identified as Lactobacillus diolivorans KL-2 (GenBank database KC438372). The isolated strain suppressed the growth of Gram-positive bacteria, such as Bacillus, Staphylococcus, and Listeria sp., as well as Gram-negative bacteria, such as E.coli, Proteus, Salmonella sp. They also possessed fungicidal action (based on Penicillum, Aspergillus sp, and Candida sp.).  The strain was resistant to the action of the bile acids at concentrations of 0.8% to 1.0% and hydrochloric acid. The strain KL-2 possessed a relatively high SOD activity (25.74 U/mg of protein), a low proteolytic activity at a pH 3.0 (4.74·10-3 PU/ml), and high proteolytic activity at pH 4.2 (294.74·10-3 PU/ml), pH 5.3 (330.52·10-3 PU/ml) and pH 7.0 (713.68·10-3 PU/ml).Conclusion. The unique properties of this strain, such as stability in the gastrointestinal tract, the wide spectrum of bactericidal and fungicidal action to the pathogenic species, the relatively high superoxide dismutase and proteolytic activities, and the absence of  toxicity, make it a prime candidate for probiotic culturing.

BACKGROUND: It is a national priority to look for new probiotic bacteria with highly active biological properties to create a new generation of probiotics, ferments, therapeutic, and prophylactic fermented milk products, taking into account ethnocultural and regional characteristics. AIM: The aim of the study is to assess probiotic properties of strains of lactobacilli (antimicrobial and adhesive), which are isolated from national lactic acid products from different districts of the Karaganda region (Kazakhstan). MATERIALS AND METHODS: There were modern microbiological methods applied during the experiment. To determine the morpho-cultural properties, the following methods were used: Gram staining, a catalase test, serial dilutions. The Matrix Supported Laser Desorption/Ionization Flight Time Mass Spectrometry was used for identification, and the deferred-antagonism method was used to determine the antimicrobial activity. The buccal epithelial cells were used for the cell object as a test system to determine the adhesive activity. RESULTS: In this experiment, 26 lactobacillus isolates were isolated from 68 samples of national lactic acid products produced in a traditional homemade way in different districts of the Karaganda region (Kazakhstan). As a result of the studies carried out on the cultural and morphological characteristics and identification by the mass spectrometer, the following lactobacilli were obtained: Lactobacillus acidophilus (two strains), Lactobacillus delbrueckii subsp. bulgaricum (two strains), Lactobacillus rhamnosus (seven strains), Lactobacillus plantarum (two strains), Lactobacillus paracasei (11 strains), and Lactobacillus fermentum (two strains). Twenty-six isolates of lactobacilli were tested for antimicrobial activity, 13 isolates of which showed an inhibitory effect, but the degree of antagonism varied among lactobacillus isolates. In general, the inhibitory activity of lactobacillus isolates was shown against the Gram-negative indicator microorganisms Salmonella typhimurium NCTC 12023, Escherichia coli NCTC 12923. The antibacterial activity was shown against the Staphylococcus aureus NCTC 12973 indicator microorganism in nine isolates of lactobacilli. Only six isolates of lactobacilli showed antifungal activity against the test strain of Candida albicans NCPF 3179. Out of 13 isolates of lactobacilli, nine isolates of medium and high activity competed for binding to buccal epithelial cells. CONCLUSION: The obtained isolates from traditional dairy products are considered to be promising candidates and competitive isolates with some probiotic potential. This study calls for further researches to be made in this area.

This study aims to assess the probiotic properties of Lactic Acid Bacteria isolated from the traditional sourdoughs used for bread making in Turkey against some gut conditions. A total number of 29 samples from twelve provinces of Turkey were collected, and screened for the presence of lactic acid bacteria using microbiological methods. The microbiological screening yielded 148 presumptive isolates. Of them, 62.8% were characterized as lactic acid strains by VITEK® MS. Following that, the characterized isolates were subjected to probiotic property testing, including gastric acid resistance, bile resistance and hydrophobic ability. The results showed that 44.1% exceeded gastric pH resistance, 33.3% survived under gastrointestinal system bile salt conditions, and 10.8% exhibited high hydrophobicity ability. In conclusion, our study revealed that only 4.3% (1 Enterococcus faecium, 1 Lactobacillus brevis, 1 Lactobacillus pentosus, and 1 Lactobacillus plantarum) out of 93 lactic acid bacteria isolated from the traditional sourdoughs could meet all probiotic requirements against some gut conditions.

This study aimed to determine the probiotic potential of Pediococcus acidilactici M76 (PA-M76) for lactic acid fermentation of black raspberry extract (BRE). PA-M76 showed outstanding probiotic properties with high tolerance in acidic GIT environments, broad antimicrobial activity, and high adhesion capability in the intestinal tract of Caenorhabditis elegans. PA-M76 treatment resulted in significant increases of pro-inflammatory cytokine mRNA expression in macrophages, indicating that PA-M76 elicits an effective immune response. When PA-M76 was used for lactic acid fermentation of BRE, an EPS yield of 1.62 g/L was obtained under optimal conditions. Lactic acid fermentation of BRE by PA-M76 did not significantly affect the total anthocyanin and flavonoid content, except for a significant increase in total polyphenol content compared to non-fermented BRE (NfBRE). However, fBRE exhibited increased DPPH radical scavenging activity, linoleic acid peroxidation inhibition rate, and ABTS scavenging activity of fBRE compared to NfBRE. Among the 28 compounds identified in the GC-MS analysis, esters were present as the major groups. The total concentration of volatile compounds was higher in fBRE than that in NfBRE. However, the undesirable flavor of terpenes decreased. PA-M76 might be useful for preparing functionally enhanced fermented beverages with a higher antioxidant activity of EPS and enhanced flavors.

On the frame of this research survey, a novel potentially probiotic strain (Lactobacillus paracasei SP5) recently isolated from kefir grains was evaluated for chokeberry juice fermentation. Chokeberry juice was retrieved from the variety Aronia melanocarpa, a plant known to provide small, dark berries and to be one of the richest sources of antioxidants. The juice was subsequently fermented inoculating L. paracasei SP5 for 48 h at 30 °C. The fermented juices were left at 4 °C and tested regarding microbiological and physicochemical characteristics for 4 weeks. The potentially probiotic strain was proved capable of performing lactic acid fermentation at 30 °C. Cell viability of L. paracasei was detected in high levels during fermentation and the whole storage period, while the fermented juice showed higher levels of viability in juice with 40.3 g/L of initial sugar concentration. No ethanol was detected in the final fermented juice. Fermented chokeberry juice was characterized by aromatic desirable volatiles, which were retained in adequate levels for the whole storage period. Specifically, the occurrence of organic esters detected in fermented juices is considered as positive evidence of the provision of fruity and floral notes to the final product. During storage, total phenolics content and antioxidant activity were observed in higher levels in fermented chokeberry juice compared with non-fermented juice. Subsequently, fermentation of chokeberry juice by potentially probiotic lactic acid bacteria could provide high industrialization potential, providing the market with a nutritional beverage of good volatile quality with an enhanced shelf-life compared with an unfermented fresh juice.

Renal Responses

To examine the functional interaction between superoxide dismutase (SOD) and NADPH oxidase activity, we assessed renal responses to acute intra-arterial infusion of ANG II (0.5 ng·kg−1·min−1) before and during administration of a SOD inhibitor, diethyldithiocarbamate (DETC, 0.5 mg·kg−1·min−1), in enalaprilat-pretreated (33 μg·kg−1·min−1) rats ( n = 11). Total (RBF) and regional (cortical, CBF; medullary; MBF) renal blood flows were determined by Transonic and laser-Doppler flowmetry, respectively. Renal cortical and medullary tissue NADPH oxidase activity in vitro was determined using the lucigenin-chemiluminescence method. DETC treatment alone resulted in decreases in RBF, CBF, MBF, glomerular filtration rate (GFR), urine flow (V), and sodium excretion (UNaV) as reported previously. Before DETC, ANG II infusion decreased RBF (−18 ± 3%), CBF (−16 ± 3%), MBF [−5 ± 6%; P = not significant (NS)], GFR (−31 ± 4%), V (−34 ± 2%), and UNaV (−53 ± 3%). During DETC infusion, ANG II also caused similar reductions in RBF (−20 ± 4%), CBF (−19 ± 3%), MBF (−2 ± 2; P = NS), and in GFR (−22 ± 7%), whereas renal excretory responses (V; −12 ± 2%; UNaV; −24 ± 4%) were significantly attenuated compared with those before DETC. In in vitro experiments, ANG II (100 μM) enhanced NADPH oxidase activity both in cortical [13,194 ± 1,651 vs. 20,914 ± 2,769 relative light units (RLU)/mg protein] and in medullary (21,296 ± 2,244 vs. 30,597 ± 4,250 RLU/mg protein) tissue. Application of DETC (1 mM) reduced the basal levels and prevented ANG II-induced increases in NADPH oxidase activity in both tissues. These results demonstrate that renal excretory responses to acute ANG II administration are attenuated during SOD inhibition, which seems related to a downregulation of NADPH oxidase in the deficient condition of SOD activity.

Superoxide dismutase (SOD) is a radical-scavenging enzyme. We determined Cu, Zn-SOD concentrations and activities in platelets from subjects with migraine and tension-type headaches. Thirty migraine without aura (MWoA) patients, 9 migraine with aura (MWA) patients, and 53 tension-type headache patients were selected for study. Thirty healthy volunteers composed the control group. Concentrations of platelet SOD were determined using enzyme-linked immunosorbent assay techniques. The activity of platelet SOD was determined by measuring reductivity of nitroblue tetrazolium. Low concentrations of platelet SOD were found in patients with MWA and MWoA. Platelet SOD activity decreased in MWA patients but not in patients with MWoA or tension-type headaches. These findings suggest vulnerability to oxidative stress in patients with migraine. It is suggested that low platelet SOD levels may play an important role in the etiology of migraine.

The present study was designed to assess the effects and potential mechanisms of ginsenosides on 17[Formula: see text]-ethynyelstradiol (EE)-induced intrahepatic cholestasis (IC). Ginsenoside at doses of 30, 100, 300[Formula: see text]mg/kg body weight was intragastrically (i.g.) given to rats for 5 days to examine the effect on EE-induced IC. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total bile acid (TBA) were measured. Hepatic malondialdehyde (MDA) content and superoxide dismutase (SOD) activity were determined. Protein expression of proinflammatory cytokines TNF-[Formula: see text], IL-6 and IL-1[Formula: see text] was analyzed by immunohistochemistry and Western blot. Results indicated that ginsenosides remarkably prevented EE-induced increase in the serum levels of AST, ALT, ALP and TBA. Moreover, the elevation of hepatic MDA content induced by EE was significantly reduced, while hepatic SOD activities were significantly increased when treated with ginsenosides. Histopathology of the liver tissue showed that pathological injuries were relieved after treatment with ginsenosides. In addition, treatment with ginsenosides could significantly downregulate the protein expression of TNF-[Formula: see text], IL-6 and IL-1[Formula: see text] compared with EE group. These findings indicate that ginsenosides exert the hepatoprotective effect on EE-induced intrahepatic cholestasis in rats, and this protection might be attributed to the attenuation of oxidative stress and inflammation.
