Characterization of two new strains of Lactococcus lactis for their probiotic efficacy over commercial synbiotics consortia. Braz J Microbiol 2022; 53:903-920. [PMID: 35138631 PMCID: PMC9151986 DOI: 10.1007/s42770-022-00685-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 01/02/2022] [Indexed: 02/01/2023] Open
Abstract
Lactococcus spp. are industrially crucial lactic acid bacteria (LAB) used to manufacture lactic acid, pickled vegetables, buttermilk, cheese, and many kinds of delicious dairy foods and drinks. In addition to these, they are also being used as probiotics in specific formulations. However, their uses as probiotics are comparatively less than the other LAB genera. The present communication hypothesizes to validate the probiotic potentiality of two new Lactococcus lactis subsp. lactis strains for their future uses. These native food fermenting strains were characterized for in vitro acid tolerance, tolerance to simulated gastric and pancreatic juices, autoaggregation and co-aggregation, hydrophobicity, haemolytic activity, bile salt deconjugation, cholesterol removal, antimicrobial spectrum, and antibiotic sensitivity. The in vivo live bacterial feeding of these strains for 30 days was done in Swiss albino mice either singly or in combination with prebiotic inulin and evaluated for hypocholesterolemic activity, immune enhancement, and gut colonization efficiency and compared with the commercial probiotic consortia. The study revealed that the strains could survive in human gut bile concentration, gastric pH conditions at pH 2.0, 3.0, and 8.0 for 6 h, had a broad antibacterial spectrum, and cholesterol binding efficacy. The strains could survive with higher colony-forming units (CFU/mL) when amended with sodium caseinate. The strains had autoaggregation ranges from 15 to 25% over 24 h and had a significant co-aggregation with both lactic acid and Gram-positive and Gram-negative bacterial strains related to human illness. The strains also showed solvent and media-specific hydrophobicity against n-hexane and xylene. The live bacterial feeding either singly or in combination with prebiotic inulin resulted in a significant reduction of LDL (low-density lipoprotein), VLDL (very low-density lipoprotein) cholesterol and triglyceride (TG), and a significant increase in HDL (high-density lipoprotein) cholesterol level, and improved gut colonization and gut immunomodulation. The results prove that these non-haemolytic, non-toxic strains had significant health benefits than the commercial probiotics consortium with the recommended prebiotics mix. Thus, these new Lactococcus lactis subsp. lactis strains could be trialled as a new probiotic combination for human and animal feeds.

Abstract
The microalga Chlorella and strains of Bifidobacterium have been used in human or animal food supplements for decades because of their positive health effects. The presented study assessed different properties of C. vulgaris and its combination with bifidobacteria with the aim to develop new functional foods. The growth of four bifidobacteria strains in milk and whey supplemented with 1.0% (w/v) C. vulgaris and the immunomodulatory effects of aqueous Chlorella solutions (0.5%, 1.0%, and 3.0%) on human peripheral mononuclear cells were evaluated. Furthermore, synergistic effects on lipid metabolism of rats fed a high-fat diet with Chlorella and B. animalis subsp. lactis BB-12® were analysed. Chlorella had a positive growth-promoting effect on the tested bifidobacteria (p < 0.05), and significantly increased the secretion of inflammatory cytokines (tumor necrosis factor-α, interleukin-10, and interleukin-6), depending on the concentration of Chlorella (p < 0.05). After 8 weeks, significant synergistic effects of Chlorella and bifidobacteria on triglyceride levels in rat heart, liver, and serum were observed (p < 0.05). These results demonstrate that various combinations of Chlorella and bifidobacteria have significant potential for the development of new fermented products, dependent on the algal species, probiotic strain, application form, and concentrations for acceptable sensory quality for consumers.

Abstract
BACKGROUND Probiotics have been associated with many beneficial effects in human digestive physiology. The aim of this study was to evaluate the effect of improved formulation of chitosan-alginate microcapsules of Bifidobacterium strains on serum triglycerides, cholesterol, HDL, and LDL in mice. METHODS Five approved probiotic strains of Bifidobacterium were tested for anti-proliferative effect and interleukin-8 induction on HT-29 cell lines. Bifidobacterium strains plus five approved Lactobacillus were encapsulated in chitosan-alginate microcapsules and tested for its survival in simulated gastrointestinal conditions. These microcapsules were administered to 4 groups of mice (including 1. Bif (Bifidobacterium strains), 2. Lac (Lactobacillus strains), 3. Bif-Lac (Bifidobacterium plus Lactobacillus strains) and 4. Control) for 8 days. At eighth day, the blood of mice were taken and serum levels of triglycerides, cholesterol, HDL, and LDL of them were determined. RESULTS All of the Bifidobacterium strains significantly (P < 0.001) reduced secretion of IL-8 in HT-29 cells as well as maximum antiproliferative effects (P < 0.001). In addition, all microcapsules showed impressive survival rate in bile (>%94.1) and gastrointestinal (>%78.28) conditions (P < 0.05). Only Bif-Lac group displayed significantly lower serum cholesterol and LDL levels than control group (P < 0.05). Besides, all groups indicate statistically significant weight loss of mice during the 8 days in comparison with the control group (P < 0.05). CONCLUSION The results of this study showed that the microencapsulated probiotics with alginate and chitosan had an effective mean of delivery of viable bacterial cells and non-pharmacological interventions use to reduce serum cholesterol and LDL levels in in-vivo condition.

Abstract
Our previous study reported that lactic acid bacteria (L. brevis OPK-3) isolated from kimchi ameliorated intracellular lipid accumulation in 3T3-L1 adipocyte. The current study explored potential roles of L. brevis OPK-3 (KLAB) on preventing body weight gain and its effect on the inflammatory response of adipose tissue. Male C57BL/6 mice (n = 10) were divided into four groups: normal diet with distilled water (NDC), high-fat diet with distilled water (HDC), high-fat diet with L-ornithine (OTC) or high-fat diet with KLAB. The KLAB supplement resulted in significantly lower body weight, lower epididymal fat tissue mass, and lower serum and hepatic TG levels than the HDC. KLAB supplementation improved serum cytokines, and real-time polymerase chain reaction (PCR) analysis showed significantly lower inflammatory cytokine mRNA levels in epididymal adipose tissue. These results suggest that the administration of KLAB inhibits the induction of inflammation in adipose tissue along with the inhibition of weight gain. Therefore, this study demonstrates the therapeutic and beneficial value of this strain produced during the fermentation of kimchi.

Abstract
The present study was conducted to isolate and characterise Pb-resistant lactic acid bacteria (LAB), and thus determine their potential for use as probiotics against Pb toxicity. A total of 107 Pb-resistant LAB strains were isolated from the gut content of Cyprinus carpio, of which 41 were established to be gram-positive and catalase-negative. Investigation of the Pb-binding ability of these isolated LAB identified seven strains (P2, P6, P7, P9, P16, P19 and P22) with comparatively high Pb-binding activities. These were selected for further screening to establish their Pb tolerance, anti-oxidative capacity and in vitro probiotic characteristics. Strain P16 exhibited both the highest Pb-binding and a relatively good antioxidant capacity. Furthermore, P16 displayed a high survival rate during 4 h of exposure to both low-pH (2.5-3.5) conditions and 10.0% fish bile, and a strong capacity to adhere to fish intestinal mucus (62.4%). Furthermore, P16 showed strong antibacterial activities against all tested fish pathogens. Strains P6, P9, P16, P19 and P22 were susceptible to a range of tested antibiotics, but not to vancomycin. Thus, of the isolated lactobacilli, strain P16 exhibited the best Pb-binding ability, a high level of antioxidant activity and satisfactory in vitro probiotic properties. Biochemical and 16S-rRNA gene analyses identified P16 as Lactobacillus reuteri. Thus, the results of the conducted in vitro tests suggest that the fish-associated P16 Lact. reuteri strain is a promising candidate probiotic, which should undergo further investigation to assess its suitability for use in protecting against lead-exposure-induced toxicities in aquaculture.

Abstract
Antioxidant peptides are currently the focus of many studies, since they eliminate free radicals in the human body without harmful effects. In the present study, Lactobacillus casei L61 was used as a starter culture to ferment goat milk because of its high capacity to produce antioxidant peptides. An optimal nutrients formula (casein, casein peptone, glucose, soybean peptone, inulin, calcium lactate, and cysteine) was investigated by Plackett⁻Burman (P⁻B) and Box⁻Behnken (B⁻B) designs for response surface methodology (RSM). Antioxidant peptides were successively isolated and purified from the fermented goat milk. Furthermore, the stability of the antioxidant peptides was evaluated in a simulated gastrointestinal tract at 37 °C. The results showed that calcium lactate, glucose, and casein peptone significantly affected the antioxidant activity of goat milk. The optimal additive amounts were 0.99% (w/v) calcium lactate, 0.21% (w/v) glucose, and 0.29% (w/v) casein peptone. The hydroxyl free radical scavenging rate increased significantly (p < 0.001) from 56.50 ± 0.57% to 88.01 ± 0.69%; the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging rate increased up to 63.48 ± 1.22% under the optimal conditions (n = 3). Our research provides a fitted mathematical model for antioxidant peptides production. Besides, these antioxidant peptides had great stability during simulated gastrointestinal digestion.

Abstract
Twelve previously isolated Lactobacillus strains were investigated for their in vitro bioactivities, including bile salt hydrolase (BSH), cholesterol-reducing and antioxidant activities, cytotoxic effects against cancer cells, enzyme activity, and biogenic amine production. Among them, only 4 strains showed relatively high BSH activity, whereas the rest exhibited low BSH activity. All 12 strains showed cholesterol-reducing and antioxidant activities, especially in their intact cells, which in most of the cases, the isolated strains were stronger in these activities than the tested commercial reference strains. None of the tested strains produced harmful enzymes (β-glucosidase and β-glucuronidase) or biogenic amines. Among the 12 strains, 3 strains were tested for their cytotoxic effects against 3 cancer cell lines, which exhibited strong cytotoxic effects, and they also showed selectivity in killing cancer cells when compared to normal cells. Hence, all 12 Lactobacillus strains could be considered good potential probiotic candidates because of their beneficial functional bioactivities. PRACTICAL APPLICATION The Lactobacillus strains tested in this study could be considered good potential probiotic candidates for food/feed industry because of their beneficial functional bioactivities such as good cholesterol-reducing ability, high antioxidant activity, and good and selective cytotoxic effect against cancer cells.

Abstract
Probiotics have become highly recognized as supplements for humans and animals because of their beneficial effects on health and well-being. The present review aims to provide an overview of different steps through which microbial strains become applicable probiotics in food and/or feed industries. Isolation of potential probiotic strains is the first step. Lactic acid bacteria are the most frequently used microorganisms as probiotics, which can be isolated from human, animal, plant, and environment. The next steps are identification of the isolates and characterization of them based on the main selection criteria for any potential probiotic microorganism, including resistance to gastric acidity and bile salt, adherence to mucus and/or intestinal epithelial cells and cell lines, and antimicrobial and antagonism activity against potentially pathogenic microbes. There are additional probiotic properties that may be considered for selection of probiotic strains with specific effects, such as cholesterol reduction ability, antioxidant activity, or cytotoxic effect against cancer cells. However, a potential probiotic does not need to fulfill all such selection criteria. As the last step, safety status of probiotics for humans is verified by taxonomy clarification, in vitro and in vivo tests, human trials, and genome sequencing.

Abstract
The probiotic potential of lactic acid bacteria primarily point toward colonizing ability of Lactobacilli as the most important attribute for endowing all the known beneficial effects in a host. Lactobacillus species exert health-promoting function in the gastrointestinal tract through various mechanisms such as pathogen exclusion, maintenance of microbial balance, immunomodulation, and other crucial functions. It has been seen that many surface layer proteins are involved in host adhesion, and play significant role in the modification of some signaling pathways within the host cells. Interaction between different bacterial cell surface proteins and host receptor has been imperative for a better understanding of the mechanism through which Lactobacilli exert their health-promoting functions.

Abstract
Thirty-two lactic acid bacteria (LAB) isolates were obtained from fermenting cassava mash and wara (African soft cheese) and screened for their resistance to cadmium and lead toxicities at 550-1050 mg l-1 and probiotic potentials. Four LAB strains that tolerated the heavy metals at 1050 mg l-1 were selected for antioxidative capacities, tolerance to acid, bile salts and simulated gastric and intestinal tract and safety status. The results revealed that Weissella cibaria WD2 and Lactobacillus plantarum CaD1 exhibited comparatively higher antioxidative capacities, survived in simulated gastric and intestinal transit, tolerated acid and bile salt and possessed safety status. The two strains were employed for the in vivo studies, which was monitored in male albino Wistar rats using skim milk as a carrier for the cultures over a period of 28 days. The rats given the cultures of W. cibaria WD2 and L. plantarum CaD1 in addition with the administration of heavy metals had improved renal and hepatic impairment, while damage was observed in rats fed with cadmium and lead only. Weissella cibaria WD2 and L. plantarum CaD1 demonstrated probiotic potentials and safety status. These strains can be used to effectively amend hepatic and renal histopathological alterations in rats caused by ingestion of cadmium and lead. SIGNIFICANCE AND IMPACT OF THE STUDY This present study highlights the presence of lactic acid bacteria (LAB) from traditional fermented foods that were cadmium and lead resistant and possessed probiotic potentials. Weissella cibaria WD2 and Lactobacillus plantarum CaD1 selected for the in vivo studies ameliorated the build-up of cadmium and lead in the organs of the animals. This indicated that good cadmium and lead binding and probiotic lactic acid bacteria can be used to prevent exposure to these heavy metals.

Abstract
High ambient temperature is a major problem in commercial broiler production in the humid tropics because high producing broiler birds consume more feed, have higher metabolic activity, and thus higher body heat production. To evaluate the effects of two previously isolated potential probiotic strains (Lactobacillus pentosus ITA23 and Lactobacillus acidophilus ITA44) on broilers growing under heat stress condition, a total of 192 chicks were randomly allocated into four treatment groups of 48 chickens each as follows: CL, birds fed with basal diet raised in 24 °C; PL, birds fed with basal diet plus 0.1 % probiotic mixture raised in 24 °C; CH, birds fed with basal diet raised in 35 °C; and PH, birds fed with basal diet plus 0.1 % probiotic mixture raised in 35 °C. The effects of probiotic mixture on the performance, expression of nutrient absorption genes of the small intestine, volatile fatty acids (VFA) and microbial population of cecal contents, antioxidant capacity of liver, and fatty acid composition of breast muscle were investigated. Results showed that probiotic positively affected the final body weight under both temperature conditions (PL and PH groups) compared to their respective control groups (CL and CH). Probiotic supplementation numerically improved the average daily gain (ADG) under lower temperature, but significantly improved ADG under the higher temperature (P < 0.05) by sustaining high feed intake. Under the lower temperature environment, supplementation of the two Lactobacillus strains significantly increased the expression of the four sugar transporter genes tested (GLUT2, GLUT5, SGLT1, and SGLT4) indicating probiotic enhances the absorption of this nutrient. Similar but less pronounced effect was also observed under higher temperature (35 °C) condition. In addition, the probiotic mixture improved bacterial population of the cecal contents, by increasing beneficial bacteria and decreasing Escherichia coli population, which could be because of higher production of VFA in the cecum, especially at heat stress condition. The two Lactobacillus strains also improved the fatty acid profile of meat, including at heat stress. Generally, the two Lactobacillus strains can be considered as good potential probiotics for chickens due to their good probiotic properties and remarkable efficacy on broiler chickens.

Abstract
This study examined the effects of probiotic dahi prepared by Lactobacillus plantarum Lp9 and dahi culture in buffalo milk on lowering cholesterol in rats fed a hypercholesterolemic basal diet. Male Wistar rats were divided into 3 groups and fed with probiotic dahi, dahi, or buffalo milk for 120 days. Following the consumption of supplements (probiotic dahi, dahi or buffalo milk), the animals were fed a basal hypercholesterolemic diet. Plasma total cholesterol and triglycerides (TAGs) were decreased by 35% and 72% in rats fed with probiotic dahi group, while cholesterol levels increased by 70% and TAGs increased by 97% in buffalo milk and 59% in dahi fed groups. Supplementation of probiotic dahi further lowered plasma low-density lipoprotein (LDL) + very-low-density lipoprotein (VLDL)- cholesterol by 59%, while it elevated plasma high-density lipoprotein (HDL)-cholesterol by 116%. As a result, atherogenic index, the ratio of HDL to LDL + VLDL was markedly improved. Deposition of cholesterol and TAGs in liver and aorta were significantly reduced in rats fed with probiotic dahi. These observations suggest that probiotic dahi may have therapeutic potential to decrease plasma, hepatic and aortic lipid profile, and attenuate diet-induced hypercholesterolemia.

Abstract
By introducing aprN into Lactococcus lactis NZ9000, the genetically modified L. lactis NZ9000/pNZPNK successfully expressed the nattokinase. The safety assessment of this novel strain was based on allergenicity of pepsin digestion stability and murine model serologic identity. Subjecting to the GM strain and host to pepsin digestion, the soluble fractions and cell debris were fast degraded completely. Feeding with ovalbumin resulted in significantly higher production of IgG1 and IgE as compared to that of L. lactis NZ9000/pNZPNK or L. lactis NZ9000. Further, the serum IgG2a level increased dose-dependently at week 2 and induced immune reaction toward Th1 pathway. Secretion of cytokines IL-4 and IL-10 fed with lactococci was significantly lower than that of the OVA group. L. lactis NZ9000/pNZPNK did not increase the proliferation of type 2 helper T cells in spleen or induce allergenicity in BALB/c mice. On the basis of the results, the new GM lactic acid bacterium is regarded as safe to use.

Abstract
The aim of this study was to evaluate the antioxidant, antihypertensive and immunomodulatory characteristics of skim milk fermented with Lactobacillus delbrueckii ssp. bulgaricus LB340. Supernatants obtained from the ferments after centrifugation were subjected to ultrafiltration and yielded four peptidic fractions of 10-5 kDa, 5-3 kDa, 3-1 kDa, and <1·0 kDa. Peptides in 5-3 kDa range exhibited a good antioxidant activity. The peptides (<1·0 k) was applied to Superdex-30 G column fractionation and produced six fractions (F1-6). Fraction F2 presented the highest angiotensin I-converting enzyme inhibition activity with IC50 of 67·71 ± 7·62 mg/ml. Moreover, fraction F6, which displayed a good immunomodulatory activity, had a positive effect on murine spleen lymphocyte proliferation with Stimulation Index of 0·729 ± 0·123. The present data showed the potential of the milk fermented with Lactobacillus delbrueckii ssp. bulgaricus LB340 as a functional food, however, further research is needed to evaluate the biofunctional activity of this fermentation product in vivo using model animal.
