Abstract
One of the main lactic acid bacterial species found in the kefir grain ecosystem worldwide is Lactobacillus kefiranofaciens, exhibiting strong auto-aggregation capacity and, therefore, being involved in the mechanism of grain formation. Its occurrence and dominance in kefir grains of various types of milk and geographical origins have been verified by culture-dependent and independent approaches using multiple growth media and regions of the 16S rRNA gene, respectively, highlighting the importance of their combination for its taxonomic identification. L. kefiranofaciens comprises two subspecies, namely kefiranofaciens and kefirgranum, but only the first one is responsible for the production of kefiran, the water-soluble polysaccharide, which is a basic component of the kefir grain and famous for its technological as well as health-promoting properties. L. kefiranofaciens, although very demanding concerning its growth conditions, can be involved in mechanisms affecting intestinal health, immunomodulation, control of blood lipid levels, hypertension, antimicrobial action, and protection against diabetes and tumors. These valuable bio-functional properties place it among the most exquisite candidates for probiotic use as a starter culture in the production of health-beneficial dairy foods, such as the kefir beverage.

Abstract
Homogenized hydroponic ginseng (HG) fortified with poly-γ-glutamic acid (γ-PGA) and γ-aminobutyric acid (GABA) was produced by a two-step fermentation using Bacillus subtilis and Lactobacillus plantarum. For optimized production of bioactive compounds, the precursor monosodium L-glutamate (MSG) as well as nutrients such as glucose and skim milk were added. The homogenized HG was pH 6.93 and had an acidity of 0.08%, and viable cell count of 6.13 log colony-forming unit (CFU)/mL. The first (alkaline) fermentation was performed at 42°C for 2 days in the presence of 5% MSG and 2% glucose. The fermented HG was pH 8.08 and had an acidity of 0.03%, a mucilage of 2.13%, a consistency of 0.79 Pa·sn, and viable cell count of 8.53 log CFU/mL. For the second (lactic) fermentation, the fermented HG was fortified with 5% skim milk, inoculated with 7.54 log CFU/mL of L. plantarum EJ2014, and was incubated at 30°C for 5 days; the resulting in pH 5.63 and had and acidity of 0.35, and viable cell count of 6.71 log CFU/mL (B. subtilis) and 9.23 log CFU/mL (L. plantarum). Moreover, MSG was completely bio-converted with producing 1.03% GABA. Therefore, novel co-fermentation using B. subtilis HA and L. plantarum EJ2014 fortified HG with functional components including γ-PGA, GABA, peptides, and probiotics.

Abstract
Milk proteins have attracted extensive interest in terms of their bioavailability following ingestion. Enzymatic digestion of dairy products generates numerous peptides with various biological activities. Both human milk and infant formulas based on cow's milk are potential sources of bioactive peptides. This review aims to present current knowledge on the formation and fate of bioactive peptides from milk feeds intended for infants. Emphasis is placed on the source of the bioactive peptides with the nutritional impact of human milk and cow milk-based formulas on infant health being critically discussed from that perspective. Furthermore, the effect of processing and in vitro or in vivo digestion on the release and availability of peptides with bioactive sequences is evaluated. Considerable differences with respect to bioavailability and metabolic effects between the biologically active fragments generated following ingestion of human milk and infant formulas are documented. Peptides from milk protein of bovine origin could be a valuable supplement to human milk as multiple health-promoting properties are attributed to peptide fractions identified in standard cow milk-based infant formulas.

Abstract
Animal and human studies suggest that a malleable protein matrix (MPM) from whey decreases plasma lipid concentrations and may positively influence other components of the metabolic syndrome such as glucose metabolism and blood pressure (BP). The primary objective of this double-blind, multi-centre trial was to investigate the effects of a low-fat yoghurt supplemented with whey MPM on fasting TAG concentrations in patients with the metabolic syndrome. A total of 197 patients were randomised to receive MPM or a matching placebo yoghurt identical in protein content (15 g/d). Patients were treated during 3 months with two daily servings of 150 g yoghurt each to compare changes from baseline in efficacy variables. MPM treatment resulted in a significantly larger reduction of TAG concentrations in comparison to placebo (relative change -16%, P=0·004). The difference was even more pronounced in subjects with elevated fasting TAG (≥200 mg/dl) at baseline (-18%, P=0·005). The relative treatment difference in fasting plasma glucose was -7·1 mg/dl (P=0·089). This effect was also more pronounced in subjects with impaired fasting glucose at baseline (-11 mg/dl, P=0·03). In patients with hypertension, the relative treatment difference in systolic BP reached -5·9 mmHg (P=0·054). The relative treatment difference in body weight was -1·7 kg (P=0·015). The most common adverse events were gastrointestinal in nature. Conclusions from the present study are that consumption of a low-fat yoghurt supplemented with whey MPM twice a day over 3 months significantly reduces fasting TAG concentrations in patients with the metabolic syndrome and improves multiple other cardiovascular risk factors.

Abstract
Previously, we reported that a malleable protein matrix (MPM), composed of whey fermented by a proprietary Lactobacillus kefiranofaciens strain, has immunomodulatory and anti-inflammatory properties. MPM consumption leads to a considerable reduction in the cytokine and chemokine production (tumor necrosis factor-alpha, interleukin-1beta, and interleukin-6), thus lowering chronic inflammation or metaflammation. Inhibition of metaflammation should provide positive impact, particularly in the context of dyslipidemia, insulin resistance, and hypertension. In this study, we investigated whether short-term MPM supplementation ameliorates those features of metabolic syndrome (MetS). The ability of MPM to potentially regulate triglyceride level, cholesterol level, blood glucose level, and hypertension was evaluated in different animal models. MPM lowers triglyceride level by 37% (P < .05) in a poloxamer 407 dyslipidemia-induced rat model. It also reduces total cholesterol by 18% (P < .05) and low-density lipoprotein-cholesterol level by 32% (P < .05) and raises high-density lipoprotein-cholesterol level by 17% (P < .01) in Syrian Golden hamsters fed a high fat/high cholesterol diet for 2 weeks. MPM reestablishes the fasting glucose insulin ratio index to normal levels (P = .07) in this latter model and lowers the plasma glucose level area under the curve (-10%, P = .09) in fructose-fed rats after 2 weeks of treatment. In spontaneously hypertensive rats, MPM-treated animals showed a reduction of SBP by at least 13% (P < .05) for 4 weeks. Results from this study suggest that MPM is a functional ingredient with beneficial effects on lipid metabolism, blood glucose control, and hypertension that might contribute to the management of MetS and thus reducing the risk of cardiovascular diseases.

Abstract
Bovine milk-derived products, in particular whey proteins, exhibit beneficial properties for human health, including the acquired immune response. However, their effects on innate immunity have received little attention. Neutrophils are key cells of innate defenses through their primary functions of chemotaxis, phagocytosis, oxidative burst, and degranulation. A whey protein extract (WPE) purified from bovine lactoserum was evaluated for its direct and indirect effects on these primary functions of normal human blood neutrophils in vitro. Although WPE had no direct effects on primary functions, a 24-h pretreatment of neutrophils with WPE was associated with a significant and dose-dependent increase of their chemotaxis, superoxide production, and degranulation in response to N-formyl-methionine-leucine-phenylalanine, as well as of their phagocytosis of bioparticles. The pretreatment increased the surface expression of CD11b, CD16B, and CD32A receptors. The major WPE protein components beta-lactoglobulin (beta-LG) and alpha-lactalbumin (alpha-LA) were the main active fractions having an additive effect on human neutrophils that became more responsive to a subsequent stimulation. This effect on NADPH oxidase activity was associated with translocation of p47(phox) to plasma membrane. Glycomacropeptide, a peptide present in measurable amounts in WPE products, was able to enhance the individual effect of beta-LG or alpha-LA on neutrophils. The present data suggest that WPE, through beta-LG and alpha-LA, has the capacity to enhance or "prime" human neutrophil responses to a subsequent stimulation, an effect that could be associated with increased innate defenses in vivo.

Abstract
PURPOSE OF REVIEW Muscle protein synthesis (MPS) and muscle protein breakdown are simultaneous ongoing processes. Here, we examine evidence for how protein quality can affect exercise-induced muscle protein anabolism or protein balance (MPS minus muscle protein breakdown). Evidence is highlighted showing differences in the responses of MPS, and muscle protein accretion, with ingestion of milk-based and soy-based proteins in young and elderly persons. RECENT FINDINGS Protein consumption, and the accompanying hyperaminoacidemia, stimulates an increase in MPS and a small suppression of muscle protein breakdown. Beyond the feeding-induced rise in MPS, small incremental addition of new muscle protein mass occurs following intense resistance exercise which over time (i.e. resistance training) leads to muscle hypertrophy. Athletes make use of the paradigm of resistance training and eating to maximize the gains in their skeletal muscle mass. Importantly, however, metabolically active skeletal muscle can offset the morbidities associated with the sarcopenia of aging such as type II diabetes, decline in aerobic fitness and the reduction in metabolic rate that can lead to fat mass accumulation. SUMMARY Recent evidence suggests that consumption of different proteins can affect the amplitude and possibly duration of MPS increases after feeding and this effect interacts and is possibly accentuated with resistance exercise.

Abstract
Background Over the last 10 years, whey proteins have received considerable attention in the area of functional foods and nutraceuticals. In this paper, a novel fermented whey protein-based product described as a gel-like Malleable Protein Matrix (MPM) has been tested for its anti-inflammatory activity. Preliminary in vitro results have already indicated that MPM could exert such an anti-inflammatory activity. Methods The systemic anti-inflammatory activity of the MPM was explored using the oxazolone-induced atopic contact dermatitis mouse model (ACD). Parameters including ear thickness, side effects as well as neutrophil extravasation were monitored. Results In the ACD model, the MPM exhibited an anti-inflammatory effect comparable to that of hydrocortisone (positive control). Mice fed with MPM showed strong reduction of the ear inflammation while no side effects, as compared to hydrocortisone, were observed. The MPM seemed to reduce neutrophil extravasation in tissue as evidenced by blood polymorphonuclear cells and ear myeloperoxidase content. Conclusion The anti-inflammatory activity demonstrated in the ACD model suggests that the mechanism of action of the MPM is different than that of hydrocortisone and could become a relevant product for people suffering from dermatological manifestations associated with immune dysfunctions such as allergies, eczema, dermatitis, and autoimmune diseases.
