... Due to their high LA content, soybeans have the potential to produce CLA-rich foods through LAB fermentation [2]. In a study reported in 2015 [116], L. plantarum S48 and L. plantarum P1201 produced CLA1 and CLA2 isomers from 8% skim milk medium supplemented with three different free LA concentrations (0.25, 0.5 and 1 mg/mL) at 35 °C for 48 h. Subsequently, the authors conducted comparative tests on the production of CLA in 10% fresh, steamed, and roasted soypowder milk. ...
The term Conjugated Linoleic Acid (CLA) refers generically to a class of positional and geometric conjugated dienoic isomers of linoleic acid. Among the isomers of linoleic acid cis9, trans11-CLA (c9, t11-CLA) and trans10, cis12-CLA (t10, c12-CLA) are found to be bio-logically active isomers, and they occur naturally in milk, dairy products and meat from ruminants. In addition, some vegetables and some sea-foods have also been reported to contain CLA. Although the CLA levels in these natural sources are insufficient to confer the essential health benefits, anti-carcinogenic or anti-cancer effects are of current interest. In the rumen, CLA is an intermediate of isomerization and the biohydrogenation process of linoleic acid to stearic acid conducted by ruminal microorganisms. In addition to rumen bacteria, some other bacteria, such as Propionibacterium, Bifidobacterium and some lactic acid bacteria (LAB) are also capable of producing CLA. In this regard, Lactiplantibacillus plantarum (formerly Lactobacillus plantarum) has demon-strated the ability to produce CLA isomers from linoleic acid by multiple enzymatic activi-ties, including hydration, dehydration, and isomerization. L. plantarum is one of the most versatile species of LAB and the bacterium is widely used in the food industry as a micro-bial food culture. The studies reviewed in this article reveal how, in the production of some fermented foods, the use of appropriate strains of L. plantarum, as a starter or additional culture, can be considered a critical factor in the design of new CLA-enriched functional foods.

The composition of intestinal microflora plays an important role in human health as alteration in the gut microflora gives rise to various pathological diseases. This chapter discusses the concept of probiotics and prebiotics as well as the new emerging definitions being added to probiotic terminology, such as postbiotics, nutribiotics, and pharmabiotics. Probiotics are live microorganisms that when administered in adequate amounts confer a health benefit on the host microbes. The prebiotics act as foods for probiotics and provide health and physiological benefits to the host. Synbiotics are next-generation probiotics made with various formulations of probiotics and prebiotics that work in synergism to reestablish the healthy gut ecology. The postbiotics are soluble products or metabolic by-products secreted by live bacteria or released after bacterial lysis that offer health benefits to the host. They are relatively safer as they lack serious side effects as compared to probiotics. Nutribiotics are probiotics that confer nutritional functions by producing essential nutrients, such as vitamins and minerals, and converting precursors to bioactive metabolites. Pharmabiotics are probiotic products with a proven pharmacological action in health or disease.
... We previously reported that the antioxidant activity of soymilk was improved upon fermentation with L. plantarum P1201 under optimal conditions and that the fermented soy-powder milk (FSPM) contained high levels of isoflavone aglycones. Moreover, fermentation with L. plantarum can produce CLA, another bio-active substance, in soymilk (6,(15)(16)(17). In the present study, we aimed to determine isoflavone and CLA content, estimated the inhibitory activity of α-glucosidase, α-amylase, and pancreatic lipase and, the inhibitory effects on adipogenesis in a 3T3-L1 cells for FSPM and unfermented soy-powder milk (UFSPM Digestive enzyme inhibition assay α-Glucosidase inhibitory activity was determined in accordance with previously described method (17). ...
This study aimed to produce fermented soy-powder milk (FSPM) with Lactobacillus plantarum P1201 and to evaluate its anti-obesity activity. Isoflavone and conjugated linoleic acid (CLA) of unfermented soy-powder milk (UFSPM) and FSPM and were analyzed via high-pressure liquid chromatography (HPLC) and gas chromatography (GC). Their inhibitory activities against a-glucosidase, a-amylase, and pancreatic lipase were assayed. Their anti-obesity activities were evaluated on the basis of their inhibitory effects on adipocyte differentiation in 3T3-L1 cells, and the expression of mRNAs associated with adipogenesis and lipid metabolism were analyzed via real time-polymerase chain reaction (RT-PCR) and quantitative PCR (qPCR). FSPM with L. plantarum P1201 increased the isoflavone aglycones (daidzein, glycitein, and genistein) content and produced CLA in soy-powder milk (SPM), both of which possessed bio-activity. Both UFSPM and FSPM showed dose-dependent inhibitory activity for a-glucosidase, a-amylase, and pancreatic lipase. FSPM, but not UFSPM, suppressed adipogenesis in 3T3-L1 cells and reduced their triglyceride content by 23.1% after treatment with 1,000 μg/mL of FSPM, compared with the control group. The anti-obesity effect of FSPM can be attributed to CLA and isoflavone aglycones, which targeted CCAAT/enhancer binding protein a (C/EBP-α) and down-regulated lipoprotein lipase (LPL), adiponectin, adipocyte fatty acid-binding protein (aP2), fatty acid synthase (FAS), and acetyl CoA carboxylase (ACC) mRNA. Furthermore, FSPM enhanced the inhibitory activity of glucosidase and pancreatic enzymes and anti-obesity activity. Further studies are required to investigate whether the anti-obesity effect of FSPM persists in an in vivo mouse model of diet-induced obesity. © The Korean Society of Food Preservation.

Thus, in this review we critically analyzed the literature produced in the last ten years with the aim to highlight the potentiality as well as the optimal conditions for CLA production by L. plantarum. Evidence was provided suggesting that the use of appropriate strains of L. plantarum, as a starter or additional culture in the production of some fermented foods, can be considered a critical factor in the design of new CLA-enriched functional foods.
Probiotics are the most useful tools for balancing the gut microbiota and thereby influencing human health and disease. Probiotics have a range of effects, from those on nutritional status to medical conditions throughout the body from the gut to non-intestinal body sites such as the brain and skin. Research interest in probiotics with nutritive claims (categorized as nutribiotics) has evolved into interest in therapeutic and pharmacological probiotics with health claims (pharmabiotics). The concept of pharmabiotics emerged only two decades ago, and the new categorization of probiotics to nutribiotics and pharmabiotics was recently suggested, which are under the different regulation depending on that they are food or drug. Information of the gut microbiome has been continuously accumulating, which will make possible the gut microbiome-based healthcare in the future, when nutribiotics show potential for maintaining health while pharmabiotics are effective therapeutic tools for human diseases. This review describes the current understanding in the conceptualization and classification of probiotics. Here, we reviewed probiotics as nutribiotics with nutritional functions and pharmabiotics with pharmaceutic functions in different diseases.
This study was performed to investigate the ameliorating effects of steamed soybeans (SS) and fermented SS (FSS) on lipid metabolism in high-fat diet-induced obese mice. ICR mice were divided into four groups and given the following different diets: normal diet (ND), high-fat diet (HFD), HFD with 1% SS (HFD + SS), and HFD with 1% FSS (HFD + FSS). After 14 weeks, the body weight gain was higher in the HFD group compared with the ND group but lower in the HFD + FSS group compared with the HFD group. Plasma levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein-cholesterol, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were significantly higher in the HFD group compared to the ND group, but lower in the HFD + SS and HFD + FSS groups compared with the HFD group. In addition, leptin concentration in plasma was lower in the groups fed HFD + SS and HFD + FSS compared with the HFD group. The accumulation of hepatic TG and TC was significantly inhibited in the HFD + SS and HFD + FSS groups. Furthermore, SS and FSS attenuated lipid peroxidation and nitric oxide formation in the liver induced by the high-fat diet. These results suggest that soybeans, especially FSS, may be useful in preventing obesity-induced abnormalities in lipid metabolism.
