Abstract
Inflammatory bowel disease (IBD), characterized by chronic inflammation of the gut, is caused by several factors. Among these factors, microbial factors are correlated with the gut microbiota, which produces short-chain fatty acids (SCFAs) via anaerobic fermentation. Fermented foods are known to regulate the gut microbiota composition. Ganjang (GJ), a traditional fermented Korean soy sauce consumed worldwide, has been shown to exhibit antioxidant, anticancer, anti-colitis, and antihypertensive activities. However, its effects on the gut microbiota remain unknown. In the present study, we aimed to compare the anti-inflammatory effects of GJ manufactured using different methods and investigate its effect on SCFA production in the gut. To evaluate the anti-inflammatory effects of GJ in the gut, we performed animal experiments using a mouse model of dextran sulfate sodium (DSS)-induced colitis. All GJ samples attenuated DSS-induced colitis symptoms, including reduced colonic length, by suppressing the expression of inflammatory cytokines. In addition, GJ administration modulated SCFA production in the DSS-induced colitis model. Overall, GJ exerted anti-inflammatory effects by reducing DSS-induced symptoms via regulation of inflammation and modulation of SCFA levels in a DSS-induced colitis model. Thus, GJ is a promising fermented food with the potential to prevent IBD.

Jin YH, Mah JH. Culture-dependent and -independent analyses of bacterial compositions and its contributions to formation of γ-aminobutyric acid and poly-γ-glutamic acid in Cheonggukjang. Food Res Int 2024; 179:114026. [PMID: 38342543 DOI: 10.1016/j.foodres.2024.114026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 01/09/2024] [Accepted: 01/12/2024] [Indexed: 02/13/2024]
Abstract
This study was performed to unveil bacterial compositions and their contributions to the formation of γ-aminobutyric acid (GABA) and poly-γ-glutamic acid (γ-PGA) in Cheonggukjang. To predict possible key factors contributing to the content of the bioactive compounds in Cheonggukjang, commercial products were analyzed for various parameters. The content of GABA and γ-PGA showed a negative (R2 = 0.61 - 0.73) and positive correlation (R2 = 0.53 - 0.96) with antioxidative activity. Consistently, GABA content showed a moderate negative correlation with γ-PGA content (R2 = 0.58). Among the physicochemical and microbial parameters, only salinity showed a moderate negative correlation with γ-PGA content (R2 = 0.75), which might be due to the inhibition of bacterial growth. It was also suggested that multiple factors (including bacterial species) were involved in the formation of GABA and γ-PGA in Cheonggukjang. To reveal dominant bacterial species and further presume their contributions to the bioactive compound formation in Cheonggukjang, both culture-independent (metagenomic) and -dependent (culturomic) methods were used. Culture-independent method showed that Bacillus piscis was dominant (23.37 - 94.89 %), followed by B. hisashii (0.00 - 62.45 %) and B. coagulans (0.00 - 13.82 %). Considering the quantitative speciation data on the bioactive compound content in Cheonggukjang (and bacterial production capability) together, it was further elucidated that B. piscis contributed primarily to the bioactive compound formation. Unlike this, culture-dependent analysis revealed that B. licheniformis and B. subtilis were dominant (30.0 - 47.6 and 17.5 - 39.5 %, respectively). Based on the quantitative speciation data on the bacterial production capability of GABA and γ-PGA, B. subtilis was the primarily contributing bacterial species to the bioactive compound formation. Consequently, it was observed that the bacterial compositions and their contributions to the bioactive compound formation determined by the two methods differed considerably, i.e., B. piscis and B. subtilis were identified to be prominent bacterial contributors, respectively, depending on the method used.

Abstract
BACKGROUND Chronic constipation (CC) is a common gut health problem, and the role of live dietary microbes in CC is unclear. OBJECTIVE This study aimed to investigate the relationship between dietary live microbes consumption and CC. METHODS Using the National Health and Nutrition Examination Survey data (2005-2010), 11,170 adults who completed the 24-h face-to-face dietary recall and bowel health questionnaire were identified. CC was defined by the Bristol Stool Form Scale. Dietary live microbes intake was classified as low, medium, and high. Additionally, combined medium and high categories (MedHi) were analyzed. Multivariate regression models were constructed to assess the association between dietary intake of live microbes and CC. RESULTS In the weighted sample, the age-adjusted CC prevalence was 7.06% (95% confidence interval [CI]: 6.45, 7.67). In multivariate regression models, after controlling for potential confounders race/ethnicity, sex, body mass index, education, poverty, depression, caffeine intake, and alcohol intake, a significant inverse association between dietary live microbes consumption and CC was observed (odds ratio [OR]: 0.77, 95% CI: 0.61, 0.97, P-trend = 0.061). CONCLUSIONS Our findings suggest that a high dietary live microbes consumption may be associated with lower odds of CC. However, further prospective studies are essential to confirm its effectiveness in reducing CC occurrence.

Abstract
The prevalence of constipation, one of the common gastrointestinal (GI) diseases, has been gradually increasing. Gochujang, a traditional Korean fermented paste, has various microbiota and exerts diverse health beneficial effects. However, the ameliorative effect of Gochujang on constipation is unexplored. Seven-week-old ICR mice were divided into five groups: the normal group, the loperamide (LOP) group, the LOP + mosapride citrate (3 mg per kg BW, MOSA) treated group, the LOP + BMG Gochujang (2 g per kg BW) group, and the LOP + VMG Gochujang (2 g per kg BW) group. Gochujang alleviated constipation by increasing defecation frequency and water content in feces by reducing AQP3 mRNA expression. Additionally, Gochujang increased GI transit time and excitatory neurotransmitter levels and decreased inhibitory neurotransmitter levels. Moreover, Gochujang reduced mitogen-activated protein kinase (MAPK) activation and increased the c-Kit/SCF signaling pathway, suggesting that Gochujang regulates the enteric nervous system (ENS). Interestingly, BMG and VMG differently influenced the gut microbiota composition. Both Gochujang groups significantly decreased the Bacteroidetes and Firmicutes ratio compared to the LOP group. However, among Firmicutes genera, Acetatifactor was only reduced in BMG, and VMG only decreased Caproiciproducens and Acutalibacter. In summary, Gochujang effectively alleviated LOP-induced constipation outcomes regardless of their different microbial communities by ameliorating GI motility and changing the gut microbiota composition.

Abstract
Abstract
Background
Momordica charantia is a member of the Cucurbitaceae family and has traditionally been used for medical nutritional therapy to cure diabetes, and its various biological properties have been reported. However, several studies have demonstrated that M. charantia may exert toxic or adverse effects under different conditions. In this study, we prepared an M. charantia extract using ultrasound-assisted extraction, which is a green technology, and verified its anti-inflammatory effects.
Objectives
The aim of this study was to investigate the anti-inflammatory effects of M. charantia extract using ultrasound-assisted extraction in LPS-induced Raw264.7 macrophages and explore the potential mechanism mediated by the MAPK/NF-κB signaling pathway.
Results
We found that the M. charantia extract was non-toxic up to a concentration of 500 μg/mL in Raw264.7 cells. We verified that treatment with M. charantia extract significantly reduced the production of nitric oxide and proinflammatory cytokines, including TNF-α, IL-1β, IL-2, and IL-6, in LPS-stimulated RAW264.7 cells. Moreover, the anti-inflammatory cytokine IL-10 was dramatically increased by treatment with the M. charantia extract. In addition, the phosphorylation of the transcription factor NF-κB, which modulates the production of inflammatory proteins, including JNK, ERK, and p38, was reduced by downregulation of the MAPK signaling pathway.
Conclusion
These results indicate that the M. charantia extract collected using an industrial ultrasonic system is non-toxic and has an anti-inflammatory effect through regulation of the NF-κB and MAPK pathways, suggesting that it can act as a therapeutic candidate for the treatment of inflammatory diseases.
