Abstract
Dioscorea opposite waste (DOW) has been shown to improve the gastrointestinal microbiome, antioxidation capacity, and immune activity, indicating it is a potential feed resource to improve the physiological health and rumen function of weaned lambs. In the present study, the responses of rumen microbiome to DOW supplementation in diet were profiled using metagenome sequencing. In addition, the potential of DOW to regulate plasma parameters in weaned lambs and its possible mechanisms were investigated. Sixty healthy male small tail Han lambs (22.68 ± 2.56 kg) were selected and equally assigned to four dietary treatments: (1) DOW-free diet (CON), (2) addition of 10% DOW diet (DOW1), (3) addition of 15% DOW diet (DOW2), and (4) addition of 20% DOW diet (DOW3). Experimental lambs were fed a corresponding diet for 62 days. Rumen microbiome and plasma parameters were determined at the end of the experiment. The results showed that dietary supplementation with DOW linearly increased the concentration of aspartate aminotransferase, alkaline phosphatase, Immunoglobulin A, Immunoglobulin M, Immunoglobulin G, Glutathione peroxidase, Superoxide dismutase, and total antioxidant capacity in the plasma of weaned lambs, but an opposite trend was observed in Interleukin-1β, Interleukin-6, tumor necrosis factor-α, and Malondialdehyde between the DOW-supplemented group and the CON group. Sequencing of rumen metagenome revealed that dietary supplementation with 20% DOW significantly affected the microbial composition and function and increased the richness and diversity of rumen microbiota and relative abundance of phylum Verrucomicrobia, Planctomycetes, Fibrobacteres, Chloroflexi, Actinobacteria, and Acidobacteria and species Ruminococcaceae_bacterium, Clostridiales_bacterium_NK3B98, Clostridiales_bacterium, and Clostridia_bacterium. It was concluded that supplementing the weaned lamb’s ration with DOW increased the immune response and antioxidant capacity in a dose-dependent manner. Meanwhile, dietary supplementation with 20% DOW modulated the composition of rumen microbiome function by increasing Ruminococcaceae_bacterium and Clostridiales_bacterium with improving the polysaccharide hydrolase activity in the rumen.

Domestic Cooking Affects the Prebiotic Performances of Chinese Yam. Foods 2022; 11:foods11233794. [PMID: 36496601 PMCID: PMC9739818 DOI: 10.3390/foods11233794] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 11/14/2022] [Accepted: 11/21/2022] [Indexed: 11/27/2022] Open
Abstract
The appropriate domestic cooking methods can retain and protect the biological properties of foods well. Thus, the objective of this study was to unravel the effect of different cooking methods on the microbiota modulatory properties of yam and their non-starch polysaccharides by an in vitro simulated digestion and fermentation model. The results showed that different cooking processes led to different changes in polysaccharide content. The polysaccharide content of yam increased by 21.3~108.2% or decreased by 12.0% compared with that of raw yam. Additionally, the soluble polysaccharides contents in all cooked yam samples significantly increased by 16.85~119.97% after in vitro digestion. The regulation of whole-yam digesta on gut microbiota was partly related with yam polysaccharides. Both yam and yam polysaccharide fermentation appeared to promote beneficial bacteria, such as Bifidobacteria, Bacteroides spp. and Megasphaera and suppressed bacterial pathogens such as Ruminococcusforques and Escherichia-Shigella. Household cooking significantly influenced the prebiotic performances of yam and yam polysaccharides by changing the heat-sensitive microbial substrates and their physiology properties. According to our results, normal-pressure steaming and normal-pressure boiling processes can retain the microbiota modulatory effects of Chinese yam.

Plant Polysaccharides Modulate Immune Function via the Gut Microbiome and May Have Potential in COVID-19 Therapy. MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27092773. [PMID: 35566123 PMCID: PMC9101721 DOI: 10.3390/molecules27092773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Revised: 04/17/2022] [Accepted: 04/18/2022] [Indexed: 11/24/2022]
Abstract
Plant polysaccharides can increase the number and variety of beneficial bacteria in the gut and produce a variety of active substances, including short-chain fatty acids (SCFAs). Gut microbes and their specific metabolites have the effects of promoting anti-inflammatory activity, enhancing the intestinal barrier, and activating and regulating immune cells, which are beneficial for improving immunity. A strong immune system reduces inflammation caused by external viruses and other pathogens. Coronavirus disease 2019 (COVID-19) is still spreading globally, and patients with COVID-19 often have intestinal disease and weakened immune systems. This article mainly evaluates how polysaccharides in plants can improve the immune system barrier by improving the intestinal microecological balance, which may have potential in the prevention and treatment of COVID-19.

Maternal Supplementation With Different Probiotic Mixture From Late Pregnancy to Day 21 Postpartum: Consequences for Litter Size, Plasma and Colostrum Parameters, and Fecal Microbiota and Metabolites in Sows. Front Vet Sci 2022; 9:726276. [PMID: 35211537 PMCID: PMC8860973 DOI: 10.3389/fvets.2022.726276] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Accepted: 01/17/2022] [Indexed: 11/13/2022] Open
Abstract
The present study determined the effects of different probiotic mixture supplementation to sows from late pregnancy to day 21 postpartum on reproductive performance, colostrum composition, plasma biochemical parameters, and fecal microbiota and metabolites. A total of 80 pregnant sows were randomly assigned to one of four groups (20 sows per group). The sows in the control group (CON group) were fed a basal diet, and those in the BS-A+B, BS-A+BL, and BS-B+BL groups were fed basal diets supplemented with 250 g/t of different probiotic mixture containing either 125 g/t of Bacillus subtilis A (BS-A), Bacillus subtilis B (BS-B), and/or Bacillus licheniformis (BL), respectively. The trial period was from day 85 of pregnancy to day 21 postpartum. The results showed that different dietary probiotic mixture supplementation increased (P < 0.05) the average weaning weight and average daily gain of piglets, while dietary BS-A+BL supplementation increased the number of weaned piglets (P < 0.05), litter weight (P = 0.06), litter weight gain (P = 0.06), and litter daily gain (P = 0.06) at weaning compared with the CON group. Different dietary probiotic mixture supplementation improved (P < 0.05) the colostrum quality by increasing the fat and dry matter concentrations, as well as the protein and urea nitrogen concentrations in the BS-A+BL group. Dietary probiotic mixture BS-B+BL increased the plasma total protein on days 1 and 21 postpartum while decreased the plasma albumin on day 1 postpartum (P < 0.05). In addition, the plasma high-density lipoprotein-cholesterol was increased in the BS-A+B and BS-B+BL groups on day 21 postpartum, while plasma ammonia was decreased in the BS-A+B and BS-A+BL groups on day 1 and in the three probiotic mixtures groups on day 21 postpartum (P < 0.05). Dietary supplementation with different probiotic mixture also modified the fecal microbiota composition and metabolic activity in sows during pregnancy and postpartum stages. Collectively, these findings suggest that maternal supplementation with Bacillus subtilis in combination with Bacillus licheniformis are promising strategies for improving the reproductive performance and the overall health indicators in sows, as well as the growth of their offspring.

Abstract
This study aims to determine the effect of polysaccharides extracted from Enteromorpha intestinalis (EI) on the intestinal function of Sprague Dawley (SD) rats. The polysaccharides were extracted from the green alga using water and alkaline solution, where these extracts were named WPEI and APEI, respectively. The dried powder of EI was labeled as DPEI. Proximate compositions, minerals, and amino acids of the DPEI, WPEI, and APEI were determined. The growth-promoting effect of the polysaccharides on selected intestinal microflora was determined based on the plate count method. In contrast, the in vivo effect of DPEI and its polysaccharides on the intestinal function of the SD rats was determined. These rats were fed with 1% WPEI, APEI, and DPEI. The result showed that APEI had lower total sugars and total proteins content than the WPEI. WPEI did not contain arabinose. The WPEI and APEI also had a better ability to promote microbial growth than the DPEI. The in vivo study showed that WPEI improved intestinal peristalsis and other intestinal functions compared with the other rat groups. The average final body weight of the experimental rats treated with DPEI was also lower than the other groups. The pH value of the feces of all treated rats was lower than the control rats, and the moisture content of the fecal samples of these experimental groups was higher than the control group. Also, the intestinal activated carbon propulsion of the WPEI, APEI, and DPEI fed rats increased. Among the short-chain fatty acids content determined in the fecal samples, the propionic acid content of the WPEI group was significantly highest. Therefore, WPEI had the best effect in improving intestinal digestion.

Abstract
Plant extracts were considered as natural resources to alleviate weaning stress in pig production. A 28-day study (Phase 1: d 0-14 and Phase 2: d 15-28) was conducted to investigate the effects of compound of hawthorn and yam extracts on growth performance, intestinal health, and immune function in weaned pigs. A total of 144 weaned pigs with average body weight (BW) of 7.89 ± 1.09 kg were assigned to three treatments with six replicates pens by BW and sex. Dietary treatments included negative control (NC), corn-soybean meal basal diet; positive control (PC), NC + 0.08% enzyme preparations and 0.3% acidifiers; and CHY, NC + 0.3% compound of hawthorn and yam extracts. Compared with NC-fed pigs, pigs fed CHY had greater (p < 0.05) growth performance in Phase 1. The CHY-fed pigs had greater (p < 0.05) activities of duodenal lipase, trypsin, and greater (p < 0.05) serum concentrations of total antioxidant capacity and glutathione peroxidase. The CHY-fed pigs had improved (p < 0.05) jejunal morphology and greater (p < 0.05) ileac valeric acid and colonic propionic acid, isobutyric acid concentrations than NC- and PC-fed pigs. In conclusion, CHY can improve growth performance and is a promising additive in weaned pig diets.

Abstract
The human digestive tract is the cottage to trillions of live microorganisms, which regulate health and illness. A healthy Gut Microbiota (GM) is necessary for preventing microbial growth, body growth, obesity, cancer, diabetes, and enhancing immunity. The equilibrium in GM's composition and the presence/absence of critical species enable specific responses to be essential for the host's better health condition. Research evidences revealed that the dietary plants and their bioactive phytochemicals (BPs) play an extensive and critical role in shaping the GM to get beneficial health effects. BPs are also known to improve gastrointestinal health and reduce the risk of several diseases by modulating GM-mediated cellular and molecular processes. Regular intake of BPs-rich vegetables, fruits, and herbal preparations promotes probiotic bacteria, including Bifidobacteria and Lactobacillus species, while inhibiting unwanted gut residents' development Escherichia coli, and Salmonella typhimurium etc. Upon consumption, BPs contact the GM that gets transformed before being absorbed from the gastrointestinal tract. Biotransformation of BPs by GM is linked with the enhancement of bioactivity/toxicity diminishment of the BPs compared to parental phytochemicals. Therefore, the current review focuses on the role of BPs in shaping GM for the prevention and treatment of human diseases.

Abstract
Sixteen 35-day-old piglets, including eight Large White (LW) piglets (a lean-type pig breed) and eight Ningxiang (NX) piglets (a fatty-type Chinese Indigenous pig breed), were fed the same diet for 105 days. NX pigs had higher intramuscular fat content than LW pigs (p < 0.05). According to 16S rRNA gene sequencing, the relative abundances of the genera Ruminococcaceae_NK4A214_group, Parabacteroides, Christensenellaaceae_R-7_group and Ruminiclostridium were higher, whereas the abundances of Prevotellaceae_NK3B31_group, Prevotella, Subdoligranulum and Faecalibacterium were lower, in the colon of NX pigs compared to that of LW pigs. Nonmetric multidimensional scaling analysis revealed that the microbiota of the two pig breeds clustered separately along the principal coordinate axis. Furthermore, functional prediction of the bacterial communities suggested higher fatty acid biosynthesis in NX pigs. NX pigs also exhibited lower concentrations of total short-chain fatty acids, propionate and butyrate in the colon (p < 0.05). These findings suggest that NX pigs exhibited higher intramuscular fat content and backfat thickness than LW pigs. The bacterial communities in the colon of NX pigs were also more diverse than those in the colon of LW pigs, which might be used as a potential metabolomics mechanism to research different breeds of pigs.

Abstract
The new coronavirus pneumonia, named COVID-19 by the World Health Organization, has become a pandemic. It is highly pathogenic and reproduces quickly. There are currently no specific drugs to prevent the reproduction and spread of COVID-19. Some traditional Chinese medicines, especially the Lung Cleansing and Detoxifying Decoction (Qing Fei Pai Du Tang), have shown therapeutic effects on mild and ordinary COVID-19 patients. Polysaccharides are important ingredients in this decoction. This review summarizes the potential pharmacological activities of polysaccharides isolated by hot water extraction from Lung Cleansing and Detoxifying Decoction, which is consistent with its production method, to provide the theoretical basis for ongoing research on its application.

Abstract
A diverse range of symbiotic gut bacteria codevelops with the host and is considered a metabolic "organ" that not only facilitates harvesting of nutrients from the dietary components but also produces a class of metabolites. Many metabolites of gut microbes have an important impact on host health. For example, an inventory of metabolic intermediates derived from bacterial protein fermentation may affect host physiology and pathophysiology. Additionally, gut microbiota can convert cholesterol to bile acids and further into secondary bile acids which can conversely modulate microbial community. Moreover, new research identifies that microbes synthesize vitamins for us in the colon. Here, we will review data implicating a major class of bacterial metabolites through breaking down dietary fiber we cannot process, short-chain fatty acids (SCFAs), as crucial executors of alteration of immune mechanisms, regulation of metabolic homeostasis, and neuroprotective effects to combat disease and improve health.

Abstract
The Chinese yam peel (CYP) is a by-product of yam processing that is rich in various nutrients and a good source for feed additives. This study investigated the effects of CYP on the intestinal microbiota and gut defence barrier of the common carp (Cyprinus carpio L.). Different groups of experimental fish were fed a normal control diet (NC), a low CYP diet (LYP) and a high CYP diet (HYP) for 8 weeks. After the feeding trial, the fish were assessed for intestinal enzyme activity, intestinal histology, immune-related gene expression, intestinal SCFAs and intestinal microbiota. Our results indicated that the intestinal integrity and antioxidant enzyme (CAT and SOD) activity in the common carp were enhanced following CYP supplementation. The mRNA levels of anti-inflammatory (TGF-β), tight binding protein (occludin and ZO-1) and pathway factor genes (TLR4 and NF-κB) were significantly upregulated in the HYP group (P<0.05), which was accompanied by an increase in the level of pro-inflammatory IL-1β in the gut (P<0.05). High-throughput sequencing revealed that Fusobacteria, Proteobacteria, and Bacteroidetes bacteria were most abundant in the microbial community in the gut of the common carp. The relative abundances of Bacteroides, Flavobacterium and Lactobacillus were increased, while the abundances of pathogenic microorganisms such as Enterobacteriaceae, Shewanella, Pseudomonas and Vibrio were reduced after treatment with CYP. Furthermore, the concentrations of acetic acid, propionic acid, butyric acid and total short-chain fatty acids (SCFAs) in the gut were also increased (P<0.05). Finally, our results revealed correlations between gut microbiota, SCFAs, non-specific immunity and antioxidant enzymes in CYP-fed carp. These results suggest that CYP-supplemented feed could improve the immunity of the common carp by modulating the intestinal microflora and enhancing the gut defence barrier and has the potential to be used as an immunostimulating feed additive in aquaculture.

Abstract
BACKGROUND AND AIM Inflammatory bowel disease results from a dysregulated immune response to intestinal microbial flora in individuals with genetic predisposition(s). This study aimed to determine the effects of compound polysaccharides (CP) containing yam polysaccharide and inulin on the rat model of colitis induced by 2,4,6-trinitrobenzenesulfonic acid (TNBS) and to explain the mechanism in terms of gut microbiota composition and function. METHODS Male SD rats were divided into three groups: the control group, the model group, and the CP group. Disease activity index, serum myeloperoxidase level, and the composition and function of gut microbiota were analyzed. RESULTS The data in the study showed CP reduced inflammation in the rat model of colitis induced by TNBS and ameliorated the experimental colitis. The results also indicated that CP not only reversed TNBS-induced gut dysbiosis-indexed by increased short-chain fatty acids (SCFAs)-producing bacteria, lactic acid-producing bacteria, and decreased Bacteroides, Proteobacteria as well as sulfate-reducing bacteria, but also restored the dysregulated microbiota function of colitic rats into a normal condition, including an improvement on basic metabolism and a reduction on oxidative stress, cell motility, signal transduction, xenobiotics biodegradation, and metabolism as well as pathogenesis processes. CONCLUSIONS Compound polysaccharides ameliorated the experimental colitis of rats induced by TNBS by modulating the gut microbiota composition and function profiles, which makes it possible to be used as prebiotic agents to treat gut dysbiosis in colitis individuals.

Abstract
Antibiotic-associated diarrhea (AAD) is a common adverse effect of antibiotic treatment. The study was to evaluate effects of Chinese yam (Dioscorea opposita Thunb.) on AAD, and changes of intestinal microbiota and short-chain fatty acids (SCFA). AAD model was established using Balb/c mice by gavage with ampicillin for 5 days, followed by a 10-day administration of low, medium, and high dosage of Chinese yam, containing allantoin (4.35 mg/g) and polysaccharides (85.51 mg/g). The results showed that Chinese yam accelerated the recovery from acute diarrhea, reverse AAD-induced body weight loss and cecal enlargement. The high-dosage Chinese yam increased probiotic Bifidobacteria and Lactobacilli by 47% and 21% and decreased potential pathogen Enterococcus and Clostridium perfringens by 8% and 27% on day 15 (P < .05). Bacterial community analysis revealed that Chinese yam contributed to repair the ampicillin-induced intestinal microbiota disorder, enrich the abundance of Bacteroides spp. and Clostridium spp. Additionally, Chinese yam supplementation increased the production of SCFA.

Abstract
With the increase in evidences directly linking diet and health, several foodstuffs, such as phenolic rich fruits and vegetables, have emerged as possessing potential health benefits. Plants, given their fiber and phenolic content (and their intrinsic biological potential), have long been considered as contributing to health promotion. Therefore, the present work aimed to review the existing evidences regarding the various potential benefits of plant extracts' and plant extract-based products' consumption, with emphasis on in vivo works and epidemiological studies whenever available. Overall, the information available supports that, while there are indications of the potential benefits of plant extracts' consumption, further human-based studies are still needed to establish a true cause-effect.

Abstract
As an important source for traditional medical systems such as Ayurvedic medicine and traditional Chinese medicine, herbal medicines have received widespread attentions from all over the world, especially in developing countries. Over the past decade, studies on gut microbiota have generated rich information for understanding how gut microbiota shape the functioning of our body system. In view of the importance of gut microbiota, the researchers engaged in studying herbal medicines have paid more and more attention to gut microbiota and gut microbiota metabolites. Among a variety of gut microbiota metabolites, short-chain fatty acids (SCFAs) have received most attention because of their important role in maintaining the hemostasis of hosts and recovery of diseases. Herbal medicines, as an important resource provider for production of SCFAs, have been demonstrated to be able to modulate gut microbiota composition and regulate SCFAs production. In this mini-review, we summarize current knowledge about SCFAs origination, the role of SCFAs in health and disease, the influence of herbal medicine on SCFAs production and the corresponding mechanisms. At the end of this review, the strategies and suggestions for further research of SCFAs and herbal medicines are also discussed.

Abstract
This study was conducted to investigate the effects of dietary supplementation with Sangrovit® (SAG; minimum of 1.5% sanguinarine, a quaternary benzo[c]phenanthridine alkaloid extracted from Macleaya cordata) on growth performance, intestinal morphology, intestinal microflora and its metabolites of early-weaned piglets. A total of 20 healthy weaned piglets (Duroc× [Large White×Landrace]), weaned at 21 days of age with an average body weight (BW) of 6.52 ± 0.23 kg, were randomly assigned to receive either a corn-soybean meal basal diet (CTR) or a basal diet supplemented with 50 mg/kg SAG (SAG). During the 21-days trial, we collected and analysed intestinal tissues and the luminal digesta for their morphology and populations of gut microbiota, as well as for measuring the concentrations of short-chain fatty acids (SCFAs) and ammonia. Compared with the CTR group, supplementation with SAG improved average daily gains (p = 0.011) and average daily feed intake (p = 0.037). Piglets fed the SAG diet had an average lower value for crypt depth of the jejunum (p = 0.011) and greater values for villus height in the ileum (p = 0.015) and ratios of villus height to crypt depth in the jejunum (p < 0.01) and in the ileum (p = 0.027) than did animals receiving the CTR diet. The addition of SAG increased the amounts of Lactobacillus in the ileum (p = 0.033) and caecum (p < 0.01), and tended to increase the amounts of Bifidobacterium (p = 0.058) in the caecum, while decreasing the amounts of Escherichia coli (p = 0.046) and Salmonella spp. (p = 0.035) in the ileum, as well as Salmonella spp. (p = 0.029) in the caecum. Dietary supplementation with SAG enhanced (p < 0.05) the concentrations of acetate, propionate, butyrate and total SCFAs, and also tended to increase the level of valerate (p = 0.055 and p = 0.052) in the ileal and caecal contents when compared with the CTR group. Concentrations of ammonia also declined in the caecal (p = 0.037) and ileal (p = 0.046) digesta in response to SAG. These results indicate that feeding early-weaned piglets a SAG-supplemented diet can potentially improve their growth performance and intestinal morphology, and can modify the intestinal luminal environment in a beneficial manner.

Absorption of Codonopsis pilosula Saponins by Coexisting Polysaccharides Alleviates Gut Microbial Dysbiosis with Dextran Sulfate Sodium-Induced Colitis in Model Mice. BIOMED RESEARCH INTERNATIONAL 2018; 2018:1781036. [PMID: 30211217 PMCID: PMC6120299 DOI: 10.1155/2018/1781036] [Citation(s) in RCA: 55] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/12/2018] [Revised: 06/22/2018] [Accepted: 07/05/2018] [Indexed: 12/16/2022]
Abstract
Objectives Inflammatory Bowel Disease (IBD) is an autoimmune disease, and the gut microbiota has become a new therapeutic target. Herbal medicine (HM) has shown good efficacy in the clinical treatment of IBD; however, the synergistic actions of the dominant chemicals in HM decoctions are unclear. Methods In this study, we explored whether the complicated interconnections between HM and the gut microbiota could allow crosstalk between HM ingredients. Saponins and polysaccharides, i.e., the dominant chemicals in the Codonopsis pilosula Nannf (CPN) decoction, were investigated in a dextran sulfate sodium- (DSS-) induced mouse model. Bacterial 16S rRNA sequencing analyzed the change of gut microbiota structure and diversity. Gas chromatography (GC) determined the content of short-chain fatty acids (SCFAs) in feces. ELISA detected the expression of proinflammatory and anti-inflammatory cytokines associated with TH17/Treg balance. UPLC-QTOF-MS technology combined with PKsolver software analyzed the absorption of the highest exposure for monomeric compounds of CPN saponins in serum. The results indicated that CPN polysaccharides showed prebiotic-like effects in mice with DSS-induced colitis by simultaneously stimulating the growth of three important probiotics, i.e., Bifidobacterium spp., Lactobacillus spp., and Akkermansia spp., and inhibiting the growth of pathogenic bacteria, including Desulfovibrio spp., Alistipes spp., and Helicobacter spp. Moreover, CPN polysaccharides improved intestinal metabolism, enhanced the production of short-chain fatty acids, upregulated the expression of anti-inflammatory cytokines and downregulated the secretion of proinflammatory cytokines correlated with Th17/Treg balance, promoted the absorption of certain CPN saponins in the serum, and stimulated recovery of the holistic gut microbiota. Conclusion CPN polysaccharides have the good prebiotic properties and shown good application prospects in the prevention and treatment of acute colitis. These findings provide insights into the specific bacteria responsible for active, inactive biotransformation of HM ingredients and those that are altered by HM administration.

Abstract
Alpha-ketoglutarate (AKG), a critical molecule in the tricarboxylic acid cycle, is beneficial to intestinal functions. However, its influence on intestinal microbiota and metabolism is not fully understood. We investigated the effects of a low-protein (LP) diet supplemented with AKG on cecal microbial communities and the parameters of microbial metabolism in growing pigs. Twenty-seven young pigs (Large White × Landrace) with an average initial body weight of 11.96 ± 0.18 kg were randomly allotted into three groups (n = 9): a normal protein (NP) diet containing 20% crude protein (CP); LP diet formulated with 17% CP (LP diet); or LP diet supplemented with 10 g kg-1 of AKG (ALP diet). After a 35-day trial period, the digesta of the cecum were collected to analyze the concentrations of ammonia and short-chain fatty acids (SCFAs). We also performed a microbial analysis. Although no significant differences were found in performance among the diet groups, pigs fed the ALP diet had greater average daily gain (ADG) when compared with those in the LP group. Experimental diet did not affect cecal bacterial richness or diversity, as determined by Chao1 and ACE species richness measures and Shannon and Simpson indices, respectively. The predominant phyla Firmicutes, Bacteroidetes, and Proteobacteria increased in relative abundances in the cecum of pigs fed ALP diet. At the genus level, compared to the LP diet, the ALP diet significantly increased the abundances of Lachnospiraceae UCG-005, Lachnospiraceae NK4A136 group, Phascolarctobacterium and Parabacteroides, while decreased Vibrio and Maritalea. Pigs fed the ALP diet increased Oribacterium and Lachnoclostridium when compared with the NP diet. Non-metric multidimensional scaling analysis revealed that the distribution of microbiota at each group was distinctly clustered separately along principal coordinate. In addition, quantitative PCR revealed that the ALP diet was also associated with increases in the amounts of Bacteroides, Bifidobacterium, and Lactobacillus, but a decrease in the level of Escherichia coli. Compared with the NP diet, the ALP diet enhanced the concentrations of valerate and propionate. This ALP diet also increased the concentrations of valerate and isobutyrate when compared with the LP diet. Moreover, the ALP diet was linked with a significant decline in the concentration of ammonia in the cecum. These results indicate that a LP diet supplemented with AKG can alter the balance in microbial communities, increasing the population of SCFA-producing bacteria and the amounts of Bacteroides and Bifidobacterium, while reducing the counts of Escherichia coli and the amount of ammonia in the cecum.

Abstract
Digestion and fermentation in vitro of polysaccharides from bee collected pollen of Chinese wolfberry (WBPPS) were investigated in the present study. It was found that WBPPS mainly consisted of mannose, ribose, rhamnose, galacturonic acid, glucose, galactose, xylose, and arabinose in a molar ratio of 0.38:0.09:0.17:0.64:0.22:0.67:0.08:1.03, respectively. WBPPS was not affected by human saliva. The fraction A (molecular weight 1340 kDa) of WBPPS was not broken down in simulated gastric and small intestinal juices, while the small fraction B (molecular weight 523 kDa) of WBPPS was degraded. Moreover, fermentation in vitro revealed that WBPPS could significantly enhance the production of short-chain fatty acids and modulate gut microbiota composition via increasing the relative abundances of genera Prevotella, Dialister, Megamonas, Faecalibacterium, and Alloprevotella and decreasing the numbers of genera Bacteroides, Clostridium XlVa, Parabacteroides, Escherichia/Shigella, Phascolarctobacterium, Parasutterella, Clostridium sensu stricto, and Fusobacterium.

Abstract
Herbal medicines (HMs) are much appreciated for their significant contribution to human survival and reproduction by remedial and prophylactic management of diseases. Defining the scientific basis of HMs will substantiate their value and promote their modernization. Ever-increasing evidence suggests that gut microbiota plays a crucial role in HM therapy by complicated interplay with HM components. This interplay includes such activities as: gut microbiota biotransforming HM chemicals into metabolites that harbor different bioavailability and bioactivity/toxicity from their precursors; HM chemicals improving the composition of gut microbiota, consequently ameliorating its dysfunction as well as associated pathological conditions; and gut microbiota mediating the interactions (synergistic and antagonistic) between the multiple chemicals in HMs. More advanced experimental designs are recommended for future study, such as overall chemical characterization of gut microbiota-metabolized HMs, direct microbial analysis of HM-targeted gut microbiota, and precise gut microbiota research model development. The outcomes of such research can further elucidate the interactions between HMs and gut microbiota, thereby opening a new window for defining the scientific basis of HMs and for guiding HM-based drug discovery.

Dietary supplementation with soybean oligosaccharides increases short-chain fatty acids but decreases protein-derived catabolites in the intestinal luminal content of weaned Huanjiang mini-piglets. Nutr Res 2014; 34:780-8. [PMID: 25236424 DOI: 10.1016/j.nutres.2014.08.008] [Citation(s) in RCA: 56] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2014] [Revised: 08/14/2014] [Accepted: 08/22/2014] [Indexed: 01/14/2023]
Abstract
The improvement of gut health and function with prebiotic supplements after weaning is an active area of research in pig nutrition. The present study was conducted to test the working hypothesis that medium-term dietary supplementation with soybean oligosaccharides (SBOS) can affect the gut ecosystem in terms of microbiota composition, luminal bacterial short-chain fatty acid and ammonia concentrations, and intestinal expression of genes related to intestinal immunity and barrier function. Ten Huanjiang mini-piglets, weaned at 21 days of age, were randomly assigned to 2 groups. Each group received a standard diet containing either dietary supplementation with 0.5% corn starch (control group) or 0.5% SBOS (experimental group). The results showed that dietary supplementation with SBOS increased the diversity of intestinal microflora and elevated (P < .05) the numbers of some presumably beneficial intestinal bacteria (e.g., Bifidobacterium sp, Faecalibacterium prausnitzii, Fusobacterium prausnitzii, and Roseburia). Soybean oligosaccharide supplementation also increased the concentration of short-chain fatty acid in the intestinal lumen, and it reduced (P < .05) the numbers of bacteria with pathogenic potential (e.g., Escherichia coli, Clostridium, and Streptococcus) and the concentration of several protein-derived catabolites (e.g., isobutyrate, isovalerate, and ammonia). In addition, SBOS supplementation increased (P < .05) expression of zonula occludens 1 messenger RNA, and it decreased (P < .05) expression of tumor necrosis factor α, interleukin 1β, and interleukin 8 messenger RNA in the ileum and colon. These findings suggest that SBOS supplementation modifies the intestinal ecosystem in weaned Huanjiang mini-piglets and has potentially beneficial effects on the gut.

Abstract
This study was conducted to the determine fermentation characteristics of soybean oligosaccharides (SBOS) in an in vitro system. Digesta collected from the colon of Huanjiang mini-pigs was used as inoculums, and SBOS (0.2 g per 10 mL fermentation broth) was used as substrate during the in vitro fermentation. The inoculum or inoculum + glucose (0.2 g) was used as negative or positive control, respectively. The slurry was fermented in an anaerobic chamber and gas production (GP) recording was taken after 48 h of incubation by referring to the moving scale on the plunger of the glass syringes, and then GP parameters, pH value, NH(3)-N content, short chain fatty acid (SCFA) levels, and microbial community in the fermentation broth were determined. For gas production parameters, pH, and fermentation product determination after 1, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 28, 32, 36, 42, and 48 h of incubation, SBOS and glucose demonstrated similar responses compared to control including increase maximal gas production, decreased lag time, decreased pH, and accumulation of NH(3) and increased SCFA. The exception was rate of GP, which was higher (P < 0.05) for SBOS compared with glucose. Incubation with SBOS increased (P < 0.05) the microbial diversity and population of Bifidobacterium and Lactobacillus but decreased (P < 0.05) Escherichia and Streptococcus when compared with incubation with glucose. These findings suggested that the SBOS can improve the gut microbiota balance in colon and modulate its metabolism.
