Clostridium butyricum (C. butyricum) is known as a butyrate producer and a regulator of gut health,but whether it exerts beneficial effect as a dietary supplement via modulating the intestinal microbiota remains elusive. This study investigated the impact of C. butyricum on the fecal microbiota composition and their metabolites on d 14 and d 28 after weaned with 10 g/kg dietary supplementation of C. butyricum. Dynamic changes of microbial compositions showed dramatically increasing Selenomonadales and decreasing Clostridiales on d 14 and d 28...

In this work, hydrogen (H2 ) was produced through the fermentation of Spirogyra sp. biomass by Clostridium butyricum DSM 10702. Macronutrient stress was applied to increase the carbohydrate content in Spirogyra, and a 36% (w/w) accumulation of carbohydrates was reached by nitrogen depletion. The use of wet microalga as fermentable substrate was compared with physically and chemically treated biomass for increased carbohydrate solubilisation. The combination of drying, bead beating and mild acid hydrolysis produced a saccharification yield of 90...

Lignocellulosic biomass as co-substrate enhances the 1,3-propanediol (1,3-PD) production of anaerobic fermenters by increasing their conversion yield from glycerol. To improve 1,3-propanediol (1,3-PD) production by this efficient approach, Clostridium butyricum I5-42 was supplemented with lignocellulosic biomasses (starch free fiber (CPF) from cassava pulp and xylan) as co-substrates. The 1,3-PD production and growth of C. butyricum were considerably higher in glycerol plus CPF and xylan than in glycerol alone, whereas another major polysaccharide (cellulose co-substrate) failed to improve the 1,3-PD production...

Most Group I Clostridium botulinum strains harbor botulinum neurotoxin (bont) genes on their chromosome, while some carry these genes (including bont/a, bont/b, and bont/f) on large plasmids. Prior work in our laboratory demonstrated that Group I BoNT plasmids were mobilized to C. botulinum recipient strains containing the Tn916 transposon. Here, we show that Tn916 is nonessential for plasmid transfer. Relying on an auxotrophic donor phenotype and a plasmid-borne selectable marker, we observed the transfer of pCLJ, a 270 kb plasmid harboring two bont genes, from its host strain to various clostridia...

Salmonella enterica serovar Typhimurium continues to be a major cause of foodborne illness worldwide and pork can serve as a source of infection. Co-infection of S. enterica with Lawsonia intracellularis, a common intestinal pathogen of swine, has been found as risk factor for increased S. enterica shedding. The objective of this study was to investigate if vaccination against L. intracellularis could lead to decreased S. Typhimurium shedding. To test this hypothesis, pigs were challenged with either S. Typhimurium or S...

The prebiotic effects of GOS (galactooligosaccharides) are known to depend on the glycosidic linkages, degree of polymerization (DP), and the monosaccharide composition. In this study, a novel form of α-GOS with a potentially improved prebiotic effect was synthesized using bifidobacterial α-galactosidase (α-Gal) purified from recombinant Escherichia coli. The carbohydrate produced was identified as α-d-galactopyranosyl-(1→6)-O-α-d-glucopyranosyl-(1→2)-[α-d-galactopyranosyl-(1→6)-O-β-d-fructofuranoside] and was termed stachyobifiose...

Visceral hypersensitivity induced by stress is quite common in irritable bowel syndrome (IBS) patients. Probiotics play an important role in reducing visceral hypersensitivity in IBS patients. However, the mechanism has not been clearly elucidated. In this study, we investigated the role of nod-like receptor pyrin domain-containing protein 6 (NLRP6) in Clostridium butyricum-regulated IBS induced by stress. Our results showed that NLRP6 was down-regulated in IBS group colon tissues. In addition, IL-18, IL-1β, myeloperoxidase (MPO), d-lactic acid (D-LA), and CD172a were up-regulated in the IBS group of colonic mucous...

Although 14-day triple therapy has been widely administrated for eradicating Helicobacter pylori (H. pylori) in Asia, its antibiotic-associated side effects restrict the effectivity of eradication therapy in pediatric patients. Therefore, a network meta-analysis (NMA) was conducted to compare the efficacy and safety of probiotics supplemented in 14-day triple therapy in Asian pediatric patients. Materials and Methods: Randomized controlled trials (RCTs) were retrieved comprehensively in electronic databases (such as PubMed, Cochrane library, Embase, CNKI, Wan fang database, VIP database and CBM) until April 2017...
