  • Purpose: We aimed to investigate the effect of oral Saccharomyces cerevisiae Hansen CBS 5926 therapy (Saccharomyces boulardii) on gastrointestinal symptoms and nutrition in gastrectomized patients. Materials and Methods: Ninety patients who underwent a gastrectomy due to early gastric cancer were randomly divided into case and control (placebo) groups and were given medicine or placebos for 12 weeks. The gastrointestinal symptom rating and the nutritional status were evaluated by using double blind methods at 4, 16, and 20 weeks after discharge. Results: The ratio of males to females was 2.3 : 1, and the mean age was $56.3{\pm}10.2$ years. The numbers of subtotal gastrectomies and total gastrectomies were 69 and 21, respectively. Fourteen (15.6%) patients dropped, of whom 5 belonged to the case group. Of the remaining 76 patients, those in the case group had higher levels of serum albumin (P=0.046). For patients who underwent subtotal gastrectomy (n=57), the case group had higher level of serum albumin (P=0.049). Conclusion: This double blind study showed that oral Saccharomyces boulardii therapy could improve the postoperative nutrition of gastrectomized patients because gastrectomized patients with oral Saccharomyces boulardii therapy had higher levels of serum albumin than the control group.

  • We studied the effects of Saccharomyces cerevisiae boulardii CNCM I-1079 (LSB) supplemented to lactating sows on reproductive traits and farrowing duration and to piglets from day 7 of life on post-weaning performance and IgG concentration. Ninety-six Landrace × Yorkshire sows started the trial 5 days before the expected farrowing date. Sows were distributed into 2 groups according to parity number and backfat thickness: control (CON: regular lactation diet) and LSB (CON + LSB at 2 × 109 colony forming units [CFU]/kg of feed). Seven days after birth, litters were randomly selected from each group and supplemented creep feed with or without LSB at 2 × 109 CFU/kg. At weaning, piglets from CON sows were shifted to a commercial farm and allocated to 14 pens in groups of 25 piglets/pen according to the creep feed supplemented during lactation. Piglets followed a 3-phase feeding program: creep, pre-starter and starter, with or without LSB at 2 × 109 CFU/kg LSB in creep and pre-starter, and 1 × 109 CFU/kg LSB in starter. The piglets were vaccinated against classical swine fever on days 41 and 72 of life. One day before each vaccination and at the end of the trial, blood samples were collected from 15 randomly selected piglets per treatment and assessed for total IgG. Supplemented sows with non-supplemented litters displayed the lowest backfat thickness loss during lactation (p < 0.05). The LSB supplementation shortened farrowing duration (p < 0.05) and increased feed intake (p < 0.05) during the first week of lactation. The LSB-fed piglets were heavier at the end of creep (p < 0.05), pre-starter (p < 0.05), and the trial (p < 0.05); grew faster during creep (p < 0.05), starter (p < 0.05), and overall (p < 0.05); and displayed an improved feed conversion ratio during creep (p < 0.05). Total IgG content was higher at days 40 (p < 0.05) and 71 (p < 0.05) in LSB-fed piglets. We conclude that supplementing sows with Saccharomyces cerevisiae boulardii CNCM I-1079 from late gestation until weaning shortens farrowing duration, increases feed intake, and minimizes backfat losses during lactation. When supplemented to piglet diet, post-weaning performance is improved. This improvement observed could be linked to a better immune status, as suggested by the higher IgG.

  • Microbial fermentation is often used to improve the functionality of plant-based food materials. Herein, we investigated changes in the physicochemical and functional properties of cabbage during yeast fermentation to develop new products using fermented cabbage. Among the 8 types of food-grade yeast, both Saccharomyces cerevisiae and Saccharomyces boulardii fermented 10% cabbage powder solution (w/w) the most effectively, leaving no soluble sugars after 12 h of fermentation. In addition, the yeast fermentation of cabbage resulted in functionally positive outcomes in terms of sulforaphane content, antioxidant properties, and anti-inflammatory activity. Specifically, the yeast-fermented cabbages contained about 500% more sulforaphane. The soluble fraction (5 ㎍/ml) of yeast-fermented cabbage had no cytotoxicity in murine RAW 264.7 cells, and the radical-scavenging capacity was equivalent to 1 ㎍/ml of ascorbic acid. Moreover, cabbage fermented with S. boulardii significantly suppressed both lipopolysaccharides (LPS)-induced nitric oxide production and LPS-induced reactive oxygen species production in RAW 264.7 cells, suggesting a potential anti-inflammatory effect. These results support the idea that yeast fermentation is promising for developing functionally improved cabbage products.

  • Probiotics are microorganisms that can benefit host health when ingested in a live state, and lactic acid bacteria are the most common type. Among fungi, Saccharomyces boulardii (SB) is the only strain known to have a probiotic function with beneficial effects on colitis; however, information on other probiotic yeast strains is limited. Therefore, this study aimed to discover yeast strains expressing intestinal anti-inflammatory activities by exhibiting probiotic properties in dextran sodium sulfate (DSS)-induced colitis mice model. Nuruk (Korean traditional fermentation starter) containing various microbial strains was used as a source for yeast strains, and S. cerevisiae 28-7 (SC28-7) strain was selected with in vitro and in vivo characteristics to enable survival in the intestines. After 14 days of pretreatment with the yeast strains, DSS was co-administered for six days to induce colitis in mice. The results revealed that the disease activity index score was lowered by SC28-7 treatment compared to the DSS group, and the colon length and weight/length ratio were recovered in a pattern similar to that of the normal group. SC28-7 administration significantly reduced the secretion of pro-inflammatory cytokines in the serum and modified the mRNA expression of inflammatory cytokines (interleukin-1β, transforming growth factor-β, and interferon-γ) and proteins involved in gut barrier functions (mucin 2, mucin 3, zonula occludens-1, and occludin) in colon tissues. These results indicate that SC28-7 attenuates DSS-induced colon damage and inflammation, supporting its future use as a probiotic yeast for treating and preventing intestinal inflammatory diseases such as inflammatory bowel disease.

  • Forty alcohol yeast strains were isolated from the main mashes (10 strains from each mash) for brewing of 4 different kinds of Korean traditional liquor (3 different types of Yakju and 1 Takju). Thirty-eight out of 40 strains were identified to be the same strain, Saccharomyces boulardii, by the Automated Bacteria, Yeast, and Fungi Identification System (Biolog Co., U.S.A.) based on the metabolic fingerprints. One strain that showed the highest ethanol production among the 38 strains in YPD medium, designated SHY 111, was selected and used for differentiating from other yeast type strains using the polymerase chain reaction (PCR). Amplified DNA, from transcribed internal spacers of SHY 111 chromosomal DNA, was found to be the same in both size and sequence as those of S. cerevisiae KCCM 11215 (formerly S. coreanus) and S. boulardii along with that of S. cerevisiae AB 972, which was used as a type strain for the yeast genome project. However, when PCR was carried out with the intron splice site primer, it resulted in the amplification of the SHY 111-specific DNA fragment which was about 200 bp in size. When PCR was carried out using the primer to test diversity of 40 isolated yeast strains, it was found that the PCR patterns were similar to each other except for the 200 bp bands derived from all the 10 strains from one Yakju, and 2 strains from another Yakju. These results suggest the strain identified as S. boulardii by the Automated Identification System to be a dominant strain for the fermentation of Korean traditional liquors.
