  • Ginseng are native traditional herbs, which exhibit excellent pharmacological activities. Probiotic Lactobacillus helveticus KII13 and Pediococcus pentosaceus strain KID7 were used for ginsenoside transformation by fermenting crude ginseng extract to enhance minor gisenoside content. Thin-layer chromatography (TLC) analysis of fermented ginseng extract showed that the minor ginsenosides Rg3, Rh1, and Rh2 were main products after 5 days of fermentation. HPLC analysis was performed to quantify the major and minor ginsenosides. The Rg3 peak appeared on the 3rd day while the appearance of Rh2 peak and Rh1 peak were observed on the 5th day. The co-culture of L. helveticus KII13 and P. pentosaceus KID7 converted major ginsenosides (Rb1 and Rg1) into minor ginsenosides (Rg3, Rh2, and Rh1).

  • In this study, we identified that the fermentation of Korean indigenous probiotics and red ginseng produced ginsenoside compound K (CK) from major ginsenosides. Based on whole genome sequencing of 19 probiotics species, β-glucosidase, α-arabinofuranosidase, β-xylosidase, and α-rhamnosidase related to bioconversion of ginsenosides are identified in the genome of 19 species, 3 species, 6 species, and 8 species, respectively. Among the 19 probiotics species, Bifidobacterium longum CBT BG7 converted from ginsenoside Rb1 to CK, and both B. breve CBT BR3 and B. lactis CBT BL3 converted ginsenoside Rb1 to Rd. The final concentration and yield of ginsenoside F2 and CK were higher in the fermentation with the nondisrupted cells than with disrupted cells. The combination of both CBT BG7 and BL3, and CBT BG7 and BR3 showed higher amounts of F2 than CBT BG7 only. CBT BG7 with adding α-amylase increased the amounts of F2. In this study, we identified that the fermentation of both Korean indigenous probiotic bacteria CBT BG7, BR3 and BL3, and red gingseng is able to produce CK, a bioactive compound that promotes health benefits.

  • The purpose of this study is to manufacture ice cream with perilla leaves fermented extract(5%, 10%, 15%, and 20% w/v) fermented by Lactobacillus acidophilus KCTC 3164 strain as functional additives. The physical and chemical properties(color, viscosity, pH, total acidity, melting rate, overrun) and antioxidant activity of ice cream with perilla leaves fermented extract were evaluated. The addition of perilla leaves fermented extract affected the color of the ice cream, and the melting rate increased with increasing addition of perilla leaves fermented extract. In contrast, viscosity showed a gradual decrease. Overrun increased gradually with higher levels of perilla leaves fermented extract, while pH decreased significantly, and total acidity increased. The DPPH radical scavenging activity and total polyphenol content of ice cream with perilla leaves fermented extract significantly increased with higher concentrations of fermented perilla leaves extract. The results of this study indicate that the ice cream sample with 10% fermented perilla leaves extract has a potential as a functional ice cream since it exhibited high overrun, a low melting rate, the desired viscosity, and high DPPH radical scavenging activity and total polyphenol content.

  • Health of human intestine has deteriorated due to excessive stress and western diet. In this study, Vigna angularis was fermented by Bacillus subtilis KCCM11965P in order to develop prebiotic resource for improving bowel movement. The contents of ash and crude protein were $3.35{\pm}0.04%$ and $21.1{\pm}0.19%$ respectively. Vigna angularis extract (1, 3, 5%) were incubated with 3% (v/v) Bacillus subtilis KCCM 11965P for 0, 24, 48, and 72 h. Total bacterial numbers showed that the combination of 3% powdered seeds and 72 h incubation time was optimum condition for this experiment. Total polyphenol content increased from $0.18{\pm}0.010mg/mL$ in pre-incubation to $0.23{\pm}0.007mg/mL$ in post-incubation with the condition mentioned above. DPPH radical scavenging activity also increased from $36.1{\pm}6.0%$ to $63.6{\pm}5.2%$. Analysis of protease activity showed $2.69{\pm}0.003unit/mL$ in combination of 5% powdered seeds and 72 h incubation time. Amylase activity increased from $1.0{\pm}0.1unit/mL$ in pre-incubation to $26.0{\pm}0.2unit/mL$ in post-incubation. The analysis of free amino acids after incubation with Bacillus subtilis KCCM 11965P showed that leucine increased from 5.22 mg/L to 67.59 mg/L and tyrosine, one of non-essential amino acid also increased 10.08 mg/L to 259.35 mg/L by incubation with 5% powdered seeds. Most of organic acid were reduced by incubation for 72 h. These results suggest that Vigna angularis could be utilized most as a prebiotic resources.

  • One of the main microorganisms causing diarrheal diseases is Campylobacter jejuni. Purslane or Portulaca oleracea is an edible plant containing polyphenols that has been widely used as a folk remedy for treatment of diarrhea for a long time. This study was performed to investigate the antimicrobial activity of fermented P. oleracea extracts made with probiotics and plant-origin lactic acid bacteria(PLAB) isolated from P. oleracea against C. jejuni. Lactobacillus rhamnosus, L. acidophilus, L. bulgaricus, L. delbrueckii, L. plantarum, Leuconostoc mesenteroides and Bifidobacterium longum were applied to P. oleracea to make a fermentation broth of purslane. Leuconostoc mesenteroides and the lactic acid bacteria isolated from P. oleracea grew best in the fermentation broth of P. oleracea extracts when the broth was combined with 2% yeast extract, 1% peptone, and 0.05 to 1% potassium phosphate. The number of viable cells in the fermentation broth containing purslane extracts after 48 hours increased to $1{\times}10^{12}\;CFU/m{\ell}$ and remained at $1.3{\times}10^{10}\;CFU/m{\ell}$ after refrigeration for 2 weeks. The pH and acidity of purslane-fermented broth after 48 hours of fermentation was 3.7 and 3.14, respectively, which show that the fermentation broth was within the range of the general standards of fermented dairy products. The antimicrobial activity of the fermented P. oleracea extracts was determined using the liquid culture method. The 10 $mg/m{\ell}$ concentration of the fermented P. oleracea extract made with Leuconostoc mesenteroides and the lactic acid bacteria isolated from purslane showed the strongest antimicrobial activity against C. jejuni. The fermentation broth of purslane with the probiotics retarded the growth of C. jejuni for 48 hours at $42^{\circ}C$.

  • This study aimed to provide basic evidence regarding the development of materials by analyzing the physicochemical properties and antioxidant activities of Streptococcus thermophilus KCCM 3782 strain-fermented Cordyceps militaris grown on Tenebrio molitor. Among the solvents tested, DPPH radical scavenging activity was the highest in the hot water-extracted sample after 30 min of extraction. Moisture content decreased, whereas crude protein and fat content increased, after lactic acid bacteria-mediated fermentation. Sodium, magnesium, calcium, and zinc contents increased, with potassium levels attaining the maximum value, whereas free amino acid content decreased after the fermentation. Among Hunter's color values, a value increased to $66.7{\rightarrow}149.92$ after fermentation, whereas the L and b values decreased to $15.79{\rightarrow}-15.75$ and $54.45{\rightarrow}0.01$, respectively. Cordycepin content assay increased from 7.02 mg% to 8.66 mg%. The DPPH free radical scavenging activity of the fermented product was 91.92 EDA%, which was higher than that of the extract (84.69 EDA%). The ABTS free radical scavenging and superoxide dismutase (SOD) activities were also higher in the fermented products.

  • The purposes of this study were to isolate and characterize lactic acid bacteria with antibacterial activity against Methicillin-resistant Staphylococcus aureus (MRSA) from fermented food and to confirm the antibacterial activities of fermented rice products using the isolated lactic acid bacterium. Three bacteria, namely, Weissella sp. ISF-1, ISF-2, and ISF-3, were selected from fermented squid based on the 16S rRNA gene sequence. All three strains grew well in an MRS medium containing 5% (w/v) NaCl and showed antibacterial activity against Bacillus cereus, Staphylococcus aureus, and MRSA. Their growth was excellent at 0% ~ 5% (w/v) NaCl and relatively good up to 7% (w/v) NaCl. The initial pH of 8 was optimal for their growth, and good growth was also observed at pH 6, 7, and 9. The lyophilisates of the fermented rice using Weissella sp. ISF-1 showed antibacterial activities against B. cereus, S. aureus, and MRSA. We inferred that isolated lactic acid bacteria could be useful in the development of probiotics and biopreservatives for foods and in the treatment of MRSA and may increase the value of rice products.
