To enhance the physiological activity of the Rhynchosia volubilis (RV), R. volubilis (RVHE-A) and R. volubilis-added herbal powder (RVHE-B) were fermented with a solid state culture of Hericium erinaceum mycelia (HE). The total isoflavone contents of the non-fermented RV-A ($489.9{\mu}g/g$) and RV-B ($571.1{\mu}g/g$) were remarkably increased in fermented RVHE-A ($1,836.4{\mu}g/g$) and RVHE-B ($1,276.7{\mu}g/g$). In particular, aglycone isoflavones such as daidzein and genistein were significantly higher in the RVHE-A than any other sample. When hot-water (HW) and EtOH extracts (E) were fractionated from the RV and RVHE, both extracts from the RVHE-A were higher than those from the RV-A in total polyphenol and flavonoid contents. However, the RVHE-B-HW showed a lower polyphenol and flavonoid content level than did RV-B-HW. RVHE-A-HW and -E also had more potent ABTS radical scavenging activity than any extract from the non-fermented RV and other ferments (RVHE-B). In the meanwhile, RVHE-A-HW potently stimulated the production of macrophage activation-related cytokines such as $TNF-{\alpha}$, IL-6 and IL-12 ($841.7{\pm}71.3pg/mL$, $3.9{\pm}0.1ng/mL$, $179.3{\pm}30.2pg/mL$) from peritoneal macrophage more than RV-A-HW ($92.5{\pm}1.5pg/mL$, $0.1{\pm}0.0ng/mL$, $37.4{\pm}5.4pg/mL$) as well as RVHE-B-HW ($557.0{\pm}21.3pg/mL$, $1.8{\pm}0.0ng/mL$, $90.0{\pm}10.0pg/mL$). However, all the EtOH extracts did not show significant activity. In addition, the RVHE-A-HW showed a significantly higher intestinal immune system modulating activity through Peyer's patch and GM-CSF production than did any other extract from RV and RVHE-B. In conclusion, these results suggest that the fermented R. volubilis with H. erinaceum mycelia possesses a possible use as an industrial application as functional food or material.

This study investigated the changes of saponin and $\beta$-glucan content on the cultured ginseng with mushroom mycelia of Phellinus linteus (PL), Ganoderma lucidum (GL), and Hericium erinaceum (HE). Cultured ginsengs with mushroom mycelia were extracted with 80% ethanol, fractionated with n-buthanol, and analysed for ginsenosides by high performance liquid chromatography (HPLC). Crude saponin content of raw ginseng was 4.11% (d.b) but cultured ginseng with mushroom mycelia of PL, GL, and HE were increased to 6.74, 6.77 and 6.23% (d.b), respectively. Ginsenoside-Rd, among the 12 ginsenosides which were available for analysis, was remarkably increased to 13.61, 24.26, and 32.69 mg/g, respectively (raw ginseng: 0.80 mg/g). The $\beta$-glucan content of cultured ginseng with mushroom mycelia of PL, GL, and HE were decreased to 8.85, 5.51 and 5.46% rather than mushroom mycelia of 29.14, 19.44, and 23.39% (d.b), respectively.

This study investigated the fermentation effect of Taraxacum platycarpum Dahlst. leaf extracts using Hericium ernaceum mycelia to test antioxidant and anti-inflammatory activities in vitro. The antioxidant activities of fermented or non-fermented extracts of T. platycarpum leaves were determined by 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity, ferric reducing antioxidant power, and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity. The leaf extract of T. platycarpum showed higher antioxidant activity than extract of fermented leaves. However, ethanolic extract of fermented T. platycarpum leaves decreased levels of nitric oxide production and pro-inflammatory cytokines such as interleukin-6 and tumor necrosis factor-${\alpha}$ in lipopolysaccharide-stimulated RAW 264.7 cells. Moreover, fermented leaf extract suppressed protein expression of inducible nitric oxide synthase in RAW 264.7 cell culture. Therefore, the enhanced anti-inflammatory activity of ethanolic extracts of fermented T. platycarpum leaves might be attributed to the molecular conversion of leaf ingredients during fermentation and the active ingredients might have specific affinity with ethanol during extraction.

This study was conducted to investigate the antioxidant activities of the cultured ginseng with mushroom mycelia (Phellinus linteus (PL), Ganoderma lucidum (GL), and Hericium erinaceum (HE)) during cultivation periods of 10, 20, 30, 40, and 50 days. The lyophilized powder from the cultured ginseng with mycelia was extracted with 80% ethanol, and then evaluated for antioxidant activities. Total phenolic contents ranged from 149.63 to 205.91 mg/g, and the highest value was 80% EtOH extract from the cultured ginseng with GL at 30 days. The highest antioxidant activity ($IC_{50}$) for DPPH was 1.16 mg/mL in the cultured ginseng with HE at 40 days, and total antioxidant activity for ABTS was the highest value of 4.03 mg AA eq/g in PL cultivation at 30 days. $\alpha$-Glucosidase inhibitory activity was the highest value of 92.51% in EtOH extract from the cultured ginseng with PL at 50 days, and tyrosinase inhibitory activity was highest value of 13.21% in GL cultivation at 40 days. These results suggest that mushroom mycelium cultivation period for enhancement of antioxidant activity might be 40 days.

Three mushroom mycelia, Ganoderma lucidum, Hericium erinaceum, and Phellinus linteus, were separately diluted with the natural culture media Acanthopanax senticosus. Solid-state fermentation was used to produce three different A. senticosus-fermented mushroom mycelium groups: G. lucidum mycelia, H. erinaceum mycelia, and P. linteus mycelia. The resulting mycelia were analyzed to assess their efficacies as health functional foods. Optimized fermentation conditions were determined by considering the density and growth speed of mycelia in each A. senticosus-fermented mushroom mycelium group. The cultured mushroom mycelia under the optimized conditions were extracted using water and 70% ethanol. Extraction was followed by filtration, concentration and freeze-drying to produce extract powder of A. senticosus-fermented mushroom mycelia: Water extracts (FM-5111, FM-5121, and FM-5131) and 70% ethanol extracts (FM-5112, FM-5122, and FM-5132). Analysis of extract powder of A. senticosus-fermented mushroom mycelia was performed using the maker compounds eleutheroside B and eleutheroside E. Analysis of ${\beta}$-glucan contents was performed by enzymatic procedures.

This study was conducted to investigate the effects of fermented ginseng extract by mushroom mycelia on antiproliferation of cancer cells. Phellinus linteus, Ganoderma lucidum, and Hericium erinaceum mycelia were inoculated to ginseng. The effects of fermented ginseng extract on antiproliferation of stomach (MKN-45), colon (HCT116), mammary (MCF-7), lung (NCIH460), prostate (PC-3), and liver (HepG2) cancer cells were investigated by MTT assay. Fermented ginseng extract showed significant antiproliferation effects compared with fresh ginseng extract. Fermented ginseng extract by P. linteus, G. lucidum, and H. erinaceum mycelia showed growth-inhibitory effect of 44.50, 17.75 and 43.98% viability at 1.5 mg/mL on the MKN-45 cell line, 62.86, 3.73, and 54.55% at 1.5 mg/mL on the HCT116 cell line, 41.81, 7.01, and 37.84% at 1.5 mg/mL on the MCF-7 cell line, 53.52, 5.31, and 35.27% at 1.5 mg/mL on the NCIH460 cell line, 35.05, 3.07, and 44.29% at 1.5 mg/mL on the PC-3 cell line, and 59.57, 6.34, and 4.97% at 1.5 mg/mL on the HepG2 cell line, respectively. These results indicated that fermented ginseng by G. lucidum mycelium showed the highest antiproliferation effect against various cancer cells.

To obtain functional materials from a submerged culture of Hericium erinaceum, a suitable basal medium for flask culture was screened and the optimal culture conditions in a jar fermenter were investigated with the addition of ginseng extracts (GE) to the basal liquid medium. Of all tested basal liquid media, the mushroom complete medium (MCM) supplemented with 0.5% of GE produced the highest mycelial dry weight (MDW) of 5.91 g/L in the flask, which reached a plateau at $25^{\circ}C$, pH 5.5 after 10 days. The submerged culture conditions for the mass production of mycelia in a 50 L jar fermenter were also optimal at $25^{\circ}C$, pH 5.5, 120 rpm agitation speed and 0.4 vvm aeration rate. Under these conditions, the maximum MDW was produced, which reached a value of 4.28 g/L within 5 days. When we investigated the effects of the amount of GE in the MCM on the production of MDW in the jar fermenter, the addition of 5% GE (HE-GE-5) under the optimal culture conditions produced the maximum MDW (4.93 g/L). In addition, the crude polysaccharide of HE-GE-5 contained mainly neutral sugars (63.2%) with considerable amounts of uronic acid (19.3%) and a small amount of proteins (8.8%) and it had potent immunostimulation properties.

Green coffee beans (CB, Indonesian Mandheling) were fermented with three kinds of mushrooms (Phellinus linteus, PL; Hericium erinaceum, HE; Ganoderma lucidum, GL) or two kinds of mycelia from molds (Monascus purpureus, MP; Monascus ruber, MR) using solid-state culture to enhance physiological activity. After the roasting of fermented green coffee beans, roasted coffees were extracted with a hot-water decoction or 95% ethanol reflux. Yields from hot water extracts (HW, 17.7~25.3%) were higher than those from ethanolic extracts (EE, 9.5~12.2%). Hot-water extracts of roasted coffees from green coffee beans fermented with two molds (MP-CB-HW and MR-CB-HW) showed higher total polyphenols, flavonoids, and DPPH free radical scavenging activity than roasted coffees from non-fermented (CB-HW) or fermented green coffee beans with the three mycelia from mushrooms. MR-CB-HW also had the most potent macrophage stimulating and mitogenic activity (1.32 and 1.40-fold of CB-HW, respectively). In addition, MP-CB-EE and MR-CB-EE did not show any cytotoxicity to the RAW 264.7 cell at a concentration of $100{\mu}g/mL$, and these extracts significantly inhibited nitric oxide (NO) production from the LPS-stimulated RAW 264.7 cell line (38.6 and 37.0% of the LPS-treated group). Meanwhile, the chlorogenic acid concentrations of MP-CB-HW or MR-CB-HW highly increased (to 76.21 or $76.73{\mu}g/mL$, respectively), but caffeine concentrations were not affected by solid-state fermentation. In conclusion, the physiological activities of roasted coffees were enhanced by the solid-state culture of green coffee beans with M. purpureus or M. ruber, suggesting that these roasted coffees could possibly serve industrial applications as functional coffee beverages.

For the utilization of Korean ginseng (Panax ginseng C.A. Meyer) in the functional drink, we prepared the fermented Korean ginseng with mushroom mycelia (Ganoderma lucidum; WG-GL, Hericium erinaceum; WG-HE and Phellinus linteus; WG-PL) by solid culture. A proximate analysis showed that the fermented Korean ginseng contained significantly more crude fat (4.66$\sim$12.02%) than Korean ginseng (WG, 1.61%) whereas crude protein content of WG (13.64%) was higher value than those of the ferments (7.60$\sim$12.57%). When we also evaluated effects of the fermented Korean ginseng on the mitogenic activity, hot-water extract from WG-PL was significantly higher than those of WG or mycelia only fermentation (GL, HE and PL) as analyzed by IL-2 production (1.64-fold of the saline control) and proliferation of splenocytes (1.47-fold). In addition, the lysosomal phosphatase activity (WG-HE; 1.32-fold) and NO/TNF-$\alpha$ production (WG-HE; 2.27-fold of the saline control at 50 ${\mu}g$/mL, WG-PL; 3.56-fold, respectively) from macrophage in the presence of the fermented Korean ginseng were higher than those of WG or mycelia fermentation. These results indicate that hot-water extracts from the fermented Korean ginseng with mushroom mycelia by solid culture contain chemical ingredients different from the Korean ginseng, and that it might provide beneficial immunostimulating activity.

This study was performed to know the potentialities of the fruits of Opuntia ficus-indica, as a medium for mushroom mycelial culture. Five mushroom mycelial (Agrocus blazei, Grifola frondosa, Hericium erinaceum, Innonotus obliquus, Phellinus linteus) were frown on the malt extract broth (MEB) and the cactus broth medium (CB). The submerged culture mixtures were extracted using equal volume of ethyl acetate, and their extract yields, total polyphenol contents, and some physiological activities were compared with each other Each extract from mycelial culture grown on CB medium showed remarkable enhancement in physiological activities compared with each counterpart grown on MEB. Among five mycelial cultures grown on CB medium, the extract yield and polyphenyl content were highest in the extract from Grifola frondosa (extract yield, 0.4 g/L and polyphenol content, 22.7%). Also, the extracts from Grifola frondosa showed the highest physiological activities, such as DPPH radical scavenging ($IC_{50}=362.9{\mu}g/ml$), xanthine oxidase inhibition (about 80% at $500{\mu}g/ml$), and superoxide radical scavenging (about 80% at $500{\mu}g/ml$), and NO production inhibition ($IC_{50}=43.1{\mu}g/ml$) in LPS-stimulated RAW 264.7 cells. This result suggests that the fruit of Opuntia ficus-indica can be used as a culture medium for improving the functional properties of various mushroom mycelia.
