Abstract
In addition to fruiting bodies and mycelia, the mushroom residues have also been demonstrated to be rich in polysaccharides which have attracted academic attentions owing to their extensive bioactivities. Therefore, the present work aimed to investigate the potential hepatoprotective effects of Oudemansiella radicata residues polysaccharides (RPS). Our results demonstrated that RPS showed significantly protective effects against carbon tetrachloride (CCl4)-induced liver injury, and the possible mechanisms may be related with the predominant bioactivities of RPS containing anti-oxidation by activating the Nrf2 signal pathways, anti-inflammation by inhibiting NF-κB signal pathways and reducing the release of inflammatory cytokines, anti-apoptosis by regulating Bcl-2/Bax pathway, and anti-fibrosis by inhibiting the expressions of TGF-β1, Hyp and α-SMA, respectively. These findings suggested that RPS, a typical β-type glycosidic pyranose-polysaccharides, could be used as promising diet supplement or medication for the adjunctive treatment of hepatic diseases, and also contributed to promoting the recyclable utilization of mushroom residues.

Abstract
The purpose of this study is to evaluate the bioaccessibility of nutrients and antioxidant activity of O. radicata after subjecting to four types of domestic cooking and followed by in vitro digestion. The result demonstrated that the group with the lowest amino acid release and the degree of protein hydrolysis (5.6%) was frying, but both reducing sugar content and antioxidant activity were the highest. The composition of fatty acids was different than undigested samples, especially the relative content of linolenic acid was significantly decreased (e.g., 34.49 to 8.23%, boiled). The difference of the minerals bioaccessibility was slightly affected by the cooking method, but mainly related to their natural properties, such as the highest phosphorus (62.73%) and the lowest iron (21.53%) in the steaming. The above data provides a starting point for the design of processes at an industrial and gastronomic level.

Abstract
This study investigated the removal and translocation mechanism of cadmium (Cd) by Oudemansiella radicata (O. radicata) in mushroom-soil rhizosphere and the fruiting body of mushroom. For this, the biomass, physiochemical parameters, and Cd distribution of O. radicata were examined in the soil spiked with 0, 10, 20, and 30 mg kg-1 Cd. The soil microecology and the Cd fractionation in the soil rhizosphere were also measured. Results showed that, O. radicata possesses high capability to tolerate Cd, although its surface phenotypic structure was influenced by high concentrations of Cd. The observed concentrations of Cd in O. radicata were in the following order: root (the part of stipe in soil) > pileus > stipe. The presence of Cd led to an increase in the production of antioxidant enzymes and glutathione (GSH). These results suggested that antioxidant enzymes and GSH assisted detoxification and accumulation of Cd within the mushroom. Meanwhile, in the soil rhizosphere, the concentrations of oxalic, citric, and malic acids were enhanced with the treatment of Cd, indicating that the production of these acids was closely related to the presence of Cd in soils. Additionally, the proportion of acid-soluble Cd was increased and the soil microecology (microbial counts, urease, and acid phosphatase activities) also enhanced with the inoculation of O. radicata. Overall, this study demonstrated that O. radicata is a promising candidate for the remediation of Cd-contaminated soil.

Abstract
In this study, a 39-kDa metalloprotease was purified from a rare edible mushroom with health-promoting activities, Oudemansiella radicata, using a purification protocol which entailed anion exchange chromatography on DEAE-cellulose and Q-Sepharose columns and gel filtration by fast protein liquid chromatography on a Superdex 75 column. Some peptide sequences were obtained by LC-MS/MS analysis and one of the sequences, DAWIQADVNR, manifested 90% identity to Coprinopsis cinerea metalloprotease. The optimal reaction pH and temperature for Oudemansiella radicata protease were pH 7.0 and 50°C, respectively. The protease was purified 79-fold and demonstrated a specific protease activity of 2.42 U/mg. The Km of the purified protease for the casein substrate was 0.65 mg/mL at pH 7.0 and 50°C. The activity of the protease was inhibited by Cd2+, Hg2+, Cu2+, Pb2+ and Fe3+ ions, but was enhanced by K+, Mn2+ and Fe2+ ions. The marked suppression of the protease activity by EDTA indicates that the protease is a metalloprotease.

Abstract
The preliminary structure, in vitro antioxidant and in vivo hepatoprotective activities of water-soluble polysaccharides (ORWP) and alkali-soluble polysaccharides (ORAP), prepared from the mushroom Oudemansiella radicata, were investigated. Both ORWP and ORAP were heteropolysaccharides with mannose, glucose and galactose being the main monosaccharide components. Regarding the antioxidant activities, ORWP and ORAP showed effective 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, hydrogen peroxide scavenging activity and lipid peroxidation inhibitory effects, as well as moderate reducing power and Fe2+ chelating activity. For the hepatoprotective activity, administration of ORWP and ORAP prevented the increase in serum alanine aminotransferase and aspartate aminotransferase activities in a carbon tetrachloride-induced acute liver damage model, suppressed hepatic malondialdehyde formation and stimulated the activities of hepatic superoxide dismutase and glutathione peroxidase. Thus, we speculate that ORWP and ORAP may protect the liver from CCl₄-induced hepatic damage via antioxidant mechanisms.

Abstract
Oudemansiella radicata has been found to have ability to tolerate and accumulate heavy metals. In this study, to know about the metal tolerance and detoxification strategy of O. radicata, the tolerance responses in both cap and stipe of the fruiting body, including the copper content, the changes of thiol compounds production and antioxidant enzymes activities, caused by various copper stress (150-600 mg kg(-1)) during 2-6 days were investigated. Results showed that Cu content in the fruiting bodies increased with the increasing Cu concentrations and growing time, which was higher in cap than that in stipe. For thiols contents, the maximum level was in the sample at 300 mg kg(-1) Cu after 2 d both in cap and stipe, in accordance with superoxide dismutase (SOD) and glutathione reductase (GR) activities. Guaicol peroxidase (POD) activities reached maximum at 150 mg kg(-1) Cu after 4 d and 6 d, respectively in cap and stipe, while the maximum of catalase (CAT) activities was recorded at 300 and 600 mg kg(-1) Cu after 4 d in the cap and stipe, respectively. As a whole, low concentration of Cu stimulated the production of thiols and activated the antioxidant enzymes activities in the fruiting body of O. radicata after 2/4 d, while high-level Cu decreased the thiols production and enzymes activities after 4/6 d. Furthermore, the cap was more sensitive than the stipe to Cu exposure. Different indicators showed different responses to copper accumulation and the different fruiting part (cap and stipe) of O. radicata had ability to response the oxidative stress caused by Cu. Considering the metal accumulation and its own detoxification with short growing time, mushroom might have the potential to be used as bio-accumulator to deal with Cu exposure in the Cu-contaminated farmland soil.

Abstract
To screen additives and their mixed ratio suitable for the mycelial growth and fruiting body formation of Oudemansiella radicata in the oak sawdust, additives such as rice bran, fermented soybean powder and wheat bran were used. Generally, the mycelial growth of O. radicata has been stable on oak sawdust mixed with rice bran of 5~20%. In case that O. radicata was cultured for about 30 days at 22 ± 1℃ under the illumination (350 lux) of 12 hours and moisture condition of 90 ± 5%, the primordia have been formed gradually from red-brown crusts covering the surface of oak sawdust media. Based on the experimental results from 9 strains of O. radicata, fruiting bodies were produced widely on oak sawdust medium mixed with rice bran of 5 to 30%. Even though fruiting bodies of O. radicata have been produced well on oak sawdust media mixed with rice bran, fruiting bodies of O. radicata were produced intensively on oak sawdust media mixed with rice bran of 10%. Therefore, this result will provide a basic information for commercial production of fruiting body of wild O. radicata. This result is the first report associated with an artificial fruiting body formation of O. radicata in Korea.

Abstract
Oudemansiella radicata, one of edible mushrooms belonging to Tricholomataceae of Basidiomycota, has been known to exhibit outstanding therapeutic effects on the hypertension caused by high blood pressure and inhibitory effects on the sarcoma 180 and Erhrlich carcinoma of mice. As one of preliminary experiments for producing fruiting-body of O. radicata, this study was carried out to obtain the basic information for culture conditions of mycelial growth of the fungus. The optimal temperature and pH for the mycelial growth were 25℃ and pH 6, respectively. The medium for favorable mycelial growth of O. radicata was shown in the Lilly medium, whereas compact mycelial density was found in Hamada medium. The carbon and nitrogen sources promoting for mycelial growth of O. radicata were xylose and alanine, respectively. The optimum C/N ratio was about 20 : 1 in case that 3% glucose was supplimented to the basal medium as a carbon source.
