The mushrooms collected at seven areas of Mt. Chiak in 2002 and 2003 were classified to analyse the distribution and species diversity. Frequency (number of mushroom : N), number of species (S), relative species density (RSD), similarity index (C), richness index (R1), variety index (V1), evenness index (E2), and dominance index(D1) were investigated. Total N and S was 143 and 84, respectively. The RSD was 0.179 ~ 0.226 of the 7 areas. The yearly C of the total area (0.213) was 8.2%. more higher than the average C of 7 areas (0.131). The order in the coefficient of variation (CV) of the indicator for 7 areas was N (10.5%) > D1 (9.2%) > V1 (8.9%) > S (8.5%) > R1 (7.4%) > E2 (2.2%). The average R1 of the 7 areas was 5.36 with the range from 4.85 to 6.01, and 16.72 for the total area. The average V1 of the 7 areas was 16.24 with the range from 14.44 to 18.66, and 68.82 for the total area. The average E2 of the 7 areas was 0.95 with the range from 0.926 to 0.982, and 0.819 for the total area. The average D1 of the 7 areas was 0.071 with the range from 0.055 to 0.073, and 0.081 for the total area. The correlation between N and 5 kinds of diversity indicator (S, R1, V1, E2, D) was not statistically significant, but the correlation between R1, E2 and D1 was statistically significant each other.

Microbial diversity of soil samples from ancient stone-lined tombs was investigated. The tombs, discovered at Eoryung Ocheon-Ri site, Korea, were estimated to be belonged to middle class people from an ancient country, Gaya, which existed till AD 559 at the southern part of Korea. Nine fungal stains and 70 bacterial strains were isolated from the twelve soil samples, which were collected from the tomb Nos. 5 and 6. Ribosomal DNA sequence analysis discovered 5 fungal and 22 bacterial strains belonged to 10 genus groups from the tomb No. 5 while 1 fungal and 28 bacterial strains belonged to 6 genus from the tomb No. 6. The higher microbial diversity suggests that the tomb No. 5 was constructed warmer season than the tomb No. 6. Moreover, the discovery of Staphylococcus warneri, which is found as part of the skin flora on human and animals, and Bacillus aquimaris, which is a marine bacterium and can be discovered from tidal flat, from the surface of large dagger suggests that the ancient people may use meat and seafood at the burial ceremony.

Fourteen new records of yeasts were screened from one hundred thirty-three yeasts strains which were isolated from wild flowers in east, west and south coast near areas and inland areas, Korea. Candida silvae, Cryptococcus terrestris and Auriculibuller fuscus were newly isolated from wild flowers collected at Donghae and Andong, respectively. Candida quercitrusa, Hanseniaspora opuntiae, Sporobolomyces carnicolor, Candida saopaulonensis and Sporobolomyces phaffii were newly isolated from wild flowers in Geumsan-gun and Taean-gun in Chungcheongnam-do, respectively. Candida oleophila and Jaminaea angkoriensis were newly identified from flowers in Yesan-gun and Hannaella zeae was also newly identified from flowers of Daecheon. Hanseniaspora vineae and two other yeast strains including Pseudozyma hubeiensis were newly isolated and identified from flowers collected at Gwangju and Wando-gun, respectively. Morphological and physiological characteristics of their new recorded yeasts were investigated.

DOI : 10.4489/KJM.2013.41.2.81
The purpose of this study was to investigate effects of inoculation of arbuscular mycorrhizal fungi (AMF) on growth of Korean ginseng (Panax ginseng C. A. Mey.) seedlings. Five species of AMF (Glomus mosseae, Glomus intraradices, Glomus etunicatum, Acaulospora longula, Acaulospora trappei) were inoculated to ginseng seedlings at 60 days after ginseng seed germination. Dry weights, heights of the plants and chlorophyll fluorescence were measured at 120 days after inoculation of AMF. Dry weights and shoot heights were increased in seedlings inoculated with AMF compared to the controls without AMF. However, chlorophyll fluorescence of seedlings with AMF showed no significant difference compared to the control.

DOI : 10.4489/KJM.2013.41.2.85
This study investigated the internal and external morphological characteristics of decomposition and browning of oak sawdust medium for ground bed cultivation of Lentinula edodes. Within fifty days after L. edodes inoculation, surface hyphae on the bed browned. In 110 days, the fungal hyphae occupied and decomposed wood fibers, vessels and parenchymatous cells from the inside as white profuse hyphal mass was amorphously dissolving the saw dust particles from the outer surface. Most of the white hyphal bed surface became cleanly brown, however, some colony surface became blackened and slimy with contaminating bacteria, hyphae and spores. The brown layer was ca. 0.34 mm thick with highly dense and white hyphal mass beneath, whereas the blackened layer was ca. 1.17 mm thick with shrunken hyphae and less decomposed sawdust particles beneath. The surface hardness of the brown surface was ca.
, soft and resilient, while that of the blackened was ca.
, hard and nonresilient. By 150 days Lentinula edodes mushrooms fruited only on the brown surface and not on the blackened medium.

DOI : 10.4489/KJM.2013.41.2.91
Two strains Pleurotus eryngii 'Aeryni' and 'Na' carrying superior traits of a pileus and a earliness of harvest were selected to improve previously bred strains by single crosses. New hybrid, Aeryni 3 (Aeryni10
Na5) showed superiority to other hybrids in yield, fruit body shape and days for harvest. The new strain, Aeryni 3 was harvested earlier than Keunneutari No. 2 by 2~3 days, and yielded 110.5 g/bottle (850 mL) which was 108% of that of Keunneutari No. 2. The ratio of diameter of pileus and stipe was 1.8 indicating that new stain will be likely low damage rate of fruit body during a distribution, and that was better than 2.1 of Keunneutari No. 2. A sensory test of taste of the new strain showed that 84.7% of evaluation panels selected "very good" while that of Keunneutari No. 2 was 55.5%. In purchasing intent test, 86.9% of panels will buy the new stain whereas 46.8% will buy Keunneutari No. 2 implicating that the new strain will likely be more marketability than previously bred strain.

Pholiota nameko is an edible mushroom belonged to Family Strophariaceae of Agaricales, Basidiomycota. The purpose of this study was to investigate the antioxidant and anti-inflammatory activities for the methanol and hot water extracts prepared from fruiting bodies of Pholiota nameko. Besides measuring for 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, a reducing power and a chelating activity on ferrous ions were also measured to evaluate the antioxidant activity for those extracts. To measure the anti-inflammatory activities for the extracts, nitric oxide(NO) production from lipopolysaccharide treated RAW 264.7 macrophage cells and carrageenan-induced acute hind paw edema of rats were investigated. The results showed that those extracts has a excellent chelating activity on the ferrous ions compared with positive controls. And it also turned out that extracts had a good DPPH activity and a reducing power. The NO production in LPS-treated RAW 264.7 macrophage cells were decreasing as we increased concentration of those mushroom extracts. Significant reduction of paw edema were also observed at 2~6 h after we treated methanol and hot-water extracts at the 50 mg/kg concentration to the rats which are induced acute hind paw edema by carrageenan treatment. The experimental results suggested that methanol and hot-water extracts of Pholiota nameko fruiting bodies might be used for potential source of antioxidant and anti-inflammatory agents.

Phellinus baumii is a medicinal mushroom used in Asian countries for a long period of time. The purpose of this study was to investigate the skin whitening activities of methanol extracts from fruiting bodies of P. baumii. To evaluate the antioxidant activities of the extract, polyphenol and flavonoid contents, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity and chelating activity on ferrous ions were studied. For assay of skin whitening activities, tyrosinase and DOPA inhibitory activities, and tyrosinase and melanin synthesis inhibitory activities of B16/F10 melanoma cells treated with the methanol extract were investigated. The total polyphenol content of P. baumii methanol extract was 4.19. DPPH scavenging ability of P. baumii methanol extract was 88.26% in
concentration. We tested tyrosinase inhibitory activity and melanin contents in melanoma cells. The tyrosinase activity was inhibited to 65.17% at the concentration of
and melanin synthesis was inhibited to 57.61% at the concentration of
. Overall, the experimental results showed that P. baumii methanol extract had inhibitory activities of tyrosinase and melanin synthesis by dose dependent manner in B16/F10 melanoma cells. Strong ultra-violet absorption spectra in the range of 270~370 nm indicated that ethanol extract of P. baumii could protect the skin from UV. Therefore, P. baumii methanol extract might be used for development of skin whitening, anti-UV and skin care agents.

Phytophthora capsici is one of major limiting factors in production of pepper and other important crops worldwide by causing foliage blight and rot on fruit and root. Increased demand for the replacement of fungicides has led to searching a promising strategy to control the fungal diseases. To meet eco-friendly agriculture practice, we isolated microorganisms and assessed their beneficial effects on plant health and disease control efficacy. A total of 360 bacterial strains were isolated from rhizosphere soil of healthy pepper plants, and categorized to 5 representative isolates based on colony morphology. Among the 5 bacterial strains (GJ-1, GJ-4, GJ-5, GJ-11, GJ-12), three bacterial strains (GJ-1, GJ-11, GJ-12) presented antifungal activity against P. capsici in an fungal inhibition assay. In phosphate solubilization and siderophore production, the strain GJ-1 was more effective than others. The strain GJ-1 was identified as Bacillus sp. using 16S rDNA analysis. Bacillus sp. GJ-1 was also found to be effective in inhibiting other plant pathogenic fungi, including Rhizoctonia solani, Pythium ultimum and Fusarium solani. Therefore, the Bacillus sp. GJ-1 can serve as a biological control agent against fungal plant pathogens.

The experiment was carried out to analyze the inhibition effect of plant pathogenic fungi and growth promotion activity induced by the bacterial strains isolated from peatmoss. Among the isolated bacterial strains, B10-2, B10-4, B10-5 and B10-6 which showed more than 30% inhibition rate against Botrytis cinerea and Rhizoctonia solani in vitro, were further analyzed in the greenhouse for the growth promotion activity on lettuce (Lactuca sativa), pak-choi (Brassica compestris L. ssp. chinensis) and Chinese cabbage (Brassica campestris L. ssp. pekinensis). The results showed the treatment of B10-4 on lettuce showed the highest growth promotion activity with the leaf area (
), fresh weight (leaf: 40.29 g, root: 8.80 g)and dry weight (leaf: 11.24 g, root: 4.17 g), which was about two folds as compared to control. On pak-choi, the growth promotion rate was the highest with the leaf area of
, leaf fresh weight of 60.70 g, root fresh weight of 3.37 g, leaf dry weight of 14.34 g, and root dry weight of 1.90 g. As a result of treatment of B10-13 on chinese cabbage, the growth promotion rate was the highest with the leaf area (
), fresh weight (leaf: 113.67 g, root: 2.40 g) and dry weight (leaf: 6.03 g, root: 0.53 g). The production of Indole Acetic Acid (IAA) and Indole-3-Butylic Acid (IBA) were also analyzed in these bacterial isolates. The IAA and IBA analyses were carried out in all bacterial isolates each day within the 5 days of incubation period. The highest production of IAA was observed with
protein in B10-4 after 3 days of incubation and IBA production was the highest in B10-2 with
protein after 2 days of incubation. Also, phosphate solubilizing activity was expressed significantly in B10-13 in comparison to that of other bacterial isolates. Bacterial identification showed that B10-2 was Bacillaceae bacterium and B10-5 was Bacillus cereus, B10-4 and B10-6 were Bacillus sp. and B-13 was Staphylococcus sp. by ITS sequence.

Black Aspergillus is important fungus for oriental fermentation industry. Black Aspergillus was frequently isolated from Korean traditional Meju, a fermented soybean starting material for soy sauce and soybean paste. Thirty three strains were isolated from 98 finished Meju collected in various regions of Korea from 2008 to 2011, and 21 strains were isolated from in-process Meju at various farms from 2010 to 2011. The isolated black Aspergillus were identified using DNA sequences of partial
-tubulin and calmodulin genes. Of 54 black Aspergillus strains, 14 strains were identified as A. luchuensis and the others were composed of A. niger (n = 21), A. tubingensis (n = 10), and A. welwitschiae (n = 9).
