  • Present experiments were conducted to determine the possibility of artificial culture with oak sawdust block of Phellinus gilvus Mushrooms, Mycelial growth in sawdust block (oak 90 + rice bran 10, V/N) after 25 days. It took 12 days to make fruitbody from burying of sawdust block to pinhead formation. The fruitbodies produced the total fresh weight 577 g (dried weight 97 g) in a block.

  • This study was carried out to develop optimum sawdust medium for bottle cultivation of Pholiota adiposa. Five kinds of sawdust media were tested. Period of primordial formation was shorter 1-5 days in T3 and in T4 than in other treatments. Total cultivation period was 3-5 days longer in treatments including oak sawdust than in T5, treatment of poplar+rice bran(8:2). Stipe diameter, stipe length, and number of valid stipe were the biggest in T3. Yield of fruiting body was increased 33% in T3 and 12% in T4, respectively compared to T1 as control. Therefore, T3, treatment of oak sawdust+beet pulf+cottonseed meal(5:3:2), would be appropriate for the commercial production of Pholiota adiposa by bottle cultivation.

  • After examining the temperature change in berry sawdust during the fermentation period and the developmental characteristics of Protaetia brevitarsis larvae according to the fermentation period, it was found that the fermentation speed was faster than with oak sawdust and a fermentation period of 50-70 days was the most suitable for larval growth. During the fermentation period, the temperature change in sawdust was quickly fermented as berry sawdust passed a high temperature of more than 60℃ in the early stages of fermentation compared to fermentation speed of oak sawdust, and stabilized within 60 days. In individual breeding, the total growth period of P. brevitarsis larvae by fermentation period was the longest at 104.8 days after fermentation for 30 days, which was a significant difference. There was no difference in the growth period between 50 and 90 days of fermentation. Oak sawdust tended to be the same as berry sawdust, but the larval development period was approximately 30 days. The developmental period by larval stage differed greatly between berries and oak sawdust. The weight of larvae according to the fermentation period of sawdust was the lowest after 90 days of fermentation, with a long fermentation period for both berry and oak sawdust, and there was no difference in the 30-70 days fermentation periods. The survival rate was more than 95% in individual breeding, and there was no difference among the fermentation periods. However, in group breeding, the survival rate was lower than that of individual breeding and was lowest at 90 days of fermentation. In group breeding, the ratio of larvae weighing ≥ 2.5 g, which is the standard for shipment, was 85% after 30-70 days of fermentation of berry sawdust, but was lower at 70% after 90 days of fermentation, which was a significant difference. The survival rate with oak sawdust showed the same trend, which was approximately 10% lower than that with sawdust. In addition, the larvae from the berry sawdust weighed > 2.5 g in 40-60 days, while it took 75-105 days with oak-fermented sawdust.

  • Some factors effecting on the mycelial growth and primordia formation of Agrocybe cylindracea were investigated. Among supplements added into sawdust, wheat bran was the best for the mycelial growth, and its appropriate concentration was 30%. A variety of sawdust preparations was tested singly and in combinations. Oak sawdust and the combination of oak and larch sawdust were the most effective for the mycelial growth. The optimal moisture content was 65%, and the range of optimal temperature was $25\:{\sim}\:28^{\circ}C$. The favorable conditions for the primordia formation appeared to be similar to those of the mycelial growth. Among supplements added into sawdust, wheat bran 30% and the combination of wheat bran and rice bran 30% were the best for the primordia formation. Oak sawdust, and the oak plus larch sawdust and oak plus poplar sawdust were the best for the primordia formation. The optimal temperature for the primordia formation was $17{\pm}2^{\circ}C$.

  • For artificial cultivation of Phellinus pini (Thore. Fr.) Ames, we conducted some study on mycelium growth and optimum condition for fruitbody formation. The optimum condition for mycelial growth was $25{\sim}30^{\circ}C$ at pH $5.0{\sim}6.0$. Optimum sawdust media were oak sawdust+willow sawdust+rice bran (4.5:4.5:1, V/V) and oak sawdust+pine sawdust+rice bran (4.5:4.5:1, V/V) and the optimum spawn incubation period was about $33{\sim}34$ days. Mycelial growth in the inner portion of oak log was 40 mm after 60 days and duration for first fruitbody primordia formation was about 110 days after inoculation.

  • For artificial cultivation of Phellinus baumii, we have conducted a study on cultural characteristics and condition of fruitbody formation in sawdust cultivation. Mycelial density and incubation rate were higher in oak sawdust+rice bran (4 : 1) medium than oak sawdust 100% medium. However, primordia and fruitbody formation were higher in oak sawdust 100% medium than rice bran added medium. Bigger bottle capacity (1,100 ml) resulted in a little higher yield and more biological efficiency than 850 ml bottle.

  • The adsorption and reduction characteristics of chromium(VI) by oak sawdust were studied. The optimum adsorption condition is obtained from the measurement of the distribution coefficient($K_d$) and adsorption capacity of Cr(VI) on the sawdust by changing pH of the solution. As a result, it was found that pH 2.0 was optimum because $K_d$ of Cr(VI) was maximum and reducing quantity was minimum. By the use of these characteristics of the oak sawdust, the removing of Cr(VI) in industrial waste water was examined.

  • High-income mushroom crops require complex farming. Therefore, we conducted a test to identify the optimum temperature for the production of antler-shaped Ganoderma lucidum using the King Oyster mushroom cultivation facility. T-N showed 0.28% of oak sawdust and 2.2% of nutritional source. The pH of oak sawdust was 6.0, indicating weak acidity, and that of rice steel was 6.6, indicating neutrality in nutrition source. Study on the quality characteristics of mushrooms showed that the number of days at 25℃ were 5~6 and those at 30℃ were 3~5; the representative length at 25℃ was 57.5 mm and that at 30℃ was 92.2 mm; the biological weight at 25 ℃ was 43 g, which was greater than that at 30℃.

  • The objective of this study was to evaluate the antioxidant activity of extracts of Protaetia brevitarsis larvae fed on fermented oak sawdust (FOS) or spent mushroom substrates (SMS, Pleurotus eryngii). Total polyphenol content was 32% higher in extracts of larvae fed on SMS (P. eryngii) (75.33±0.43 mg GAE/g) than in extracts of larvae fed on FOS (57.02±1.73 mg GAE/g). The flavonoid content of extracts of larvae grown on FOS and SMS (P. eryngii) was 24.6±0.28 mg/g and 25.4±0.75 mg/g, respectively. DPPH radical scavenging activity increased in an extract concentration-dependent manner, and the DPPH radical scavenging capacity of the extract of larvae produced on SMS (P. eryngii) was higher than that of the larvae produced on FOS. The reducing power of the larval extracts produced on FOS and SMS (P. eryngii) increased in an extract concentration-dependent manner, but there was no significant difference between them. The extract of larvae fed on SMS (P. eryngii) (66.55±0.99 uM TE/g) had a higher oxygen radical absorbance capacity (ORAC) than extracts of larvae grown on FOS (76.32±0.48 uM TE/g). The effect of larval extracts on cell proliferation was investigated using a WST-1 (4-[3-(4-iodophenyl)-2-(4-nitrophenyl)-2H-5-tetrazolio]-1,3-benzene disulfonate) assay on RAW 264.7 cells. When cells were treated with larval extracts produced on FOS and SMS (P. eryngii) at concentrations of 0, 2, 4, 8, 16, 32, 40, and 64 mg/ml, RAW 264.7 cells proliferated at 90% or more. Therefore, larval extracts produced on FOS and SMS (P. eryngii) were not toxic to RAW 264.7 cells.
