  • Six strains of Sparassis crispa such as S. crispa DUM-01, DUM-02, DUM-03, DUM-04, DUM-05, and DUM-06 were tested for their mycelial growth on 6 different kinds of sawdust media and primordial formation on 10 different compositions of larch sawdust media. The highest mycelial growth was recorded on the larch sawdust. Of the 6 strains of S. crispa, S. crispa DUM-04 recorded the favorable formation of primordia. The primordial formation of S. crispa DUM-04 was more favorable on L-3 medium than 9 kinds of larch sawdust media. When S. crispa DUM-04 was cultured on the media of larch sawdust+pine sawdust, the formation of its fruiting bodies was more outstanding on the media of larch sawdust+pine sawdust than those of larch sawdust.

  • The major substrates used in soilless growing media are peat moss and perlite, where peat moss is a limited and expensive natural resource. Determination of appropriate substrates based on technical and economic feasibility is the vital aspect of research and the key to success in any soilless production system. This research work was performed to evaluate different low-cost and sustainable alternative substrate as soilless growing media for horticulture plant. The objective of this study was to compare the effect of sawdust species and steam treatment, for physico-chemical properties and growth of horticultural plant. This study involves the physical and chemical characterization and growth test of four substrate (pine sawdust, oak sawdust, steamed pine sawdust and steamed oak sawdust) in order to evaluate their use as components of growing media. Steamed oak sawdust ($121^{\circ}C$, 30 min) showed adequate physical and chemical properties compared to peat moss for their use as growing media. The growing media were prepared using different mixture proportion to grow Brassica campestris L., Festuca arundinacea and Lespedeza cyrtobotrya Miq. The highest germination, stem length and leaf area of Brassica campestris L., Festuca arundinacea and Lespedeza cyrtobotrya were observed in 30 minute steamed oak sawdust mixture growing media. The steam treatment condition of sawdust used in the growing media significantly positive affected the germination, the stem length and the leaf area.

  • This study was carried out to investigate the physiological charateristics of F. pinicola in sawdust media. The optimum temperature in sawdust media was $30^{\circ}C$ in of F. pinicola. The optimum pH was 5 in F. pinicola. Mycelial growth and density of F. pinicola was quite good when birch tree and oak sawdust, respectively were used as cultural substrates. The best mycelial growth in F. pinicola was observed when beer waste was added as supplement on sawdust substrates. The optimum supplement ratios of beer waste and a magnecium sulfate were 20%, and 0.1% respectively. However, optimun supplement ratios of a calcium oxide and a LVD were different as 0.1% in F. pinicola.

  • Saesongi (Pleurotus eryngii) was cultivated in both potato dextrose agar (PDA) and sawdust media supplemented with Ca salts. The addition of Ca phosphate and Ca carbonate to sawdust media did not affect the growth, whereas Ca sulfate addition suppressed the mycelial growth appreciably. The efficiencies of Ca accumulation in the fruiting were studied based on mycelial growth experiments on Ca-supplemented sawdust media. Supplementation with 0.1 to 5% Ca phosphate increased the Ca content in the fruiting body by 4.5-6.5 fold, to a level of $314.6{\pm}22.7$ to $449.7{\pm}29.3$.

  • 4 strains of the oak mushroom Lentinus edodes including the strain ASI 3046 were collected home and abroad to investigate the characterics of mycelial growth on synthetic media and sawdust media. The possibility of artificial culture of Lentinus edodes on media composed of different saw dusts and adding materials was investigated. Results were as follows: The optimum temperature for growth ranged from $22^{\circ}C$ to $26^{\circ}C$ among the lineages of Lentinus edodes. The optimal growth temperature for ASI 3046 strain and ASI 3047 strain was $26^{\circ}C$ and $22^{\circ}C$, respectively. The optimal carbon source for ASI 3046 strain was glucose, and peptone and ammoinum tartrate were proved excellent as nitrogen sources. When Lentinus edodes was cultured on sawdust media by varying the mixing ratio of different sawdusts and adding materials, mixed sawdust media composed of oak sawdust(50%, v/v), poplar sawdust(50%, v/v), acorn powder(5%, v/v) and rice bran(10%, v/v) showed higher yields of fruit bodies. Results showed that the ideal strain of Lentinus edodes for artificial culture on sawdust media was strain ASI 3046.

  • These experiments were conducted to search for the optimum media size and composition for culture of Lentinula edodes (JNM3022). Considering the incubation period and the successful culturing rate, the optimum media size was length 25 $cm{\times}diameter$ 14 cm (weight 2.5 kg). The saturation moisture amount of Oak sawdust was 251 ml/100 g. It is a half of pine sawdust 495 ml/100 g. Considering the hypha growing speed and hypha density, the optimum media composition was Oak sawdust 80%+ wheat bran 20% and Oak sawdust 80%+ rice bran 20% In 10 treatments of media composition. The optimum moisture amount of media for growing Lentinula edodes (JNM3022) was 55%. Injection pipe with 20 holes in media was reduced the incubation periods to 11 days when 20cm length media and 32 days when 30cm length media compare to control. The best method for browning media surface was change temperature condition above $10^{\circ}C$ and punching the vinyl bag. This treat could shortened the browning periods to 54 days.

  • To produce fruiting bodies of Oudemansiella mucida, porcelain fungus, on the oak sawdust medium, additives suitable for the mycelial growth and fruiting body formation were screened. In general, the mycelial growth of the three strains of O. mucida used in this study have been good on oak sawdust mixed rice bran of $20{\sim}30%$. The mycelia incubated in potato dextrose broth for 7 days were inoculated on oak sawdust medium supplemented with various ratios of rice bran and incubated for 30 days at $25^{\circ}C$ in the dark condition until the mycelia of O. mucida fully colonized the media from top to bottom. Then, top surface of the media in the bottles were horizontally scratched with a spatula and filled with tap water for 3 hours. To induce the primordial formation of O. mucida, the bottles were transferred to the mushroom cultivating room under 12 hrs of light (350 lux) and dark condition with relative humidity of 95% at $17^{\circ}C$. The primordia of O. mucida were formed on the surface of oak sawdust media after 7 days of incubation. The mature fruiting bodies were observed 5 days after primordial formation. The fruiting bodies O. mucida were formed on oak sawdust medium mixed with 5 to 30% rice bran. However, abundant fruiting-bodies of O. mucida were produced in oak sawdust medium supplemented with 20% rice bran. This is the first report associated with an artificial fruiting body production of O. mucida in Korea.

  • Dairy manure amended with crop and forest residues (moisture 69% wet basis, C/N 22) was composted in a 605 L pilot-scale vessel using continuous air flow (56 L/min) for 19 days. Three pilot-scale sawdust biofilters (moisture 63%, pH 5.0) were built to clean biological waste gas from the composting process. For each methods, two replicated experiments were monitored over a period of three weeks. The system was evaluated to determine the biofilter media depth that would be adequate for compost odour reduction. The compost air cleaning was measured based on ammonia gas concentration before and after passing through the biofilter. Ammonia gas removal efficiency over 3 weeks was 42, 75 and 87% at sawdust biofilter media depth levels of 202, 400 and 600 mm, respectively. Each sawdust biofilter was operated at a moisture content in the range of 60~62% (wb), a temperature from 15 to $25^{\circ}C$, an average pressure drop from 240 to 340 Pa and a detention time from 60 to 180 seconds during the biofiltration process.
