  • Mummy disease has been observed for a long time in the button mushroom, Agaricus bisporus farms in Korea, and severe mummy disease occurred on “Shinryung” mushroom, A. blazei recently. Typical symptoms of mummy disease were observed on the mushroom-cultivation beds infected ; tilted caps of mushrooms, browning and lignified internal tissue of stipe, overdevelopment of mycelium around the base of the stipe, and mummified mushrooms. Electron micrographs prepared from internal tissue of stripe of the diseased mushrooms showed that many bacterial cells present inside hyphal cells of the diseased mushroom, which is one of the characteristics of mummy disease reported previously, Survey in Buyo, Chungnam showed that mummy disease occurred at 55% and 83% frequency on bottom mushroom (brown strain) and “Shinryung” mushroom cultivation during year 2000. It indicates that mummy disease is one of the major diseases for the mushrooms cultivation.

  • The study was carried out on the artificial cultivation of the abalone mushroom, Pleurotus cystidiosus O.K.Miller. The pine sawdust substrates with 20% rise bran were good for mycelial growth and high quantity of P. cystidiosus in the bottle cultivation. Moreover, the proper volume for bottle cultivation was 850 ml and the removal of spawn and surface layer of the medium before pin-heading was more efficient. The yields of P. cystidiosus were higher in sawdust substrates added calcium carbonate than those not added calcium carbonate. The volume of 3 kg polypropylene bag is good for yield and biological efficiency in bag cultivation of P. cystidiosus. Cotton wastes were proper substrates for bag cultivation. In the effect of different cultivation temperature, $28{\pm}2^{\circ}C$ cultivation temperature was good for for primordial formation after inoculation.

  • The structural stability of a simple-typed cultivation facility with a width of 5.6 m for growing Pleurotus ostreatus was analyzed by modeling the facility as three-dimensional steel frames. The computation was done by using the finite element analysis program, ANSYS and the criterion of determining structural stability was based on the allowable stress design (ASD). The computational results showed that the structure with a straight-typed bed column was more stable than those with other types of bed columns against snow depth but there was little difference against wind velocity. As results, the interval of rafter had a more influence on safety wind velocity than that of bed column, while the interval of bed column was more important to safety snow depth. Finally the bed column against buckling was stable in all cases considered in this paper.

  • During a survey of culturable fungi in Korea, 18 unrecorded fungal species were isolated and identified from the indoor air of mushroom cultivation houses, the materials used for preparation of mushroom cultivation media, wild plants, and funitures. This study reports the descriptions of the 18 unrecorded fungal species: Aspergillus creber, Ceratocystis paradoxa, Colletotrichum spaethianum, Coniochaeta velutina, Coprinellus xanthothrix, Epicoccum sorghinum, Leptosphaeria rubefaciens, Myrothecium gramineum, Paraconiothyrium fuckelii, Penicillium erubescens, Penicillium melinii, Penicillium pulvillorum, Penicillium sabulosum, Penicillium turbatum, Pestalotiopsis portugalica, Pilidiella castaneicola, Rachicladosporium pini, and Umbelopsis nana. For all the identified species, the morphological characteristics including the features of colony formed on media, images of light microscopy, and molecular phylogenetic relationships based on nucleotide sequences of the internal transcribed spacer ribosomal DNA (ITS rDNA), 18S rDNA, 28S rDNA, ${\beta}-tubulin$ gene, calmodulin gene, and translation elongation factor gene were described.

  • This experiments were conducted to study on the economic analysis of Phellinus spp.(Comercial name: Sanghwang mushroom). These results were as follows: Phellinus spp. can be cultivated about 4 years by one time inoculation. This mushroom has been cultivated by the method of burying log into the soil(BM) at the first time. Recently, however, the method of hanging log on the shelves in the house(HM) is used, because HM has more advantage than BM that HM can be cultivated more pieces of logs than BM. On the other hand, HM is required to invest more 5,678,230Won for the equipments than the BM. And also, HM is required 14,400 pieces(2.8 times) more log numbers than BM 5,000 pieces. Also, HM is required more 3,680,000Won to purchase log, 1,104,000Won to purchase spawn. The cost of production is required to 20,180,971Won for BM, and 37,953,825Won for HM. Accordingly, product cost of HM is 1.9 times higher than BM. The operating cost is required to 1,207,712Won for BM, and 24,075,432Won for HM. Accordingly, operating cost of HM is 2.0 times higher than BM. The net income is 580,940,000Won for BM, and 1,683,300,000Won for HM. Accordingly, net income of HM is 2.9 times higher than BM. The income is 589,040,000Won for BM, and 169,718,000Won for HM. Accordingly, income of HM is 2.9 times higher than BM. In conclusion, HM is required 2.8 times more logs. HM has 1.03 times more products per a piece of log. HM has 1.9 times more production cost, and 2.0 times more operating cost. As you read above, HM and BM have two different aspects. BM is required less investment cost than HM, but BM has lower income because of the different capacity of production. By the comparing those two methods, HM is resulted more efficient method for the producing mushroom. Only in the side of cash flowing, the cash expenditure of BM is required less money at first year. But it has no production at first year. BM would get the income after 2 years buring the logs. The cash expenditure of HM is required much money for the equipments and the logs at first year, but HM would get the income at first year.

  • Tricholoma gigantium, an edible mushroom, belongs to Tricholomataceae of Tricholoma and is distributed at Jeju-Do in Korea. It is also well-known as the medicinal mushroom in Taiwan. The cultivation method using the compost was developed in Korea in 1995. To develop a mass cultivation method and a superior strain, four strains were collected and tested. To establish the optimal cultivation conditions, various examinations were accomplished. Bag cultivation was more effective than box cultivation and the optimal relative humidity was more than 80%. Although the mycelial growth was tested in the substrate supplemented with different additives, such as rice bran and wheat bran, there's no significant difference between them. It suggested that the environmental conditions were more important than the substrate additives for cultivation.

  • We designed a system that can automatically collect, convey, and control cool air of $15^{\circ}C-20^{\circ}C$ containing carbon dioxide from a mushroom cultivation house to a strawberry plastic house. We recorded the temperature at various positions from July to August 2017. The average temperature of the green house during day and at night was maintained at $33^{\circ}C$ and $26^{\circ}C$, respectively. In the moveable three-tier cylindrical bed, the average temperature around root was maintained at $26^{\circ}C$ and $21^{\circ}C$ during day and at night, respectively. On the high-bench in the green house, the temperature was maintained at $32^{\circ}C$ and $30^{\circ}C$ during day and at night, respectively. The carbon dioxide concentration was maintained around 800-1,600 ppm in the mushroom cultivation system and 400-800 ppm in the strawberry plastic house. The growth characteristics of the strawberry treated with moveable three-tier cylindrical bed were significantly different from those of the untreated high-bench bed. In addition, during the summer season, moveable three-tier cylindrical bed showed more tendency to increase in normal fruit number (NFN) and to decrease in defective fruit number (DFN) compare to the high-bench bed. Therefore, the moveable three-tier cylindrical bed showed a tendency to be more than 2 times higher yields than that of the high-bench bed. It was confirmed that ever-bearing strawberry cultivars could be cultivated in green house due to the cool air supply from the mushroom cultivation system in the summer season.
