Phanerochaete chrysosporium의 액체 배양 및 Lignin Peroxidase 생산
박세근,정명선,김영관 江原大學校 産業技術硏究所 2001 産業技術硏究 Vol.21 No.A
This study characterizes the growth of white rot fungi Phanerochaete chrysosporium IFO 31249 and lignin peroxidase(LiP) activity in different submerged culture media. P. chrysosporium was grown in the form of pellet of various sizes from a spore inoculum under shaking liquid culture condition. While the growth of mycelia was higher under the nitrogen-sufficient culture than under the nitrogen-limited culture, ligninase activity was relatively lower. The lignin peroxidase appeared in nitrogen-limited culture and was suppressed by excess nitrogen. High level(40U/l) of lignin peroxidase activity was obtained in the growth medium containing 1.5mM veratryl alcohol, a secondary metabolite of P. chrysosporium. Lignin peroxidase production was not observed under conditions of nitrogen sufficiency or in balanced media, suggesting that control parameters could increase the activity by manipulating the secondary metabolism.

서로 특성이 다양한 32개의 도입한 Alfalfa품종을 우리나라 중부지역인 충청남도에 재배하여 초장과 건물중 등의 생육상태를 비교, 검토한 결과는 다음과 같다. 1. 평균초장이 큰 상위 10개 품종들은 Dekalb brand 135 > Diamond > Pioneer brand 581 > Raidor > Pioneer brand532 > Pierce> Nitro > Sparta ) Florida 77 > Sapphire의 품종순 이 며, 초장이 작은 10개 품종을 최하위 순으로 열거하여 보면 Salute < Spredor 2 < LS-1920 < Arrow < Challenger < Milkmaker < Armor < Pioneer brand 545 < Pioneer brand 5262 < Saranac의 품종 순이였다. 2. 총건물 수량이 많은 상위 10개 품종들은 Diamond > Nitro > Dekalb brand 120 > Dekalb brand 135 > Drummer > Saranac > Sapphire > Raider > Magnum > Dekalb brand 167의 품종 순이며, 건물수량이 적은 최하위 순으로 10개 품종은 Milkmaker < Pioneer brand 526 < Pioneer brand 5262 < Salute < Pioneer brand 555 < Decathlon < Pioneer brand 5929 < LS-1920 < Pioneer brand 581 < Husky의 품종들이였다. 3 평균초장과 총건물 수량의 결과를 비교하여 보면 대체로 초장이 우세하였거나, 열세하였던 품 종들이 다소간 건물수량이 우세하거나 열세하였으며, 정비례한 결과는 보이지 아니하였다. 4. 생육상태 및 건물수량이 모두 좋은 품종들은 Diamond, Nitro, Dekalb brand 135, Sapphire, Raidor품종들이며, 우리나라 중서부지역의 재배환경에 적합한 품종으로 사료된다 This study was conducted to select the best adapted alfalfa cultivars among the 32 introduced alfalfa cultivars with different characteristics in Chung-Chong Nam Do, Korea, environmental condition. Mean of plant height and total dry matter yields per cultivar from May to August in 1996 were determined. On the point of mean of plant height, ten high ranked cultivars among the 32 alfalfa cultivars in high order were Dekalb brand 135>Diamond>Pioneer brand 581>Raidor>Pioneer brand 532>Pierce>Nitro>Sparta>Florida 77>Sapphire and ten low ranked cultivars in low order were Salute<Spredor 2<LS-1920<Arrow<Challenger<Milkmaker<Armor<Pioneer brand 545<Pioneer brand 5262<Saranac. Ten high ranked cultivars from 32 alfalfa cultivars on the total dry matter yields in high order were Diamond>Nitro>Dekalb brand 120>Dekalb brand 135>Drummor>Saranac>Sapphire>Raidor>Magnum>Dekalb brand 167 and ten low ranked cultivars in low order were Milkmaker<Pioneer brand 526<Pioneer brand 5262<Salute<Pioneer brand 555<Decathlon<Pioneer brand 5929<LS-1920<Pioneer brand 581<Husky. Total dry matter yields of per cultivar was also slightly greater but It was not appeared direct proportion when alfalfa cultivar was appeared higher mean of plant height compared with those which were lower mean of plant height. Leading alfalfa cultivars for plant growth and dry matter yields were Diamond, Nitro, Dekalb brand 135, Sapphire, Raidor cultivar which can be well grown under moderate temperatures zone of midwest in Korea.

Systemic sclerosis is an autoimmune rheumatic disease of unknown etiology, often manifested with excessive, fibrosis of the skin. The viscous properties of the skin are impaired, and the main histologic changes include a thicker dermis, absence of pilosebaceous units, and a decreased space between collagen bundles. We present a case of 20-year- old Korean woman with micrognathia and microchilia due to systemic sclerosis who came for improvement of her doll-like appearance. We saw an improvement in her micrognathia and microchilia by using Restylane(R) and Perlane(R). (Korean J Dermatol 2007;45(6):632∼634)

A congenital ectopic nail is a rare anomaly and usually manifests itself as a small abnormal nail appearing alongside the normal nail. In most of the cases, abnormal nails have been found on the palmar surface of the fifth finger. The pathogenesis of the ectopic nail remains unclear. It has been postulated to be a kind of polydactyly or generation from stray germ cell or inoculation of the nail matrix after trauma. We observed a case of a 5-month-old boy with congenital ectopic toenail on the right second toe. The ectopic toenail was removed by surgical excision and the histopathological finding was consistent with ectopic toenail. We report a case of congenital ectopic toenail on the right second toe of a 5-month-old boy. (Korean J Dermatol 2008;46(1):106∼108)
