느타리버섯 종균을 배양 후 저장온도와 저장기간에 따른 잡균오염을, 배양적 특성 및 생산성을 조사하였다. 종균의 잡균오염율은 저온저장은 90일까지 0%였으며 상온저장은 60일에 6.3%였으며 120일에는 86.5%로 증가하였다. 저장 종균을 병재배용 배지에 접종하여 병재배 하였던 바, 균사 배양일수는 상온저장 종균은 $21{sim}26$일로 저장기간이 길수록 길었으며, 저온 저장종균은 $21{sim}22$일로 별 차이가 없었다. 저장 종균의 초발이 소요일수는 저장 기간이 길수록 길었으며, 저온저장 종균이 상온 저장 종균보다 $1{sim}2$일... -

from indoor air sampling of cultivation houses used for oak wood mushroom using sawdust media. Among the obtained isolates, 248 isolates were identified as Trichoderma fungi including T. harzianum, T. atroviride, T. citrinoviride, and T. pseudokoningii, by morphological and molecular analysis. T. harzianum was dominant among the four identified species. All the four Trichoderma species grew fast on solid nutrient media tested (potato dextrose agar [PDA], malt extract agar [MEA], Czapek’s Dox +... -
Characterization of the rcsA Gene from Pantoea sp. Strain PPE7 and Its Influence on Extracellular Polysaccharide Production and Virulence on Pleurotus eryngii

RcsA is a positive activator of extracellular polysaccharide (EPS) synthesis in the Enterobacteriaceae. The rcsA gene of the soft rot pathogen Pantoea sp. strain PPE7 in Pleurotus eryngii was cloned by PCR amplification, and its role in EPS synthesis and virulence was investigated. The RcsA protein contains 3 highly conserved domains, and the C-terminal end of the open reading frame shared significant amino acid homology to the helix-turn-helix DNA binding motif of bacterial activator proteins.... -
Defense Response and Suppression of Phytophthora Blight Disease of Pepper by Water Extract from Spent Mushroom Substrate of Lentinula edodes

한국식물병리학회 The Plant Pathology Journal 2017, 33권 3호 5 264-275 (12 pages)
of Lentinula edodes that was derived from sawdust bag cultivation was used as materials for controlling Phytophthora blight disease of pepper. Water extract from SMS (WESMS) of L. edodes inhibited mycelial growth of Phytophthora capsici, suppressed Phytophthora blight disease of pepper seedlings by 65% and promoted growth of the plant over 30%. In high performance liquid chromatography (HPLC) analysis, oxalic acid was detected as the main organic acid compound in WESMS and inhibited the fungal... -
Note : Open Access ; Occurrence of dsRNA Mycovirus (LeV-FMRI0339) in the Edible Mushroom Lentinula edodes and Meiotic Stability of LeV-FMRI0339 among Monokaryotic Progeny

dsRNA was found in malformed cultures of Lentinula edodes strain FMRI0339, one of the three most popular sawdust cultivated commercial strains of shiitake, and was also found in healthy-looking fruiting bodies and actively growing mycelia. Cloning of the partial genome of the dsRNA revealed the presence of the RdRp sequence of a novel L. edodes mycovirus (LeV), and sequence comparison of the cloned amplicon showed identical sequences sequence to known RNA-dependent RNA polymerase genes of LeV... -
Roles of Ascospores and Arthroconidia of Xylogone ganodermophthora in Development of Yellow Rot in Cultivated Mushroom, Ganoderma lucidum
한국식물병리학회 The Plant Pathology Journal 10 Pages
한국식물병리학회 The Plant Pathology Journal 2011, 27권 2호 6 138-147 (10 pages)
Xylogone ganodermophthora, an ascomycetous fungus, is known to cause yellow rot in the cultivated mushroom Ganoderma lucidum. In this study, we investigated the dissemination of this fungal pathogen in G. lucidum grown in cultivation houses. To determine the role of ascospores produced by X. ganodermophthora in disease development, we constructed a green fluorescent proteinlabeled transgenic strain. This X. ganodermophthora strain produced a number of ascomata in the tissues of oak logs on which... -

본 연구는 버들송이버섯의 균사 생육 최적조건을 구명하여 액체종균을 제조하고 또한 톱밥종균의 영양원을 선발하기위하여 시험을 수행하였고, 선발된 종균에 대한 종균 접종량을 설정하여 병재배에 적합한 조건을 구명하고자 하였다. 버들송이버섯의 톱밥종균은 미송톱밥(70%)+밀기울(30%)의 비율, 포플러톱밥(80%)+옥수수가루(20%) 조건으로 배합할 때 균사 생육이 양호하였다. 액체종균에 대한 영양원 선발 및 첨가량은 백설탕 1.0~1.5%, yeast extract $0.7g/{ell}$, 콩가루 $0.17g/{ell}$, 무기물은 $MgSO_4{cdot}7H_2O;0.3g/{ell}$,... -

종균의 종류에 따라 중온성 품종의 생산성이 어떻게 달라지는지를 확인하고자 연구를 수행하였다. 버섯의 발생 경향은 세 처리구 모두 비슷했으며, 성형종균과 액체종균 처리구는 2차발생까지 총수확량의 50% 이상, 4차까지 80%이상 발생되었다. 기형버섯조사에서는, 세 처리구 모두 2차 발생까지만 기형버섯이 발생되었다. 하지만 기형버섯 발생률에 있어서는 다른 처리구들에 비해 액체종균 접종구에서의 발생률이 낮았다. 수확량조사에서는 액체종균을 접종했을 때 배지당 411 g으로 처리구들 중 가장 많았고 10 g이 넘는 버섯도 309...
