inulin을 기질로 하여 중합도가 큰 oligo당으로 가수분해하는 새로운 endo형 Inulinase 생산균주로, Arthrobacter sp. S37를 분리, 선발하였다. 본 효소의 생산은 inulin과 돼지감자 추출물에 의해 유도되었으며, 탄소원으로 1.5% 돼지감자 추출물, 유기질소원으로 1.0% yeast extract, 무기 질소원으로 0.5% $NaNO_3$를 사용하였을 때 효소 생산이 가장 많았다. 또한 최적 배양 pH와 온도는 각각 pH 8.0과 $30^{circ}C$로 나타났다. 최적 배지와 최적 배양 조건하에서 배양한 결과 배양 24시간에 10.8 units/ml로 최대효소생산을 보였다. -

나타났다. 근권과 근면에서 분리된 EPS 세균 중 Arthrobacter 속에 속하는 균주는 가장 특징적인 세균으로 밝혀졌으며, Rhizobium 속은 근내부에서 분리된 가장 특징적인 EPS 생성세균으로 나타났다. EPS 생성 우수균주 Rhizobium sp. 1NP2 (KACC 17637)는 10 g/L 그리고 Arthrobacter sp. 5MP1 (KACC 17636)는 4.9 g/L의 다당을 생성하였으며, 당단백질의 구성당 성분을 확인한 결과, galactose, glucose, mannose를 구성하고 있었으며, glucosamine의 아미노당이 나타났다. 특히, glucose는 72.7-84.9%로 주요 구성당임이 확인되었다. -
Effect of Bacillus aryabhattai H26-2 and B. siamensis H30-3 on Growth Promotion and Alleviation of Heat and Drought Stresses in Chinese Cabbage

Plants are exposed to biotic stresses caused by pathogen attack and complex abiotic stresses including heat and drought by dynamic climate changes. To alleviate these stresses, we investigated two bacterial stains, H26-2 and H30-3 in two cultivars (‘Ryeokkwang’ and ‘Buram-3-ho’) of Chinese cabbage in plastic pots in a greenhouse. We evaluated effects of bacterial strains on plant growth-promotion and mitigation of heat and drought stresses; the role of exopolysaccharides as one of bacterial... -
Growth Promoting Rhizospheric and Endophytic Bacteria from Curcuma longa L. as Biocontrol Agents against Rhizome Rot and Leaf Blight Diseases

Plant growth promoting rhizobacteria and endophytic bacteria were isolated from different varieties of turmeric (Curcuma longa L.) from South India. Totally 50 strains representing, 30 PGPR and 20 endophytic bacteria were identified based on biochemical assays and 16S rDNA sequence analysis. The isolates were screened for antagonistic activity against Pythium aphanidermatum (Edson) Fitzp., and Rhizoctonia solani Kuhn., causing rhizome rot and leaf blight diseases in turmeric, by dual culture and... -
Biological Control of Bacterial Fruit Blotch of Watermelon Pathogen (Acidovorax citrulli) with Rhizosphere Associated Bacteria

한국식물병리학회 The Plant Pathology Journal 2017, 33권 2호 9 170-183 (14 pages)
Bacterial fruit blotch (BFB), which is caused by Acidovorax citrulli, is a serious threat to watermelon growers around the world. The present study was conducted to screen effective rhizobacterial isolates against 35 different A. citrulli isolates and determine their efficacy on BFB and growth parameters of watermelon. Two rhizobacterial isolates viz. Paenibacillus polymyxa (SN-22), Sinomonas atrocyanea (NSB-27) showed high inhibitory activity in the preliminary screening and were further... -

as members of genera Bacillus, Streptomyces, Arthrobacter, Pseudomonas and Mesorhizobium. All tested isolates were capable to degrade both synthetic and natural NAHL produced by Pectobacterium carotovorum subsp. carotovorum (Pcc) strain EMPCC. In quorum quenching experiments selected isolates, especially Mesorhizobium sp., were markedly reduced the pathogenicity of Pcc strain EMPCC in potato tubers and totally suppressed tissue maceration on potato tubers. These led to consider the latter as a... -
