A variety of abiotic stresses limit plant growth and crop productivity. Among the abiotic stress, salinity is one of the major harmful stresses to plants. Plant growth-promoting bacterium was isolated from reclaimed land soil of Kyehwa-do and identified as Pseudomonas. Pseudomonas sp. strain G19 produced 7.5 µg/ml of indole acetic acid and solubilized 25% of insoluble phosphate after 36 h cultivation. Also, G19 was able to produce a protein that was structurally homologous to 1-aminocyclopropane-1-carboxylate deaminase of Pseudomonas fluorescens KACC10070 playing a role in reduction of ethylene in plant. The strain G19 increased the biomass of Chinese cabbage seedlings grown in the presence of 150 mM NaCl. The results indicated that the strain G19 promoted the growth of Chinese cabbage seedling under salinity stress through microbe-plant interactions. 염 내성 미생물 선발을 위해 계화도 간척지의 토양 1 g을 채취 하여 0.8% NaCl 용액으로 연속 희석한 후, Pikovskaya's 배지 (0.05% yeast extract, 1% glucose, 0.5% calcium phosphate, 0.05% ammonium sulphate, 0.02% potassium chloride, 0.01% magnesium sulphate 0.00001% manganese sulphate, 0.00001%
