【摘要】 从大连普兰店盐场盐池土壤中分离到一株产渗透压补偿溶质Ectoine的菌株DL031,通过16SrDNA序列分析,菌株DL031与Halomonas marina相似性为99%.菌株DL031可在含有0～200 g/LNaCl培养基中生长,生长最适NaCl浓度为100 g/L.DL031菌株在含有NaCl的培养基中诱导能合成Ectoine;在含3 mol/L NaCl的培养基,30℃诱导培养48 h,Ectoine的合成量为98.8 mg/L.更多还原

【Abstract】 DL031 was isolated from salt field in Pu Landian.Its 16S rDNA sequence is 99% homologious to that of Halomonas marina.DL031 was capable of growing in the medium containing 0-200 g/L NaCl,in which the optimum NaCl was 100 g/L.When DL031 was cultivated in the medium with 3 mol/L NaCl for 48 h at 30 ℃,the Ectoine concentration was 98.8 mg/L.更多还原
