Relative quantitation of accumulations of ectoine and hydroxyectoine at different concentrations of NaCl by HPLC.
Solid squares (■), pright triangles (▲), inverse triangles (▼), diamonds (♦) and black circles (•) indicate Streptomyces strains from Qijiaojing (QJJ) and Aydingkol (AK) salt lake sites in Xinjiang Province and Jiangcheng (JC), Heijing (HJ), Yunlong(YL) salt mine sites in Yunnan Province, respectively. For estimating fold changes in accumulation of ectoine and hydroxyectoine, 1 fold changes was defined as the accumulation of ectoine and hydroxyectoine in Streptomyces cells that were grown at the ISP3 medium without salt (0% g/ml of NaCl), each deviation of fold changes was calculated by comparing quantitation of ectoine and hydroxyectoine in Streptomyces cells growing at salt treated ISP3 medium (5% and 15% g/ml of NaCl) with normal (0% g/ml of NaCl) medium.
