Abstract
The quantification of the intracellular concentration of ectoine in Virgibacillus pantothenticus revealed that the production of this compatible solute is triggered either by an increase in the external salinity or by a reduction in the growth temperature. This finding reflects increased transcription of the ectoine biosynthetic operon (ectABC) under both environmental conditions.
摘要
对泛菌属嗜盐芽孢杆菌胞内依克多因浓度的定量分析表明，这种相容性溶质的产生要么是由外部盐度的增加引发，要么是由生长温度的降低引发。这一发现反映了在这两种环境条件下依克多因生物合成操纵子（ectABC）转录的增加。
