嗜热厌氧杆菌X514的盐度和pH生长范围研究

Study of Growth Range of pH and Salinity for Thermoanaerobacter sp. X514

[目的]研究嗜热厌氧杆菌X514的盐度及pH生长范围。[方法]设置不同Nacl浓度梯度及pH范围,分别将X514在不同盐度及起始pH培养基中培养,测定不同时段下X514的生长情况。[结果]X514的最适生长盐度为0 g/L,最适生长pH范围为pH 7~9。[结论]X514的生长受盐度影响明显,其最适生长pH范围与其他嗜热厌氧菌相似。

[Objective] The growth range of salinity and pH for thermoanaerobacter sp were researched.[Methods] X514 were cultured in different culture mediums which contained multiple gradient salinities and initial pH,and then the growth ranges of X514 were determined.[Results] The optimum growth salinity of X514 was 0 g/L,and the best pH range was pH 7-9.[Conclusion] Salinity had significant effect on the growth of X514,the best pH range of X514 were as the same as other thermoanaerobacter.
