实验于高温碱性下筛选得到一株能够代谢硫代硫酸钠( Na2 S2 O3)的革兰氏阴性短杆菌,命名为GDC-2。通过单因素实验,得到其最适生长条件:温度为45℃、pH值为8.5,摇床转速为150 r/min。在最适条件下,测定了该菌的生长曲线,知其世代时间为20 h;在此条件下,该菌经13 h使得溶液中Na2S2O3的含量减少了1.35 g/L(脱硫率21.19%),研究结果将为工业脱硫副产物Na2S2O3的降解提供参考。

A thermophilic alkaline desulphuricant bacterium , which was named as GDC -2, was isolated and could metabolize sodium thiosulfate .The bacterium was short rod -shaped and Gram negative .The single factor tests were carried out and the optimum culture condition was confirmed as follows : the temperature was presented at 45℃, the pH was displayed at 8.8, and the stirring speed of the shaker was observed at 150 r/min. Under the optimum culture condition , the cells of the strain can live for 20 h.After the regeneration of the above desulfurization solution under help of the strain cells , the concentration of sodium thiosulfate was decreased by 1.35 g/L ( percentage loss of content 21.19 %).These results suggest that the strain has potential application to the regeneration of industrial solution containing sodium thiosulfate .
