gelatin liquefaction

Conclusion Gelatin liquefaction tests performed by charcoal powder gelatin microtube methods can get result rapidly and clearly, and can save reagents.

结论采用炭末明胶微量管进行明胶液化试验反应快，结果明了便于观察，试剂用量少，体积小且能室温长期保存，优于营养明胶法，X线胶片法和常量炭末明胶法。

The average days of gelatin liquefaction were 3.3 days with nutrition gelatin method, 2.5 days with routine charcoal powder gelatin method and 1.5 days with charcoal powder gelatin microtube method.

明胶液化平均天数，营养明胶法3.3d，常量炭末明胶法2.5d，而炭末明胶微量管法仅为1.5d。

Methods Gelatin liquefaction tests were performed on 145 strains of 31 species of bacteria with the nutrition gelatin method, x-ray film method, routine charcoal powder gelatin and charcoal powder gelatin microtube method, the results of each method were compared.

方法对31种、145株细菌，采用营养明胶法、X线胶片法、常量炭末明胶法及炭末明胶微量管法进行明胶液化试验，并进行对比。
