Abstract

Several methods of determining tellurium reduced by and deposited in the cells of Gram-negative bacteria are analysed and evaluated. In a series of techniques elaborated by the author, the most satisfactory was found to be the lysis of cells containing tellurium by boiling in sodium laurylsulphate. The resultant colloidal tellurium solution is black-brown, with maximum absorption at wavelength 280 mμ. The method is simple, rapid and sensitive.

Abstract

Рассматривается и оценивается несколько способов определения теллура в клетках грам-отрицательных бактерий. Из целого ряда разработанных автором приемов лучше других оправдало себя разрушение клеток, содержащих теллур, лаурилсулыьатом натрия при кипячении. Возникающий таким образом коллоидный раствор теллура, чернокоричневого цвета, дает максимум абсорбции при длине волны 280 мμ. Это простой, быстрой и чувствительный метод.
