§ 78. Mr. Doddsasked the Under-Secretary of State for the Home Department, as representing the Lord President of the Council, where the supplies of bacteria used in the sulphur-producing experiments by the Department of Industrial and Scientific Research are obtained.
§ Mr. de FreitasThey are found in soils and natural waters in many parts of the world—including France, Holland, Italy, Persia, Libya, South Africa, the United States, Venezuela, and from near the hon. Member's own constituency in Kent. The strains of bacteria which are most effective in producing sulphur have been isolated in a pure state and cultures of these are kept at the Chemical Research Laboratory. As further quantities are needed they can be bred from these.
