TESTS FOR BACTERIA AS CAUSES OF DETERIORATION

The Professor of Bacteriology at the Kansas Agricultural Experimental station gives here a survey of the modes of action of specified bacteria in causing materials breakdown, with particular reference to pipe coatings, and also covers the test procedures used and the reasons for their selection. The article contains the main substance of a paper published recently by Kansas State University, Manhattan, Kansas; the latter is closely associated with large‐scale projects in the investigation of underground corrosion.
