[Microbial settlement of paint- and building-materials in the sphere of drinking-water. 2. Information: experimental examination of bitumen paint under working conditions (author's transl)].
A bituminous coating material for drinking water reservoirs was applied on testing plates for a microbial examination. In function of the chlorine content of the water a microbial slime layer could be found on the testing plates. The amount of slime became less in course of the time or was not produced at all, when the plates were desiccated before the experiment for some months. A slime layer could never be observed on plates of asbestos cement and polyacryl as inert materials for comparison. Different microbial populations were observed.
