title: [Qualitative and quantitative examinations of bacterial found in aquatic habitats. 4. Communication: Comparison of the bacteria of the water an its layer of scum both derived from a reservoir for drinking water (author's transl)].
abstract: The bacteriological examination of the water from a reservoir and its thin layer of scum (Neuston) showed considerable differences with respect to the colony count and the identified species. The sample from the surface contained 10(6) bacteria per ml. 77% of the isolated species belonged to the genus Pseudomonas. Where as the bacterial count of the water was below 10(3) per ml. In this case gram-negative, oxidase-negative, yellow-pigmented, motile rods belonging to the genus Xanthomonas were isolated most frequently.
