Abstract

For the detection and quantitative determination of nitrosomonas strains in wastewaters and soils, a gene probe is used which, by virtue of its complementary sequences, only hybridizes with parts of the genome of nitrosomonas strains from wastewater or soil samples and does not produce a positive hybridization signal with parts of the genome of other bacteria and the hybridized nucleic acid is quantitatively determined by means of a known label of the gene probe and thus provides a direct measure of the content of nitrosomonas strains in the wastewater or soil sample.
