Filaments PLUS

Specific identification and population profile generation
of all problematic filamentous bacteria

Item Number: 01120003

Lab analysis: detection of all filamentous bacteria

Your sample will be analyzed by a large number of group- and species-specific gene probes for filamentous bacteria in wastewater samples. Results are displayed as percental shares on the complete viable flora. In combination with the measured total cell count (living and dead) the filamentous bacteria are exactly profiled in the wastewater sample. Even unknown filaments are typified.

Results are displayed as percental shares on the complete viable flora. The report contains a representative photo documentation that visualizes the filamentous bacteria in the sample.

You will find a detailed description in our article dealing with filaments in activated sludge.
