Opis:: Materials like polyvinyl chloride (PVC), polypropylene (PP), ultra high molecular weight polyethylene (UHMW-PE) are used for the construction of drinking water supply systems. It was found that regardless of the type of material the distribution network is built of, microorganisms formed biofilms on every available surface. The pipes material plays a key role in terms of biofilm formation. Important factors are the surface roughness, adhesives, plasticizers, stabilizers, which can be a source of nutrients for bacteria. The metabolic activity of microorganisms on polymer materials, induces migration of compounds from the material into water. The aim of this study was to present the differences in the structure and the metabolic profile of biofilm formed on the technical materials.

Opis:: Microorganisms in the drinking water distribution system form a biofilm on the inner surfaces of the pipes. It is a life preserving strategy that provides easier access to nutrients and protects against harmful environmental factors. The biofilm is a habitat for numerous species of autochthonous microflora which contribute to the intensification of bio-corrosion and negatively affect the quality of the water supplied to the consumers. Additionally, the biofilm can consist of pathogenic species, which may pose an epidemiological hazard. Every drinking water distribution system has its own microflora, it is associated with the presence of autochthonous microorganisms that come from the raw water which despite treatment processes leaked to the network, and microbes that entered as a result of maintenance, failures and leakages. These factors contribute to the biofilm uniqueness in each water supply system, it is associated with the lack of reproducibility of the structure. In the present study characterized the microorganisms from biofilm of 17 tapping points of the water supply system for their ability to adhesion, resistance against selected antibiotics and rated their enzymatic activity. It is believed that the microorganisms with high surface affinity can play a decisive role in the early stages of biofilm formation.
