Sažetak
In the environment bacteria mainly exist adhered to solid surfaces in communities known as biofilms. Bacterial biofilm is a sessile community whose cells are attached to the substrate and to each other, engulfed in the matrix of extracellular polymeric substances that they have created. Currently, a five stage model for biofilm development is widely accepted for every biofilm growth, in spite the fact that it was modelled based on biofilm growth in continuous flow conditions. We hypothesize that in static conditions, which are nowadays mostly used for biofilm investigations, the five stage model is perhaps not applicable. So, we used particles of natural zeolite as a unique tool that allows simultaneous visualization and statistically satisfactory quantification of biofilm growth during 24 h. The results from testing two morphologically distinguishable bacterial strains suggested that, when grown in static conditions, five-stage model could be applicable for non-motile bacteria Acinetobacter junii, but not for motile bacteria Bacillus cereus.
