Sažetak
Acinetobacter baumannii is an emerging human pathogen. Antibiotics-resistant A. baumannii disseminate via the untreated hospital sewage to urban wastewaters and nature, which represent the public health concern. Here we tested the natural zeolitizied tuff (NZ) as a material for the capture of pandrug-resistant A. baumannii from nutrient-poor and nutrient-rich water. According to the behaviour of bacteria in two different water media, the mode of A. baumannii immobilization onto NZ is proposed. Planktonic cells of A. baumannii present in water became quickly attached onto the surface of NZ particles, regardless of the nutrient concentration in water. Immobilized cells excrete the extracellular polymeric substances and form stabile biofilm on the particles within 24h. No further incorporation of planktonic cells occurs in the formed biofilm. In the nutrient-poor water the shortage of nutrients prevents the multiplication of bacteria previously incorporated in the biofilm, and consequently biofilm stays conserved. In the nutrient-rich water the availability of nutrients enables the multiplication of bacteria inside the initially formed biofilm, which results in the increase of bacterial number and further maturation of biofilm. The NZ is efficient in removal of A. baumannii from nutrient-poor and nutrient-rich waters.
