- Abstract
The biofilms have major negative effects in different science domains, with multiple implications in microbiology, medicine, industry, materials engineering etc. The purpose of this paper is to observe the formation of bacterial biofilms in seawater, to determine the density of bacterial cells during the formation of the biofilms and observe temporal dynamics on artificial surfaces. The experimental system was represented by the three bioreactors used to recreate the dynamic conditions and artificial hydrophobe and hydrophile surfaces. Only three days after the immersion of the artificial substrate, a dense layer of cells is formed on the surfaces of glass and 15-18 days later, depending on the thickness of the biofilm, detachment and dispersion phenomena occur. The formation of biofilms dynamic conditions occurs more slowly the density values are between 10∙ 103 cel/mm2 and 25∙103 cel/mm2 , because the speed of water recirculation is a limiting factor for adherent bacteria.
