    The effect of cell adhesion ON POLlUTANT biodegradation

  • Original language description

    The unicellular microorganisms naturally form multicellular communities which differentiate into specialize cells that bring a benefit to whole population. Predominant multicultural form of bacteria is called biofilm. Bacterial biofilms are generally described as surface associated community consisting of microcolonies surrounded by a matrix of exopolymers with varied composition. The characteristics of biofilm which are in focus of present research are the ability to withstand and degrade high concentration of various toxic substances. Gram-positive Rhodococcus erythropolis was chosen for our experiments. Bacteria were cultivated in mineral medium under different cultivation conditions. A several toxic substances were used as a sole carbon source (e.g.: phenol, aniline, catechol). The ability of bacterial cell to adhere on different polymer materials was tested by several methods: colorimetric method (staining and distaining of sessile cells with crystal violet), microscopic observati

    Vliv buněčné adheze na biodegradaci polutantů

  • Czech description

    Cílem této práce bylo stanovení vlivu buněčné adheze na biodegradaci toxických sloučenin (fenol, anilin, katechol). Míra buněčné adheze na materiály s rozdílnou hydrofobitou (sklo a silikon) byla sledována metodou analýzy obrazu. Koncentrace toxické sloučeniny v médiu byla sledována metodou HPLC. Byly porovnány rychlosti degradace toxických látek susupenzními buňkami a buňkami připoutanými na silikonový či skleněný nosič. Bylo zjištěno, že ačkoli buňky Rhodococcus erythropolis lépe kolonizují silikonovýnosič, nejvyšší biodegradační rychlosti bylo dosaženo v systému se skleněným nosičem. Naše výsledky potvrdily předpoklad vyšší odolnosti biofilmu vůči toxickým látkám a schopnost rychlejší degradace těchto látek.
