dc.description.abstract | Ibuprofen is one of the most often detected pollutants in the environment, particularly at
landfill sites and in wastewaters. Contamination with pharmaceuticals is often accompanied by the
presence of other compounds which may influence their degradation. This work describes the new
degradation pathway of ibuprofen by Bacillus thuringiensis B1(2015b), focusing on enzymes engaged
in this process. It is known that the key intermediate which transformation limits the velocity of the
degradation process is hydroxyibuprofen. As the degradation rate also depends on various factors,
the influence of selected heavy metals and aromatic compounds on ibuprofen degradation by the
B1(2015b) strain was examined. Based on the values of non-observed effect concentration (NOEC) it
was found that the toxicity of tested metals increases from Hg(II) < Cu(II) < Cd(II) < Co(II) < Cr(VI).
Despite the toxic effect of metals, the biodegradation of ibuprofen was observed. The addition of
Co2+ ions into the medium significantly extended the time necessary for the complete removal of
ibuprofen. It was shown that Bacillus thuringiensis B1(2015b) was able to degrade ibuprofen in the
presence of phenol, benzoate, and 2-chlorophenol. Moreover, along with the removal of ibuprofen,
degradation of phenol and benzoate was observed. Introduction of 4-chlorophenol into the culture
completely inhibits degradation of ibuprofen. | pl_PL |
