Granulated mixed microbial culture suggesting successful employment of bioaugmentation in the treatment of process wastewaters

Present work gives a review of scientific achievements in the employment of bioaugmentation for degradation of xenobiotics from wastewaters of various origins. The authors point out the role of individual microorganisms and of the mixed culture used as bioaugments for the purpose of bioaugmentation. The study has shown the efficiency of bioaugmentation in wastewater treatment, which led to the development of a new tretament procedure. Being the part of scientific studies on xenobiotics degradation, this work presents the activity of the prepared granulated mixed microbial culture in completedegradation of the surfactant (detergents-LAS) and dyes, based on naphthalenesulfonic acids (6-amino-2-naphthalenesulfonic acid), as the selected representatives of sulphonated aromatic substances. Degradation was performed under alternating oxy/anoxy conditions that contributed to oxido-reductive degradation process of the mentioned substances and, thus, to their complete degradation without generation of degradation intermediates.
