Sažetak
In recent years, there has been a growing awareness of the negative impact of medicines on the environment. Pharmaceutical products enter the environment at all stages of production, for example through the waste streams of the pharmaceutical industry and as household waste. The biggest problem is the release of antibiotics into the environment, because pathogenic organisms develop resistance to these drugs, so it is difficult to treat them. Such compounds contribute to atmospheric, hydrosphere and lithosphere pollution and undergo various transformations, often producing even more toxic compounds that can negatively affect flora, fauna and humans. Biodegradation is one of the effective degradation processes that uses biological activity to solve such problems and is carried out with the help of indigenous and exogenous microorganisms. The basis of this process is that some microorganisms have the ability to use organic pollutants as a source of nutrients for their growth and development in order to detoxify, mineralize or transform such compounds. In this work, the removal of the pharmaceutical antibiotic amoxicillin by the process of biodegradation was carried out using bacterium Pseudomonas aeruginosa under batch conditions for 12 days. The experiment was conducted in two parallel reactors with initial amoxicillin concentrations of 278 mg/L (Pa-1) and 658 mg/L (Pa-2). During the experiment, the change in amoxicillin concentration was monitored. The results show a process efficiency of 49.6 and 36.2% for Pa-1 and Pa-2, respectively.
