DETERMINATION OF OPTIMAL CONDITIONS FOR BIODEGRADATION OF POLYSTYRENE BY BACTERIA

Microplastic particles at size lower than 5 mm represent global environmental problem according to their long lasting in the environment and impact on aquatic organisms through bioaccumulation and biomagnifications. Due to this, further researches are focused at finding adequate solutions for its removal from the environment. Potential solutions are biological processes, e.g. bioremediation, as an economical, efficient and environmentally friendly process, which involves the use of microorganisms in the purpose of removing pollutants from the environment. In this study, biodegradation of polystyrene (PS) by two bacteria Bacillus cereus and Pseudomonas alcaligenes was investigated. Firstly, crucial factors that influence on biodegradation of PS were performed according to Taguchi design. During 30 days of experiments, 7 factors at 2 levels were investigated. According to the first set of experiments, optimal biodegradation conditions were determinate by Full Factorial design. In order to analyze influence of the examined factors, RSM methodology was applied. The number of living bacterial cells was used as response parameters. However, the aim of this study was to examine the possibility of biodegradation of microplastics by bacteria isolated from microplastic-enriched environmental samples. The use of environmental bacteria for biodegradation of microplastics, the determination of significant factors influencing the biodegradation process and the determination of optimal conditions for biodegradation are innovations of this research. This paper scientifically contributes to the expansion of existing knowledge about microplastics, since the removal of microplastics from surface systems by bacteria has been studied.
