Sažetak
Microplastics are considered as particles lower than 5 mm and are ubiquitous in the environment. [1] Due to the fact that microplastics are present in the environment, different effects on aquatic organisms may occur. Accordingly, ecotoxicological studies are perfomed with various testing organisms such as algae, Daphnia magna, Danio rerio, fishes etc. [1] However, a lot of processes, physical, chemical and biological, have been investigated in the purpose to remove the microplastics from the environment. [2] Bioremediation is environmentally acceptable and economical treatment that can be used in the mentioned purposes. In this study, biodegradation of polystyrene (PS) and polyvinyl chloride (PVC) by bacteria Bacillus cereus and Pseudomonas alcaligenes were investigated. Experiments were performed according to Taguchi design. The influence of seven factors - pH-value, temperature, size of microplastic particles, concentration of microplastics, agitation speed, optical density of bacterial suspension, and addition of glucose, were examined. According to the CFU values, higher biodegradation rate was noticed for B. cereus in comparison with P. alcaligenes.
