Abstract
Products made from plastic material are commonly found in our life. Polystyrene is a type of plastic synthesises. In the nature, polystyrene is known to be recalcitrant due to its complex structural molecule. Number of studies reported that the existence of polystyrene plastic presents various threats for sea animals such as zebra fish, sea urchin^s early development gene, and lowered crustaceans^ life expectancy. This literature study was conducted by collecting various information on polystyrene pollution in the environment and the ability of Pseudomonas aeruginosa bacteria to degrade polystyrene. Pseudomonas aeruginosa (1 x 108 cell/ml) bacteria was cultured in 25 ml liquid carbon-free basal medium and 1 gram polystyrene on 25oC temperature for 15 days. The result shows that the compound was able to degrade 0.098% of polystyrene per day with yield constant of 1,111,111.11. This literature study will be continued on pilot scale by conducting experiment of polystyrene biodegradation on an area that is previously added with liquid carbon-free basal medium by land treatment method with dimensional size of 3m x 1.5m x 0.3m with additional 1.35 m3 LFCBM (liquid carbon-free basal medium).
