Isolation of polystyrene foam biodegradable bacteria from petrol contaminated soil

Researcher : Pat Pataranutaporn Advisor : Dr.Opas Tuntithagoon and Dr.Ampaithip Sukghom Co-Advisor : Rattanawan Inpang

Abstract 01 The purpose of this study was to isolate polystyrene foam biodegradable bacteria from petrol contaminated soil. Mineral salt medium with polystyrene foam as the only carbon source was used in this experiment. After 4 months of incubation, surface of polystyrene foam was observed compared with the control group. The result showed that there were some traces of degradation on the surface of polystyrene foam when compared to the control group which the same source of soil was used as inoculum but had been sterilized before inoculation. Twenty-four isolates of Gram-positive bacteria were isolated from polystyrene foam degraded flasks, 19 isolates were bacilli and 5 were cocci shape.

Introduction 02 Polystyrene foam is a type of plastic produced from styrene. It is a lightweight, moisture-resistant material with exceptional insulation properties. Products made from foamed polystyrene are nearly ubiquitous, for example packing materials, insulation, and foam drink cups. Polystyrene takes hundreds of years to decompose and is often abundant as a form of pollution in the outdoor environment.

Methodology 03 Methodology. Soil samples were collected from sources that were contaminated by petrol. One gram of contaminated soil sample was inoculated into 100 ml of Mineral salt medium (K2HPO4, 2.0g; KH2PO4, 0.2g; (NH4)2SO4, 0.5g; MgSO4, 0.05g; EDTA, 0.5mg; FeSO4.2H2O, 0.25mg; MnCl2.4H2O, 0.003mg; CoCl2.6H2O, 0.012mg; CuCl2.2H2O, 0.001mg; NiCl2.6H2O, 0.002mg; Na2MoO4.2H2O, 0.003mg; ZnSO4.7H2O, 0.008mg, H3BO3, 0.02mg with 1000 ml distilled water, pH 7.3) in 250 ml flask. Small pieces of 0.1 g of polystyrene foam were added as carbon source. Prior to use, polystyrene foam was soaked in 70% alcohol and washed two times with distilled water and dried in desiccator for two days. In the control group, 1 gram of sterilized petrol contaminated soil sample was used. All experiment was carried out in triplicate. All flasks were incubated in shaker at 150 rpm, 30oC for 2 months. After 2 months of incubation 1 ml of cell suspension was inoculated into a new flask and incubated in the same condition for 2 months. Surface of polystyrene foam was observed under stereo zoom microscope and taken photograph. Culture broth was diluted and spread onto glucose yeast extract agar (4 gram of glucose and yeast extract in 1,000 ml of distilled water, pH 7.3) and incubated at 30oC for two weeks, colonies of bacteria were picked, purified and morphological studied by Gram-staining and observed under microscope.

Result and discussion 04 The results showed that bacteria from petrol contaminated soil could grow in mineral medium that polystyrene foam was the only carbon source and 24 isolates of Gram-positive bacteria were isolated; 19 isolates were rod and 5 isolates were round shape. Furthermore, some traces of degradation were found on the surface of polystyrene foam from the experiment flasks rather than the control group. These results indicated that there are polystyrene foam degradable bacteria from petrol contaminated soil and It might use polystyrene foam as carbon and energy sources. However, further investigation need to be done for confirmation the results of these experiments and that is our future study.
