Abstract

The aim of this study was to investigate the plant-microbe interaction of Serratia marcescens isolates in phytoremediation of gasoline contaminated soil using plant bulrush of Scirpus mucronatus. The experiment included control plant and three phytoremediation treatments, with gasoline as a hydrocarbon pollutant model at different gasoline concentrations (0, 5, 10 and 30 g/kg) in soil, each added with 10% (v/v) of S. marcescens. The dry and wet weights of the plants slightly increased on exposure to gasoline for 42 days. The highest wet weight in 10 g/kg gasoline was 100.5 g at 72 days while dry weight amount 35.6 g. In the 5 g/kg and 30 g/kg gasoline concentrations, the wet weights were 43.4 g and 10.8 g with 13.1 g and 6.3 g for dry weight respectively. The phytoremediation treatment using S. marcescens in 10 g/kg gasoline showed the highest total petroleum hydrocarbon (TPH) removal after 72 days of exposure of 89.5% compared to only 55.0% in the corresponding unplanted control. The maximum TPH removals in the other two phytoremediation treatments (5 and 30 g/kg gasoline) were 84.4 and 83.3%, respectively, while the average removal in the corresponding control treatments were 56.3 and 54.2% respectively. This indicates that the biodegradation process by S. marcescens played significant role in the treatment. Hence, the synergy interaction between S. mucronatus and the bacteria can be beneficial in remediation of hydrocarbon in gasoline contaminated soil.
