This study presents the bioremediation effect on the performance of hill bamboo Drepanostachyum falcatum on different soil combinations affected by crude oil pollution. Bioremediation was applied into the soil combination substrates by adding biodegrading bacteria using Pseudomonas fluorescen and Bacillus subtilis. Six treatments made with combinations of soil, bacteria, fertilizer and crude oil were used for this study. Increase in the plant height was observed as a result of treatment combination of soil, crude oil, bacteria and fertilizer. It also increased the proportion of plant emergence. The results were not so significant with other crude oil pollution treatments. These results open the door for more research to investigate the scalability of this bioremediation and also the possibility to have the same bioremediation effect against other type of pollution.
Key words: Soil microorganisms, bioremediation, pollution, plant growth, hill bamboo.
