There are many microbes that exist in the environment and some of these microbes have the ability to degrade hydrocarbons. The ability of biodegradation of diesel by strain ReTOS-W1, ReTOS-Cr1, and consortia (ReCO-Cr2, RdPOS-Cr1. ReTOS-Cr2, ReTOS-Cr3, ReTOS-Cr4, and RePOS-W1) are being carried out using landfarming technology. Results of the study show that consortia are able to degrade 54.31 % of diesel. While ReTOS-W1 are able to degrade 44.87 % of diesel and ReTOS-Cr1 are able to degrade 47.03 % of diesel. Based on the results, it is known that consortia are more effective in diesel biodegradation than other single strain. Parameters that influenced diesel biodegradation were also determined during the study. The results show that during the experiment, temperature is in the ideal range for microbial activities which is between the ranged 24°C to 34 °c. However, pH of these plots during experiment is slightly acidic which is 4 to 5.6. Moisture content on the other hand, is not in the ideal range or microbial activities, which is around 5 % to 20 %. This study shows that moisture content have more influence to the biodegradation of diesel as compared to pH and temperature.
