Objectives:
To improve the quality of diesel fuel via removal of aromatic compounds using Pseudomonas sp.
Results:
In the present study Pseudomonas sp. was able to remove 94% of fluorene, 59% of phenanthrene, 49% of anthracene, 52% of fluoranthene, 45% of pyrene and 75% carbazole present in diesel oil. Additionally, it also does not affect the aliphatic content of fuel thus maintaining the carbon backbone of the fuel.
Conclusions:
Pseudomonas sp. is a potential biocatalyst that can be used in the refining industry.
