• A unique strain of bacterium isolated from soil contaminated with petroleum products, can selectively remove from the environment toxic, aromatic pollutants such as benzoate, benzyl alcohol and naphthalene, to name a few. What makes the bacterial strain (Pseudomonas putida CSV86) unique is its preference for
• aromatic compounds and organic acid as a food source even when glucose is available. The strain can degrade aromatics and organic acids simultaneously.

Uses of bacterial strain:

• The bacterial strain is a very good candidate for bioremediation or waste-water treatment. We can increase the metabolic diversity and capacity by genetically engineering the strain.
