Abstract
One of the most commonly cited environmental pollutant is the mono aromatic group of hydrocarbons BTEX. The biodegradation potential of three pure cultures, Pseudomonas putida F1, Rhodococcus zopfii, and Pseudomonas stutzeri was studied individually as well as in combinations. The overall objective was to combine the three species into a bacterial concoction that can effectively biodegrade BTEX. In the pure substrate systems, Pseudomonas putida F1 and Rhodococcus zopfii degraded toluene, benzene, and ethyl benzene, whereas Pseudomonas stutzeri degraded toluene, benzene, and o-xylene as sole sources of carbon. In the mixed substrate systems, a biodegradation hierarchy existed, with toluene being the most easily degraded compound followed by benzene, ethyl benzene, and o-xylene for all the three species. This is an abstract of a paper presented at the AIChE Annual Meeting (Salt Lake City, UT 11/4-9/2007).
