“…24 This microorganism is an actinomycete that forms hyphae, which by breaking the down produces rod-shaped or coccus cells. Several studies have reported the use of this specie in the degradation of aliphatic compounds, 25 crude oil, 15,26 diesel, 13 biodiesel, 14 some PAHs 16,27 and di-n-octyl phthalate. 17 However, there is a paucity of studies on enzyme degradation use by Gordonia for bioremediation.…”

Recebido em 23/1/12; aceito em 23/4/12; publicado na web em 20/7/2012 This study aimed to evaluate the environmental conditions for enzyme activity of catechol 1,2-dioxygenase (C1,2O) and catechol 2,3-dioxygenase (C2,3O) produced by Gordonia polyisoprenivorans in cell-free and immobilized extracts. The optimum conditions of pH, temperature, time course and effect of ions for enzyme activity were determined. Peak activity of C1,2O occurred at pH 8.0. The isolate exhibited the highest activity of C2,3O at pH 7.0 and 8.0 for the cell-free extract and immobilized extract, respectively. This isolate exhibited important characteristics such as broad range of pH, temperature and time course for enzyme activity.

“…30 On the other hand, the non-assimilation of complex molecules by the microorganisms may determine the end point of several metabolic processes in hydrocarbon-contaminated soils. 31 In order to avoid negative impacts caused by the presence of toxic compounds, the microbial population uses a metabolic arsenal to guarantee its integrity and stability, through a mechanism known as tolerance. Tolerance acts as a mechanism of compensation against the caustic effects of the environment, where the microbial communities are established, increasing the chances of the removal of compounds with difficult degradation.…”

Recebido em 5/2/10; aceito em 23/8/10; publicado na web em 30/11/10Alternatives for the removal of high-molecular weight polycyclic aromatic hydrocarbons (HWM-PAH) from soil were tested by adding fertilizer or glycerol, as well as the combination of both. Experiments were carried out for 60 days in reactors containing a HWM-PAH-contaminated soil (8030 μg kg -1 ), accompanied by pH monitoring, humidity control and quantification of total heterotrophic bacteria and total fungus. Fertilizer addition removed 41.6% of HWM-PAH. Fertilizer and glycerol in combination removed 46.2%. When glycerol was added individually, degradation reached 50.4%. Glycerol also promoted the increase of degradation rate during the first 30 days suggesting the HMW-PAH removal occurred through cometabolic pathways.
