Physiological characterization of carbazole degrading bacteria isolated from a former gasworks site

Heterocyclic compounds could remain in the environment as hazardous and resistant pollutants. The aim of this study was to determine the physiological features of Methylobacterium sp. GPE1 strain being able to degrade heterocyclic compounds. Ten various substrates (sugars, alcohols and acids) were used in this assay, for metabolic purposes and eight ones were used as a sole source of carbon and energy. The comparison of the results with data taken from the literature indicated that GPE1 could be a new species of Methylobacterium sp.
