Microbial Transformation of Carbazole to Anthranilic Acid by Pseudomonas stutzeri.
This study examined the microbial transformation of carbazole (CZ) by an isolated bacterium that can use CZ as a sole carbon and nitrogen source. The strain identified as Pseudomonas stutzeri produced a large amount of anthranilic acid (AA) from CZ in the medium containing a nonionic surfactant. In dialysis culture using ion-exchange resin, 7.9 g/liter (58mm) of AA was accumulated from 15g/lite...
متن کاملSiderophore production by Pseudomonas stutzeri under aerobic and anaerobic conditions.
The siderophore production of the facultative anaerobe Pseudomonas stutzeri, strain CCUG 36651, grown under both aerobic and anaerobic conditions, was investigated by liquid chromatography and mass spectrometry. The bacterial strain has been isolated at a 626-m depth at the Aspö Hard Rock Laboratory, where experiments concerning the geological disposal of nuclear waste are performed. In bacteri...
متن کاملIndole production by Pseudomonas stutzeri strain NAP-3 during anaerobic naphthalene biodegradation in the presence of dimethyl formamide.
We previously reported on the denitrifier Pseudomonas stutzeri strain NAP-3 that degrades naphthalene without oxygen. In our present studies, naphthalene biodegradation by NAP-3 was slow or nearly absent when acetate was not present, suggesting a stimulating effect by the non-fermentable substrate. NAP-3 was sensitive to the amount of naphthalene in the culture; with naphthalene removal and nit...
متن کاملEfficient biodegradation of high-molecular-weight polyethylene glycols by pure cultures of Pseudomonas stutzeri.
Biodegradation of polyethylene glycols (PEGs) of up to 13,000 to 14,000 molecular weight has been shown to be performed by a river water bacterial isolate (strain JA1001) identified as Pseudomonas stutzeri. A pure culture of strain JA1001 grew on PEG 1000 or PEG 10000 at 0.2% (wt/vol) as a sole source of carbon and energy with a doubling time of 135 or 150 min, respectively. Cultures metabolize...
متن کاملBiodegradation kinetics of benzoic and anthranilic acids by Micrococcus sp
This study presents biodegradation of benzoic acid (BA) and anthranilic acid (AA) by Micrococcus sp. under aerobic conditions. Initial concentrations of BA and AA were varied (500-2500 mg/l) and almost complete biodegradation of BA and AA was observed within 30 h. Andrews kinetic model for single substrate was fitted to obtain maximum specific growth rates, half saturation and substrate inhibit...
