Bacterial promoters triggering biodegradation of aromatic pollutants.
Unraveling the complex transcriptional regulation of bacterial catabolism of aromatic pollutants is a prerequisite for engineering efficient biological systems for many biotechnological applications. A first level of regulation relies on specific regulator-promoter pairs. There have been new insights into the molecular mechanisms that regulatory proteins use to sense a given signal and to activ...
متن کاملBacterial degradation of aromatic pollutants: a paradigm of metabolic versatility.
Although most organisms have detoxification abilities (i.e mineralization, transformation and/or immobilization of pollutants), microorganisms, particularly bacteria, play a crucial role in biogeochemical cycles and in sustainable development of the biosphere. Next to glucosyl residues, the benzene ring is the most widely distributed unit of chemical structure in nature, and many of the aromati...
متن کاملDoes toxicity of aromatic pollutants increase under remote atmospheric conditions?
Aromatic compounds contribute significantly to the budget of atmospheric pollutants and represent considerable hazard to living organisms. However, they are only rarely included into atmospheric models which deviate substantially from field measurements. A powerful experimental-simulation tool for the assessment of the impact of low- and semi-volatile aromatic pollutants on the environment due ...
متن کاملPolycyclic Aromatic Hydrocarbons as Environmental Pollutants: A review
Polycyclic aromatic hydrocarbons (PAHs) represent a group of persisting and prevalent environmental pollutants that are harmful to the environment and humans due to their toxic, mutagenic and carcinogenic potential. The emission of PAHs into the environment has increased with the increase in demand for petroleum products. The incomplete combustion of organic products such as coal, fuel oil, fir...
متن کاملCoral: QSPR modeling of rate constants of reactions between organic aromatic pollutants and hydroxyl radical
The rate constants (K(OH)) of reactions between 78 organic aromatic pollutants and hydroxyl radical were examined. Simplified molecular input line entry system was used as representation of the molecular structure of the pollutants. Quantitative structure-property relationships was developed using CORAL software (http://www.insilico.eu/CORAL) for four random splits of the data into the subtrain...
