background: long-term extraction and production of various oil derivatives causes contamination of soil adjacent to production and refining area. the main important issue is the ecological hazard of these pollutants. the main aim of the study was to identify and separate native bacteria that are responsible for degradation of oil contaminated fields. methods: we prepared a compound sample of co...
Mangrove forests are coastal ecosystems that found worldwide in tropical and subtropical zones. Oil spill causes damage to these marine ecosystems. The objective of this study is study the oil-degrading bacteria in some mangrove forests that located at Persian Gulf. In this study sediments and plant materials were collected from mangrove forests at Persian Gulf (Minab and Khamir ports). Oil-deg...
Soil enzymes are the catalysts for important metabolic process functions including the decomposition of organic inputs and the detoxification of xenobiotics. The aim of this research was to determine the pattern of variation in the activities of dehydrogenase, urease, lipase and phosphatase enzymes, determining the number of hetrotrophic and degrading bacteria and measuring the soil respiratio...
Over the past few years, a new and ecophysiologically unusual group of marine hydrocarbon-degrading bacteria - the obligate hydrocarbonoclastic bacteria (OHCB) - has been recognized and shown to play a significant role in the biological removal of petroleum hydrocarbons from polluted marine waters. The introduction of oil or oil constituents into seawater leads to successive blooms of a relativ...
background: the contamination of ecosystem with petroleum and its derivatives is considered as one of the most crucial environmental threat in iran. application of microorganisms has been demonstrated as an appropriate and more practical alternative to clean-up petroleum hydrocarbons in the contaminated environments. objectives: the objectives of this study were isolating rhizosphere-inhabiti...
Petroleum hydrocarbons are important energy resources used by industry and in our daily life, whose production contributes highly to environmental pollution. To control such risk, bioremediation constitutes an environmentally friendly alternative technology that has been established and applied. It constitutes the primary mechanism for the elimination of hydrocarbons from contaminated sites by ...

Some properties of compounds in degrading bacteria are required for biodegradation of contaminants to higher performance. Those strains which have a high percentage of these features are more effective at biodegradation. The present experiments were designed to measure these parameters. In this study, measurement of cell surface hydrophobic-degrading bacteria was designed which oil was separate...
in this study, among the 21 diesel-degrading bacteria that were isolated from an oil-polluted area in fars (iran), 6 bacterial strains were tested for their capability to metabolize and grow on diesel oil by degrading its hydrocarbons content. the biochemical characteristics and 16s rrna sequence analysis of diesel-degrading bacteria showed that these strains were related to the genus pseudomon...
