Although oil pollution is difficult to treat, petroleum hydrocarbon-degrading bacteria have evolved as a result of existing in close proximity to naturally occurring petroleum hydrocarbons in the environment.

Such organisms are candidates for the treatment of oil pollutants (Margesin et al., ; Ron and Rosenberg, ; Lea-Smith et al., Cited by:   Microbial Degradation of Oil It is gmerally assumed that bacteria in the sea ca, degrade almost anyflmbg they are ofered, and it is widely ~ed that peColmm on t~ e~irdy biodegai- able.

Bacteria and filamentous fungi participate in the PH biodegradation (Rahman et al., ). In the past few years the biodegradation of ligninolytic fungi has been by:   Resistance of hydrocarbon pollutants to microbial degradation in either soil or water tends to increase with the type as well as molecular weight and number of rings (incase of PAHs).

Naphthalene is readily biodegraded in most situations however PAHs with four, five, or six rings tends to be degraded much more by:   The microbial organisms transform the substance through metabolic or enzymatic processes. It is based on two processes: growth and cometabolism. In growth, an organic pollutant is used as sole source of carbon and energy.

This process results in a complete degradation (mineralization) of organic pollutants. Although oil pollution is difficult to treat, petroleum hydrocarbon-degrading bacteria have evolved as a result of existing in close proximity to naturally occurring petroleum hydrocarbons in the environment.

Such organisms are candidates for the treatment of oil pollutants (Margesin et al., ; Ron and Rosenberg, ; Lea-Smith et al.,   The knowledge of the efficiency and the activities of bacteria in oil-polluted sites may be helpful for the bioremediation of oil spills, since human action, by using specific microbial consortia, can be planned in order to clean up oil pollution (Denaro et al., ).

BAC process is developed to use the Microbial degradation of oil pollutants book effect of adsorption of pollutants on the adsorbent and subsequently degradation by microbial activity in wastewater treatment process.

Due to high surface area and pore size the activated carbon is characterized by its great effect on absorbing organic pollutants in wastewater, and further.

The major organic pollutants of point sources are mineral oil, fuel components, and chlorinated hydrocarbons.

Research from the last two decades discovered that most of these compounds are biodegradable under anoxic conditions. Studying the mechanism of microbial degradation of petroleum hydrocarbon pollutants is conducive to exploring the path of petroleum pollution remediation technology and improving the efficiency of.

Complete genomes were also determined for bacteria capable of anaerobic degradation of halogenated hydrocarbons by halorespiration: the ~ Mb genomes of Dehalococcoides ethenogenes strain and Dehalococcoides sp. strain CBDB1 and the ~ Mb genome of Desulfitobacterium hafniense strain Y Characteristic for all these bacteria is the.

Microbial Biodegradation and Bioremediation brings together experts in relevant fields to describe the successful application of microbes and their derivatives for bioremediation of potentially toxic and relatively novel compounds. This single-source reference encompasses all categories of pollutants and their applications in a convenient, comprehensive package.

The process uses microscopic organisms (primarily bacteria) that live on soil and ‘eat’ petroleum hydrocarbon. A number of influencing degradation factors has been identified to reduce the toxicity of oil contamination in the environment by removing, degrading or transforming contaminants.

a) degradation of pollutants by microbes directly b) removal of pollutants and collection at a place to facilitate microbial degradation c) degradation of pollutants by genetically engineered microbes d) none of these 7.

Which of the following microbe is widely used in the removal of industrial wastes a) Trichoderma sp b) Aspergillus niger. Potential application of crude oil degrading bacteria in oil spill and waste management.

For example Hassanshahian et al () show that oil contamination can induce major changes in marine microbial communities at Persian Gulf and Caspian Sea, that when the pollution occur the number of crude oil degrading bacteria increased and also inhibit some catalytic enzymes.

Microbial community in the intertidal sediments plays an important role in the degradation of heavy oil pollutants.

Description Microbial degradation of oil pollutants FB2

The composition of heavy oil pollutants and their degradation products also affect the microbial community in the intertidal zones (Paissé et.

The book also explains the latest technologies used for the degradation of pollutants in several niche ecosystems. Given its scope, the book will be of interest to teachers, researchers, bioremediation scientists, capacity builders and policymakers.

In this book international experts discuss the state-of-the-art in the biological degradation of hydrocarbons to meet remedial or disposal goals. The work focuses on practical applications, often on globally important scales including the remediation of some of the world’s largest crude oil spills.

A number of bacteria viz. Bacillus subtilis, B. megaterium, E. coli, Chromobacter sp are quite efficient in phenol degradation. Thus disposal of refinery and oil field wastes into the river or sea needs proper microbial treatment for control of oil pollution into the sea.

Bacteria represent the major class of microorganisms involved in the degradation of hydrocarbons [2, 13]. There are two approaches for bioremediation: bioaugmentation and biostimulation [14–16]. Bioaugmentation consists in the addition of highly efficient oil-degrading bacteria to improve and enhance the degradation.

Based on a representative and accurate example, this paper describes both fundamental and applied benefits in investigating microbial degradation of organic pollutants. Read more Article. The microbial degradation of oil pollutants: workshop held at Georgia State University, December, degraders normally constitute less than 1% of the total microbial community.

When oil pollutants are present these hydrocarbon-degrading populations increase, typically to 10% of the community (Alexander, ). Rates of natural degradation typically have been found to be low and are limited by environmental factors, such as, the contaminant.

In the bioremediation process, the concentration of pollutants affects microbial degradation, and too high or too low concentration leads to the decrease in the efficiency of microbial degradation.

As seen in Fig 3, the crude oil concentration greatly influenced the degradation of crude oil by the free and the immobilized bacterial consortium.

Genetic potential of oil-eating bacteria from the BP oil spill decoded Bacteria in the world's oceans produce millions of tonnes of hydrocarbons each year.

This would often lead to oxygen depletion in environments heavily polluted with oil. Studies in recent years have proven that there are numerous anaerobic bacterial species capable of decomposing this group of pollutants.

A common feature among these bacteria is that they possess reductive dehalogenases. petroleum hydrocarbon degrading bacteria was as follows. mL of crude oil medium (SM) and g/mL yeast extract powder were placed in a clean conical flask, and 2 mL of the col-lected oil polluted seawater samples was injected by sterile syringe to the crude oil.

Hence, the microbial consortium involved in detergent degradation process had more of bacterial species than fungal. Alkalinophilic microbial consortium succeeded the acidophilic population that started the biodegradation process in an autogenic succession fashion.
