The bioavailability of organic contaminants to the degrading bacteria is a major limitation to efficient bioremediation of sites contaminated with hydrophobic pollutants. Such limitation of bioavailability can be overcome by steady-state biofilm-based reactor. The aim of this study was to examine the effect of such multicellular aggregation by naturally existing oil-degrading bacteria on crude ...

The contamination of crude oil in soil matrices is a persistent problem with negative repercussions because the recalcitrant, hazardous, and mutagenic properties its constituents. To mitigate effect soil, use microorganisms cheap feasible option. In current study, bacterial species from numerous polluted field surfaces were isolated examined for their ability to degrade oil. Random samples hydr...

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 ...

In this study, the identity and distribution of plants and the structure of their associated rhizobacterial communities were examined in an oil-contaminated site. The number of plant species that formed a community or were scattered was 24. The species living in soil highly contaminated with total petroleum hydrocarbon (TPH) (9,000-4,5000 mg/g-soil) were Cynodon dactylon, Persicaria lapathifoli...

Phytoremediation is a promising technique for cleaning petroleum contaminated soils. In this study, the effects of two grass species (Festuca arundinacea Schreb. and Festuca pratensis Huds.), infected (E(+)) and non-infected (E(-)) by endophytic fungi (Neotyphodium coenophialum and Neotyphodium uncinatum, respectively) on the degradation of petroleum hydrocarbons in an aged petroleum contaminat...

The crude oil degradability and plasmid profile of autotrophic nitrifying bacteria, Nitrosomonas and Nitrobacter species, isolated from mangrove sediment in the Niger Delta of Nigeria were studied. The effects of temperature, pH and optical density on the utilization of different carbon sources by the bacteria were also investigated. Results showed that nitrifying bacteria could utilize kerosen...
