The use of laser induced fluorescence (LIF) spectroscopy to characterize crude oil has privileges compared to conventional techniques in terms of reducing the size of sample, rapidity of measurements, high sensitivity and simplicity of sample handling and possibility of in situ measurements. The fluorescence radiation emitted from crude oil is the result of the interaction between the aromatic ...

Delivery of micrometeorite kerogen to the Hadean oceanic crust. Kerogens are abundant byproducts of incomplete combustion, pyrolysis and radiation reprocessing of almost any kinds of organic precursors. Therefore they are observed in a wide variety of environments, including: ▬ terrestrial shales, ▬ the fine-grained matrix of hydrous-carbonaceous chondrites (HCCs) such as Murchison; ▬ the inter...

Among four crude oil-degrading fungi strains that were isolated from a petroleum-polluted area in the Rumaila oil field, two fungi strains showed high activity in aliphatic hydrocarbon degradation. ITS sequencing and analysis of morphological and biochemical characteristics identified these strains as Penicillium sp. RMA1 and RMA2. Gravimetric and gas chromatography analysis of the crude oil re...

The methanol, ethanol and petroleum ether soluble crude and fractions extract of Gliricidia sepium and Spathodea campanulata leaf were examined for antibacterial activities, phytochemicals and possible sources of antioxidant. The antibacterial activity of the crude and fractions were carried out against nine clinical bacteria isolates using the agar well and disc diffusion methods respectively....

Biochemical changes in the serum and liver of albino rats chronically exposed to rats administered 5gk , 7.5gk and 15gk of gasoline , kerosine and crude petroleum(bonny light) respectively were studied. The petroleum samples were administered intraperitoneally and the biochemical changes in the rat serum and the liver wree monitored over a three monthduration:Asparate amino transferase (AST) Al...

Antibacterial activity of two cyanobacterial strains i.e. Nostoc polludosum and Cylindrospermum licheniforme was studied. Both cyanobacterial strains were isolated from agricultural fields of Varanasi, India. Crude extracts of both strains in five solvents i.e. Ethanol, Petroleum ether, Acetone, Methanol, and Chloroform were screened against two human pathogenic bacteria i.e. S. aureus and E. c...

The widespread problem caused due to petroleum products, is their discharge and accidental spillage in marine environment proving to be hazardous to the surroundings as well as life forms. Thus remediation of these hydrocarbons by natural decontamination process is of utmost importance. Bioremediation is a non-invasive and cost effective technique for the clean-up of these petroleum hydrocarbon...

Remediation of the petroleum contaminated soil is essential to maintain the sustainable development of soil ecosystem. Bioremediation using microorganisms and plants is a promising method for the degradation of crude oil contaminants. The effects of different remediation treatments, including nitrogen addition, Suaeda salsa planting, and arbuscular mycorrhiza (AM) fungi inoculation individually...

A significant quantum of crude oil is trapped in reservoirs and often unrecoverable by conventional oil recovery methods. Further downstream, the petroleum industry is facing challenges to remove sulfur, metal, nitrogen as well as undesirable organic compounds from the crude. Conventional secondary recovery methods such as water and gas injections helped to increase the productivity of the well...
