Petroleum hydrocarbon-degrading fungi were isolated from Detarium senegalense seeds. An assessment of the relative ability of each fungus to degrade petroleum crude oil, diesel, unspent and spent engine oils, kerosene and Detarium senegalense oil extract, on minimal salt broth, was done measuring change in optical density read on a spectrophotometer. Five fungi were isolated from diseased namel...
Based on the information from an actual petroleum-contaminated site, a one-dimensional soil column was used to examine vertical transportation diversities of different petroleum components under influence water table fluctuations, and results revealed following: (1) There were two obvious pollution accumulation zones condition fluctuations: (i) The infiltration zone dominated by residual phase ...
OBJECTIVES The present study investigated the toxic properties of petroleum ether extract of Wattakaka (W.) volubilis in Wistar female rats. METHODS An in vitro brine shrimp lethality bioassay was studied in A. Salina nauplii, and the lethality concentrations were assessed for petroleum ether extract of W. volubilis. A water soluble portion of the test extract was used in different concentrat...
Petroleum substances are the main source of pollutants stored in old waste pits. They cause degradation of biological life in the area of storage. The aim of this article is to present laboratory research on petroleum pollutant biodegradation. The hydrocarbon contaminants in old drilling wastes came from the Graby-19 waste pit. The tests included basic bioremediation and inoculation with a biop...
The present study was aimed at evaluation of the anti-inflammatory, analgesic and antipyretic activities of petroleum ether and ethanolic extract of aerial parts of Mollugo pentaphylla Linn. In experimental standard models. The results showed that the ethanolic extract significantly reduce the edema induced by carrageenan within 1 to 3 hrs. post dosing and Cotton-pellet induced granuloma models...
The efficiency of Bacillus subtilis DM-04 and Pseudomonas aeruginosa M and NM strains isolated from a petroleum contaminated soil sample from North-East India was compared for the biodegradation of crude petroleum-oil hydrocarbons in soil and shake flask study. These bacterial strains could utilize crude petroleum-oil hydrocarbons as sole source of carbon and energy. Bioaugmentation of TPH cont...
Near-infrared (NIR) spectroscopy has been successfully utilized for the rapid identification of six typical petroleum products such as light straight-run (LSR), naphtha, kerosine, light gas oil (LGO), gasoline, and diesel. The spectral features of each product were reasonably differentiated in the NIR region, and the spectral differences provided enough qualitative spectral information for disc...
There is a relationship between the economic requirements for development of oil and gas facilities in oil-producing regions North environmental problems sustainable development. One ways to solve this problem wider use underground storage both reducing peak loads Unified Gas Supply System by collecting storing previously flared associated petroleum gas, burying large volume industrial emission...
Efforts are being made throughout the World to reduce the consumption of liquid petroleum fuels wherever is possible. Biodiesel is recently gaining prominence as a substitute for petroleum based diesel mainly due to environmental considerations and depletion of vital resources like petroleum and coal. According to Indian scenario, the demand for petroleum diesel is increasing day by day hence t...
Road vehicles are a key part of the climate change challenge, representing both an important source of petroleum demand and greenhouse gas (GHG) emissions worldwide. In the United States, light-duty vehicles (LDVs, i.e., cars and light trucks) alone account for 43% of petroleum demand and 23% of GHG emissions, when fuel production is considered [MacKenzie, 2013]. The United States, Europe, Chin...
