Oil contaminated soil, sea water and sediment samples were collected from old oil jetty of Paradip port, Orissa. These samples were screened for bacterial oil degradation using 0.5% diesel in Bushnell-Hass Mineral Salt medium. Samples were incubated separately in shaking orbital incubator at 37 0 C at 125rpm up to 15days. The level of petroleum hydrocarbon degradation was determined by gravimet...

We designed and studied hydrocarbon model compounds by high-resolution noncontact atomic force microscopy. In addition to planar polycyclic aromatic moieties, these novel model compounds feature linear alkyl and cycloaliphatic motifs that exist in most hydrocarbon resources - particularly in petroleum asphaltenes and other petroleum fractions - or in lipids in biological samples. We demonstrate...

Recent advances in interdisciplinary fields as diverse as astrophysics, cosmogeophysics, nuclear geology, etc. have led to interesting developments in the non-organic theory of the genesis of petroleum. This theory, which holds that petroleum is of an abiogenic primordial origin, provides an explanation for certain features of petroleum geology that are hard to explain within the standard organ...

the mandovi estuary is highly influenced by mining and tourism related activities in the centralwest coast of india. vertical fluxes and accumulation of petroleum hydrocarbons (phcs) in three sedimentcores (d1, c1 and og) from the mandovi estuary were assessed using ultra-violet fluorescence (uvf)spectroscopy. the range of phcs values in estuarine sediments varied from 5.4 to 12.34 μg/g enrichm...

Petroleum hydrocarbon profiles of water and sediment samples of Algoa Bay in the Eastern Cape Province of South Africa were assessed using standard analytical procedures. Water (from surface and bottom levels) and sediment samples were collected from five locations in the bay from February to June 2016. Extraction of the petroleum hydrocarbons from the water and sediment samples collected was a...

Problem statement: Petroleum hydrocarbon and petroleum residue (i.e., spent oil) remains the foremost pollutants to the fish communities in various aquatic media-ponds, streams, rivers, creeks, coastal and marine environments through indiscriminate disposal of oil contaminated drilling muds, cutting and oil spillages. Approach: Also, the spent oil enters into aquatic media through run-off follo...

The relationship between toxicity and soil contamination must be understood to develop reliable indicators of environmental restoration for bioremediation. Two bacterial rapid bioassays, SOS chromotest and the umu test with and without metabolic activation (S-9 mixture), were used to evaluate the genotoxicity of petroleum hydrocarbon-contaminated soil following bioremediation treatment. The soi...

We assessed the feasibility of involvement of Accredited Social Health Activist (ASHA) in newborn care. All the ASHAs (n = 33) of PHC Dayalpur, Faridabad district of Haryana were trained for one day which was followed by two refresher trainings. The mean (SD) knowledge score (out of 11) of ASHAs were 6.45 (2.44), 6.50 (2.01), 7.45 (1.36) and 7.15 (1.27) at pre-training, immediately after traini...

Petroleum hydrocarbon contamination is a major global prevalent issue in the petroleum sector. This research focuses on evaluating biodegradation of three Gram-negative bacilli, isolated from cowpea planted soil, contaminated with kerosene. The Gram negative bacilli strains have been characterized and identified, using MicrobactTM ID24E systems for the identification of Enterobacteriaceae and c...
