In 1859, Edwin Drake drilled one of the world’s first commercial oil wells south of Titusville, PA, which produced 25 barrels of petroleum (then called rock oil) on its first day from a geological reservoir located 69 ft below the surface. At the time, people were beginning to recognize the value of petroleum, mostly for its ability to lubricate and illuminate. So, in a sense Drake’s gusher hel...

Water flooding plays an important role in recovering oil from depleted petroleum reservoirs. Exactly how the microbial communities of production wells are affected by microorganisms introduced with injected water has previously not been adequately studied. Using denaturing gradient gel electrophoresis (DGGE) approach and 16S rRNA gene clone library analysis, the comparison of microbial communit...

This review aims to address the current data on edible packaging systems used in food production. The growing global population, changes climate and dietary patterns, increasing need for environmental protection, have created an demand waste-free durable sustainable materials has become significant order avoid waste pollution. Edible emerged as a promising solution extend shelf life of products...

Petroleum based products are the major source of energy for industries and daily life. Leaks and accidental spills occur regularly during the exploration, production, refining, transport, and storage of petroleum and petroleum products. In the present study we isolated the bacteria from diesel contaminated soil and screened them for diesel biodegradation capacity. One monoculture isolate identi...

The biotransformation of phosphogypsum in cultures of sulfate-reducing bacteria (SRB) isolated from crude petroleum-refining wastewaters or purified using activated sludge method was studied. Selection was with the microcosms method on Postgate and minimal medium with different carbon sources, Emerson medium and petroleum-refining wastewaters. Highest hydrogen sulfide production, in excess of 5...

The understanding of the phylogenetic diversity, metabolic capabilities, ecological roles, and community dynamics taking place in oil reservoir microbial communities is far from complete. The interest in studying microbial diversity and metabolism in petroleum reservoirs lies mainly but not only on providing a better comprehension of biodegradation of crude oils, since it represents a worldwide...

1.1.1. Petroleum fuels It is estimated that between 1.7 and 8.8 million tons of petroleum hydrocarbons are released into the marine environment each year, with a best estimate of 3.2 million tons per year. Although major oil spills, like the Exxon-Valdez spill of 1989 or last summer’s Deepwater Horizon spill in the Gulf of Mexico, garner much media and citizen attention, you may be surprised to...

As part of a broad, multldlsciplinary effort to monitor the impact of petroleum exploration activities on the outer continental shelf areas of the Gulf of Mexico, the local effects of a drilllng rig on the benthic environment have been investigated. Petroleum hydrocarbons in or on seawater can become associated with suspended sediment partlcles I and be transported downward and incorporated int...

The transportation of petroleum represents one of the most strategically important circulations of resources in the global economy. Its role cannot be overstated. Yet, petroleum has become a “strategically invisible” commodity as its flow has been continuous with limited, but eye-opening, disruptions such as the First Energy Crisis is 1973. Petroleum supplies are virtually taken for granted. Si...

The microbial community response to petroleum seepage was investigated in a whole round sediment core (16 cm length) collected nearby natural hydrocarbon seepage structures in the Caspian Sea, using a newly developed Sediment-Oil-Flow-Through (SOFT) system. Distinct redox zones established and migrated vertically in the core during the 190 days-long simulated petroleum seepage. Methanogenic pet...
