Deep geothermally heated oil stratifications represent newly recognized non-volcanic islands of microbial life at extremely high temperatures, some 3,500 m below the surface. Samples of produced fluids contain high concentrations of various anaerobic extremely thermophilic and hyperthermophilic archaea and bacteria, indicating the presence of complex microbial communities in situ. The isolates ...

In several oilfields, reservoir souring by generation of hydrogen sulfide (H2S) occurs in secondary recovery during which seawater is injected into originally sweet reservoirs. At the production site, high concentrations of H2S can cause severe damage to both equipment and human personnel. Proper modeling of H2S concentration in produced fluids can be useful for decision-making duringfield deve...

In order to determine the factors of decay and sourness fig fruits, in summer 2016-17, 60 leaf, fruit stem samples from different regions Tehran, Varamin (Qal'e No), Mazandaran (Amol, Noor Sari), Lorestan Iran a branch sample Italy were collected. We obtained 30 isolates sample. The pathogenicity confirmed by artificially inoculation using fruits. They also characterized based on key ph...

Gaseous impurities, such as O2, are expected to be present within CO2 captured for storage. This could stimulate microbial activity in a geological storage site which has the potential lead operational issues injection well blockages, corrosion and oil souring. A series of experiments were carried out examine effect 10 ppm 100 O2 an anoxic (CO2 or N2) atmosphere on communities gas production la...

Abstract The urgent need to accelerate on, and make a national success of, the green digital transition is leading widespread calls for greater government involvement in economy, including by means of an active industrial policy. After reviewing several case studies, it becomes evident that, against conventional wisdom, nearly all countries have systematically engaged some form policy, especial...

Microbial processes sour oil, corrode equipment, and degrade hydrocarbons at an annual global cost to the oil gas industry of nearly $2 billion. However, top-down control these microbial can reduce their damage enhance recovery. Here, we screened communities from five wells in Illinois basin evaluated nutrient injection strategies metabolism community composition. Molasses with molybdate supple...

Myocardial infarction caused by coronary artery obstruction results in the loss of heart muscle, which is subsequently replaced scar tissue with limited therapeutic options. Cardiac patch based therapy has emerged as a promising strategy for treatment severe myocardial infarction. They are designed to be attached surface heart, that is, they meant “patch” injured thus restoring damaged or faili...
