  Chamomile is one of the most important drugs known to man and one of the most widely used as medicinal plants in Europe, the Middle East, North America, Australia and African.It is cultivated mainly in order to use its blue essential oils. Due to its increasing use in Pharmaceutical industry, cosmetics, perfumery and flavoring food preparation is very important.In this study, the seed oil of Matricaria urea L. were purchased from the company of Pakan Bazr Isfahan, ground and then were extracted by soxhlet apparatus. The obtained sample oil was concentrated by rotary device and then, the fatty acids of obtained oil were changed into ester by esterification method. Then the sample diluted and analyzed by GC / MS qualitatively and quantitatively. Of the 66 isolated compounds 22 compounds containing 91.7% of oil were identified. The main components were 8, 11-Octadecadienoic acid, methyl ester (53%) and n-Decane (15.8%). Manuscript profile

  Objective: Biosurfactants have wide applications in the microbiology of food and oil. The aim of this research was to investigate the production of stable biosurfactant in high temperature and salinity from yeasts isolated from oil-contaminated soil.Materials and methods: Bushnell Haas culture medium was used to screen biosurfactant producing yeasts. The presence of biosurfactant was evaluated using oil dispersion and surface tension reduction tests.Findings: The best biosurfactant producing strain of Radotrulla mucilaginosawas named GBMEIAUF1 and its 5.8s-rDNA gene sequence was registered inthe NCBI gene bank under accession number CBS11162. The results of thin layer chromatography and Fourier transform infrared spectroscopy confirmed that the extracted biosurfactant was sophorolipid with significant surface activity. Purified sophorolipid decreased the surface tension of water from 72 mN/m to 1.29 mN/m. The highest emulsification index, E24%, the extracted biosurfactant was 53% and retained 63.71 to 58.09% of its initial activity at 80 to 120 degrees Celsius. This biosurfactant also retained 82.67 and 89.41% of its initial activity at pH 10.5, and 12, 59.66% of its initial activity at 10% salinity.Conclusion: This research is the first report of sophorolipid production by the yeast Redotrula mucilaginosa.Due to its thermal stability and high pH and salinity tolerance, sophorolipid produced by Redotrula mucilaginosa can be strongly recommended as an effective emulsifying agent for application in microbial enhanced oil extraction programs as well as food industry.  Manuscript profile

  Today's the mostly of oil reservoirs specially Iranian south-west oil reservoirs due to production from these reservoirs are at their second half of life. Water or gas injection at secondary enhanced oil recovery (EOR) in order to stabilize or reduction of pressure depletion it will no longer be responsible for reducing production. Therefore, tertiary EOR methods are used to prevent the loss of production. One of the tertiary EOR methods is using chemical injections. Injection of chemicals into oil reservoirs is used to increase the viscosity of the injected fluid, to reduce the interfacial tension between the injected fluid and the fluid produced, as well as to change the wettability of the reservoir rock. One of these chemicals, which is mainly used in relatively high permeability reservoirs, is polymers that are used to increase the viscosity of the injected fluid and also increase the mobility ratio of the reservoir fluids. This leads to the relatively piston sweeping of the produced fluid in the reservoir and also the postponement of the moment to reach the breakthrough time. One of the main challenges in the injection of polymers into oil reservoirs is the absorption of these polymers on the reservoir rock, which in addition to reducing the polymer's effectiveness in the entire injection region, also increases the cost of injection. Therefore, in this study, the effect of nanoparticles in order to reduce the adsorption of polymers on the reservoir and therefore the less polymer needed to achieve a specific production in the reservoir and, consequently, to reduce the environmental damage in order to produce polymers and also to inject them into oil reservoirs have been dealt with. The results show a decrease in polymer adsorption by the nanoparticles studied. Manuscript profile

  In this paper, the proper modeling of the wettability modification mechanism in the process of water injection with low salinity was investigated using the eclyps simulator. Most reservoirs are in their late stages of production, and still a high percentage of oil is available in reservoirs; hence the need to find a way to increase oil production from these reservoirs is more and more felt. Hence, the methods of harvesting should be used. One of the ways of treating withdrawal can be low intake of water with salinity. In this project, the method of water injection with low salinity is investigated with the aim of increasing the recycling of oil. To achieve this goal, the Ellips simulator is used. The heavy oil fluid model is modeled for oil reservoir; then water injection is simulated with different salinity (low salinity). Salines are considered to be high salinity with a concentration of 45000 PPM and low salinity, with concentrations of 24000 PPM, 8000, respectively. Water injection with different salinity increases the recovery rate of oil. The results show that water injection with salinity of PPM is 8000, with an oil recovery rate of 38% to 50%.

  Abstract In the recent years use of plant essential oils (EOs) in the food and medicine industry is increasing. So, the aim of this study was to optimize effective factors for maximizing essential oil yield and evaluation of its composition under the optimal conditions. The effect of different parameters including different amounts of plant (X1), extraction time of essential oils (X2) and particle size of seeds obtained with mesh (X3) on three levels (1, 0, 1-) as independent variable to optimize essential oil percentage as dependent variables were evaluated using response surface methodology. The seeds of Heracleum persicum Desf. Ex Fischer were collected from Ayalono area (East Azerbaijan) in August 2015.  The essential oil was extracted by Clevenger apparatus and were identified by GC/MS. ANOVA analysis results and experimental error for the RSM model were showed that the predicted model for the essential oil percentage was significantly accurate (P Manuscript profile
