Bacillus pumilus strain CCMA-560 was isolated from an oil-contaminated mangrove swamp and was shown to produce biosurfactants. The strain appears to be capable of degrading some plant cell wall-related compounds, including hemicelluose and pectin. Genes for biopolymer export and polysaccharide intercellular adhesin synthesis were also annotated.

In 2013, China imported 282 million tons of crude oil with an external dependence of 58.1%, surpassing the USA as the world’s largest net oil importer. An import source diversification strategy has been adopted by China to ensure oil supply security and to prevent oil supply disruption. However, the strategy is restricted by the imbalance of oil reserves. What is the reasonable and clear object...

the economy's dependence on oil revenues and derivatives of these products make the country's economy heavily influenced by the volatility and instability of the pricing of these products. therefore, it seems necessary to develop non-oil exports. this paper examines the causality relation and the effect of foreign direct investment, economic openness and real exchange rate on non-oil ...

background: satureja sahandica is a perennial plant of the family lamiaceae and an aromatic plant of iran flora with its essential oil components used in culinary, medicinal, and perfume industries. objective: to identify components of s. sahandica planted in qazvin condition. methods: aerial parts of s. sahandica were collected from a research farm (qazvin agriculture and natural resources res...

Kazakhstan's export relies heavily on oil and other natural resources. Therefore, fluctuations in world prices have important consequences for economy. The effect of the real exchange rate is very economies trying to develop sectors as well gas such Kazakhstan. purpose this study examine possible asymmetric relationships between effective Kazakhstan period January 2010-December 2020. For purpos...

The objective of this paper is to investigate the impacts of implementation of the FTAA and China’s lower import tariffs on international trade of soybean oil, soybean meal, and soybeans. A two-commodity spatial model was formulated. The base model was calibrated to simulate the average level data of 1996, 1997, and 1998. Two alternative trade scenarios were simulated. The results indicated tha...

The aim of this study is to develop oil content measurement system using transmitted and scattered intensity. Two fluorescence analyses would be suggested with methods that it can use rapidly, continuously, conveniently and accurately in long-distance cruise vessels. The present paper consists of the structure of fluorescence measurement hardware and an interpretative analysis of experimental d...

abstract- over the past 50 years, oil mulching has been a common technique for sand dune stabilization in the southwest of iran (khuzestan province). however, concerns over the release of heavy metals from oil mulching have led to the search for alternative mulches that are capable of stabilizing sand dunes without environmental hazards. this study investigates the feasibility of using sugarcan...

In this paper, Steam Assisted Gravity Drainage (SAGD) is introduced and its advantages over ordinary steam injection is demonstrated. A simple simulation model is built and three scenarios of natural production, ordinary steam injection, and SAGD are compared in terms of their cumulative oil production and cumulative oil steam ratio. The results show that SAGD can significantly enhance oil prod...
