HREE DIFFERENT newly isolated marine fungi were subjected ........to 18S rRNA gene partial sequence analysis. The resulting sequences showed that the isolates belong to Fusarium solani, Trichoderma viride and Aspergillus niger. The isolates have the ability to utilize some petroleum hydrocarbons such as hexane, motor oil and diesel oil. The tested fungi could grow up to 7 days, especially on me...

formation of non bonded organic layer around inorganic particles like iron sulfide and zeolites, was hypothesized as starting point for one of the possible mechanisms of the origin of life on earth. in this study, the general circumstances needed for creation of such organic layer was investigated. an aliphatic hydrocarbon (hexane), an aromatic hydrocarbon (toluene), an alcohol (n-octanol) and ...

The middle phase microemulsions of alkyl polyglucosides (APG) C8G1.46, C10G1.46, C12G1.46, C8/10G1.31 and C12/14G1.43 have been studied with the alcohol concentration scanning phase diagram. The results show that in the quaternary system of APG/alcohol/alkane/water, the increase in the alcohol concentration causes a series of phase inversion Winsor I (2) → III(3) →II( 2 ). The order of the alco...

The requirements of micronutrients for biomass and hydrocarbon production in Botryococcus braunii UTEX 572 were studied using response surface methodology. The concentrations of four micronutrients (iron, manganese, molybdenum, and nickel) were manipulated to achieve the best performance of B. braunii in laboratory conditions. The responses of algal biomass and hydrocarbon to the concentration ...

Fluorous protic ionic liquids (FPILS) containing a perfluorinated anion and hydrocarbon cation have been observed to segregate into nano-scale fluorocarbon, hydrocarbon and polar domains. The solubility and interactions of ethanol and butanol in a series of FPILs has been investigated by synchrotron source small and wide angle X-ray scattering. Nano-scale objects were found to be present within...
