Evaluation of both tenso-active and emulsifying activities indicated that a biosurfactant was produced by the newly isolated and promising strain Candida glabrata isolated from mangrove sediments. The extracellular water-soluble emulsifying agent was isolated and identified as a heteropolymer. The maximum of bioemulsifier production was observed when the strain was grown on soluble and insolubl...

mechanisms of tolerance to water deficiency stress for introducing sunflower hybrid was investigated by a two-factor experiment as a split plot design based on rcbd was at the research station in alborz province, hashtgerd region, iran in 2013. irrigation rates (irrigation after 50, 100 and 150 mm cumulative evaporation from class a evaporation pan) were considered in the main plots and sunflow...

The phenolic antioxidants 2,6-ditertiary-butyl paracresol (DBPC) (also known as butylated hydroxytoluene (BHT)) and 2,6-ditertiary-butyl phenol (DBP) are the two most common oxidation inhibitors added to the electrical insulating (transformer) oil and mineral oil based lubricants. The typical recommended value of DBPC and DBP in fresh electrical insulating oil is approximately 0.3% by weight. T...

The soybean (Glycine max l. merr) is one of oil seed plants from leguminous family. In this study, the effect of gamma radiation on chlorophyll, soluble and insoluble carbohydrate and composition oil seeds were investigated in soybean. Soybean variety J.K was irradiated with 0,100,200 and 300 gamma ray. The treatment and control seeds planed in with four replicates. The highest amount of total ...

BACKGROUND AND AIMS Previous studies have reported effects of pollen source on the oil concentration of maize (Zea mays) kernels through modifications to both the embryo/kernel ratio and embryo oil concentration. The present study expands upon previous analyses by addressing pollen source effects on the growth of kernel structures (i.e. pericarp, endosperm and embryo), allocation of embryo chem...

A new emulsion gelation method was used to prepare gel beads for a highly water-soluble drug metformin hydrochloride using sodium alginate as the polymer. The gel beads containing oil was prepared by gently mixing or homogenizing oil and water phase containing sodium alginate which was then extruded into calcium chloride solution to produce gel beads. The effects of factors like type of oil and...

Oil spills are the significant sources of hydrocarbons entering in the receiving aquatic environment. An efficient method to remove hydrocarbons from water resources is adsorption. In this study, water soluble N,O-carboxymethyl chitosan (NO-CS) was synthesized by carboxymethylation of chitosan in a hydro-alcoholic medium at 50°C by chloroacetic acid. The polymer was characterized through degree...

Cloisite Na+was used as a solid surfactant (stabilizer) in Pickering emulsion polymerization of styrene-co-butyl acrylate in presence of oil soluble initiator, azobisisobutyronitrile (AIBN) and water soluble initiator, potassium persulfate (KPS). Fourier transform infrared (FTIR) spectrum approved the corporation of Cloisite Na+ layers within the polymer matrix. Effect of clay content was a...

Oils enriched in monounsaturated fatty acids do not seem to behave similarly in protecting against the development of atherosclerosis in animal models, which has been attributed to the presence of soluble phenolic compounds. To test the relevance of other components of oils in the prevention of atherosclerosis, two olive oils from the same cultivar devoid of soluble phenolic compounds were prep...
