Solvent Extraction and Characterization of Neutral Lipids in Oocystis sp.
*Correspondence: Ben Stuart , 122 Stocker Center, Athens, OH, 45701, USA e-mail: [email protected] Microalgae are a favorable feedstock for bioproducts and biofuels due to their high oil content, fast growth rates, and low resource demands. Solvent lipid extraction efficiency from microalgae is dependent on algal strain and the extraction solvent. Four non-polar extraction solvents were evaluated...
متن کاملSolvent effect on the spectral properties of Neutral Red
BACKGROUND The study was aimed at investigating the effect of various solvents on the absorption spectra of Neutral Red, a dye belonging to the quinone-imine class of dyes. The solvents chosen for the study were water, ethanol, acetonitrile, acetone, propan-1-ol, chloroform, nitrobenzene, ethyleneglycol, acetic acid, DMSO and DMF. RESULTS The results have shown that the absorption maxima of d...
متن کاملA Simple Method for Synthesis of γ-Aluminum Oxide Nanostructure Using PEG as a Neutral Surfactant
Nano-sized γ-Al2O3 was synthesized successfully by a simple method using Al2(SO4)3·18H2O as aluminium source and in the presence of polyethylene glycol (PEG 2000). FTIR spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM) were used to characterize the structure and morphology of synthesized powder. The results showed that PEG playe...

متن کاملMelanin, melanin "ghosts," and melanin composition in Cryptococcus neoformans.
Melanin synthesis is associated with virulence for the pathogenic fungus Cryptococcus neoformans. Exposure of nonmelanized C. neoformans 4067 cells to 4 M guanidinium isothiocyanate followed by 6 M HCl at 100 degrees C resulted in complete solubilization of cellular structures. However, exposure of melanized C. neoformans 24067 to the same conditions produced a suspension of black particles. An...
