A Tween 80 hydrolysis test substrate was found to be stable at room temperature for at least 6 months.
In biocatalytic conversions, substrates and products may display inhibitory or toxic effects on the biocatalyst. Rhodococcus erythropolis 1awq could further remove sulfur from hydrodesulfurized diesel oil, and the biodesulfurization was enhanced by the surfactant Tween 80. Tween 80 was shown to decrease the product concentration associated with the cells, reducing product inhibition.
The structures of micelles of the surfactant polysorbate 80 (Tween 80) in 0-50% aqueous dimethyl sulfoxide (DMSO) solutions (pH 7.2, ionic strength 2.44 mM) were investigated by means of small-angle X-ray scattering. At DMSO concentrations of 0-20%, core-shell cylinder micelles formed, and at 30-50% DMSO, core-shell discus micelles formed, that is, changing the hydrophobicity of the DMSO solven...
In this paper, we work on extending a Chinese thesaurus with words distinctly used in various Chinese communities. The acquisition and classification of such region-specific lexical items is an important step toward the larger goal of constructing a Pan-Chinese lexical resource. In particular, we extend a previous study in three respects: (1) to improve automatic classification by removing dupl...
The structures of micelles of the surfactant polysorbate 80 (Tween 80) in 0-50% aqueous N,N-dimethylformamide (DMF) solutions (pH 7.2, ionic strength 2.44 mM) were investigated by means of small-angle X-ray scattering. At all the tested DMF concentrations, core-shell cylinder micelles formed; that is, increasing the concentration of DMF did not result in changes in the shape of the micelles. Th...
مقدمه : زگیل یکی از شایع ترین بیماری های پوستی است که توسط ویروس پاپیلومای انسانی ( hpv) ایجاد می گردد . بیشتر ضایعات سیر خود محدود شونده داشته و ظرف دو سال از بین می روند ولی گاهی نیز به مدت طولانی تری در سطح پوست باقی مانده و به سایر افراد یا سایر نقاط پوست منتقل می شوند . روش های درمان این بیماری متنوع بوده و شامل استفاده از کراتولیتیک ها مانند اسید لاکتیک و اسید سالسیلیک ، روش های فیزیکی ما...
