This paper deals with the effect of Tween 80 and ergosterol supplementation to the 24oPt wort with 30% maltose syrup adjunct on the fermentation performance of the immobilized yeast in calcium alginate gel. The higher the content of supplements in the wort, the higher the yeast growth, the sugar and free amino nitrogen consumption rates and the ethanol production rate but the lower the ethanol ...
Chitosan, a natural biodegradable polymer is recommended for development of nanoparticles intended for chronic infection such as tuberculosis. Formulation and processing variables play a critical role in the formation of nanoparticles prepared with chitosan. The present study investigated the influence of polymer (chitosan) molecular weight, stabilizing agent (tween 80) concentration and stirri...
In this study, the effects of the addition of Tween 80 and acetone on secretion, structure and antioxidant activities of Lentinus tigrinus exopolysaccharides (EPS) were investigated. It was found that Tween 80 and acetone displayed a stimulatory effect on EPS secretion. The EPS obtained by the addition of Tween 80 (EPS-T), acetone (EPS-A) and control (EPS--C) were purified by Sepharose CL-6B ge...
Цель работы – исследование влияния параметров синтеза на средний гидродинамический радиус мицелл витамина E (альфа-токоферол ацетат). Проводили многофакторный эксперимент, включающий три входных параметра и уровня варьирования. В качестве выбраны: температура (t), концентрация (С (Е)) ПАВ (Tween 80 или Kolliphor HS 15) С (ПАВ). выходного рассматривали (Rср). рамках исследования E, стабилизирова...
Plackett-Burman design was used to efficiently select important medium components affecting the lipase production by Aspergillus niger using shea butter cake as the main substrate. Out of the eleven medium components screened, six comprising of sucrose, (NH4)2SO4, Na2HPO4, MgSO4, Tween-80, and olive oil were found to contribute positively to the overall lipase production with a maximum producti...
Leishmaniasis is a disease caused by the intracellular protozoan, Leishmania. A current treatment for cutaneous leishmaniasis involves the delivery of imidazoquinolines via a topical cream. However, there are no parenteral formulations of imidazoquinolines for the most deadly version of the disease, visceral leishmaniasis. This work investigates the use of electrospray to encapsulate the imidaz...
The dihydropyridine receptor-calcium channel complex, prelabeled with (+)-[3H]PN200-110, was solubilized from rat heart membranes with a detergent mixture of digitonin and Triton X-100. The dissociation of (+)-[3H]PN200-110 was slow enough to permit the hydrodynamic characterization of the complex by means of sucrose gradient sedimentation and gel filtration. The hydrodynamic properties of the ...
