Food-grade microemulsions containing oleic acid, ethanol, Tween 20, and water were formulated as a carrier system for tea seed oil (Camellia oleifera Abel.). The effect of ethanol on the phase behavior of the microemulsion system was clearly reflected in pseudo-ternary diagrams. The solubilization capacity and solubilization efficiency of tea seed oil dispersions were measured along the dilutio...

Uniform-sized agarose beads were prepared by emulsification technique in this study. Agarose (4% w/v) was dissolved in boiling water containing 0.9% sodium chloride and used as water phase. A mixture of liquid paraffin containing 3 wt% of tween 80 emulsifier was heated to 70-80 o C and used as oil phase. Then the heated oil phase was poured into the water phase and the mixture was stirred with ...

To improve the deproteinization (DP) efficacy of shrimp shell powders (SSP) for preparing chitin, Serratia marcescens B742 mutants were prepared using 2% diethyl sulfate (DES), UV-irradiation, and/or microwave heating treatments. Both single-stage and multi-stage mutations were investigated for optimizing S. marcescens B742 mutation conditions. Under the optimized mutation conditions (2% DES tr...

Germination of spores of the fungus Botryodiplodia theobromae was inhibited by the antilipogenic antibiotic cerulenin. The spores remained viable in the presence of the antibiotic, however, and after prolonged incubation they were able to overcome the inhibition. Cerulenin inhibition of germination was reversed by Tween 40 and Tween 60 (derivatives of palmitate and stearate, respectively), but ...

A total of 111 Candida isolates representing 11 species were examined for their respective responses to a Tween 80 opacity test. The strains of Candida albicans and C. tropicalis that were examined produced an opacity response around their colonies at 2 to 3 days postinoculation. A second group of Candida species yielded a halo around their colonies at 8 to 10 days postinoculation. The remainin...

The aim of the study is to determine antioxidant, anti-inflammatory and hypolipidemic activities extracts from Cosmos bipinnatus Cav. three varieties, obtained by extraction with 70% ethyl alcohol. Materials methods. antioxidant effect was studied in vitro using a model iron-induced lipid peroxidation lecithin liposome system. activity carried out on 30 male rats “Wistar” line. Diclofenac used ...
