The application of advanced oxidation processes (AOPs) to the treatment of an effluent contaminated with hydrocarbon oils was investigated. The AOPs conducted were Fe2+/H2O2 (Fenton's reagent), Fe2+/H2O2/UV (Photo-Fenton's reagent) and UV-photolysis. These technologies utilize the very strong oxidizing power of hydroxyl radicals to oxidize organic compounds to harmless end products such as CO2 ...

Fatty-acylated sericin {1:0.7 molar ratio of sericin (Mr 18,700) to oleic acid} was prepared by lipase-catalyzed solid-phase synthesis in n-hexane containing oleic acid to endow sericin with interfacial properties. Acylation with oleic acid was confirmed by 1H-NMR. The fatty-acylated sericin exhibited superior emulsifying activity index and emulsion stability in the presence of 0-0.5 M NaCl, in...

The aim of the research work was to isolate biopolymer and to evaluate its emulsifying ability by formulating o/w type of emulsion. The biopolymer was isolated from the fruit pulp of Prunus insititia by treating with water. The aqueous extract was treated with an optimized ratio of dimethyl ketone and kept in refrigeration for 6 hours. The biopolymer was collected by centrifugation, dried and s...

Liver complication is a major concern in the world. Finding out new way to combat various liver diseases very much required. Ginger has been reported have hepato-protective activity. Here we aimed formulate an oil-based (self-micro emulsifying) powder improve hepatoprotective activity of dry Zingiber officinale (Ginger). Four different formulations self-microemulsifying were prepared by mixing ...

Gallic acid (GA), rutin(R), quercitin (Q), ellagic acid (EA) and sitosterol(S) isolated from the methanolic extract of the leaves of Tectona grandis were formulated as 0.2 % ointment in emulsifying base and were evaluated for their wound healing activity. The animals were divided into eight groups of six animals each. Groups 1 used as control, group 2 used as a standard i.e. nitrofurazone ointm...

When the concentration of the antibiotic cerulenin was increased up to 3.0 mg/l in medium containing ethanol as a carbon source, the specific growth rate of Acinetobacter calcoaceticus and the fatty acid content of the emulsan decreased from 0.179 h(-1) and 13.9% to 0.015 h(-1) and 3.4%, respectively. The emulsifying activity in medium containing cerulenin decreased with increasing cerulenin co...

Gluten hydrolysate was prepared through limited enzymatic hydrolysis of wheat gluten resulting from the byproducts of wheat starch. The enzyme applied in the present study was Protamex. Response surface methodology was used to investigate the effects of pH, gluten hydrolysate (GHP)/ -carrageenan ( C) ratio and reaction time on emulsifying properties of the GHPC conjugate. The regression model f...
