Antibacterial Activities of Nonionic and Anionic Surfactants From Citrullus lanatus Seed Oil

antibacterial activities of nonionic and anionic surfactants from citrullus lanatus seed oil

conclusions the biosurfactants inhibited the growth of organisms such as pseudomonas aeruginosa, staphylococcus aureus, klebsiella pneumonia and escherichia coli with diethanolamide biosurfactant exhibiting better antibacterial activity than sulphated diethanolamide. results the iodine and saponification values of citrullus lanatus oil were 118.50 ± 0.80 g iodine/100g and 199.10 ± 2.40 mgkoh/g ...

Microemulsions with Nonionic Surfactants and Mint Oil

A combination of electrical conductivity, dynamic viscosity, dynamic light scattering and small angle X-ray scattering methods was used to study the properties of the water + propylene glycol/mixed nonionic surfactants/ peppermint oil + ethanol U-type microemulsions which can be diluted with any amount of water. The surfactants were sucrose laurate and ethoxylated mono-di-glyceride. The mixing ...

Effects of Several Nonionic and Anionic Surfactants on Cucumber Protoplasts*

The effects of four nonionic and two anionic surfactants on cucumber protoplasts were examined by light and electron microscopy. Two nonionic surfactants, polyoxyethylene (POE) (n=10) nonylphenylether and POE (n=5) laurylether, caused swelling of protoplasts, followed by their bursting. The bursting gave more destructive effects preferentially on lamellar structures of chloroplasts than the swe...

Electrodeposition of anionic, cationic and nonionic surfactants and gold nanoparticles onto glassy carbon electrode for catechol detection

Three surfactants were selected to modify glassy carbon electrode including sodiumdodecylbenzenesulfonate, Tween 80 and cetyltrimethylammonium bromide. The obtained nano-Au/surfactant/GCEs were characterized with scanning electron microscopy and electrochemicaltechniques. Electrochemical behavior of catechol at the nano-Au/surfactant/GCE was thoroughlyinvestigated for mo...
