Biosurfactants, as microbial bioproducts, have significant potential in the field of microbial enhanced oil recovery (MEOR). Biosurfactants are microbial bioproducts with the potential to reduce the interfacial tension (IFT) between crude oil and water, thus enhancing oil recovery. This study aims to...
of these solutions was determined using a spectrophotometer (Mapada V-1100) at a wavelength of 660 nm. The experiment was performed in triplicate. The percentage inhibition of precipitation (denaturation of the protein) was determined on a percentage basis relative to the control using the formula:...
Essential oil (EO) extraction is a widespread practice generating huge amounts of solid plant by-products a potential source of bioactive compounds, on the one hand, and a detrimental risk for the environment that needs to be carefully considered on the other hand. The present study aims to ...
2.1. Mineral oil base stocks Mineral oil base stocks are obtained from petroleum mineral oil [18], [35]. They are available and cheap because they are obtained as lube fractions (distillates from the vacuum distillation) during refining of crude oil [36], [37]. Their utilisation do not con...
