Pseudomonas clemancea Pseudomonas clemancea "Pseudomonas clemancea" is a species of "Pseudomonas" bacteria which was first discovered in the North of England. The specific epithet "clemancea" was given by microbiologist Pattanathu Rahman at Teesside University to bestow the CLEMANCE (Clean Environment Management Centre). This bacterium has DNA coding distinct from existing species and has unique properties developed in response to the contaminated soil from which it comes. Surfactants work by reducing surface tension between two liquids or a liquid and a solid. Biosurfactants, surface-active agents of biological origin, have environment-friendly properties; they are bio-degradable, non-toxic and can be made organically using local raw
Surface tension area, a certain amount of energy must be added. Gibbs free energy is defined by the equation , where is enthalpy and is entropy. Based upon this and the fact that surface tension is Gibbs free energy per unit area, it is possible to obtain the following expression for entropy per unit area: Kelvin's equation for surfaces arises by rearranging the previous equations. It states that surface enthalpy or surface energy (different from surface free energy) depends both on surface tension and its derivative with temperature at constant pressure by the relationship.
