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
Capillary surface and other energy potentials absent, the energy of the system is where the subscripts formula_40, formula_41, and formula_42 respectively indicate the liquid–gas, solid–gas, and solid–liquid interfaces. Note that inclusion of gravity would require consideration of the volume enclosed by the capillary surface and the solid walls. Typically the surface tension values between the solid–gas and solid–liquid interfaces are not known. This does not pose a problem; since only changes in energy are of primary interest. If the net solid area formula_43 is a constant, and the contact angle is known, it may be shown that (again, for two different fluids
