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 forces, including gravity, drops of virtually all liquids would be approximately spherical. The spherical shape minimizes the necessary "wall tension" of the surface layer according to Laplace's law. Another way to view surface tension is in terms of energy. A molecule in contact with a neighbor is in a lower state of energy than if it were alone (not in contact with a neighbor). The interior molecules have as many neighbors as they can possibly have, but the boundary molecules are missing neighbors (compared to interior molecules) and therefore have a higher energy. For the liquid to minimize its energy
