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 in a phenomenon known as capillary action. The height to which the column is lifted is given by Jurin's law: where Pouring mercury onto a horizontal flat sheet of glass results in a puddle that has a perceptible thickness. The puddle will spread out only to the point where it is a little under half a centimetre thick, and no thinner. Again this is due to the action of mercury's strong surface tension. The liquid mass flattens out because that brings as much of the mercury to as low a level as possible, but the surface tension, at the same
