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 walls of its container, we consider the part of the fluid's surface area that is in contact with the container to have "negative" surface tension. The fluid then works to maximize the contact surface area. So in this case increasing the area in contact with the container decreases rather than increases the potential energy. That decrease is enough to compensate for the increased potential energy associated with lifting the fluid near the walls of the container. If a tube is sufficiently narrow and the liquid adhesion to its walls is sufficiently strong, surface tension can draw liquid up the tube
