Living Biofilm - HABITANTES DEL MICROMUNDO

Many species of bacteria associate to create films that cover the wet or submerged surfaces. These films are called biofilms and in some cases they can be a serious problem for example, when appear on the surface of the surgical prosthesis or when blocking the drains of the houses. Nevertheless, in natural environments, such as the surface of trunks and stones submerged in ponds, lagoons and rivers, these biofilms act as great attractors to other organisms which find there a lot of food resources. Ciliates, rotifers, nematodes and flat worms along with some single celled algae as Euglena find in these biofilms an excellent place to live. .
