The 27th chapter of the “Inhabitants of the microworld” series is called “Living biofilm”.
Many species of bacteria associate to create films recovering the 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
This is the 27th chapter of a series that will bring to us a video per day during this confinement forced by COVID-19.
We hope that you enjoy this initiative, which gives access to a documentary series for free to the world, and you share it with everyone you think will possibly be interested.
