BioFilms

[darkwng]

Biofilms are a very important bacterial culture to understand.. they play important roles in tooth decay and also in the decay of even water pipes!

Please post your comments here regarding these strange bacterial colonies of growths...

hi
when the bacteria grow in the form of colonies then they get a selective advantage hy division of labor, and also when different type of bacteria grow in colony they secrete exopolysaccharides that give the biofilm great strength so that they are very difficult to remove.
bacterial biofilm are cause of decay of many things on they form because when a biofilm is settled it is very difficult to remove that. Actually biofilim are formed on the solid liquid interface and in this way they get their nutrients from the liquid in most of the case which touches and bath them and with the passage of time they also got streangth huge enough they they resist the cleaning even by good detergent.
now the work is being done on a phenomenon that is used for signalling among the members of bioflim and it is called quorum sensing, so now scientists are working to design some drugs that distrub the quorum sensing and hence reuslt in disruption of biofilm.
there is always need to add more in some topic so.............

There is a medical offshoot here too! People are trying to isolate some harmless bacteria which can help anchoring some intra-medical devices into the patient body! Their formation is also important for many waste water treatment systems.
