Something amazing happened in my kitchen. I created a glass trap for fruit flies to drown using fermented liquid. I also put in some grapes to ferment and help attract fruit flies. It worked great for 1 month, until amazingly a thick slimy Biofilm formed floating on the surface, partially thanks to the grapes decomposing. Amazingly, not only did this now prevent the flies drowning anymore, but helped them started BREEDING maggots on top of the Biofilm! Bacteria and insects worked together to defeat my trap and start breeding together in symbiosis. Amazing.
@@Iluvmushrooms19 Haha yeh as long as it's wet it has the consitency of a Jellyfish and like a human organ or muscle. It's similar in consistency to liver. Very tough but jelly. And it can regrew in 2 weeks or less. Half a centimetre thick.
@@Iluvmushrooms19 I've just discovered, what formed in my mixture is "Mother of Vinegar" which has been used for centuries to produce more Vinegar. The thick rubbery film is a single-cell fungus related to yeast!
How long does it take until attachment becomes irreversible? I understand that it depends on the surface, the bacteria, the environment. I couldn’t find any timing data for any environment. Any data point would help at this point (from ship hulls to surgical tools). Order-of-magnitude estimate would help.
Yes and no. This is a statement on some of the mechanisms that can be observed during biofilm formation but I believe that it is not necessarily true that all apply to the biofilm as an entity and it is certainly not true that all features mentioned apply to all species members of the biofilm. For example, Type IV pili twitching motility, a fascinating feature, is briefly discussed. This would apply to some species but not others. A quick google search yielded a ton of papers concerning the role of pili in early biofilm formation, but I couldn't find anything stating for a certainty one way or another whether they MUST be present. My amateur assumption would be no, but you know what they say about assumptions. Glycocalyx (slime layers and capsules) and fimbriae can also play a major role. These additional layers and appendages can be observed in select species where some will contain them but not others, but my best guess is that this demonstration of all the different functions available just serves to demonstrate the versatility of biofilm formation. I'm still a student so I may be taking some liberties here, and like you I would have liked some more clarity in the description :/
I also think some of the mechanical processes are constant, but only to a certain extent. The little reading that I have managed to do on the subject seems to indicate that early formation always involves the deposition of a sticky matrix and/or "stickiness" of surface appendages like fimbriae, but again I believe this can take slightly different versatile forms depending on precisely what species are present.
Since diabetes is not caused by bacterial infection, the disease has nothing to do with biofilms directly. Diabetes is caused by a disorder of pancreas beta-cells. Type II is related to a metabolic disorder and type I is an autoimmune disease.
