Guest guest Posted September 7, 2010 Report Share Posted September 7, 2010 Someone asked me to explain how Biofilms and Mycotoxins differ. They can be related but occur for totally different reasons. And we all can learn enough of the basics from Wikipedia or other sites. BioFilm - http://en.wikipedia.org/wiki/Biofilm - A biofilm is an aggregate of microorganisms in which cells adhere to each other and/or to a surface. ... There are biofilms other than with mold, such as dental plaque is a biofilm, as is the " slime " or " slickness " on rocks in streams and rivers. Mycotoxin - http://en.wikipedia.org/wiki/Mycotoxin - A mycotoxin is a toxic secondary metabolite produced by organisms of the fungus kingdom, commonly known as molds. Secondary metabolite - http://en.wikipedia.org/wiki/Secondary_metabolite - means they are created for reasons other than the primary functions of growth, development, or reproduction. Often as a defense against competing organisms. There can be mycotoxins in a biofilm but not all biofilms will have myctoxins. There can be individual areas of mold growth without a biofilm and there can be biofilms without mold growth. If the mold growth, with or without a biofilm, is on a smooth surface then a routine cleaning of the surface will remove the individual colonies of mold growth and any biofilm which may be present. The roots will be in the biofilm and will be removed along with the biofilm, hyphae, conidia, spores, and mycotoxins. No more mold (or bacteria and the other factors of the filth caused by moisture). If the mold growth, with or without a biofilm, is on a rough or porous surface then cleaning the surface will not get into the crevices and pores. Routine surface cleaning cannot remove all the roots, biofiom, hypae, conidia, spores, and mycotoxins. Mycotoxins may remain on a smooth surface especially if there has been a chemical reactions which binds them to the smooth surface. We may have opinions which don't agree with the above, but our opinions cannot change the physical facts of what a biofilm is and what mycotoxins are. Whether mold, biofilms, mycotoxins, bacteria and other filth are sufficiently removed by cleaning is open to discussion. Current testing methods are not absolute which means we can get pristine lab results and people still react the what isn't detected. Or, they are reacting to the cleaning product used to remove the " filth " from the surfaces. Carl Grimes Healthy Habitats LLC Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 8, 2010 Report Share Posted September 8, 2010 I forgot to mention that Wikipedia lists categories of products which contain secondary metabolites. They include Codeine, Morphine, Atropine, Resveratrol, Vancomycin, Bacitracin. Carl Grimes Healthy Habitats LLC ----- Someone asked me to explain how Biofilms and Mycotoxins differ.

Guest guest Posted September 8, 2010 Report Share Posted September 8, 2010 No. Not all secondary metabolites from mold are mycotoxins, not all secondary metabolites are from mold. They can be from any living organism including people. From anything with metabolism.

Guest guest Posted September 8, 2010 Report Share Posted September 8, 2010 Correct Carl. It is sell documented in the literature that bacteria also produce secondary metabolites. Again,. I am seeing a trend where readers are thinking that only toxic molds are present. They need to go through the archives and read yours and my posting on the subject of biocontaminants in WDB.
