The SLYM-BARTs can be used as a P/A test capable of indicating to some extent the possible population size and the types of slime-forming organisms present in the water sample. Slime-forming bacteria are able to produce copious amounts of slime without necessarily having to use any iron. Iron bacteria also produce slime, but usually it is thinner and involves the accumulation of various forms of iron. BART biodetectors are excellent diagnostic tools to help identify the presence of process disruptors, such as bacteria creating slime layers and limiting disinfection.
