Any chelator should have a quite strong bonding to the metal to be bonded. It should be able to release the metal from the bonding inside the body in order to be able to exert a curative effect or it should be present in a very large (over)dose. I very much doubt that such a situation may occur when using bacteria as chelators.

Perhaps bacteria can play a role in preventing as they than can do their work in the intestinal contents before absorption by the body.

Nutritional balancing does not involve using synthetic drug chelators such as EDTA, deferoxamine or IP-6.  They are not needed and have many problems that are discussed below.  Natural chelating agents are also used very rarely, such as high-dose vitamin C.  Vitamin C can increase iron absorption.

Small amounts of vitamin C and sulfur-bearing amino acids such as L-taurine, L-cysteine and L-methionine may be used at times.  Related products such as ALA (alpha lipoic acid), NAC (N-acetyl cysteine) and others could be used, but we find them unnecessary and that they add cost and inconvenience to the programs, and often unbalance the programs because they are too yin in Chinese medical terminology.

Once again, all supplements must be given in a way that does not unbalance the oxidation rate, as this will slow or even stop progress rather than enhancing it.

Which kind of toxic metals? Did you  measure metals content in livestock flesh? I don't think you can chelate toxic metals in livestock using bacteria, maybe the environment in which they live can be subjected to bioremediation...

but Could you please give us more informations? Responses could be more appropriate after that
