I am making a planet and my crust is rich in gallium and its heavy counterpart, indium from a cosmic fluke (gallium and indium are both at a concentration of about 0.01% in the crust). However, most gallium and indium compounds range from toxic to possibly carcinogenic for almost all life on Earth, so I need a way to neutralize the stuff.
My idea was to have a bacterium in a symbiotic relation with almost every organism that used enzymes to separate gallium and indium from the minerals they naturally occur in and bind the ions to tin to create a version of galinstan, which is almost totally non-toxic and safe. From there, the stuff would be stored in specialized vacuoles and excreted.
However, galinstan is totally synthetic from my understanding so could this work? If so, is it practical? If not, are there any other alternative ways to deal with the gallium and indium in my crust?
FYI, I just want to know how to deal with the elements. I know that some adaptation would occur obviously in the life forms but I want to know some ways it could happen.
Part two is here.
