Mold on the surface can be treated with bleach; but you're never gonna cure it if it was truly watersoaked. Cut out the soaked portions, allow the walls to dry, and then reinstall. Floating drywall is not as hard as it seems and you'll get better each time you do it.

Since you don't state the substance of the wall (No offense, but details are important) I recently did a job replacing every bit of drywall in an 44,000 sq. ft. building. It had flooded and eventually the water was under control but black mold had taken over.
To answer your Q directly: You Can't "Treat" it. Straight bleach or clorine will only moderately clean it.
The mold has no effect on the pressed gypsum, but attacks the paper on both sides of the drywall, as well as any paint. Most especially in the case of drywall that has been soaked it should be removed anyway, as sooner or later it will warp and distort, IF it ever drys. As long as the gypsum stays damp however, the black mold has an ideal enviornment to thrive in.

An added thought. In the re-install allow that the new drywall is off the floor level by at least an inch, in case the WET came from flooding. I installed all mine at 2 inches off the floor.

if the water was soaked all the way through you probably have the mold also growing on the back side take a plug out and make sure you don't have mold on the back if you do you need to remove the drywall if not clean with a strong bleach solution make sure you use a respirator (not paper) after you have it clean use a dehumidifier to dry it out

Mix 1 part bleach and 9 parts water in a spray bottle. Spray the moldy area, let it dry. You may have to repeat this a few times to make the mold disappear. You may also want to have this checked for a toxic mold. Some molds can be deadly to humans.

Don't mess about with half measures, if the water problem has been resolved, strip out the drywall, place a dehumidifier insitu until completely dry, then re-instate drywall and finish. Believe me if you patch and repair without drying the whole area you will have a reoccuring mould problem

Honestly... the only way is to cut it out. You should see how far up the wall the mold has traveled and use a snap-line to get a straight-line reference. Then, a hand saw or a jig saw works best. Be careful not to cut through any electrical wires though.
That is it. Get it out.

Unless you want to risk contaminating the entire house with mold spores, you don't take this on as a do-it-yourself project.
You must call in a proper contractor who will be able to assess the situation & take steps to contain the spores.

Remove everything and put up new dry wall. Thats the only way to deal with mold.

Rip the drywall out and replace it with blue board.
