Some companies use non organic materials to finish basements. Mold will not grow on these non organic materials. Most basements have moisture and this moisture increases with the hydrostatic pressure of the surrounding ground water. Before you cover your walls with anything you need to install a water barrier on your walls and you need to create a way to collect all that water by breaking a few inches of the floor concrete and installing a system that will channel that water away from your basement, sometimes by means of a sump pump. In order to protect your investments, you may need to hire a contractor to finish your walls and floors in your basement.
