Is it possible for bacteria or fungus to exist in an Argon environment?

Check out a neon or argon filled light bulb. It may have black or brown spots inside that are circular, some large, some small.

These are tungsten deposits that form as the metal filament vaporizes and then condenses on the relatively cool bulb material. These spots will be various sizes depending upon temperatures reached while the bulb is being powered. The condensed clumps can form anywhere around the bulb’s inside surface depending upon temperatures reached.

There is nothing organic about the spots that form inside the bulb.
