I forget exactly which bacteria this includes, but I know there are some referred to as “hypolipotrophs” that are known for being able to survive on even microscopically-thin films of lipids on otherwise sterile metallic surfaces, and to survive many forms or sterilization and even some degree of autoclaving in this way. It’s estimated that many can actually survive even on the surfaces of otherwise sterile surgical tools (thankfully, none are known to be pathogenic).
