Biological indicators test the effectiveness of the sterilization process of steam autoclaves and gas sterilizers. Spores of the heat-resistant bacterium, Bacillus (Geobacillus) stearothermophilus, test the effectiveness of steam autoclaves. Bacillus subtilis spores are used to test the effectiveness of gas sterilizers.
