They were showing that without access to any other nutrient&amp;#x2F;carbon source, the bacteria were able to degrade and metabolize a variety of cleaning agents, Kleenol among those tested.&lt;p&gt;That is, they weren’t saying “hey, this bullet is ineffective against that tank.” They were saying, “deprived of oil, that tank started eating bullets.”</text></comment>
