What you have learned about this test and why

Suppose you remove your test cultures from the incubator and notice that one of them – a known fermenter – has a gas bubble in the Durham tube. Knowing that fermenters frequently produce gas, you ignore the bubble and proceed to the next step. AIDing reagents produces no change, and neither does aIDing zinc. Is this occurence consistent with what you have learned about this test? Why?
