Question about nitrate reduction test

Assignment Help Biology
Reference no: EM1388079

Assume you remove your test cultures from the incubator and notice that one of them- a know 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. Adding reagents produces no change, and neither does adding zinc. Is this occurrence consistent with what you have learned about this test? Why?
