if a microbe gives a fermentative result ina lactose fermentation tube what result would you expect ina glucose fermentation tue? can you predict this result without does the test?
ANS: Both tubes in an OF test would be yellow, which could indicate two things: it can be either fermentative (F) or both oxidative-fermentative (O-F), which would indicate glucose fermentation and lactose fermentation. If a microbe can metabolize lactose or even sucrose, it must be able to ferment glucose. Lactose and sucrose, which are polysaccharides, are made up of glucose, a monosaccharide.<br> So yes, you can predict this result without doing the glucose fermentation tube test.
