What can cause a phenol red indicator of carbohydratefermentation to give a false positive with gas?
I heavily incubated my organism in the test tube and it isproducing a huge gas bubble in the Durham tube and a clear yellow(acid) color. I incubated my tube at my organism's optimism growthconditions (oxygen and temperature wise) for 48 hrs exactly.. i wassupposed to get a red no gas result ( -) what might have gonewrong?
