Phenotypically, you have discovered that the new bacterial strain can grow in the presence or absence of oxygen. By growing the strain in glucose carbohydrate tubes, you found that the organism is positive for glucose fermentation. After genome sequencing and biochemical analysis, you know that your organism is capable of making all of the enzymes necessary for glycolysis, and that it contains a TCA cycle and an electron transport chain.arrow_forward
