NGSS.HS-LS2-3

Protein catabolism took place. Note that CO₂ gas will never be produced during protein catabolism.

Fermentation of sugars took place. Organism fermented glucose, and then moved on to one or both disaccharides. Sulfur reduction did not take place.

NGSS.HS-LS2-3

Organism cannot ferment any of the sugars. Protein catabolism took place. Sulfur reduction did not take place. This is expected from protein catabolic pathways.

This tube indicates sugar reversion.  The organism fermented glucose, but it cannot ferment any of the disaccharides present.  After glucose was used, it switched metabolism to protein catabolism. Sulfur reduction did not take place.
