To determine whether the unknown bacterium is a chemotroph, you would use the method of growing the bacterium in an agar tube filled with protein to see if it breaks the organic molecules down. Chemotrophs obtain energy from the oxidation of chemical compounds, which can include organic compounds like proteins. Observing whether the bacterium can break down these organic molecules would help establish its nutritional mode as a chemotroph.
