To determine whether the bacterium is a chemotroph, the best method would be growing the bacterium in a sulfur solution to see if it breaks the inorganic molecules down. Chemotrophs obtain energy by oxidizing inorganic or organic substances, so observing its ability to utilize sulfur would indicate its chemotrophic nature.
