I practiced with Proteus vulgaris . We did this so that we could practice on a culture before we tried to find an unknown. So the first thing I did was inoculate the different sugars to test for carbohydrate fermentation. Then I inoculated an indole vial and glucose vial to test for tryptophanase and gelatinase respectfully. Lastly I stabbed an agar culture to test for motility. I also spread
