Last week, we observed the results of the test tubes we inoculated. Our unknown, L 25, tested positive for Citrate utilization, meaning it converts citrate to citrite to ammonia! L 25 also tested positive for the Indole test, meaning to produces indole as a byproduct by utilizing tryptophan. L 25 tested positive for oxidase test, changing the swab instantly purple like Sarah Bartnicki's hair! L 25, an amazing unknown, was positive for nitrate reduction, because it is a facultative anaerobe, it can reduce nitrate completely into molecular nitrogen! L 25 tested negative for urea hydrolysis, meaning it does not hydrolyze urea, a molecule used to excrete nitrogen in urine.
Enjoy the pictures, L 25 is almost identified!
