Micro the unknown report
Help! My unknown is gram+ cocci, endospore-forming, and then I went to the nitrate test. I added 5 drops for both reagent A&B first and it didn't turn red but something like light orange. Then I add the Zine. It turned red which below the powder but not the whole tube turn red.. Then I mixed them together. the red is gone and the tube become grey which is the powder's color. SO does it mean it's nitrate - or +.I am confuse because i google what should the "red" look like in this test and it's kind of different. HElP because it will directly affect my result.Sporosarcina ureae or Sporosarcina halophila. OR what other test should I do to identify the unknown
