obstacle

alright. thanks for your response. i'm going to go that it was positive

above is what the mannitol salt agar plate for an unknown I must figure out. That's where you all come in; Is this a POSITIVE (colonies surrounded by YELLOW zones) or NEGATIVE (colonies surrounded by PINK/RED zones)???????? For those of you unfamiliar with the test, the original agar's color was light red/dark pink. Given the fact that half is yellow and half is pinkish, I belive that is can still be considered a positive reaction (yellow zones) since some yellow actually appeared. It seems like we streaked it too much, but you guys be the judge... (ps. i kinda want it to be negative (pink) bc the unknown i believe it is has a negative result) thanks

hmmm alright; my lab partners and i thought it was anaerobic as well, but needed clarification since there was much growth from the bottom of the tube towards the middle. stefan...i guess, as you said, the high cell count of my sample was what probably made it appear to accumulate so much that it created the allusion of it being facultative. thank you!

IMAGE 1 IMAGE 2 this is 2 pics of the same tube; i took two to see if one was better quality than the other. i tried to get as best resolution as possible. The media is thioglycollate broth kept at 48 hours in 37degrees celcius. This tube was not shaken prior to taking the picture (mayb i shouldve done that?) is this microorganism anaerobic or facultative anaerobic? My only concern is obviously what the red circle dictates, but i feel like the growth/settlement is too much for anaerobic THANK YOU!!!!
