Trying to make do with what I have here in the lab...can K. pneumoniae grow and be sustained in a litmus milk? Or is that more just for testing. I don't have the exact agars to grow it on and am just trying to see what I can grow it on with the things I do have. We have to use it for a capsule staining lab, and then we'll need it again for gram staining next week. So just wondering the best way to preserve it until next week.

How long do you want to sustain the culture? You can keep K. pneumoniae going in litmus milk for a few days. It's essentially milk after all.

I would need to sustain it for a week.

Does it have to be the same culture going for a week? Or can you just innoculate a fresh flask every couple of days?

i could probably inoculate every couple of days. I've got some going on a TSA slant to see how that will go. Just to test things out.

If you have TSA, why bother with the litmus milk?
