This is long shot in a dark room but-

I'm not sure what your method of isolation is for agrobacterium, but if
it is from the root nodules then I would venture a guess that the pink
color is heme from the nodule.

I seem to recall from an intro micro class long ago that the root
nodules appeared pink under the dissecting scope, due to the heme
contained within.

Just a guess-

Best wishes
