Thanks for all your suggestions, Judy!

It does stain the same color as E.coli. It may not be completely clear
from my pictures, but this is caused by bad equipment. So I find it hard
to believe it's a Gram-positive strain.

I couldn't do this since my object was to contain the growth in the
small area behind the red line. The point with this picture was to show
that I have managed to keep the bacteria from spreading.
After this picture was taken I did it once more on a bigger area, and
obtained distinct, single colonies. They all looked the same.

I have to admit I don't have a lot experience with Gram staining, but I
think I got it right ;) Anyway, as soon as I get the results from 16s
sequencing we will now for sure.
