- CGSC#: 5017
- Strain Designation
- Sex(Hfr,F+,F-,or F'): F-
- 10 Mutations:
- Comments:
- EMG8 Clowes & Hayes Lab Manual.
- The strain gives a weak positive reaction on MacConkey-Mtl medium. The mtl-2 marker is not known to have reverted in other strains but it is possible that this strain is mtl+.
- This strain gives a strongly positive reaction on MacConkey-Ara medium. the ara-13 marker has reverted in many other strains and we conclude that it has reverted in this strain as well.
