Colonies of Xanthomonas phaseoli pv. phaseoli (MT plates), with a fuscan power. The two images seem different just because of the different colour background between them. Small flakes in the agar are normal.


growth time: 6 days | temperature: 28°C | lighting: dark | agar: MT ( ) |
DNA testing: Reference isolate
