Pseudomonas fluorescens Pseudomonas fluorescens
Pseudomonas fluorescens grown on blood agar at 30° C for one day. P. fluorescens is obligately aerobic.
Microscopic image (phase contrast) that shows that the P. fluorescens is relatively long rods.

There is prepared a dilution series of Pseudomonas fluorescens, which is seeded into the PCA and incubated aerobically at 25° C for three days. P. fluorescens is obligately aerobic, but low oxygen tension in the PCA is high enough to allow growth. Colonies located on the surface is relatively large, lobed, probably because the P. fluorescens is very motile. Colonies which is located in the agar are lenticular and opaque, whereas colonies that are adjacent to the bottom are transparent.

There is large lobed surface colonies, less transparent colonies which lies adjacent to the bottom and lenticular colonies which lies in the middle of the agar.
