Pseudomonas citronellolis is a Gram-negative, bacillus bacterium that is used to study the mechanisms of pyruvate carboxylase.

On agar, P. citronellolis forms round white colonies that produce fluorescent green pigments.

It produces a type of hormone that induces plant cell elongation and division, leading to an increase of local available nutrients.

REP-PCR produces the most complex amplified banding patterns, which reflected diversity among the P citronellolis strains isolated from different oily sludge-contaminated soil samples.

The ribotype patterns of the P. citronellolis strains showed multiple amplicons that strongly indicated polymorphism of the rRNA spacer region.

[6] P. citronellolis has also been found capable of the biosynthesis of polyhydroxyal-kanoates from "linear mono- and dicarboxylic acids", a type of bacterial-synthesized polyester.
