A gram-negative aerobic motile rod-shaped and non-spore forming bacterium associated to various chemical degradation including citronellol and phenanthrene.


Pseudomonas delhiensis has a size of about 0.56 by 1.5 micrometer with a single polar flagellum used for locomotion. It is isolated from the fly ash dumping site which has a capacity to degrade phenanthrene and citronellol.

Pseudomonas delhiensis in cultured medium shows circular smooth colonies with muddy white and grayish central spot. It is strictly aerobic that grows at temperature ranging from 4’C-41’C.

Pseudomonas delhiensis is positive on nitrate reductase, urease and catalase test while negative on amylase and gelatinase test. Its acid is produced from lactose, mannitol, glycerol, glucose, dextrin, L-arabinose, D-galactose, xylose, sorbitol and sucrose.
