Delftia lacustris is a Gram-negative, nonfermentative, motile, rod-shaped bacterium from the family Comamonadaceae, which was isolated from mesotrophic lake water in Denmark.

[5] The LC-Z strain of Delftia lacustris isolated from polluted wastewaters is able to degrade naphthalene, 2-methylnaphthalene, benzene, and toluene.

[4] Co-cultures Delftia lacustris with Phanerochaete chrysosporium could be used for the bioremediation of petrochemical wastewaters by simultaneously neutralizing selenite and phenols.

[7] Delftia lacustris has been reported as a causative agent for nosocomial bacteremia, endocarditis, keratitis, and ocular infections.

[9][10] Infections caused by D. lacustris, D. acidovorans, and D. tsuruhatensis are difficult to distinguish using commercial methods and are often mistaken for one another.
