Abstract: Pseudomonas mendocina P2d grew in sodium benzoate at as high as 1% concentration and formed a quinonoid compound, identified as ortho-benzoquinone, that rendered the medium orange to wine-red in colour. The quinone was not metabilised further by the organism. Sodium benzoate was converted to catechol, which was a central metabolite forming ortho-benzoquinone and 2- hydroxymuconic semialdehyde (2-HMS) via.  metaring cleavage pathway.
