Abstract: | Aromatic carboxylic acids substituted with methoxylated groupsare among the most abundant products in alpechin, the wastes resulting from pressing olives to obtain olive oil. Degradation of o-methoxybenzoate by an stable consortium made of a grampositive bacterium, Arthrobacter oxydans, and gram negative one,Pantotea agglomerans, was shown to mineralize this compound efficiently. he concerted action of both microorganisms was needed for the two first steps n the process, namely, the conversion of o-methoxybenzoate into salycilate,and the hydroxylation of the latter to gentisate. Gentisate was further degraded by the Arthrobacter strain. |
