The facile preparation of a novel 8-membered polyhydroxylated salicylic acid lactone from 2,6-dihydroxybenzoic acid and sodium thio-D-glucose is described. The key step involved a sodium hydride promoted intramolecular lactonization in the presence of excess TMSCl, which led to isolation of
The paper mainly focused on illustrating the merit of respirometric analysis in assessing the inhibitory/toxic impact of xenobiotics on substrate biodegradation. It also evaluated biodegradation characteristics of these chemicals at continuous exposure through acclimation ofthe microbial culture. The nature and

This study evaluated the kinetics of 2,6-dihydroxybenozic acid and peptone biodegradation at low sludge age by acclimated culture under aerobic conditions. A laboratory-scale sequencing batch reactor was set and fed with peptone mixture. The system was operated at steady-state at

We identified a gene cluster that is involved in the gamma-resorcylate (2,6-dihydroxybenzoate) catabolism of the aerobic bacterium Rhizobium sp. strain MTP-10005. The cluster consists of the graRDAFCBEK genes, and graA, graB, graC, and graD were heterologously expressed in Escherichia coli.

A nonoxidative decarboxylase, 2,6-dihydroxybenzoate decarboxylase, was found in Agrobacterium tumefaciens IAM12048. The enzyme activity was induced specifically by 2,6-dihydroxybenzoate. The purified enzyme was a homotetramer of identical 38 kDa subunits. The purified decarboxylase catalyzed the nonoxidative decarboxylation of 2,6-dihydroxybenzoate and
