DESCRIPTION OF BACTERIA ABLE TO DEGRADE ISOQUINOLINE IN PURE CULTURE

Isoquinoline is a nitrogen heterocyclic compound that is associated with coal- and oil-derived wastes. Four strains of bacteria able to degrade isoquinoline in pure culture were isolated from sites known to be contaminated with oil. Isoquinoline was used as the sole source of carbon and nitrogen by these isolates. Isoquinoline was initially transformed to 1-hydroxyisoquinoline, which accumulated in the broth culture, and then disappeared. The four strains isolated were Gram negative, aerobic, rod-shaped bacteria with polar flagella. The strains have been presumptively identified as members of the family Comamonadaceae.

Highly efficient electrochemiluminescence of quinoline and isoquinoline in aqueous solution

This paper reports for the first time the strong cathodic electrochemiluminescence (ECL) behavior of quinoline, isoquinoline and their derivatives in aqueous solution with K2S2O8 as coreactant. The effects of K2S2O8 concentration, pH and scan rate on the ECL intensity have been studied in detail. Calculations of the HOMO-LUMO energy gap for the ECL reaction indicated that isoquinoline is more likely to produce an excited state radical ion than quinoline. The effects of different functional groups on the ECL of isoquinoline were then compared and a possible ECL reaction mechanism was discussed. This work provides a simple and sensitive ECL method for the detection of quinoline and isoquinoline, which are important drug intermediates.
