Summary
The effect of fulvic acid on the growth of a benzoate-metabolizing Arthrobacter sp. has been studied. The Arthrobacter grew exponentially with benzoate and fulvic acid but if fulvic acid was omitted then growth was progressively slower and catechol accumulated. These results indicated that fulvic acid enhanced the synthesis of catechol-1,2-oxygenase. Catechol-1,2-oxygenase activity measurements support this suggestion. re]19750822
