Abstract
The water-soluble polyphenols released from the seed coat of the black bean were used to simulate a polyphenol-rich environment and analyze the response of the bean-nodulating strain Rhizobium etli CFN42. The oxidation of polyphenols results in the production of a high quantity of [H.sub.2][O.sub.2], whose removal by the katG-encoded catalase plays a critical role in cell survival in a polyphenol-rich environment.
