Abstract: A process is provided for destroying formic acid and/or formaldehyde in an aqueous, organic acid waste stream by contacting the stream with a supported precious metal catalyst and passing air or molecular oxygen gas through the solution to promote chemical oxidation. The invention is a safe, practical and cost-effective alternative to bio-system treatment of these compounds using microorganisms. The process of the invention may be practiced in either a batch or continuous mode and, in accordance with the invention, formic acid present in a stream at a level of 3800 ppm and formaldehyde present in an amount of 5800 ppm can be reduced respectively to levels of 200 ppm or less.

Abstract: A method for controlling the ripening of fruits and vegetables as well as a method for controlling senescence of plant tissue is described. The method generally embraces the expression of an ACC metabolizing enzyme in the fruit or other desired plant tissue to inhibit the production of ethylene in the fruit or plant tissue. The use of the ACC metabolizing enzyme ACC deaminase is described in detail. The ripening or senescence process in the fruit or plant tissue is inhibited by the expression of the ACC deaminase gene such that the shelf-life and marketability of the fruit or plant is enhanced. The ACC metabolizing enzyme may be used in combination with other methods for reducing ethylene production in transformed plants to further reduce the production of ethylene in the fruit or plant. DNA constructs containing the ACC deaminase gene are also described.
