NOVELTY - Control of odor production in waste containing fecal matter, urine or a combination of both comprises adding and mixing a composition containing a viable Pseudomonas sp. into the waste. Pseudomonas sp. is isolated from hog manure and degrades ammonia at a level at least 500 ppm (parts per million) of ammonia in waste matter.    USE - The methods and compositions are useful for controlling fecal odor production that develops from waste containing urine or fecal matter (claimed). The methods and compositions are useful for reducing the production of offensive odors, particularly by reducing the amount of ammonia produced, and degrading skatole and manure from agricultural wastes, which accumulate because of the scale of hog and chicken farming. In addition to reducing offensive odors emanating from waste sites, the methods and compositions are also useful in reducing buildup of animal waste products. The isolates PPU 9.0 and PFL 2.1 comprising the composition are particularly useful for the assimilation of ammonia into nitrogen containing compounds, thus reducing the loss of nitrogen as ammonia from animal waste.    ADVANTAGE - Prior methods are effective in treating and processing animal waste materials to manage waste and prevent buildup. However, these methods are ineffective in controlling odor production from animal waste pits. The present method is effective in reducing the production of offensive odors, in addition to reducing buildup of animal waste products. The methods and compositions are practical with respect to farm economics, compatible with existing equipment and waste holding facilities, do not require the use of additional expensive equipment and are environmentally safe.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a method for control of odor production in waste containing fecal matter or urine or a combination of these comprising:    (a) adding a composition having a viable Pseudomonas sp.;    (b) mixing the composition into the waste; and    (c) aerating the waste to maintain an aerobic environment where the Pseudomonas sp. reduces odor production; or    (d) employing steps (1a-b);    (2) a method for controlling odor production in waste water containing fecal matter, urine or a combination of both comprising:    (a) adding a composition containing viable Pseudomonas sp.;    (b) mixing the composition to the waste; and    (c) aerating the waste to maintain an aerobic environment where the Pseudomonas sp. reduces the production of odor;or    (d) employing steps (2a-b) only; and    (3) a method for controlling fecal odor production in waste containing fecal matter, urine, or a combination of both comprising:    (a) providing a composition containing:    (i) water;    (ii) an alkali metal nitrate in an amount between 0.1-5% by weight of the water and an optional buffering amount of monoammonium phosphate; and    (iii) a Pseudomonas sp.;    (b) holding the composition at a temperature between 8-35 degrees C to provide a preserved bacterium; and    (c) mixing (a) into the waste, where the Pseudomonas sp. reduces the production of odor.
