Abstract: The invention provides methods and materials related to the production of lactic acid. Specifically, the invention provides methods for producing lactic acid using a crabtree-negative yeast, such as of the Kluyveromyces, Pichia, Candida, Trichosporon and Yamadazmya genera, which have been transformed with a lactate dehydrogenase gene.

Abstract: The present invention is directed to the use of corn steep liquor, which is a co-product of wet corn milling to make fermentation products, which may be used, in animal feeds and fermentation media.

Abstract: There is described a process for preparing a food or beverage composition having sweetness and a low glycemic index that entails incorporating in the composition a low glycemic index product comprising sucrose and an acceptor selected from the group consisting of a sugar and a sugar alcohol having free hydroxyl groups at one or more of carbon positions numbers 2, 3 and 6 that can accept a glucose unit from sucrose, the blend having been reacted with a glucansucrase enzyme. Also disclosed is a process for reducing glycemic index of a food or beverage composition that entails introducing into the food or beverage composition a low glycemic index product comprising a blend of sucrose and a syrup or syrup solids comprising an acceptor selected from the group consisting of a sugar and a sugar alcohol having a free hydroxyl groups at one or more of carbon positions numbers 2, 3 and 6 that can accept a glucose unit from sucrose, the blend having been reacted with a glucansucrase enzyme.

Abstract: A process for producing lactic acid which includes incubating acid-tolerant homolactic bacteria in nutrient medium to produce a fermentation broth with high levels of free lactic acid is provided. An isolated acid-tolerant homolactic bacteria capable of producing high levels of free lactic acid is also provided.

Abstract: This invention relates to fertilizer compositions containing phosphorus that is derived from steepwater, e.g., corn steepwater, and methods of making fertilizer from steepwater. In one implementation, steepwater is mixed with an alkaline metal hydroxide, which is added in an amount effective to precipitate at least about 75% of the phosphorus in the steepwater. A phosphorus-rich precipitate is separated from the steepwater; the precipitate includes an organic phosphorous component and an inorganic phosphorous component, which may include a phosphorous salt of the metal. At least a majority of the organic phosphorus component may be converted to inorganic phosphorous, improving its bioavailability to growing plants.

Abstract: A low phosphorus animal feed and a method for making same by precipitating phytate from steepwater is described.

Abstract: The invention provides methods and materials related to the production of organic products. Specifically, the invention provides various recombinant yeast cells, methods for culturing yeast cells, methods for making yeast cells, nucleic acid constructs, and methods and materials for producing various organic products.

Abstract: Crabtree negative organisms such as Kluyveromyces, Pichia, Hansenula and Candida, are used to make selected organic products such as lactic acid. The organisms are cultured in a first culture medium that includes glucose, under conditions that promote cellular respiration. The organisms are then cultured under a second set of conditions that promote production of the selected organic product. The organisms preferably contain an exogenous lactate dehydrogenase gene.
