摘要:
A composition-of-matter for use in water treatment, composed of a water-insoluble matrix and one or more amidohydrolase, such as cyanuric acid amidohydrolase, incorporated in or on the matrix, is disclosed. Also disclosed are devices containing same and methods utilizing same for water treatment. The water treatment is effected by an enzymatically-catalyzed reduction of the concentration of an amide-containing compound, such as cyanuric acid, found in chlorinated water of swimming polls, spas and other similar structures.
摘要:
Disclosed are transformed cells and related nucleotide and protein sequences, and fermentation compositions and methods, all of which are related to providing selective advantage in fermentation. For example, a selective advantage results from transformation of a cell with a nucleic acid that allows a transformed cell to metabolize one or more nitrogen-, phosphorous-, and/or sulfur-containing compounds that a native cell of the same species as the transformed cell cannot metabolize, and from fermentation of the transformed cell using one or more feedstocks, such as fractioned grain, which are depleted in or free of conventional nitrogen-, phosphorous-, and/or sulfur-containing compounds that a native cell of the same species as the transformed cell can metabolize. Also disclosed are methods for improved oxygen transfer in an aerobic or microaerobic fermentation.
