Abstract: The present invention concerns a method for production of recombinant human proteins, in which Tetrahymena cells are transformed with recombinant DNA containing at least one functional gene that codes for a human protein, the recombinant Tetrahymena cells are cultured, in which the gene that codes for a human protein is expressed and the proteins are then isolated. The present invention also concerns a corresponding method, in which the gene that codes for a human protein contains a human leader sequence that leads to secretion of the expressed protein.

Abstract: The present invention relates to wood which contains a sorbic acid store and to processes for producing the sorbic acid store in the wood or on the surface of the wood. The present invention also relates to a process for using sorbic acid and its salts for protecting wood from microbially induced degradation.

Abstract: The present invention relates to nucleic acids isolated from Tetrahymena which code for a ciliate-specific triterpenoid cyclase. The inventive nucleotide sequences and the polypeptide sequences derived therefrom demonstrate a surprisingly minimal sequence identity to known isoprenoid cyclases. The invention also relates to the use of nucleic acids for the regulation of triterpenoid cyclase expression in a host organism, as well as the targeted knockout or repriming of the triterpenoid cyclase gene. As a result of the altered expression of the triterpenoid cyclase, it is possible to modify and enrich the levels of multiple unsaturated fatty acids in the host organism.

Abstract: The invention relates to a method for culturing ciliates comprising the steps of placing ciliates and medium therefor in a culture flask; providing said culture flask with a stirrer having a magnetic core, wherein said stirrer is suspended in the top part of the culture flask such that the stirrer does not touch the flask bottom, and wherein the motion of said stirrer is driven by means of a magnetic field; and stirring said ciliates in said culture medium.

Abstract: The invention relates to wood which is impregnated with sorbic acid and/or one or more salts of sorbic acid. Furthermore, the invention relates to a method for protecting wood by treatment with sorbic acid and/or one or more salts of sorbic acid.

Abstract: Acesulfame-metal complexes, formed from a trace element, preferably Fe, Zn, Cu, Mn, Co and 2 molecules of acesulfamic acid by precipitation reaction with the use of suitable salts, are distinguished by a pleasantly sweet taste and are therefore suitable as sweeteners, food supplements and for enrichment of food, medicaments and feeds with trace elements.

Abstract: Compositions which comprise sorbic acid and/or one or more sorbates, and a flavonoid and/or flavonoid derivative, a method for the preparation thereof, and their use.

Abstract: The invention relates to a multifunctional encapsulated biologically active food component consisting of a core which comprises at least one dietary fiber, which core is surrounded by at least one biologically active substance, in which the core and the biologically active substance(s) is (are) surrounded by one or more shell-forming substance(s).

Abstract: Acidified beverages contain an acidulant, a flavor component and a high intensity sweetener mixture of aspartame and acesulfame potassium. The beverages exhibit high flavor, low chemical taste, balanced sourness and superior overall blendedness when the ratio of aspartame to acesulfame potassium is from about 4:1 to about 2:1.

Abstract: A flavored beverage includes a raspberry flavor; as well as a blend of acesulfame potassium with at least one additional sweetener. The dry mix for the beverage has an acid level of between 50 and 75 percent by weight.

Abstract: Colas are prepared by mixing cola flavor, caramel color, and optionally caffeine with carbonated water, aspartame, acesulfame potassium and an acid component wherein the weight ratio of aspartame to acesulfame potassium is from about 1:1 to about 9:1 and (b) maintaining the admixture at a pH of from about 2.5 to about 3.3 with the proviso that the pH is at least about 2.5 or -0.05 R+2.9 whichever is the greater and further wherein the pH is less than about 3.3 or -0.06 R+3.4 whichever is the lesser; where R is the weight ratio of aspartame to acesulfame potassium.
