Abstract: A variation of Pulse Coulometric Detection (PCD) is described in which the detection potential is scanned in a cyclic fashion during current integration to achieve automatic and virtual elimination of baseline drift caused by surface roughening and changes in pH. The technique is examined at a Au electrode for flow-injection determination of thiourea which is typical of numerous sulfur compounds whose anodic reactions are catalyzed by formation of surface oxide. The baseline decays quickly to a near-zero equilibrium value following start-up and is unchanged for a pH step of ca. 2 units. The technique is concluded to be compatible with pH-gradient chromatography.

Abstract: The present invention is directed to recombinant genes and their encoded proteins which are recombinant flagellin fusion proteins. Such fusion proteins comprise amino acid sequences specifying an epitope encoded by a flagellin structural gene and an epitope of a heterologous organism which is immunogenic upon introduction of the fusion protein into a vertebrate host. The recombinant genes and proteins of the present invention can be used in vaccine formulations, to provide protection against infection by the heterologous organism, or to provide protection against conditions or disorders caused by an antigen of the organism. In a specific embodiment, attenuated invasive bacteria expressing the recombinant flagellin genes of the invention can be used in live vaccine formulations. The invention is illustrated by way of examples in which epitopes of malaria circumsporozoite antigens, the B subunit of Cholera toxin, surface and presurface antigens of Hepatitis B, VP7 polypeptide of rotavirus, envelope glycoprotein of HIV, and M protein of Streptococcus, are expressed in recombinant flagellin fusion proteins which assemble into functional flagella, and which provoke an immune response directed against the heterologous epitope, in a vertebrate host.

Abstract: Coating compositions based on ethylene vinyl acetate polymers have improved compatability with solvents (especially with aliphatic hydrocarbon solvents) hydrocarbon oils, and mineral waxes by blending the EVA with a fatty acid and heating at or above the melting point of the EVA. Furthermore the resultant blends are much more easily emulsified in the presence of cations that blends which have not been processed with the fatty acid. Typically the starting material for the improved product of this invention is a composition comprising a blend of an EVA polymer and a fatty acid which is miscible in all proportions with mineral spirits at 25 DEG C or forms a solution at a level 5% of fatty acid in mineral spirits, such as coconut or palm fatty acids. Also disclosed is that the addition of a salt of an amine acetic acid in sufficient quantity to an acidified salt of zirconium (for example EDTA and zironium acetate) forms a novel emulsifying agent, and this emulsifying system is used advantageously with the described EVA/fatty acid blends.

Abstract: This invention provides an improved process of recovering citric acid from an impure process stream such as fermentation broth by the addition of a strong acid or salts thereof to a concentrated solution of the citric acid. The process provides for essentially one step purification without the waste disposal problems or large capital investment required by either lime sulfuric or solvent extraction recovery processes. The recovery may be further improved by treating the mother liquor remaining after separation of the citric acid crystals to obtain an additional yield. The preferred strong acid is sulfuric acid and the preferred mother liquor treatment is an ion exclusion resin column. While the improved process is particularly advantageous when used as a one-step purification process for citric acid directly from fermentation broth, it may also be used in conjunction with the various impure process streams generated by the lime sulfuric or solvent extraction recovery processes.
