  • Polypeptides and biosynthetic pathways for the production of stereoisomers of monatin and their precursors
    Publication number: 20060252135
    Abstract: Monatin and certain stereoisomers of monatin, such as R,R monatin and S,R monatin, as well as salts thereof, are produced using polypeptides and biosynthetic pathways. These polypeptides and biosynthetic pathways are also useful in the production of R-2-hydroxy-2-(indoly-3-ylmethyl)-4-keto glutaric acid, an intermediate that is formed in certain monatin synthesis pathways, including some biosynthetic pathways.

  • Mutant bacterial strains of the genus sphingomonas deficient in production of polyhydroxybutyrate and a process of clarification of sphingans and compositions thereof
    Publication number: 20060121578
    Abstract: The invention relates to mutant strains of the genus Sphingomonas which have a mutation in at least one gene encoding a protein involved in polyhydroxybutyrate (“PHB”) synthesis that allows the mutant strains to produce PHB-deficient sphingans. The invention is also directed to a process for preparing a clarified sphingan solution comprising heating aqueous sphingan solution, in particular PHB-deficient sphingan solution, to a clarification temperature of about 30° C. to about 70° C., and treating the solution with a clarification agent and enzymes. In addition, the invention is directed to a food or industrial product comprising a PHB-deficient and/or clarified sphingan. One particular embodiment of the invention is directed to a clarified, PHB-deficient high-acyl gellan and the processes of making thereof.
