    摘要： 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.

    摘要： The present invention provides methods for producing recombinant peptides in a bacterial host utilizing a mannitol, arabitol, glucitol, or glycerol-inducible promoter, wherein the host bacterial cell that produces the peptide has been rendered incapable of degrading or metabolizing mannitol, arabitol, or glucitol, or derivatives or analogues thereof. The present invention provides bacterial cells that have been genetically altered to inhibit the metabolism or degradation of mannitol, glucitol, or arabitol, or derivatives or analogues thereof. The present invention utilizes mannitol, arabitol, glucitol, or glycerol to induce expression of a target polypeptide from an inducible promoter, allowing for the use of an inexpensive and stable carbon source inducer in the fermentation processes for the production of recombinant peptides.
